Question

我想创建一个进度条ProgressBar screenshot，就像给定的图像一样，星形图像应该根据时间（每秒）减少。那么，请指导我该怎么办？我正在使用倒数计时器的处理程序 timeString *我们从不同的类

获取它

select salution||' '||firstname||' '||lastname as custName , city as custCity ,state as custState,zip as custZip,  dob as custDob ,idhardtoken as custAdarNo from mstuser   ;

Answer 1

尝试以下 -

    SeekBar seekBar1 = (SeekBar)findViewById(R.id.seekBar1);
    drw = getResources().getDrawable(R.drawable.ic_launcher);
    seekBar1.setOnSeekBarChangeListener(new yourListener());

private class yourListener implements SeekBar.OnSeekBarChangeListener {

        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {


                    iSize = 100 - progress;


            tv.setText(String.valueOf(new Integer(progress)));   
            drw = resize(drw);
            seekBar.setThumb(drw);
        }

        public void onStartTrackingTouch(SeekBar seekBar) {}

        public void onStopTrackingTouch(SeekBar seekBar) {}

    }


    //Reduce size of seekbar 
    private Drawable resize(Drawable image) {
        Bitmap b = ((BitmapDrawable)image).getBitmap();

        Bitmap bitmapResized = Bitmap.createScaledBitmap(b, iSize, iSize, false);
        return new BitmapDrawable(getResources(), bitmapResized);
    }

将此添加为活动的内部类或片段需要进度条减少。

class CounterClass extends CountDownTimer {
int totalDuration;
public CounterClass(long millisInFeature, long countDownInterval) {
    // TODO Auto-generated constructor stub
    super(millisInFeature , countDownInterval);     
    this.totalDuration =millisInFeature     
}

@Override
public void onTick(long millisUntilFinished) {
    // TODO Auto-generated method stub

     int progress =((millisUntilFinished * 100 / totalDuration))
     progressbar.setProgress(progress);
}

@Override
public void onFinish() {
    // TODO Auto-generated method stub

}

oncreate（）或事件开始

(new CounterClass(30000,1000)).start();
