Android - 如何在按下默认后退按钮时为活动过渡设置动画 [英] Android - How to animate an activity transition when the default back button is pressed

问题描述

在我的活动中，我有一个带有以下点击侦听器的按钮，效果很好:

In my activity, I have a button with the following click listener that is working great:

final ImageButton startOverButton = (ImageButton) findViewById(R.id.start_over_button);
startOverButton.setOnClickListener(new View.OnClickListener(){

    @Override
    public void onClick(final View v) {

        finish();//go back to the previous Activity
        overridePendingTransition(R.anim.comming_in, R.anim.comming_out);
    }
});

它以我想要的方式动画返回上一个活动.但是，当用户按下 Android 默认的后退按钮时，不会触发动画.我的问题是:我应该把动画代码放在哪里 overridePendingTransition(R.anim.comming_in, R.anim.comming_out); 以便当用户点击我的按钮和输入时触发这个动画默认的 Android 后退按钮?

It animates the return to the previous activity the way I want. However, when the user presses the Android default back button, the animation is not triggered. My question is: where should I put the animation code overridePendingTransition(R.anim.comming_in, R.anim.comming_out); so that this animation will be triggered both when the user clicks on my button and in the default Android back button?

作为一个天真的尝试，我尝试将 overridePendingTransition(R.anim.comming_in, R.anim.comming_out); 代码行放在 onDestroy() 方法，但没有用.

As a naive try, I have tried to put the overridePendingTransition(R.anim.comming_in, R.anim.comming_out); line of code in the onDestroy() method but it did not work.

先谢谢你！

推荐答案

也许你可以在 Activity 中的 onBackPressed() 方法中完成这项工作.

maybe you can do this work in onBackPressed() method in the activity.

@Override
public void onBackPressed() {
    super.onBackPressed();
    overridePendingTransition(R.anim.comming_in, R.anim.comming_out);   
}
