我有一个包含两个活动的程序。我从第一个活动转到第二个活动。然后按返回键，程序有延迟并显示白屏。如何消除延迟？当我点击我的按钮时，在第一个活动中执行此操作
myHandler.postDelayed(new Runnable() {
@Override
public void run() {
Animation vanish2 =AnimationUtils.loadAnimation(MainActivity.this,R.anim.out_to_right);
findViewById(R.id.imageView1).startAnimation(vanish2);
findViewById(R.id.textView1).startAnimation(vanish2);
vanish2.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation arg0) {
}
@Override
public void onAnimationRepeat(Animation arg0) {
//startActivity(new Intent(MainActivity.this,S1.class));
}
@Override
public void onAnimationEnd(Animation arg0) {
t1.setVisibility(View.INVISIBLE);
i1.setVisibility(View.INVISIBLE);
startActivity(new Intent(MainActivity.this,S1.class));
//overridePendingTransition(R.anim.fadeout, R.anim.fadein);
//overridePendingTransition(R.anim.push_down_in, R.anim.push_down_out);
}
});
}
}, 400);
第二个活动什么都没有，我只想按后退按钮并退出第二个活动
这是我的第一个活动。顺便说一句，我是 android 的初学者
