Having code problems from MainActivity to FragmentActivity

Having code problems from MainActivity to FragmentActivity - java

I wrote a simple code in MainActivity with its xml code previously which run successfully. Now, I want to make a fragment and run that MainActivity code in that fragment. I have tried everything, even by combining both codes etc. but all in vain. I'm attaching my MainActivity code below. This is the one I want to use in Fragment. I already know that fragment is like sub-activity of an activity and both have separate xmls too which I also know how to use. Just unable to use my MainActivity code from old app as FragmentActivity in a new app.
1) MainActivity Code which needs to act as a Fragment
package com.ranatalha.userauthority;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
import android.widget.TextView;
public class MainActivity
extends AppCompatActivity
implements GestureDetector.OnGestureListener, GestureDetector.OnDoubleTapListener{
private TextView mytext;
private GestureDetector gestureDetector;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); //this is above two lines cox phly content set hoga tbi agy kam hna na
this.gestureDetector = new GestureDetector(this, this);
gestureDetector.setOnDoubleTapListener(this); }
//******************Upon clicking the button*************************
public void changetextshort(View v) {
mytext = (TextView) findViewById(R.id.mytext);
mytext.setText("Surpriseeee"); }
//******************initializing touch event*************************
#Override
public boolean onTouchEvent(MotionEvent event) {
this.gestureDetector.onTouchEvent(event);
return super.onTouchEvent(event);}
//******************Implements Methods from alt+ins(0) for touch properties*************************
#Override
public boolean onSingleTapConfirmed(MotionEvent motionEvent) {
mytext.setText("I tapped Once");
return false;}
#Override
public boolean onDoubleTap(MotionEvent motionEvent) {
mytext.setText("I tapped Twice");
return false;}
#Override
public boolean onDoubleTapEvent(MotionEvent motionEvent) {
mytext.setText("Double Tap Event Occurred");
return false;}
#Override
public boolean onDown(MotionEvent motionEvent) {
mytext.setText("Down goes");
return false;}
#Override
public void onShowPress(MotionEvent motionEvent) {
mytext.setText("I have pressed");}
#Override
public boolean onSingleTapUp(MotionEvent motionEvent) {
mytext.setText("Single Tap Up");
return false;}
#Override
public boolean onScroll(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {
mytext.setText("I'm Scrolling");
return false;}
#Override
public void onLongPress(MotionEvent motionEvent) {
mytext.setText("I long pressed");}
#Override
public boolean onFling(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {
mytext.setText("I FLINNGED");
return false; }
}
2) Fragment Code (MainActivity is not having any code now except the basic code of Mainactivity like class name and OnCreate code - although I have added Mainactivity code in 3rd point too which needs to be actually almost like that when we make fragments in android app)
package com.ranatalha.userauthority;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v7.app.AppCompatActivity;
import android.view.GestureDetector;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class TopSectionFragment extends Fragment {
public class Top
extends AppCompatActivity
implements GestureDetector.OnGestureListener, GestureDetector.OnDoubleTapListener{
private TextView mytext;
private GestureDetector gestureDetector;
//******************Override method oncreateview for fragment*************************
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.top_section_fragment,container, false);
this.gestureDetector = new GestureDetector(this, this);
gestureDetector.setOnDoubleTapListener(this);
return view; //designing of top section fragment completed
}
//******************Upon clicking the button*************************
public void changetextshort(View v) {
mytext = (TextView) findViewById(R.id.mytext);
mytext.setText("Surpriseeee"); }
//******************initializing touch event*************************
#Override
public boolean onTouchEvent(MotionEvent event) {
this.gestureDetector.onTouchEvent(event);
return super.onTouchEvent(event);}
//******************Implements Methods from alt+ins(0) for touch properties*************************
#Override
public boolean onSingleTapConfirmed(MotionEvent motionEvent) {
mytext.setText("I tapped Once");
return false;}
#Override
public boolean onDoubleTap(MotionEvent motionEvent) {
mytext.setText("I tapped Twice");
return false;}
#Override
public boolean onDoubleTapEvent(MotionEvent motionEvent) {
mytext.setText("Double Tap Event Occurred");
return false;}
#Override
public boolean onDown(MotionEvent motionEvent) {
mytext.setText("Down goes");
return false;}
#Override
public void onShowPress(MotionEvent motionEvent) {
mytext.setText("I have pressed");}
#Override
public boolean onSingleTapUp(MotionEvent motionEvent) {
mytext.setText("Single Tap Up");
return false;}
#Override
public boolean onScroll(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {
mytext.setText("I'm Scrolling");
return false;}
#Override
public void onLongPress(MotionEvent motionEvent) {
mytext.setText("I long pressed");}
#Override
public boolean onFling(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {
mytext.setText("I FLINNGED");
return false; }
}
}
3) MainActivity code (which will incorporate Fragment sub-activity)
package com.ranatalha.userauthority;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
public class MainActivity
extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); }
}

