Question

嗨，我正在制作一个应用程序，我基本上我有两个活动。在第一个活动中，我有一个textview和imageview，在imageview中我已经设置了一个图层列表作为背景，同样适用于第二个活动。现在我的问题是，当我在第一个活动中应用共享元素过渡动画时，textview和imageview都是动画的，但第二个活动中的layerlist会丢失它的形状，你可以看到下面的图像。

和

现在有动画的屏幕

现在从上面的图片中你很容易看到我使用动画时的差异，第二个屏幕中的图像失去了我在互联网上搜索的形状，但没有得到任何正确的解决方案所以如果有人可以帮助我在这里请。

我的第一个activity.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_simple_one"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".newactivities.NewActivity"
    android:background="@color/colorPrimary">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Login"
        android:id="@+id/login_text"
        android:transitionName="login_text"
        android:textSize="25sp"
        android:textColor="@color/White"
        android:layout_marginTop="215dp"/>
    <ImageView
        android:id="@+id/simple_activity_a_imageView"
        android:layout_width="150dp"
        android:layout_height="150dp"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="80dp"
        android:scaleType="centerCrop"
        android:src="@drawable/login_page_curve"
        android:contentDescription="@string/lion"
        android:transitionName="@string/simple_activity_transition"
        tools:ignore="UnusedAttribute" />

    <Button
        android:id="@+id/simple_activity_a_btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:visibility="gone"
        android:layout_marginBottom="19dp"
        android:text="@string/lion" />
</RelativeLayout>

My First Activity.java

public class NewActivity extends AppCompatActivity {

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_new);
       // getWindow().setEnterTransition(null);
        //getWindow().setExitTransition(null);
        final ImageView imageView = (ImageView) findViewById(R.id.simple_activity_a_imageView);
        final TextView textView = (TextView)findViewById(R.id.login_text);
        Button button = (Button) findViewById(R.id.simple_activity_a_btn);
        imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(NewActivity.this, New2Activity.class);
                Pair[] pairs  = new Pair[2];
                pairs[0] = new Pair<View,String>(imageView,
                        ViewCompat.getTransitionName(imageView));
                pairs[1] = new Pair<View,String>(textView,ViewCompat.getTransitionName(textView));
                //pairs[2] = new Pair<View,String>(register_text,getResources().getString(R.string.register_text_transition));
                ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation
                        (NewActivity.this,pairs);
                startActivity(intent,optionsCompat.toBundle());


            }
        });
    }

    public void gotoregister(View view) {
    }
}

我的layerlist xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle"/>
    </item>
    <item
        android:bottom="-880dp"
        android:left="-280dp"
        android:right="-280dp"
        android:top="0dp">
        <shape android:shape="oval">
            <solid android:color="@color/White" />
        </shape>
    </item>
</layer-list>

和我的第二个layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_simple_two"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".newactivities.New2Activity"
    android:background="@color/colorPrimary">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        >
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true">
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Or Login"
        android:textSize="30sp"
        android:transitionName="login_text"
        android:textColor="@color/White"
        />
        </LinearLayout>
    </RelativeLayout>
    <ImageView
        android:layout_marginTop="80dp"
        android:id="@+id/simple_activity_b_image"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"
        android:adjustViewBounds="true"
        android:src="@drawable/login_page_curve"
        android:contentDescription="lion"
        android:transitionName="@string/simple_activity_transition"
        tools:ignore="UnusedAttribute" />



</LinearLayout>

应用动画后，图层列表会在第二个活动中丢失其形状
