Hello my name is Hernan so and I am a Android Developer. I make this question because I need insert a google map into a custom dialog I already have my dialog working ok but when I am adding the google map it throws an error in code. This is my code.
Java Code:
package com.sigetdriver.view.popup;
import android.app.Dialog;
import android.content.Context;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager.LayoutParams;
import android.widget.Button;
import android.widget.Toast;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.sigetdriver.R;
public class InsertarDestinoPopup {
private GoogleMap googleMap;
private Context context;
public Dialog dialog;
private Button btnCerrar;
public void dialog(Context _context) {
context = _context;
dialog = new Dialog(_context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.popup_destino);
dialog.getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
try {
// Loading map
initilizeMap();
pintarMapa();
} catch (Exception e) {
e.printStackTrace();
}
btnCerrar = (Button) dialog.findViewById(R.id.btnCerrar);
btnCerrar.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
dialog.show();
}
/**
* function to load map. If map is not created it will create it for you
* */
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap(); // *******ERROR HERE*******
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(context,
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
private void pintarMapa() {
googleMap.setMyLocationEnabled(true); // false to disable
}
}
XML Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<Button
android:id="#+id/btnCerrar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Cerrar" />
</LinearLayout>
I dont know if it is the best way to make a dialog or showing a map into dialog, please I need solve this thanks in advance.
Hernan
You can also use activity as a dialog.Here you can do all normal activity methods.
XML Coding
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/map_view"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
</RelativeLayout>
Java Coding
public class Map extends FragmentActivity {
private View rootView;
GoogleMap map;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setBackgroundDrawable(new ColorDrawable(0));
setContentView(R.layout.map);
this.rootView=findViewById(R.id.map_view);
FragmentManager myFragmentManager = getSupportFragmentManager();
SupportMapFragment mySupportMapFragment = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);
map = mySupportMapFragment.getMap();
}
#SuppressLint("NewApi")
#Override
public boolean onTouchEvent(MotionEvent event) {
Rect rect = new Rect();
rootView.getHitRect(rect);
if (!rect.contains((int)event.getX(), (int)event.getY())){
setFinishOnTouchOutside(false);
return true;
}
return false;
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK)) {
finish();
}
return true;
}
}
Manifest File
Here You change the activity as dialog.
<activity
android:name="com.example.mapindialog.Map"
android:excludeFromRecents="true"
android:launchMode="singleInstance"
android:screenOrientation="landscape"
android:theme="#android:style/Theme.Dialog" >
</activity>
base on your png, it seems like you're using support v4 package,in this case you'll need to replace getFragmentManager with getSupportFragmentManager

I am trying to show results in text view but it's not showing temperature in text view. My device has a sensor,when I set text through the if statement inside oncreate it works. It's just onSensorchanged that is not working, even tried to make toast inside the onSensorChanged but it's not working.

import android.widget.Toast;
public class MainActivity extends AppCompatActivity implements SensorEventListener {
private TextView txtview;
private SensorManager sensormanager;
private Sensor sensOR;
private boolean sensorAvailable;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtview = findViewById(R.id.txtTemp);
sensormanager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
if(sensormanager.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE)!=null){
sensOR = sensormanager.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE);
//txtview.setText("set temp");
sensorAvailable = true;
}else{
txtview.setText("Temparature Sensor is not available");
sensorAvailable = false;
}
}
#Override
public void onSensorChanged(SensorEvent sensorEvent) {
txtview.setText(sensorEvent.values[0]+" °C");
}
#Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
#Override
protected void onResume() {
super.onResume();
if(sensorAvailable = true){
sensormanager.registerListener(this,sensOR,SensorManager.SENSOR_DELAY_NORMAL);
}else{
Toast.makeText(this,"Not available",Toast.LENGTH_LONG).show();
}
}
#Override
protected void onPause() {
super.onPause();
if(sensorAvailable =true){
sensormanager.unregisterListener(this);
}
}

I'm trying to create an application that tracks a user's eyes while driving which will also show turn by turn navigation. There will be a camera preview on the same screen as the maps, similar to the image below, where the camera preview is in the top left and the maps is below
I have a MapBox activity working in a seperate file, MapsActivity.java. I want to run the Mapbox activity inside a fragment in an activty test.java which does the eye tracking.
I have looked at tutorials and online resources but cannot find out how to get it to work for my particular code. Apologies if this is a simple question, this is my first app.