One of the main things to keep in mind when converting code from activities and fragments is that you may have to switch things that use context in them.
This line: this.gestureDetector = new GestureDetector(this, this); is likely one of the things that is giving you trouble.
This:
GestureDetector(Context context, GestureDetector.OnGestureListener listener)
is probably the constructor you are trying to use.
The parameters that are context, will need to be changed from this in an activity to getContext() (or to something that extends Context) in a fragment.
For creating the fragment in the first place:
https://developer.android.com/guide/components/fragments.html
// Create new fragment and transaction
Fragment newFragment = new ExampleFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();
The container mentioned in the code sample is normally something like a FrameLayout.

It is not clear what you mean by "make a fragment and run that MainActivity code in that fragment"...
If you want to start an activity and make it overlay the Fragment you can try the code from MCeley in Start an activity from a fragment
> Intent intent = new Intent(getActivity(), mFragmentFavorite.class);
> startActivity(intent);

Cleaning up a one file project

So I'm working on a project and am using a lot of code or atleast a decent amount all in one file and am wondering if there is a way to clean it up into multiple files. I've only every worked with single file. So when It come to adding more files I'm not really sure how to go about this so I'm gonna ask for help on cleaning up the project. the ideal outcome is to have it more understandable via small chunks in other files to clean up the CoreActivity. or if you see a way to clean up some code into a easier and less exhaustive way of writing it then do fix

The simplest way to split code is to think about Single Responsibility (as per the SOLID principles).
As an example in your code, your touch listener can be separated. This would entail making a class that extended the touch listener's class (View.OnTouchListener) instead of extending an activity.
This block in your code:
m_Preferences.setOnTouchListener(new View.OnTouchListener() {
...
});
Would become MyTouchListener.java:
public class MyTouchListener implements View.OnTouchListener {
Animation ToolbarGone,ToolbarPrefVisible;
int x = 0;
#Override
public boolean onTouch(View view, MotionEvent motionEvent) {
... // keep exactly your same code here
}
}
And then your activity gets changed to:
m_Preferences.setOnTouchListener(new MyTouchListener());

How to create an interface from a class

I am new to Android Programming/ Java I wanted to know how I should add gesture Directions when I already have a class extended to MainActvity?
package #####app.myapplication;
import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.GestureDetector.SimpleOnGestureListener;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.view.MotionEvent;
import android.view.GestureDetector;
import android.support.v4.view.GestureDetectorCompat;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity implements GestureDetector.OnGestureListener,GestureDetector.OnDoubleTapListener{
private GestureDetectorCompat mygesture;
private static final int SWIPE_MIN_DISTANCE = 120;
private static final int SWIPE_MAX_OFF_PATH = 250;
private static final int SWIPE_THRESHOLD_VELOCITY = 200;
#Override
public boolean onSingleTapConfirmed(MotionEvent motionEvent) {
return false;
}
#Override
public boolean onDoubleTap(MotionEvent motionEvent) {
return false;
}
#Override
public boolean onDoubleTapEvent(MotionEvent motionEvent) {
return false;
}
#Override
public boolean onDown(MotionEvent motionEvent) {
return false;
}
#Override
public void onShowPress(MotionEvent motionEvent) {
}
#Override
public boolean onSingleTapUp(MotionEvent motionEvent) {
return false;
}
#Override
public boolean onScroll(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {
return false;
}
#Override
public void onLongPress(MotionEvent motionEvent) {
}
#Override
public boolean onFling(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {
}
#Override
public void onPointerCaptureChanged(boolean hasCapture) {
}
#Override
public boolean onTouchEvent(MotionEvent event) {
this.mygesture.onTouchEvent(event);
return super.onTouchEvent(event);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Context context = getApplicationContext();
CharSequence text = "Welcome to ####";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
WebView vedant = (WebView) findViewById(R.id.vedant);
vedant.loadUrl("http://##.ml");
WebSettings webSettings = vedant.getSettings();
webSettings.setJavaScriptEnabled(true);
vedant.setWebViewClient(new WebViewClient());
this.mygesture = new GestureDetectorCompat(this,this);
mygesture.setOnDoubleTapListener(this);
}
}
I know that to use Gesture Direction I need to :
#Override
public boolean onFling(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {
float velocityY) {
try {
if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH){
return false;
}
// right to left swipe
if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE
&& Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
onLeftSwipe();
}
// left to right swipe
else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE
&& Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
onRightSwipe();
}
} catch (Exception e) {
}
return false;
}
return false;
}
But for which I need to extend another class SimpleOnGestureListener.
As i could not extend to the SimpleOnGestureListener class I thought i could create a interface and then implement it. Is that possible. If so how?

