在API&gt; = 21上,您可以直接使用CustomViewOutlineProvider
CustomViewOutlineProvider.java
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public class CustomViewOutlineProvider extends ViewOutlineProvider {
int roundCorner;
public CustomViewOutlineProvider(int round) {
roundCorner = round;
}
@Override
public void getOutline(View view, Outline outline) {
outline.setRoundRect(0, 0, view.getWidth(), view.getHeight(), roundCorner);
}
}
活动
TextView textView = (TextView) findViewById(R.id.shadow_txt);
textView.setOutlineProvider(new CustomViewOutlineProvider(30));
textView.setClipToOutline(true);
对于Prelollipop设备(API&lt; 21)
<TextView
android:background="@drawable/btn_with_shadow"
android:gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Font Style"
android:textColor="@color/white"
android:paddingRight="24dp"
android:paddingLeft="24dp"
android:paddingTop="12dp"
android:paddingBottom="12dp"
/>
btn_with_shadow.xml
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/btn_shadow"/>
<item
android:drawable="@drawable/bg_button"
android:bottom="4px"
android:top="3px"
android:right="4px"
android:left="3px"/>
</layer-list>

<corners android:radius="20dip"/>
</shape>
bg_button.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@color/colorPrimary"/>
<corners android:radius="20dp" />
</shape>
colors.xml
