DrawableIndicator crash

[Cmahjong]

修改了一下，测试没有问题

/**

• Drawable指示器 */ public class DrawableIndicator extends BaseIndicator { private Bitmap normalBitmap; private Bitmap selectedBitmap;

  /**

  • 实例化Drawable指示器 ，也可以通过自定义属性设置
  • @param context
  • @param normalResId
  • @param selectedResId */ public DrawableIndicator(Context context, @DrawableRes int normalResId, @DrawableRes int selectedResId) { super(context); normalBitmap=drawableToBitmap(getResources().getDrawable(normalResId)); selectedBitmap=drawableToBitmap(getResources().getDrawable(selectedResId)); // normalBitmap = BitmapFactory.decodeResource(getResources(), normalResId); // selectedBitmap = BitmapFactory.decodeResource(getResources(), selectedResId); }

  public DrawableIndicator(Context context) { this(context, null); }

  public DrawableIndicator(Context context, AttributeSet attrs) { this(context, attrs, 0); }

  public DrawableIndicator(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.DrawableIndicator); if (a != null) { BitmapDrawable normal = (BitmapDrawable) a.getDrawable(R.styleable.DrawableIndicator_normal_drawable); BitmapDrawable selected = (BitmapDrawable) a.getDrawable(R.styleable.DrawableIndicator_selected_drawable); normalBitmap = normal.getBitmap(); selectedBitmap = selected.getBitmap(); } }

  @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); int count = config.getIndicatorSize(); if (count <= 1) { return; } setMeasuredDimension(selectedBitmap.getWidth() (count - 1) + selectedBitmap.getWidth() + config.getIndicatorSpace() (count - 1), Math.max(normalBitmap.getHeight(), selectedBitmap.getHeight())); }

  @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); int count = config.getIndicatorSize(); if (count <= 1 || normalBitmap == null || selectedBitmap == null) { return; }

  float left = 0;
  for (int i = 0; i < count; i++) {
      canvas.drawBitmap(config.getCurrentPosition() == i ? selectedBitmap : normalBitmap, left, 0, mPaint);
      left += normalBitmap.getWidth() + config.getIndicatorSpace();
  }

  } public static Bitmap drawableToBitmap (Drawable drawable) {

  if (drawable instanceof BitmapDrawable) {
      return ((BitmapDrawable)drawable).getBitmap();
  }
  
  Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
  Canvas canvas = new Canvas(bitmap);
  drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
  drawable.draw(canvas);
  
  return bitmap;

  }

}

作者看到过后可以直接关掉，希望这个库的Bug越来越少，用的人越来越多，感谢作者的开源提高我们的开发效率