If I understand correctly, you have a GestureDetectorCompat with 2 parameters:
The Context
a listener (GestureDetector.OnGestureListener)
At the moment you do mygesture = new GestureDetectorCompat(this,this); where this is your Activity. But why do you want your Activity to be the listener? You can create a listener in a separated class.
So you can do:
MainActivity
this.mygesture = new GestureDetectorCompat(this, new MyGestureListener());
MyGestureListener
public class MyGestureListener extends SimpleOnGestureListener {
#Override
public boolean onFling(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {
// ...
// Your code
}
}

Webview does not reload

I am using fragments and have added a item on the action bar to refresh webview named airport_menuRefresh but when ever i click it nothing happens. I have 3 tabs. I have tried different methods but neither of them works.
Here is the code of my 1tab(tab1 only contains the not working logic to refresh).
import android.os.Bundle;
import android.os.Handler;
import android.support.v4.app.Fragment;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
public class GamesFragment extends Fragment {
private ProgressBar progress;
private WebView myWebView;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String url = "http://google.com";
int delay = 6 * 1000;
View rootView = inflater.inflate(R.layout.fragment_games, container, false);
myWebView = (WebView)rootView.findViewById(R.id.webViewGames);
myWebView.setWebChromeClient(new myWebViewClient());
myWebView.getSettings().setJavaScriptEnabled(true);
progress = (ProgressBar)rootView.findViewById(R.id.progressBar);
progress.setMax(100);
Handler handler = new Handler();
MyRunnable runnable = new MyRunnable(url, myWebView);
handler.postDelayed(runnable, delay);
myWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView View, String url) {
GamesFragment.this.progress.setProgress(0);
View.loadUrl(url);
return true;
}
});
myWebView.setOnKeyListener(new android.view.View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
WebView webView = (WebView) v;
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
if (webView.canGoBack()) {
webView.goBack();
return true;
}
break;
}
}
return false;
}
});
return rootView;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.airport_menuRefresh:
GamesFragment.this.myWebView.loadUrl("http://google.com");
return true;
}
return super.onOptionsItemSelected(item);
}
public class MyRunnable implements Runnable {
String url;
private WebView mywebview;
public MyRunnable(String url, WebView wv) {
this.url = url;
this.mywebview = wv;
}
public void run() {
mywebview.loadUrl(url);
}
}
private class myWebViewClient extends WebChromeClient {
#Override
public void onProgressChanged(WebView view, int newProgress) {
GamesFragment.this.setValue(newProgress);
super.onProgressChanged(view, newProgress);
}
}
public void setValue(int progress) {
this.progress.setProgress(progress);
}
}
Here is my main Activity:
import android.annotation.TargetApi;
import android.os.Build;
import android.os.Bundle;
import android.support.v4.view.ViewPager;

CharSequence Titles[]={ "tab1", "tab2", "tab3" };
int Numboftabs =3;
#TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
#Override

setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.tool_bar);
setSupportActionBar(toolbar);
adapter = new TabsPagerAdapter(getSupportFragmentManager(), Titles, Numboftabs);
// Assigning ViewPager View and setting the adapter
viewPager = (ViewPager) findViewById(R.id.pager);
viewPager.setAdapter(adapter);
viewPager.setOffscreenPageLimit(2);
// Assiging the Sliding Tab Layout View
tabs = (SlidingTabLayout) findViewById(R.id.tabs);
tabs.setDistributeEvenly(true);
setRefreshActionButtonState(true);
tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
#Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.tabsScrollColor);
}
#Override
public int getDividerColor(int i) {
return 0;
}
});
tabs.setViewPager(viewPager);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
this.optionsMenu = menu;
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
return true;
}
public void setRefreshActionButtonState(final boolean refreshing) {
if (optionsMenu != null) {
final MenuItem refreshItem = optionsMenu
.findItem(R.id.airport_menuRefresh);
if (refreshItem != null) {
if (refreshing) {
refreshItem.setActionView(R.layout.actionbar_indeterminate_progress);
} else {
refreshItem.setActionView(null);
}
}
}
}
}
EDIT
I edited my main activity like this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.airport_menuRefresh:
GamesFragment.myWebView1.loadUrl("http://example.com");
MoviesFragment.myWebView.loadUrl("http://example2.com");
TopRatedFragment.myWebView2.loadUrl("http://example3.com");
return true;
}
return super.onOptionsItemSelected(item);
}
Now its reloading but suppose i click reload on tab1 all 3 tabs reloads! Any solution?

I guess error is in the name of the WebView of your methods. As long as you imported:
import android.view.View;
When in this methow
public boolean shouldOverrideUrlLoading(WebView View, String url) {
// ^-----> UPPERCASE
you make this call:
View.loadUrl(url);
you're trying to call static method of View and not the instance of View from method signature.
try this:
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// ^---> lowercase
GamesFragment.this.progress.setProgress(0);
view.loadUrl(url);
// ^---> lowercase
return true;
}

Finally i found a solution.
Moved onCreateOptionsMenu and onOptionsItemSelected from main activity to fragment tabs like this
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
.............
.............
.............
setHasOptionsMenu(true);
.................
.................
}
#Override
public void onCreateOptionsMenu(
Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_main, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// handle item selection
switch (item.getItemId()) {
case R.id.airport_menuRefresh:
TopRatedFragment.this.myWebView2.loadUrl("http://myexample.com");
return true;
default:
return super.onOptionsItemSelected(item);
}
}
And this worked like a charm.

How to set image as wall paper in viewpager app?

Edited code after following this link ...Set wallpaper from ViewPager .I developed simple viewpager app along with the background music. However, I want to modify my app so that image chosen by user will give them option to set as wallpaper....I don't want to implement any buttons in my app. User should be able to just touch the image , which will give them option to set as wallpaper...

I just start with programming, so please give some explanations, or it will be great if you provide some codes .

First add this Permission to the Manifest
<uses-permission android:name="android.permission.SET_WALLPAPER">
Now for some code.
imageview.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
WallpaperManager myWallpaperManager
= WallpaperManager.getInstance(context);
try {
myWallpaperManager.setResource(GalImages[position]);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
Explantion : This will set that the Image will be clickable , when the image is clicked it will set the phone Wallpaper with the selected drawable.
getApplicationContext()
is the Context from the Activity.
This changes will take place inside the Adapter.
Activity
add this variable
int currentPosition;

play sound while button is pressed -android

i have this code
package com.tct.soundTouch;
import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.Button;
public class main extends Activity implements OnTouchListener {
private MediaPlayer mp;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button zero = (Button) this.findViewById(R.id.button);
zero.setOnTouchListener(this);
mp = MediaPlayer.create(this, R.raw.sound);
}
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
mp.setLooping(true);
mp.start();
case MotionEvent.ACTION_UP:
mp.pause();
}
return true;
}
}
and it works but not as i expected. The sound plays but only for each time that i press the button. My idea is. While i press the button the sound plays, when i stop the action (finger out of the button) music pause.
Any idea please?
thanks

This should work (there was something wrong with your switch-cases I think):
#Override
public boolean onTouch(View v, MotionEvent event)
{
switch (event.getAction())
{
case MotionEvent.ACTION_DOWN:
{
mediaPlayer.setLooping(true);
mediaPlayer.start();
}
break;
case MotionEvent.ACTION_UP:
{
mediaPlayer.pause();
}
break;
}
return true;
}

public class MainActivity extends AppCompatActivity {
Button button;
MediaPlayer player;
#SuppressLint("ClickableViewAccessibility")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.activity_main );
button = findViewById( R.id.Click );
button.setOnTouchListener( new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction()== MotionEvent.ACTION_DOWN) {
player= MediaPlayer.create( MainActivity.this,R.raw.horn );
player.start();
}
else if(event.getAction()==MotionEvent.ACTION_UP){
player.stop();
player.release();
}
return true;
}
} );
}
}
