Android开发模仿qq视频通话悬浮按钮(实例代码)
模仿qq视频通话的悬浮按钮的实例代码，如下所示；
publicclassFloatingWindowServiceextendsService{
privatestaticfinalStringTAG="OnTouchListener";
privatestaticViewmView=null;
privatestaticWindowManagermWindowManager=null;
privatestaticContextmContext=null;
publicstaticBooleanisShown=false;

@Override
publicvoidonCreate(){
super.onCreate();
}
@Override
publicintonStartCommand(Intentintent,intflags,intstartId){
pixel=intent.getIntExtra("pixel",1);
showPopupWindow(this);
returnsuper.onStartCommand(intent,flags,startId);
}
/**

*@paramcontext

*/
privatevoidshowPopupWindow(finalContextcontext){
if(isShown){
return;
}
isShown=true;
//获取应用的Context
mContext=context.getApplicationContext();
//获取WindowManager
mWindowManager=(WindowManager)mContext.getSystemService(Context.WINDOW_SERVICE);
params=newWindowManager.LayoutParams();
mView=setUpView(context);
//类型
params.type=WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
intflags=WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;

}

//判断从按住到抬起时候的移动距离，如果如果移动距离大于20那么就拦截事件，否则就不拦截事件，主要是处理点击事件的冲突

@Nullable

Main
@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.open).setOnClickListener(this);

}
-点击开启关闭悬浮按钮
@Override
publicvoidonClick(Viewv){
switch(v.getId()){
caseR.id.open:
//判断是否拥有悬浮权限
//op的值是0~47，其中0代表粗略定位权限，1代表精确定位权限，24代表悬浮窗权限。（具体可以看看Android源码在android.app下就有个AppOpsManager类）
if(utils.checkOp(this,24)==0){
Intentintent=newIntent(MainActivity.this,FloatingWindowService.class);
intent.putExtra("pixel",utils.pixel(this)[0]);
startService(intent);
}else{
//引导用户进入悬浮权限设置界面
Intentintent=newIntent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:"+getPackageName()));
startActivityForResult(intent,200);
}
break;
caseR.id.close:
stopService(newIntent(MainActivity.this,FloatingWindowService.class));
break;
}
}
判断权限-获取屏幕的宽高
publicclassutils{
publicstaticintcheckOp(Contextcontext,intop){
finalintversion=Build.VERSION.SDK_INT;
if(version>=19){
Objectobject=context.getSystemService("appops");
Classc=object.getClass();

cArg[1]=int.class;
cArg[2]=String.class;
MethodlMethod=c.getDeclaredMethod("checkOp",cArg);
return(Integer)lMethod.invoke(object,op,Binder.getCallingUid(),context.getPackageName());
}catch(NoSuchMethodExceptione){
e.printStackTrace();
}catch(IllegalAccessExceptione){
e.printStackTrace();
}catch(IllegalArgumentExceptione){
e.printStackTrace();
}catch(InvocationTargetExceptione){
e.printStackTrace();
}
}
return-1;
}
/**
*获取屏幕的宽高
*@paramcontext
*@return
*/
publicstaticint[]pixel(Activitycontext){
DisplayMetricsdm=newDisplayMetrics();
context.getWindowManager().getDefaultDisplay().getMetrics(dm);
returnnewint[]{dm.widthPixels,dm.heightPixels};
}
}
--popupwindow填充布局文件
<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <LinearLayout android:id="@+id/popup_window" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@android:color/white" android:orientation="vertical"> <TextView android:background="@mipmap/ic_launcher" android:id="@+id/title" android:layout_width="50dp" android:layout_height="50dp"/> </LinearLayout> </LinearLayout>