It is not possible to run Activity inside another Activity, in your case you can't run MapsActivity in your TestActivity. This is possible with some other solutions but the easiest one for you is to use Fragments. What you can do is to convert your MakeActivity to Fragment and then place it inside TestActivity. Learn how Fragments and Activities work in Android since you'll be using them a lot.
Here are some links to read:
https://developer.android.com/reference/android/app/Fragment.html
https://developer.android.com/guide/fragments
You can put a Maps SDK for Android map fragment inside of your TestActivity or inside a separate fragment
https://docs.mapbox.com/android/maps/examples/support-map-fragment/
https://docs.mapbox.com/android/maps/examples/?search=fragment
Whenever, I enter the fragment, I am shown a blank space for a few seconds, then the webpage in the WebView shows up. It seems that the ProgressBar does not show.
Here's my XML file for the Fragment the WebView and ProgressBar is in
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".FragmentThree">
<ProgressBar
android:id="#+id/progressbar"
style="#style/Widget.AppCompat.ProgressBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"/>
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent">
</WebView>
</RelativeLayout>
Here is the Java file for the Fragment Java implementation:
package com.example.task1;
import android.content.Context;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import androidx.fragment.app.Fragment;
import android.view.LayoutInflater;
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 FragmentThree extends Fragment {
private WebView webView;
private String URL;
private ProgressBar progressBar;
private OnFragmentInteractionListener mListener;
public FragmentThree(String url) {
// Required empty public constructor
this.URL = url;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_three, container, false);
initMain(view);
return view;
}
private void initMain(View view) {
webView = view.findViewById(R.id.webview);
progressBar = view.findViewById(R.id.progressbar);
progressBar.setMax(100);
webView.loadUrl(URL);
webView.setWebViewClient(new WebViewClient());
webView.setWebChromeClient(new WebChromeClient(){
#Override
public void onProgressChanged(WebView view, int newProgress) {
progressBar.setProgress(newProgress);
}
});
}
// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri) {
if (mListener != null) {
mListener.onFragmentInteraction(uri);
}
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnFragmentInteractionListener) {
mListener = (OnFragmentInteractionListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement OnFragmentInteractionListener");
}
}
#Override
public void onDetach() {
super.onDetach();
mListener = null;
}
public interface OnFragmentInteractionListener {
// TODO: Update argument type and name
void onFragmentInteraction(Uri uri);
}
}
The code is mostly located under the initMain() function for clarification.
Any advice is greatly appreciated, thank you for reading!
Just declare ProgressBar below Webview like this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

android:layout_width="match_parent"

xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".FragmentThree">
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent">
</WebView>
<ProgressBar
android:id="#+id/progressbar"
style="#style/Widget.AppCompat.ProgressBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"/>
</RelativeLayout>
enter image description hereHey guys I'm at the end of my Java 1 class working on my project. We are making a memory/concentration game. My issue is that when I click the easy button for the next activity the app crashes. I have tried using fragments and activities and just can't seem to get it right. I have also tried using the layout I need on my main activity just to see if I could get it to display. Even then it just crashes on startup of the app. Any help would be appreciated.

OK It's not the full crash log you posted but at the top of it I saw roidManifest.xml?. And It's sure that you didn't defined your EasyGame Activity in your androidmanifest.xml so add this line inside application tag,
<manifest package="com....." . . . >
<application . . . >
<activity
android:name=".EasyGame"
android:label="easygame">
</activity>
. . .
</application>
</manifest>
In addition you are trying to cast your ImageButton into Button consider fixing that as well.
Add code below to AndroidManfest
<activity
android:name=".EasyGame"
/>
its simple just add this line to your AndroidManifest
<activity android:name="Activity"/>
The logcat did mentioned that you need to declare your activity within the Android Manifest which you didn't. please read the logcat carefully as it really helps to find what went wrong.
OK, so I had tried all of your guys suggestions which I had were part of the issue, the final issue turned out to that I needed to add my images to the drawable-xhdpi. Thanks for all your help.
Can anyone please help me resolve this error?

What I have tried so far:
Read this this link :
similar question on SO and made the following changes in my project:
1) Included the following imports:
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
2) Made sure that MainActivity extends FragmentActivity
3) Decared getActivity() method inside onActivityCreated() method as nicely suggested here
4) Even the following part is included in my manifest as suggested Here
<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
Still I fail to resolve the issue. Any more insights please?
Thanks!
I guess the reason is that you don't have a default constructor in your Fragment class. You overloaded the constructor, but Fragment needs an empty one.
Empty Constructor for Extended Fragment
If you need to receive arguments in your fragment, do it using a Bundle:
public static YourFragment getInstance(String argument)
{
YourFragment fragment = new YourFragment();
Bundle bundle = new Bundle();
bundle.putString("argument", argument);
fragment.setArguments(bundle);
return fragment;
}
And from activity:
YourFragment fragment = YourFragment.getInstance(argument);
getFragmentManager().beginTransaction().add(R.id.container, fragment, "fragmentTag").commit();
R.id.container has to be an id of your RelativeLayout (remove <fragment/> from it).
If you still want to use a <fragment/> in xml, then here is a suggestion, how to pass an argument there: If I declare a fragment in an XML layout, how do I pass it a Bundle?
