android seekbar怎么调触控范围

Answer 1

//mCurrentView 是Seekbar的父亲

private void enlargeSeekBar(){

mCurrentView.setOnTouchListener(new OnTouchListener(){

@Override
public boolean onTouch(View v, MotionEvent event) {
Rect seekRect = new Rect();
mSeekBar.getHitRect(seekRect);

if((event.getY() >= (seekRect.top-50)) && (event.getY()<= (seekRect.bottom+50))){

float y = seekRect.top + seekRect.height()/2;
//seekBar only accept relative x
float x = event.getX()-seekRect.left;
if(x <0) {
x=0;
}
else if(x > seekRect.width()) {
x= seekRect.width();
}
MotionEvent me = MotionEvent.obtain(event.getDownTime(), event.getEventTime(),
event.getAction(), x, y, event.getMetaState());
return mSeekBar.onTouchEvent(me);

}
return false;

}

});
}
