按下后如何使按钮闪烁？

Question

我想让 Mediaplayer 按钮在按下后开始闪烁，并停止闪烁，直到我按下下一个 Mediaplayer 按钮，该按钮也开始闪烁。我现在有按钮在按下时闪烁，但现在的问题是当我按下下一个按钮时如何让它们停止闪烁。现在，当我按下下一个按钮时，按钮会继续闪烁。

这是我现在使用的代码：

        mButton1 = (Button)findViewById(R.id.button1);
        mButton2 = (Button)findViewById(R.id.button2);

        mAnimation = new AlphaAnimation(1, 0);
        mAnimation.setDuration(500);
        mAnimation.setInterpolator(new LinearInterpolator());
        mAnimation.setRepeatCount(Animation.INFINITE);
        mAnimation.setRepeatMode(Animation.REVERSE);

        mButton1.setOnClickListener(new View.OnClickListener() {


            @Override
            public void onClick(View v) {
                mButton2.clearAnimation();
                mButton1.startAnimation(mAnimation);

                {
                    mp.release();
                    mp = MediaPlayer.create(Activity2.this, R.raw.audio_1);
                    mp.setLooping(true);
                    mp.start();


                }
                }
        });

        mButton2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mButton1.clearAnimation();
                mButton2.startAnimation(mAnimation);

                {
                mp.release();
                mp = MediaPlayer.create(Activity2.this, R.raw.audio_2);
                mp.setLooping(true);
                mp.start();


            }
            }
        });

试试这个方法

mButton1 = (Button)findViewById(R.id.button1);
mButton2 = (Button)findViewById(R.id.button2);

mAnimation = new AlphaAnimation(1, 0);
mAnimation.setDuration(500);
mAnimation.setInterpolator(new LinearInterpolator());
mAnimation.setRepeatCount(Animation.INFINITE);
mAnimation.setRepeatMode(Animation.REVERSE);

mBbutton1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mButton2.clearAnimation();
        mButton1.startAnimation(mAnimation);
    }
});

mBbutton2.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mButton1.clearAnimation();
        mButton2.startAnimation(mAnimation);
    }
});

请注意，在 button1 点击监听器上，您应该在 button1 中启动动画并清除 button2 的动画，反之亦然

如果您有很多按钮，请尝试将它们存储在数组中并执行逻辑

mButtons = new ArrayList<Button>();

mClickListener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //stop flashing all buttons
        for(Button button : mButtons) {
            button.clearAnimation();
        }
        //start animation on this button
        v.startAnimation(mAnimation);
    }
});

Button button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(mClickListener);
Button button2 = (Button)findViewById(R.id.button2);
button2.setOnClickListener(mClickListener);
//get as many as buttons

mButtons.add(button1);
mButtons.add(button2);
//add all the buttons to array
