How Can I Send Key Events In Android?

I am macking a custom navigation bar to Android 4.0.3.r1 and want to send key events like 'Home' and 'Back'. My application is not a system therefore: IWindowManager mWindowManager

Solution 1:

Here are some precision to Roman answer

BaseInputConnectionmInputConnection=newBaseInputConnection( findViewById(R.id.main_content), true);
KeyEventkd=newKeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MENU);
KeyEventku=newKeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MENU);
mInputConnection.sendKeyEvent(kd);
mInputConnection.sendKeyEvent(ku);

Solution 2:

BaseInputConnectionmInputConnection=newBaseInputConnection(targetView, true);
mInputConnection.sendKeyEvent(newKeyEvent(...));

Solution 3:

It works for me：

publicstaticvoidsimulateKey(finalint KeyCode) {

    newThread() {
        @Overridepublicvoidrun() {
            try {
                Instrumentationinst=newInstrumentation();
                inst.sendKeyDownUpSync(KeyCode);
            } catch (Exception e) {
                Log.e("Exception when sendKeyDownUpSync", e.toString());
            }
        }

    }.start();
}

Solution 4:

you can try this

try
{
    StringkeyCommand="input keyevent " + KeyEvent.KEYCODE_MENU;
    Runtimeruntime= Runtime.getRuntime();
    Processproc= runtime.exec(keyCommand);
}
catch (IOException e)
{
    // TODO Auto-generated catch block
    e.printStackTrace();
}

of course, you can choose command input text ... for input a text.

Solution 5:

None of these are valid. To go to Home screen from use below code.

Intenthome=newIntent(Intent.ACTION_MAIN);
home.addCategory(Intent.CATEGORY_HOME);
//home.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(home);

If you are not calling from activity/fragment you may have to uncomment the flag part. For going back below code works on some devices.

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

Let me know if this helps!
