Android Seekbar as Dialog

Question

我创建按钮来更改音量，我希望onClick，seekbar显示为dialog（但不是涵盖的那种屏幕，并且不允许与按钮下方的屏幕上的其他元素进行交互）几秒后它会消失。我不想使用 android 提供涵盖整个活动。如何解决这个问题？也有任何图书馆来实现这个目标吗？

您可以使用WindowManager将SeekBar添加到窗口中，同时也可以与您的活动或其他活动进行互动。发布一个处理程序以在指定时间后删除该视图。

        View yourSeekBarView = inflator.inflate(R.layout.your_layout_xml,null,false);
        WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                150,
                50,
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
                0 | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
                PixelFormat.TRANSLUCENT);  
        params.gravity = Gravity.CENTER_HORIZONTAL |Gravity.TOP;      
        WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
        wm.addView(oView, params);

wm.removeView(yourSeekBarView);

将您的搜索栏放在xml布局中的按钮下方，使用alpha =＆＃34; 0＆＃34;，然后尝试：

    SeekBar mSeekbar;
    int delay = 1000;
    Button mButton;
    Handler mHandler;
    Runnable mRunnable = new Runnable() {
        @Override
        public void run() {
            Animation anim = new AlphaAnimation(1, 0);
            anim.setDuration(500);
            mSeekbar.startAnimation(anim);
        }
    };


    //inside onCreate (or wherever you decide)
    mHandler = new Handler(); //(android.os)
    mButton = (Button) findViewById(R.id.button1);

    mSeekbar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
            mHandler.removeCallbacks(mRunnable);
        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            mHandler.postDelayed(mRunnable, delay);
        }
    });


    mButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if(mSeekbar.getAlpha() == 0) {
                Animation anim = new AlphaAnimation(0, 1);
                anim.setDuration(500);
                anim.setAnimationListener(new Animation.AnimationListener() {
                    @Override
                    public void onAnimationStart(Animation animation) {

                    }

                    @Override
                    public void onAnimationEnd(Animation animation) {
                        mHandler.postDelayed(mRunnable, delay);
                    }

                    @Override
                    public void onAnimationRepeat(Animation animation) {

                    }
                });
                mSeekbar.startAnimation(anim);
            }
        }
    });
