android实现handler回传

//激活VideoActivity中的handler
VideoActivity.handler = new Handler(msg -> {
    Object obj = msg.obj;
    String s = obj.toString();
    Log.i("weicy",s+",,v,");
    return  false;
});



//将值返回
//定义handler
public static Handler handler ;

Message msg = Message.obtain();
msg.obj=srcPath;
if (handler!=null){
    handler.sendMessage(msg);
}
