Question

我有RelativeLayout，我想在Window中显示。我是这样做的：

    static WindowManager wManager;    

    WindowManager.LayoutParams params = new WindowManager.LayoutParams(android.view.WindowManager.LayoutParams.FLAG_FULLSCREEN, android.view.WindowManager.LayoutParams.FLAG_FULLSCREEN, android.view.WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, android.view.WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN, PixelFormat.TRANSLUCENT);
                wManager = (WindowManager) activity_home.getSystemService(Context.WINDOW_SERVICE);
                LayoutInflater inflater = (LayoutInflater) activity_home.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                RelativeLayout view =  (RelativeLayout) inflater.inflate(R.layout.order_wait, null);
    wManager.addView(view, params);

但我只看到RelativeLayout的背景，并没有看到它的内容。

order_wait.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:text="Автомобиль будет через:"
                android:textColor="#000000"
                android:textSize="20sp"
                android:textStyle="bold" />
        </FrameLayout>

        <TextView

    </LinearLayout>

        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:background="#B6B6B6" >

        <Button
            android:id="@+id/bt_cancel"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_marginTop="4dp"
            android:layout_weight="1"
            android:background="@drawable/but_yellow"
            android:text="ОТМЕНА"
            android:textColor="#1e90ff"
            android:textSize="20dp" />
    </LinearLayout>

</RelativeLayout>

感谢您的回答。

对于inflater.inflate(R.layout.order_wait, null)，您可以尝试以root身份提供wManager而不是null吗？

WindowManager仅显示背景
