Question

我在进入或退出活动时使用动画,进入活动动画工作正常,但退出动画效果不佳.当我按下后退按钮时,我开始退出动画.发生的事情是它首先开始输入当前活动的动画然后显示最后一个活动我想要一个简单的退出动画按下后退按钮.

Slide_out.xml

    <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromXDelta="0%p"
    android:toXDelta="-100%p" >

</translate>

Slide_in.xml

    <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromXDelta="100%p"
    android:toXDelta="0%p" >

</translate>

按下操作栏后退按钮

public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub
    switch (item.getItemId()) {
    case R.id.home:

        finish();
        overridePendingTransition(R.anim.slide_out, R.anim.slide_in);
        return true;


    default:
        break;
    }

    return super.onOptionsItemSelected(item);

}

Answer 1

首先在anim文件夹中再创建一个动画,即nothing.xml

nothing.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromXDelta="0%"
    android:toXDelta="0%" >

</translate>

这是你的slide_in.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromXDelta="-100%"
    android:toXDelta="0%" >

</translate>

和slide_out.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromXDelta="0%"
    android:toXDelta="100%" >

</translate>

现在像这样调用你的NewActivity

startActivity(new Intent(CurrentActivity.this, NewActivity.class));
overridePendingTransition(R.anim.slide_in, R.anim.nothing);

然后在你的后退按钮上单击执行此操作

finish();
overridePendingTransition(R.anim.nothing, R.anim.slide_out);

我使用了slide_in.xml

    <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromXDelta="100%"
    android:toXDelta="0%" >

</translate>

slide_out.xml

    <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromXDelta="0%"
    android:toXDelta="-100%" >

</translate>

slide_enter.xml

  <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromXDelta="-100%"
    android:toXDelta="0%" >

</translate>

slide_exit.xml

    <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromXDelta="0%"
    android:toXDelta="100%" >

</translate>

码

        Intent i=new Intent(Authentication.this,Login.class);
        startActivity(i);
        overridePendingTransition(R.anim.slide_in, R.anim.slide_out);

以前

         finish();
         overridePendingTransition(R.anim.slide_enter, R.anim.slide_exit);

Answer 3

添加动画onBackPressed，点击后退按钮时会显示动画。

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