导读：public class MyApp extends Application { private String myState; public String getState() { return myState; } public void setState(String s) { myState = s; } } public cl......
public class MyApp extends Application {
private String myState;
public String getState() {
return myState;
}
public void setState(String s) {
myState = s;
}
}
public class Blah extends Activity {
@Override
public void onCreate(Bundle b){
...
MyApp appState = ((MyApp)getApplicationContext());
String state = appState.getState();
...
}
}
然后再manifest中添加应用：
<application android:name=".MyApp" android:icon="@drawable/icon"
android:label="@string/app_name">
<activity android:name=".ClickableListItemActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
