Simulate Android button click programmatically
提问by EGHDK
I've seen thisroute,
我见过这条路，
View.performClick();
but it doesn't show the actual press of the button. I've also tried thismethod,
但它没有显示按钮的实际按下。这个方法我也试过
btn.setPressed(true);
btn.invalidate();
but, it just shows the button being pressed down. I've narrowed it down to this code, which presses down, and releases, but doesn't click. Am I missing something? How can I do a complete click as if though the user was clicking (monkeyrunner is not an option as of right now)
但是，它只显示按钮被按下。我把它缩小到这个代码，它按下并释放，但不点击。我错过了什么吗？我如何进行完整的点击，就好像用户正在点击一样（monkeyrunner 目前不是一个选项）
btn = (Button) findViewById(R.id.btn_box);
Handler handler = new Handler();
Runnable r = new Runnable() {
public void run() {
btn.setPressed(true);
btn.invalidate();
Handler handler1 = new Handler();
Runnable r1 = new Runnable() {
public void run() {
btn.setPressed(false);
btn.invalidate();
}
};
handler1.postDelayed(r1, 1000);
}
};
handler.postDelayed(r, 1000);

Your code is fine. just add btn.performClick();after the invalidate();
你的代码没问题。只需在btn.performClick();之后添加 invalidate();
And for better look you can reduce the time of handler1.
为了更好看，您可以减少handler1.
