I want to move a cursor in EditText with custom left and right buttons. When I click the left button then it should go one character left and when I click a right button then it should go one character right.
I created a simple project for it. To move cursor You just can use this function: editText.setSelection(position). But before calling this function You have to check if You are at the start/end because You can get exception java.lang.IndexOutOfBoundsException.
EditText editText;
Button buttonBackward, buttonForward;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText = findViewById(R.id.editText);
buttonBackward = findViewById(R.id.buttonBackward);
buttonForward = findViewById(R.id.buttonForward);
buttonForward.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
if (editText.getSelectionEnd() < editText.getText().toString().length())
{
editText.setSelection(editText.getSelectionEnd() + 1);
}
else
{
//end of string, cannot move cursor forward
}
}
});
buttonBackward.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
if (editText.getSelectionStart() > 0)
{
editText.setSelection(editText.getSelectionEnd() - 1);
}
else
{
//start of string, cannot move cursor backward
}
}
});
}

I have a problem on getting my imageview button to work onclick. what im trying to do is to make the first image invisible so that the second one behind it can appear and at the same time define int special based on what image that has been clicked.
public class TrainingActivity extends AppCompatActivity implements View.OnClickListener {
public static int special;
public static ImageView a12,b13,a12a,b13a;
#Override
protected void onCreate(Bundle savedInstanceState) {
////////////////////////////////////////////////////////////////////////
super.onCreate(savedInstanceState);
setContentView(R.layout.home_page);
a12 = (ImageView) findViewById(R.id.young);
b13 = (ImageView) findViewById(R.id.old);
a12a = (ImageView) findViewById(R.id.young2);
b13a = (ImageView) findViewById(R.id.old2);
a12.setOnClickListener(this);
b13.setOnClickListener(this);
a12a.setOnClickListener(this);
b13a.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (v.getId() == R.id.young) {
a12.setVisibility(View.GONE);
a12a.setVisibility(View.VISIBLE);
special =0;
} else {
a12.setVisibility(View.VISIBLE);
a12a.setVisibility(View.GONE);
}
if (v.getId() == R.id.old) {
b13.setVisibility(View.GONE);
b13a.setVisibility(View.VISIBLE);
special =1;
} else {
b13.setVisibility(View.VISIBLE);
b13a.setVisibility(View.GONE);
}
}
this is my main class file. I've had already tried this codes in a new project and it works there but somehow doesn't here.

And this is the layout. The problem might happen because of my manifest file but im unsure. Does anyone have any ideas?
Your code seems okay. Just, casting problem i.e. ImageButton to ImageView.
Your code should be as follows:
public class DemoActivity extends AppCompatActivity implements View.OnClickListener {
public static int special;
public static ImageButton a12, b13, a12a, b13a;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_demo);
a12 = findViewById(R.id.young);
b13 = findViewById(R.id.old);
a12a = findViewById(R.id.young2);
b13a = findViewById(R.id.old2);
a12.setOnClickListener(this);
b13.setOnClickListener(this);
a12a.setOnClickListener(this);
b13a.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (v.getId() == R.id.young) {
a12.setVisibility(View.GONE);
a12a.setVisibility(View.VISIBLE);
special = 0;
} else {
a12.setVisibility(View.VISIBLE);
a12a.setVisibility(View.GONE);
}
if (v.getId() == R.id.old) {
b13.setVisibility(View.GONE);
b13a.setVisibility(View.VISIBLE);
special = 1;
} else {
b13.setVisibility(View.VISIBLE);
b13a.setVisibility(View.GONE);
}
}
}
sorry for annoying you but i am in my first step in android programming and need your support
the question is,
i want to change between photos using next and previous Button
i have 3 photos in an array
and 2 button (next and previous )
put when i started my app. i should press next button twice to change the photo
also in previous i should press it twice to change back
hope someone help me to improve the code down
public class SabahList extends AppCompatActivity {
ImageView img;
int[] mario = new int[]{R.drawable.image_a,R.drawable.image_b,R.drawable.image_c};
int n =0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sabah_list);
img= (ImageView)findViewById(R.id.imageView2);
}
public void btu_next(View view) {
img.setImageResource(mario[n]);
if(n<2)
n++;
}
public void btu_prev(View view) {
img.setImageResource(mario[n]);
if(n>0)
n--;
}
}
Here is your logic problem. Your button's function command them set resource first, then increase/decease value, therefore when you click the second time, it will be set as previous increasingly/decreasingly.
public void btu_next(View view) {
if(n < 2)
n++;
img.setImageResource(mario[n]);
}
This answer may helpful to you if you are using normal array added images from drawable

