Intent et MapView

Bonjour

Je souhaite utiliser un Intent pour lancer une application héritant de la classe MapActivity.

Pour le test, ma première application (Test) a un bouton qui lance via un Intent lance la deuxième application (TestView)

Code:

1
2
3
4
5
6
7
8
9
10
11
12
public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button bt = (Button)findViewById(R.id.Button01);
        bt.setOnClickListener(new Button.OnClickListener(){
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				Intent intent = new Intent(Test.this, TestView.class);
		        startActivity(intent);
			}
        });
    }

Tant que la deuxième application hérite de Activity, son lancement via un Intent ne pose aucun problème. Dès que j'hérite de la classe MapActivity, ca explose.

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
 
public class TestView extends MapActivity{
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.testview);
	}
 
	@Override
	protected boolean isRouteDisplayed() {
		// TODO Auto-generated method stub
		return false;
	}
}

Pourtant j'ai mis à jour mon fichier XML pour rendre en compte la clé de MapView :

Code:

1
2
3
4

<?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">
<TextView android:id="@+id/TextView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="MapView"></TextView>
 
<com.google.android.maps.MapView
                 android:layout_width="fill_parent"
                 android:layout_height="fill_parent"
                 android:apiKey="???????????????"
                 />
 
</LinearLayout>

Une idée ?

merci d'avance

Bonjour,
consulte ce topic: http://www.developpez.net/forums/d86...e-mapactivity/

Salut,
Peux tu mettre le contenu de ton fichier manifest?

As-tu ajouté cette ligne dans la balise application?
Code:

1 2 <uses-library android:name="com.google.android.maps"></uses-library>
Il te faudra aussi ça pour afficher une carte, juste avant </manifest>
Code:

1 2 3 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> <uses-permission android:name="android.permission.INTERNET"></uses-permission>

Je crois que ce

a suggeré c'est surement ça, soit tu as pas ajouté la librairie com.google.maps ou l'application qui s'etends de MapActivity dans manifest
