How do you send a long print with InstrumentationTestCase?

Question

In Android, how can I send a long press with InstrumentationTestCase? I would like to do, for example sendKeys(KEYCODE_DPAD_CENTER), but do it with a long click.

Answer 1

I don't know if this is the only / correct way, but I managed to do it as follows:

public void longClickDpadCenter() throws Exception {
    getInstrumentation().sendKeySync(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_CENTER));
    Thread.sleep(ViewConfiguration.get(mContext).getLongPressTimeout());
    getInstrumentation().sendKeySync(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_DPAD_CENTER));
}

Answer 2

You can try using the helper method below:

private void longPress(int key) {
    long downTime = SystemClock.uptimeMillis();
    long eventTime = SystemClock.uptimeMillis();
    KeyEvent event1 = new KeyEvent(downTime, eventTime, KeyEvent.ACTION_DOWN, key, 0);
    KeyEvent event2 = new KeyEvent(downTime, eventTime, KeyEvent.ACTION_DOWN, key, 1);
    getInstrumentation().sendKeySync(event1);
    getInstrumentation().sendKeySync(event2);
}

And an example of use:

longPress(KeyEvent.KEYCODE_ENTER);
