如何从仪器测试用例发送长新闻?

不知道这是不是唯一/正确的方法,但我设法做到了:

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));
}

您可以尝试下面的helper方法:

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);
}

使用示例:

longPress(KeyEvent.KEYCODE_ENTER);
