我希望创建一个自定义的 Android
这是我的代码:
但是当我移动滑块时,它会回到进度条的开头。有没有人知道如何将自定义滑块与进度条位置一起移动?
SeekBar
,其中拇指内含文本以显示当前查找位置。这是我的代码:
SeekBar sb;
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.custom_seek_bar_activity);
sb = (SeekBar)findViewById(R.id.slider);
sb.setMax(100);
sb.setProgress(10);
BitmapDrawable bd = writeOnDrawable(R.drawable.star2, Double.toString(50));
sb.setThumb(bd);
sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener(){
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
int pos = sb.getProgress();
double star = pos/(20.0);
TextView tv = (TextView)findViewById(R.id.percent);
tv.setText(Double.toString(star)+"%");
BitmapDrawable bd = writeOnDrawable(R.drawable.star2, Double.toString(star));
bd.setBounds(new Rect(0,0,
bd.getIntrinsicWidth(),
bd.getIntrinsicHeight()
));
seekBar.setThumb(bd);
}
@Override
public void onStartTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
}
@Override
public void onStopTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
}
});
}
public BitmapDrawable writeOnDrawable(int drawableId, String text){
Bitmap bm = BitmapFactory.decodeResource(getResources(), drawableId).copy(Bitmap.Config.ARGB_8888, true);
Paint paint = new Paint();
paint.setStyle(Style.FILL);
paint.setColor(Color.BLACK);
paint.setTextSize(10);
Canvas canvas = new Canvas(bm);
canvas.drawText(text, 0, bm.getHeight()/2, paint);
return new BitmapDrawable(bm);
}
