如何在 android 中使用长按和录音

How to use Long press and record sound in android

在我的应用程序中,我需要使用单击并长按按钮

点击某些东西(调用 Itemclick())并长按录制声音

并使用此代码:

 send.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch(event.getAction()){
            case MotionEvent.ACTION_DOWN:
            {
                recording =false;
                t=new Timer();
                t.scheduleAtFixedRate(new TimerTask() {

                    @Override
                    public void run() {
                        runOnUiThread(new Runnable() {

                            @Override
                            public void run() {
                                if(count>=2)
                                    t.cancel();
                                    count++;

                            }
                        });
                    }
                }, 1, 1000);
                break;
            }    
            case MotionEvent.ACTION_MOVE:
            {
                if(count >=2&&!recording)
                {

                     recording=true;
                     count=0;
                     Rec=new Recorder();
                     Rec.startRecord();
                }
                break;

            }
            case MotionEvent.ACTION_UP:
            { 
                t.cancel();
                if(!recording)
                {
                    count=0;
                    Itemclick();
                    break;
                }
                recording=false;
                Rec.StopRecord();
                db.open();
                db.insert_offline(Rec.getName(), true, false);
                listItems.add(Rec.getName());
                type.add("v");
                adapter.notifyDataSetChanged();
                db.close();
                Rec=null;
                break;
            }
           }
            return false;
        }
    });

在此代码中,我使用计时器来查找长按,但我想要一种更简单、更快速的方法来执行此操作。

您有什么想法或更好的解决方案吗?

您或许可以替换计时器并使用 android 的内置事件侦听器进行点击和按住事件:

View.OnLongClickListener
View.OnClickListener

按照这条路线,您的代码将如下所示。

send.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //code for click event
    }
});

send.setOnLongClickListener(new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {
        //code for hold event... which sounds like you want to begin recording here
        return true; //indicate we're done listening to this touch listener
    }
});

send.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch(event.getAction()){
            case MotionEvent.ACTION_UP:
            { 
            //stop recording voice if a long hold was detected and a recording started
            return true; //indicate we're done listening to this touch listener
            }
        }
        return false;
    }
});
