Android Wear类型检测 - 圆形或方形

Question

我很想知道磨损类型,无论是圆形还是方形,因为根据设备类型我想为圆形和方形制作不同的视图.从这篇文章我知道在SDK-20 android.view.View类中有一个新的侦听器来检测设备类型,使用这个我试图获取设备类型,但没有什么是在logcat上打印.以下是我试过的代码.

public class WearSplash extends Activity implements OnApplyWindowInsetsListener {
private WatchViewStub _stub = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_wear_splash);

    _stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
    _stub.setOnApplyWindowInsetsListener(this);
    _stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {

        @Override
        public void onLayoutInflated(WatchViewStub mStub) {
            // here on the basis of device type i want to inflate views.
        }
    });

}
@Override
public WindowInsets onApplyWindowInsets(View v, WindowInsets insets) {
    System.out.println(" in testing phase");
    if (insets.isRound())
        System.out.println("in round");
    else
        System.out.println("in square");
    return null;
  }
}

xml文件.

<?xml version="1.0" encoding="utf-8"?>
<android.support.wearable.view.WatchViewStub xmlns:android="http://schemas.android.com/apk/res/android"

回合:

<?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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.app.WearSplash"
tools:deviceIds="wear_round" >

<TextView
    android:id="@+id/text"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:contentDescription="@string/hello_world" />

</RelativeLayout>

广场:

<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.app.WearSplash"
tools:deviceIds="wear_square" >

<ImageView 
    android:id="@+id/image"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    android:contentDescription="@string/hello_world"
    android:background="@drawable/ic_launcher"/>

</LinearLayout>

我是新手,让我知道我哪里出错了.助手将受到高度赞赏.

Answer 1

API 23介绍:

isScreenRound()

Answer 2

非官方的方式(不使用WatchViewStub) - 但对我来说这更容易.https://github.com/tajchert/ShapeWear

只需复制ShapeWear.java类,并订阅屏幕形状检测事件setOnShapeChangeListener()或调用方法ShapeWear.isRound()(可以抛出错误,形状尚未确定)或ShapeWear. getShape()- 这可能导致ShapeWear.SHAPE_UNSURE相同的情况.