I tried to make ImageView(bul1) disappear when ImageView(Seethrough) is pressed. I get a nullpointer error when i try to run this code. What is wrong with it?
JAVA code
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ImageView seethrough1 = (ImageView) findViewById(R.id.Seethrough);
final ImageView view1 = (ImageView) findViewById(R.id.bul1);
seethrough1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(view1.getVisibility() == View.VISIBLE)
{
view1.setVisibility(View.INVISIBLE);
}
}
});
}
XML code
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:layout_width="match_parent"
android:layout_height="300dp"
android:paddingBottom="6dp"
android:src="#drawable/gun"
android:clickable="true"
android:id="#+id/Seethrough"
android:onClick="next"
/>
<ImageView
android:layout_width="30dp"
android:layout_height="wrap_content"
android:src="#drawable/bullet"
android:id="#+id/bul1"
/>
</LinearLayout>
You need to reconcile seethrough's onClickListener with its onClick XML attribute. I'd suggest removing this line from the xml:
android:onClick="next"
and placing the code inside your next method (if you have one)
public void next (View v){
some code
}
behind or before your visibility checking if, whichever suits you more:
#Override
public void onClick(View v) {
//place some code here
if(view1.getVisibility() == View.VISIBLE){
view1.setVisibility(View.INVISIBLE);
}
//or here
}
I think their is problem with out xml code, please try writing xml as follows,
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="300dp"
android:paddingBottom="6dp"
android:src="#drawable/gun"
android:clickable="true"
android:id="#+id/Seethrough"
android:onClick="next"
/>
<ImageView
android:layout_width="30dp"
android:layout_height="wrap_content"
android:src="#drawable/bullet"
android:id="#+id/bul1"
/>
</LinearLayout>
If it return NullPointerExeption, I think your ImageView is Null, because
setContentView(R.layout.activity_main);
and activity_main.xml is not like contents of your post, check name of layout and try again.
I found out that I was supposed to declare the imageviews inside the method instead of before.
like this
public void onClick(View v) {
ImageView seethrough1 = (ImageView) findViewById(R.id.Seethrough);
Hi I am new to Android development and StackOverflow.
I have an Android WebView application in which a 'starter activity' (just intro text and a button to start main intent) starts my WebView activity, which loads a single URL (this is in the onCreate method).
In this main activity, I have three buttons, one of which opens the same URL in the current activity (effectively refreshing the page). The other two buttons I would like to open two different URLs in the same WebView activity, and I was wondering if/how this is possible.
Here is the main ReadWebpageAsyncTask.java activity code:
public class ReadWebpageAsyncTask extends Activity {
private WebView browser;
protected String urlStrOne = "url one";
protected String urlNewCourses = "url two";
protected String urlFutureCourses = "url three";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_read_webpage_async_task);
browser = (WebView)findViewById(R.id.WebView01);
browser.setWebViewClient(new MyBrowser());
browser.loadUrl(urlStrOne);
}
#SuppressLint("SetJavaScriptEnabled")
public void onClick(View view){
browser.getSettings().setLoadsImagesAutomatically(true);
browser.getSettings().setJavaScriptEnabled(true);
browser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
browser.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
browser.loadUrl(urlStrOne);
}
private class MyBrowser extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView browser, String urlStrOne) {
browser.loadUrl(urlStrOne);
return true;
}
}
#Override
// Detect when the back button is pressed
public void onBackPressed() {
if(browser.canGoBack()) {
browser.goBack();
} else {
// Let the system handle the back button
super.onBackPressed();
}
}
}
And the corresponding XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="left|right"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black">
<Button
android:id="#+id/readWebpage"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/soon"
android:background="#+drawable/custom_button_one"
android:onClick="onClick"
android:text="#string/load_page" />
<Button
android:id="#+id/exitapp01"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/soon"
android:background="#+drawable/custom_button_one"
android:onClick="exitButton"
android:text="#string/exit_button" />
<Button
android:id="#+id/soon"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_toLeftOf="#+id/exitapp01"
android:layout_toRightOf="#+id/readWebpage"
android:layout_alignParentTop="true"
android:onClick="comingSoon"
android:text="#string/future_courses" />
</RelativeLayout>
<WebView
android:id="#+id/WebView01"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="#string/WebView01" >
</WebView>
</LinearLayout>
P.S. Please excuse the terrible naming of everything, I wrote this a while back and haven't gotten around to changing it all.
To clarify, the main URL which is loaded first is the same as the button "readWebpage", and the other two URLs which I would like to be loaded on click are buttons "exitapp01" (what can I say, I am a noob) and "soon".
You can add OnClickListeners to your buttons and switch the url depending on the case:
public class ReadWebpageAsyncTask extends Activity implements OnClickListener{
private WebView browser;
protected String urlStrOne = "url one";
protected String urlNewCourses = "url two";
protected String urlFutureCourses = "url three";
Button reload, exit, soon;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_read_webpage_async_task);
browser = (WebView)findViewById(R.id.WebView01);
browser.setWebViewClient(new MyBrowser());
browser.loadUrl(urlStrOne);
reload = (Button)findViewById(R.id.readWebpage);
exit = (Button)findViewById(R.id.exitapp01);
soon = (Button)findViewById(R.id.soon);
reload.setOnClickListener(this);
exit.setOnClickListener(this);
soon.setOnClickListener(this);
}
#SuppressLint("SetJavaScriptEnabled")
public void onClick(View view){
}
#Override
public void onClick(View view) {
switch(view.getId()) {
case R.id.readWebpage:
browser.getSettings().setLoadsImagesAutomatically(true);
browser.getSettings().setJavaScriptEnabled(true);
browser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
browser.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
browser.loadUrl(urlStrOne);
break;
case R.id.exitapp01:
//Do whatever you want with this button
break;
case R.id.soon:
//Do whatever you want with this button
break;
}
}
}
And remove all the android:onClick="" from your xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"

