Android创建悬浮窗

简单的代码快速创建悬浮窗

WindowManager mWindowManager = (WindowManager) context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams mWindowParams = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_TOAST,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,//不接受事件及触摸
        PixelFormat.RGBA_8888);
if (Build.VERSION.SDK_INT < 19 ) {
    mWindowParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
}else{
    mWindowParams.type = WindowManager.LayoutParams.TYPE_TOAST;
}
mWindowManager.addView(new DesktopLayout(context),mWindowParams );

• DesktopLayout

  public class DesktopLayout extends LinearLayout {
      public DesktopLayout(Context context) {
          super(context);
          setOrientation(LinearLayout.VERTICAL);// 水平排列
          //设置宽高
          this.setLayoutParams( new LayoutParams(LayoutParams.WRAP_CONTENT,
                  LayoutParams.WRAP_CONTENT));
  
          View view = LayoutInflater.from(context).inflate(
                  R.layout.desklayout, null);
          this.addView(view);
      }
  }

• xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="100px"
    android:layout_height="100px"
    android:orientation="horizontal" >
    <TextView
        android:layout_width="100px"
        android:layout_height="100px"
