Question

我尝试在一个按钮中添加播放和暂停操作这是我的代码我只是添加了播放动作，你能帮助我吗？

 fab_play_pause.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            timerHasStarted = true;
            countDownTimer.start();


            Resources res = getResources();
            Drawable drawable = res.getDrawable(R.drawable.custom_progressbar_drawable);
            final ProgressBar mProgress = (ProgressBar) rootView.findViewById(R.id.circularProgressbar);
            mProgress.setProgress(0);   // Main Progress
            mProgress.setSecondaryProgress(100); // Secondary Progress
            mProgress.setMax(100); // Maximum Progress
            mProgress.setProgressDrawable(drawable);
            mProgress.setRotation(0);

            ObjectAnimator animation = ObjectAnimator.ofInt(mProgress, "progress", 0, 100);
            animation.setDuration(startTime);
            animation.setInterpolator(new DecelerateInterpolator());
            animation.start();

        }
    });

你可以通过这个来实现它：

将其设置为默认为播放

    fab_play_pause.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
             String text = btnAdd.getText().toString();

               if(text.equalsIgnoreCase("Play")){
                  //your code
                   fab_play_pause.setText("pause")
               }
              else if(text.equalsIgnoreCase("pause"))
               {
                  //your code
                  fab_play_pause.setText("Play")
               }
            }
        });

对于Drawble：

 fab_play_pause.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                int resId = (Integer) view.getTag();

                   if(resId == R.drawable.play){
                      //your code
                      //change background for pause
                   }
                  else if(resId == R.drawable.pause)
                   {
                      //your code
                      //change background for play
                   }
                }
            });

private static final String PLAY_ICON = "playIcon";
    private static final String PAUSE_ICON = "pauseImage";

    fab_play_pause.setImageResource(R.drawable.ic_play_arrow_white_24dp);
    fab_play_pause.setTag(PLAY_ICON);
    fab_play_pause.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            String tag = (String) view.getTag();

            if (view.getTag() == PLAY_ICON){
                Toast.makeText(getContext(), "play",Toast.LENGTH_LONG).show();
                fab_play_pause.setTag(PAUSE_ICON);
            }else if (view.getTag() == PAUSE_ICON){
                Toast.makeText(getContext(), "pause",Toast.LENGTH_LONG).show();
