一、悬浮窗点击后的界面:
主要有四个功能,返回、应用程序、退出和主界面。其他功能也可以类似添加。
界面布局代码就不贴出来了,源码(切记需要签名才能让功能实现):下载地址
二、主要是检测系统启动或者app启动的时候出现悬浮窗,并且只有当检测到前台运行了特定程序才会隐藏图标。
<receiver android:name="com.bumblebee.remindeasy.StartupReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service android:name="com.bumblebee.remindeasy.service.AuxiliaryService" />
添加检测BOOT_COMPLETED,需要添加权限,
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
三、开始写service,调用自定义的view。
public void onCreate() {
super.onCreate();
new EasyTouchView(this, this).initTouchViewEvent();
}
四、自定义view的实现,主要是touchview的显示,以及移动操作和点击事件注册。
public EasyTouchView(Context context, ServiceListener listener) {
super(context);
mContext = context;
mSerLisrener = listener;
mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
if (msg.what == 100) {
if (isCellaretteAppforeground(mContext)) {//检测到“com.xxx.xxx“程序,将隐藏touchview
mTouchView.setVisibility(View.INVISIBLE);
} else {
mTouchView.setVisibility(View.VISIBLE);//否则显示touchview
}
this.sendEmptyMessageDelayed(100, 500);
}
}
};
}
/*
* 检测是否存在某个应用com.xxx.xxx在前台运行。
*/

ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> appProcesses = am.getRunningAppProcesses();