android:layout_width="100dp"
android:layout_height="50dp"
android:layout_alignParentLeft="true"/>
<Button
android:id="#+id/exitapp01"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_centerInParent="true"/>
<Button
android:id="#+id/soon"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_alignParentRight="true"/>
</RelativeLayout>
<WebView
android:id="#+id/WebView01"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
If The buttons are on Activity You have to set the OnClickListener on all the buttons and within the onClick() do like this:
#Override
public void onClick(View view) {
switch(view.getId()) {
case R.id.[Your first button Id]:
{
//Functionality
}
case R.id.[Your Second button Id]:
{
//Functionality
}
case R.id.[Your first button Id]:
{
//Functionality
}
//End Switch
}
//You also need To Write implements OnClickListener at the Class Definition Of Your activity
I'm making a simple "novelty" app that counts how many sneezes are done, it's more of a fun app that builds up experience until I do my huge project during the summer. I have two buttons, one adds a sneeze and the other clears how many sneezes there currently are. It holds the highest number of sneezes that there were previously. The problem is, the TextViews never update, they only initialize to zero. I used a Toast.makeText() to make sure that the buttons are working (they are). Any help is appreciated. Thanks
Java code:
public class MainActivity extends ActionBarActivity {
private int record_number = 0;
private int current_number = 0;
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
Button add_one = (Button) findViewById(R.id.addone);
Button clear_1 = (Button) findViewById(R.id.clear);
add_one.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
current_number += 1;
Toast.makeText(MainActivity.this, "Button Clicked " + current_number, Toast.LENGTH_SHORT).show();
}
});
clear_1.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
current_number = 0;
Toast.makeText(MainActivity.this, "Button Clicked", Toast.LENGTH_SHORT).show();
}
});
TextView rec_text = (TextView) findViewById(R.id.record_num);
TextView cur_text = (TextView) findViewById(R.id.current_num);
if (current_number >= record_number)
{
record_number = current_number;

rec_text.setText(String.valueOf(record_number));
cur_text.setText(String.valueOf(current_number));

You need to update the text of the TextViews inside the onClickListeners. In fact, all your logic for counting, clearing, and recording the record needs to be done in your onClickListeners (or methods called by them). Right now you only do it once in onCreate, then never again. You can do this in onCreate:
final TextView cur_text = (TextView) findViewById(R.id.current_num);
add_one.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
current_number += 1;
cur_text.setText(Integer.toString(current_number);
}
});
And similar for the other TextView & onClickListener.
You only set the contents of your TextViews once. You should update them every time you get a click event. Specifically:
add_one.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
current_number += 1;
if (current_number >= record_number)
{
record_number = current_number;
rec_text.setText(String.valueOf(record_number));
}
cur_text.setText(String.valueOf(current_number));
}
});
clear_1.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
current_number = 0;
cur_text.setText(String.valueOf(current_number));
}
});
NOTE: if your variables current_number, record_number, cur_text, and rec_text aren't already declared as class member variables, you'll want to do that do that so that they're accessible once you leave the scope of the method you're doing all this in (I assume it's onCreate(...).
What you are going to need to do here is update the labels during the on click events of the button. You currently only update them on activity create. This doesn't execute every time there is a click. Can I answer any questions about the fixed up version below?
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
final TextView rec_text = (TextView) findViewById(R.id.record_num);
final TextView cur_text = (TextView) findViewById(R.id.current_num);
Button add_one = (Button) findViewById(R.id.addone);
Button clear_1 = (Button) findViewById(R.id.clear);
add_one.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
current_number += 1;
if (current_number >= record_number)
record_number = current_number;
cur_text.setText(String.valueOf(current_number));
rec_text.setText(String.valueOf(record_number));
}
});
clear_1.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
current_number = 0;
cur_text.setText(String.valueOf(current_number));
rec_text.setText(String.valueOf(record_number));
}
});
cur_text.setText(String.valueOf(current_number));
rec_text.setText(String.valueOf(record_number));
}
