dialog-在固定時間後關閉對話框

在固定時間後關閉對話框

應用中包含一個對話框。

我想要在x秒後自動關閉這個對話框。前提是如果這段時間用戶對應用沒有任何操作。

類似彈出的音量拖動條（兩秒鐘用戶沒有操作就自動關閉）。

不知道怎麼實現？請高手指點，謝謝。

最佳回答：

// a dialog
final Dialog dialog = new Dialog(getApplicationContext());

// the code inside run() will be executed if .postDelayed() reaches its delay time
final Runnable runnable = new Runnable() {

    @Override
    public void run() {
        dialog.dismiss(); // hide dialog
    }
};

Button interaction = (Button) findViewById(R.id.bottom);

final Handler h = new Handler();

        // pressing the button is an "interaction" for example
interaction.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {


        h.removeCallbacks(runnable); // cancel the running action (the hiding process)
        h.postDelayed(runnable, 5000); // start a new hiding process that will trigger after 5 seconds
    }
});

追蹤用戶動作

@Override
public void onUserInteraction(){
    h.removeCallbacks(runnable); // cancel the running action (the hiding process)
    h.postDelayed(runnable, 5000); // start a new hiding process that will trigger after 5 seconds
}
