java - ActionBar 向上按钮过渡效果

Question

当按下后退按钮时更改活动时，我已经创建了一个动画方法。问题是操作栏向上按钮具有到前一个活动的默认过渡效果，我找不到覆盖该动画并使用新动画的方法。有任何想法吗？提前致谢

最好这将在java中进行硬编码

Answer 1

只需获得“回家”活动

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    if (item.getItemId() == android.R.id.home) {
        finish();
        overridePendingTransition(R.animator.anim_left, R.animator.anim_right);
        return true;
    }
    return false;
}

Answer 2

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            onBackPressed();
            return true;

        default:
            return super.onOptionsItemSelected(item);
    }
}

@Override
public void onBackPressed() {
    this.finish();
    overridePendingTransition(R.anim.fade_in, R.anim.right_slide_out);
}

fade_in.xml ( R.anim.fade_in )

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromAlpha="0.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="1.0" />

right_slide_out.xml ( R.anim.right_slide_out )

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_decelerate_interpolator">
    <translate
        android:duration="200"
        android:fromXDelta="0"
        android:toXDelta="100%p" />
</set>
