我在Android Wear项目中实现了onApplyWindowInsets回调。在该方法中,它调用isRound()来确定代码是否在圆形或矩形Wear Smart智能手表上运行。从圆形磨损仿真器调用此回调。 (虽然isRound()返回false,这是错误的。)但问题是onApplyWindowInsets回调永远不会从我的Samsung Gear Live调用。因此,如果从onApplyWindowInsets中膨胀视图,则视图不会膨胀。有没有人得到应用程序窗口设置来触发真实设备?似乎无法保证。如果是这样,那么如何根据屏幕类型膨胀不同的视图?

在您的布局中,您可以设置特定的" sub"圆形/矩形屏幕的布局:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.wearable.view.WatchViewStub
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/stub"
app:rectLayout="@layout/rect_layout"
app:roundLayout="@layout/round_layout"/>
</FrameLayout>
如果你对rect_layout和round_layout使用不同的id,你可以在onCreate上检查它,如下所示:
@Override
public void onCreate(Bundle b) {
super.onCreate(b);
setContentView(R.layout.main_activity);
WatchViewStub stub = (WatchViewStub) findViewById(R.id.stub);
stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
@Override
public void onLayoutInflated(WatchViewStub stub) {
mRectBackground = (RelativeLayout) findViewById(R.id.rect_layout);
mRoundBackground = (RelativeLayout) findViewById(R.id.round_layout);
}
});
}
mRectBackground或mRoundBackground都将为非null,而不是两者。文档:https://developer.android.com/training/wearables/apps/layouts.html#UiLibrary
其他人尝试使用setOnApplyWindowInsetsListener的策略,如下所示:https://github.com/xamarin/monodroid-samples/blob/master/wear/GridViewPager/GridViewPager/MainActivity.cs。它对我不起作用。

onApplyWindowInsets
实际上要求开发人员在侦听器中调用WatchViewStub
的{{1}}方法。例如:
onApplyWindowInsets
虽然初看起来可能不太直观,但如果用户选择,这允许开发人员覆盖默认的WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
stub.setOnApplyWindowInsetsListener(new View.OnApplyWindowInsetsListener() {
@Override
public WindowInsets onApplyWindowInsets(View view, WindowInsets windowInsets) {
//////////////////////////////////////////////////
// IMPORTANT - the following line is required
stub.onApplyWindowInsets(windowInsets);
// Set the instance variable to say whether this is round...
mIsRound = windowInsets.isRound();
return windowInsets;
}
});
实现。
onApplyWindowInsets
的文档声明:“侦听器可以可选调用参数View的onApplyWindowInsets方法,以将View的正常行为应用为其自身的一部分。”

谢谢你!你聪明的技术似乎解决了这个问题。 (我说“似乎”,因为在将mRoundBackground设置为非空值的实际圆形设备上测试代码之前,我肯定不会确定。)
现在有三个Android Wear形状(rect / square,round w / chin和full round),我添加了两个全局值来查找屏幕形状,然后按如下方式修改回调:
stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
@Override
public void onLayoutInflated(WatchViewStub stub) {
//mRectBackground = (RelativeLayout) findViewById(R.id.LinearLayout1);
mRoundBackground = (RelativeLayout) findViewById(R.id.LinearLayout2);
if (mRoundBackground != null) round = true;
else round = false;
WindowManager window = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
Display display = window.getDefaultDisplay();
//Added android.graphics.Point to imports for this next section
Point point = new Point (0,0);
display.getSize(point);
scrnHeight = point.y;
scrnWidth = point.x;
if (round && scrnWidth == scrnHeight) chin = false;
else chin = true;
//round = true; //For testing on the emulator!!!!!!
}
});
有没有人知道在Moto360上检测下巴的更好方法?
更新:刚刚在Moto 360上运行此代码并且此技术未检测到圆形屏幕。所以现在我只是检测高度是否等于宽度。但是,当更多Android Wear设备出现时,这对于未来来说是一种糟糕的技术。所以问题仍然存在,如何确定那些真正的Android Wear设备上的圆形屏幕?

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,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()
- 哪个可以导致ShapeWear.SHAPE_UNSURE
处于同样的情况。
