这个悬浮窗是一个类似于微信通话的小屏视频框，利于Service开启和保持。悬浮是利用WindowManager实现

创建FloatingWindowService服务类

public class FloatingWindowService extends Service implements View.OnClickListener {

private WindowManager windowManager;

private WindowManager.LayoutParams layoutParams;

private View display;

private TextureView surfaceView;

private EasyPlayerClient client;

private boolean show=true;

private int qiehuan=0;

private long startTime=0;

private long endTime=0;

private boolean isclick=false;

public FloatingWindowService() {

}

@Override

public void onCreate() {

super.onCreate();

windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

layoutParams = new WindowManager.LayoutParams();

// 设置图片格式，效果为背景透明

layoutParams.format = PixelFormat.RGB_565;

Log.i("悬浮窗", "Build.VERSION.SDK_INT" + Build.VERSION.SDK_INT);

if (Build.VERSION.SDK_INT > Build.VERSION_CODES.O) {

// android 8.0及以后使用

layoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;

} else {

// android 8.0以前使用

layoutParams.type = WindowManager.LayoutParams.TYPE_PHONE;

}

layoutParams.gravity = Gravity.LEFT | Gravity.TOP;

//该flags描述的是窗口的模式，是否可以触摸，可以聚焦等

layoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;

// 设置视频的播放窗口大小

layoutParams.width = 400;

layoutParams.height = 550;

layoutParams.x = 700;

layoutParams.y = 0;

}

@Override

public int onStartCommand(Intent intent, int flags, int startId) {

if (show) {

showFloatingWindow();

}

return super.onStartCommand(intent, flags, startId);

}

@Override

public IBinder onBind(Intent intent) {

// TODO: Return the communication channel to the service.

return null;

}

@SuppressLint("NewApi")

private void showFloatingWindow(){

if (Settings.canDrawOverlays(this)) {

LayoutInflater layoutInflater = LayoutInflater.from(this);

display = layoutInflater.inflate(R.layout.little, null);

surfaceView = display.findViewById(R.id.texture_view);

client = new EasyPlayerClient(this, BuildConfig.KEY, surfaceView, null, null);

final EditText et = new EditText(this);

et.setHint("请输入RTMP地址");

final SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);

et.setText(sp.getString("url", "rtmp://111.198.38.150:10085/live/869496039536917_0001"));

client.play("rtmp://111.198.38.150:10085/live/869496039536917_0001");

windowManager.addView(display, layoutParams);

display.setOnTouchListener(new FloatingOnTouchListener());

display.setOnClickListener(new FloatingOnClickListener());

show=false;

}

}

@Override

public void onClick(View v) {

}

//点击事件

private class FloatingOnClickListener implements View.OnClickListener{

@Override

public void onClick(View v) {

if (qiehuan % 2 == 0) {

MainActivity.qiehuan();

client.stop();

client.play("rtmp://111.198.38.150:10085/live/863065035752780_0001");

} else {

MainActivity.qiehuan();

client.stop();

client.play("rtmp://111.198.38.150:10085/live/869496039536917_0001");

}

qiehuan++;

}

}

// touch移动视频窗口 | 事件拦截

private class FloatingOnTouchListener implements View.OnTouchListener {

private int x;

private int y;

@Override

public boolean onTouch(View view, MotionEvent event) {

switch (event.getAction()) {

case MotionEvent.ACTION_DOWN:

x = (int) event.getRawX();

y = (int) event.getRawY();

isclick = false;//当按下的时候设置isclick为false

startTime = System.currentTimeMillis();

break;

case MotionEvent.ACTION_MOVE:

isclick = true;//当按钮被移动的时候设置isclick为true

int nowX = (int) event.getRawX();

int nowY = (int) event.getRawY();

int movedX = nowX - x;

int movedY = nowY - y;

Log.d("悬浮窗", "movedX = " + movedX + ", movedY =" + movedY);

x = nowX;

y = nowY;

layoutParams.x = layoutParams.x + movedX;

layoutParams.y = layoutParams.y + movedY;

windowManager.updateViewLayout(view, layoutParams);

break;

case MotionEvent.ACTION_UP:

endTime = System.currentTimeMillis();

//当从点击到弹起小于半秒的时候,则判断为点击,如果超过则不响应点击事件

if ((endTime - startTime) > 0.1 * 1000L) {

isclick = true;

Log.e("tag","拖动");

} else {

isclick = false;

Log.e("tag","点击");

}

System.out.println("执行顺序up");

break;

}

return isclick;

}

}

@Override

public void onDestroy() {

// 移除浮动框

if (windowManager != null) {

windowManager.removeView(display);

}

super.onDestroy();

}

}

别忘了在AndroidManifest.xml调用服务

Activity里开启服务(仅展示重要部分)

//判断是否授权及开启服务

@RequiresApi(api = Build.VERSION_CODES.M)

public void startFloatingService() {

if (ActivityUtil.isServiceWork(this, "com.demon.suspensionbox.FloatingService")) {//防止重复启动

Toast.makeText(this, "已启动！", Toast.LENGTH_SHORT).show();

return;

}

if (!Settings.canDrawOverlays(this)) {

Toast.makeText(this, "当前无权限，请授权", Toast.LENGTH_SHORT).show();

startActivityForResult(new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName())), 0);

} else {

if (istui)

startService(new Intent(MainActivity.this, FloatingWindowService.class));

}

}

@SuppressLint("NewApi")

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

// 判断获取权限是否成功

if (requestCode == 0) {

if (!Settings.canDrawOverlays(this)) {

Toast.makeText(this, "授权失败", Toast.LENGTH_SHORT).show();

} else {

Toast.makeText(this, "授权成功", Toast.LENGTH_SHORT).show();

startService(new Intent(MainActivity.this, FloatingWindowService.class));

}

}

}

//关闭服务

@Override

public void onDestroy() {

stopService(new Intent(MainActivity.this, FloatingWindowService.class));

super.onDestroy();

}

至此，就实现了一个很biu特否的视频悬浮框，更多功能还在筹备中，敬请期待
