Hi,
I am trying to dispatch key-event to other activity from a dialog, I
am trying to add a dialog in WindowManagerSerivce.java file in
frameworks/base/services/java/com/android/server, to display this
dialog i am using the following snippet to get SystemContext
ActivityThread at = ActivityThread.currentActivityThread();
if (at == null) {
Looper.prepare();
at = ActivityThread.systemMain();
}
if(at != null){
sysContext = at.getSystemContext();
Log.d(TAG, "SystemContext = " + sysContext);
}
Dialog dialog = new Dialog(sysContext);
dialog.setContentView(com.android.internal.R.layout.<my_Custom_layout>);
dialog.setTitle("Custom Dialog");
dialog.show();
but i can't able to display the dialog
When i tried to launch activity as a dialog (@android:style/
Theme.Dialog) using intent, for the same, activity is displayed as
dialog. fine, now what i am trying is i want to dispatch keyevent when
you press a button in the dialog displayed, i am using handler to pass
the messages to WindowManagerService, where it will dispatch the
keyevent and even i get the pid of top activity and pass the same to
dispatchKey() method in WindowManagerService.java, dispatchKey
returns '1' which means the key is dispatched successfully. what
actually i am doing is when you press a button in the dialog, i will
pass a message to handler implemented in WindowManagerService.java
say, DISPATCH_BACK_KEY, and i am able to get proper PID from the
activity manager
packageName =
am.getRunningTasks(1).get(0).topActivity.getPackageName();
List<ActivityManager.RunningAppProcessInfo> processes;
processes = am.getRunningAppProcesses();
for(ActivityManager.RunningAppProcessInfo info:
processes) {
Log.i("Process:", info.processName);
if(currentPackageName.equalsIgnoreCase(info.processName)){
Log.i(TAG, "Found !");
mpid = info.pid; //pid of top Activity
muid = 0;
}
}
public void handleMessage(Message msg) {
switch (msg.what) {
case DISPATCH_BACK_KEY:
Log.d(TAG, "Dispatching Back_Key");
code = KeyEvent.KEYCODE_BACK;
KeyEvent backEvent = new KeyEvent(downTime, eventTime, action, code,
repeatCount, metaState,
deviceId, scancode, KeyEvent.FLAG_FROM_SYSTEM);
Log.i(TAG, "PID = " + mpid + ", UID = " +muid);
result = dispatchKey(backEvent, mpid, muid);
Log.d(TAG, "Dispatch Key Returns = " + result);
break;
}
Key is dispatched successfully, but the activity beyond the my-dialog
displayed is still visible. please help me how can i proceed to
dispatch back key to the activity beyond my-dialog..
Thanks in advance
