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
