fairytale110 / bezierseekbar Goto Github PK

i have a button that changes the value of the seekbar to a random number each time i click on it,
but that doesn't effect the seekbar, when i added invalidate() on the seekbar it changes the value but the indicator doesn't move to the correct position.

final BezierSeekBar brightnessSeekBar; brightnessSeekBar = findViewById(R.id.xx); Button bb = findViewById(R.id.bb); bb.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { brightnessSeekBar.setValueSelected(new Random().nextInt((300) + 1) -150); Log.d("TAG", "onClick: "+brightnessSeekBar.getValueSelected()); brightnessSeekBar.invalidate(); } });

thank you.

宽度设为matchparent会比较难以选择首尾的值，设置padding没有效果，设置margin滑动到尽头显示半个圆。
