Question

我正在android studio中开发一个程序。我想当我点击一个按钮然后动作将同时执行。功能： 1st - 开始计算点击次数第二 - 5秒后该按钮禁用

setDelay = new Handler();

    btn = (Button) findViewById(R.id.bt);

    final Button disableMe = (Button) findViewById(R.id.bt);
    final  TextView text = (TextView) findViewById(R.id.timeUp);
    btn.setOnClickListener(new View.OnClickListener(){
        @Override
        public void  onClick(View v){
            startDelay = new Runnable(){
                @Override
                public void run(){
                    text.setText("Time Up!");
                    disableMe.setEnabled(false);
                }
            };
            setDelay.postDelayed(startDelay, 5000);

        }
    });


    txv = (TextView) findViewById(R.id.tx);

    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mCounter ++;
            txv.setText(Integer.toString(mCounter));

        }


    });

Answer 1

像这样创建新列表：

ArrayList <View.OnClickListener> clickList = new ArrayList<>();

然后添加所有听众：

final Runnable startDelay;
clickList.add(new View.OnClickListener(){
        @Override
        public void  onClick(View v){
            if (startDelay != null)
                return;
            startDelay = new Runnable(){
                @Override
                public void run(){
                    text.setText("Time Up!");
                    disableMe.setEnabled(false);
                }
            };
            setDelay.postDelayed(startDelay, 5000);
        }
    });

clickList.add(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mCounter ++;
            txv.setText(Integer.toString(mCounter));

        }
    });

然后，在你的按钮中添加这个监听器：

btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            for (View.OnClickListener c : clickList)
                c.onClick(view);
        }
    });

Answer 2

只需使用class MyClass extends AnotherClass { public $course_id = 0; }变量来判断是否已启用禁用boolean：

Runnable

将button.setOnClickListener(new View.OnClickListener() { boolean disableRunnableStarted = false; Runnable disableRunnable = new Runnable(){ @Override public void run(){ //Running on UI thread to update button MainActivity.this.runOnUiThread(new Runnable() { @Override public void run() { button.setEnabled(false); } }); } }; @Override public void onClick(View v) { if(!disableRunnableStarted) { Log.d(TAG,"Starting disable runnable and incrementing counter..."); new Handler().postDelayed(disableRunnable,5000); disableRunnableStarted = true; //Here increment your counter } else { Log.d(TAG,"Just incrementing counter..."); //Here increment your counter } } });替换为MainActivity的名称，如果Activity代替Fragment执行。

这可以帮助

private int clicks = 0;


button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(final View v) {
        final Button b = (Button)v;
        if (clicks == 0){
            // Means its the first time that a user click the button
            // Start a thread that is going to disable the button after 5 seconds from first click
            new Thread(new Runnable() {
                @Override
                public void run() {
                    try {
                        Thread.sleep(5000);
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                b.setText("Time up");
                                b.setEnabled(false);
                                // Showing user clicks after button is disabled 
                                showClicks();
                            }
                         });
                     } catch (InterruptedException e) {
                         e.printStackTrace();
                     }
                 }
             }).start();
         }
         // Here we are just counting  . . . . including the first click
         countClicks();
    }
});

点击点击方法

private void countClicks(){
        ++clicks;
        // You can update your text view here
}

显示总点击次数

private void showClicks(){
        Toast.makeText(this, Integer.toString(clicks), Toast.LENGTH_SHORT).show();
}

两个onClick同时执行一个按钮
