xml:

android:thumb="@drawable/seekbar_thumb"

seekbar_thumb.xml:

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"><!-- 普通無焦點狀態 -拖動按鈕 --><item android:drawable="@drawable/tiny" android:state_focused="false" android:state_pressed="false"/><!-- 有焦點狀態 --><item android:drawable="@drawable/tiny" android:state_focused="true" android:state_pressed="false"/><!-- 有焦點 --><item android:drawable="@drawable/tiny" android:state_focused="true"/></selector>

修改為：

private int seekWidth = 60;private int seekHeight = 30;private SeekBar seek; seek = (SeekBar) findViewById(R.id.seekBar);Drawable drawable = getNewDrawable(HandDraw.this,R.drawable.tiny, seekWidth, seekHeight);seek.setThumb(drawable); //調用函數縮小圖片public BitmapDrawable getNewDrawable(Activity context, int restId, int dstWidth, int dstHeight){Bitmap Bmp = BitmapFactory. decodeResource(context.getResources(), restId);Bitmap bmp = Bmp.createScaledBitmap(Bmp, dstWidth, dstHeight, true);BitmapDrawable d = new BitmapDrawable(bmp);Bitmap bitmap = d.getBitmap(); if (bitmap.getDensity() == Bitmap.DENSITY_NONE) { d.setTargetDensity(context.getResources().getDisplayMetrics()); }return d;}
