Android: Presenting A Notification During A Call?
Solution 1:
You need a BroadcastReceiver like that:
publicclassIncomingBroadcastReceiverextendsBroadcastReceiver {
@OverridepublicvoidonReceive(Context context, Intent intent) {
MyLog.d("IncomingBroadcastReceiver: onReceive: ");
Stringstate= intent.getStringExtra(TelephonyManager.EXTRA_STATE);
MyLog.d("IncomingBroadcastReceiver: onReceive: " + state);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
Intenti=newIntent(context, IncomingCallActivity.class);
i.putExtras(intent);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
}
And register it in the manifest to <action android:name="android.intent.action.PHONE_STATE"></action>
.
Then create an Activity like that:
publicclassIncomingCallActivityextendsActivity {
@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
MyLog.d("IncomingCallActivity: onCreate: ");
// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
setContentView(R.layout.main);
Stringnumber = getIntent().getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
TextView text = (TextView)findViewById(R.id.text);
text.setText("Incoming call from " + number);
}
}
which has this layout:
<?xml version="1.0" encoding="utf-8"?><TextViewxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/text"android:layout_width="match_parent"android:layout_height="match_parent"android:gravity="center_vertical|center_horizontal"android:text="text"android:windowBackground="@android:color/transparent"android:windowIsTranslucent="true"android:windowAnimationStyle="@android:style/Animation.Translucent"></TextView>
This will produce a translucent dialog-like activity on top of the incoming call screen, that allows the user to answer the call (doesn't interfere with touch events).
Solution 2:
Up to Android 2.3 you can not override the calling screen, but you can show a Toast message on it. The longest period of a toast is 3 seconds and after that it will dissapear. You can however create a thread that calls show() method of the toast every 2 seconds. Something like that:
Thread t = new Thread() {
publicvoidrun() {
try {
while (true) {
if( isInCall ){
toast.cancel();
break;
}
toast.show();
sleep(1850);
}
} catch (Exception e) {
Log.d("Exception: " + e.toString());
}
}
};
t.start();
You have to declare toast:
private Toast toast;
You have to init the toast object befor showing it.
toast = newToast(getBaseContext());
LayoutInflaterinflater= (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Viewlayout= inflater.inflate(R.layout.toast, null, false);
toast.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
