在安卓系统中防止双击按钮的最佳方法是什么?


当前回答

更可取的解决方案是,

onclick(){
  btn.setEnabled(false);
  btn.setClickable(false);
  //yourwork
  myWork();
}

myWork(){
 //your tasks.
 btn.setEnabled(true);
 btn.setClickable(true);
}

由于一个环节很容易被忽略,我不得不一遍又一遍地重复这个环节

在点击的时候保存最后一次点击的时间可以避免这个问题。

i.e.

private long mLastClickTime = 0;

...

// inside onCreate or so:

findViewById(R.id.button).setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        // mis-clicking prevention, using threshold of 1000 ms
        if (SystemClock.elapsedRealtime() - mLastClickTime < 1000){
            return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();

        // do your magic here
    }
}

我希望这能帮助你,把代码放在你的事件处理程序。

// --------------------------------------------------------------------------------

    boolean hasTag = null != which.getTag( R.id.preventing_double_click_tag );

    if ( hasTag ) {
        // Do not handle again...
        return;
    } else {
        which.setTag( R.id.action, Boolean.TRUE );

        which.postDelayed( new Runnable() {
            @Override
            public void run() {
                which.setTag( R.id.action, null );
                Log.d( "onActin", " The preventing double click tag was removed." );
            }

        }, 2000 );
    }

Setting the button as clickable false upon clicking and true once it is desired to make the button clickable again is the right approach. For instance, consider the following scenario: you are making a service call upon click of a button and once the service is done you want to display a dialog. For this, once the button is clicked you can set setClickable(false) and once the service responds you will do setClicklable(true) through a reference you pass to your custom dialog. When dialog invokes isShowing() you can trigger the listener and setClicklable(true).

在kotlin

button.setOnClickListener { 
    it?.apply { isEnabled = false; postDelayed({ isEnabled = true }, 400) } //400 ms
    //do your work
}

你可以使用这种方法。通过使用后延迟,你可以照顾双击事件。

void debounceEffectForClick(查看视图){

    view.setClickable(false);

    view.postDelayed(new Runnable() {
        @Override
        public void run() {
            view.setClickable(true);

        }
    }, 500);
}
