Android déclencheur par programmation longue presse HOME

Question

J'essaie de trouver un moyen de simuler l'action d'une longue pression sur le bouton HOME. Je le bouton BACK travailler avec le code suivant:

this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK)); this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));

Mais lorsque je tente d'imiter un (long) presse HOME même:

this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HOME)); 
// Thread.sleep(1000); Perhaps for long press? 
this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HOME)); 

Rien ne se passe. Y a-t-il un autre moyen d'imiter le bouton ACCUEIL?

Merci d'avance pour toute aide. Andrew

Answer 1

Vous pouvez essayer ceci:

this.dispatchKeyEvent(new KeyEvent((long) ViewConfiguration.getLongPressTimeout(), (long) 0, KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HOME), 0); // ViewConfiguration.getLongPressTimeout() returns the duration in milliseconds before a press turns into a long press 

Il utilise ce constructeur:

/** 
* Create a new key event. 
* 
* @param downTime The time (in {@link android.os.SystemClock#uptimeMillis}) 
* at which this key code originally went down. 
* @param eventTime The time (in {@link android.os.SystemClock#uptimeMillis}) 
* at which this event happened. 
* @param action Action code: either {@link #ACTION_DOWN}, 
* {@link #ACTION_UP}, or {@link #ACTION_MULTIPLE}. 
* @param code The key code. 
* @param repeat A repeat count for down events (> 0 if this is after the 
* initial down) or event count for multiple events. 
*/ 
public KeyEvent(long downTime, long eventTime, int action, 
       int code, int repeat) { 
    mDownTime = downTime; 
    mEventTime = eventTime; 
    mAction = action; 
    mKeyCode = code; 
    mRepeatCount = repeat; 
    mDeviceId = KeyCharacterMap.VIRTUAL_KEYBOARD; 
} 

Voir this. Cela pourrait aider.
