我有一个自定义视图类，可以将位图绘制到视图中
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
Log.d("Log","Called with w and h " + w +"," + h);
// method called multiple times but initialized just once
if (wheelHeight == 0 || wheelWidth == 0) {
wheelHeight = h;
wheelWidth = w;
// resize the image
Matrix resize = new Matrix();
resize.postScale((float)0.60, (float)0.60);
imageScaled = Bitmap.createBitmap(imageOriginal, 0, 0, imageOriginal.getWidth(),
imageOriginal.getHeight(), resize, false);
// translate the matrix to the image view's center
float translateX = wheelWidth / 2 - imageScaled.getWidth() / 2;
float translateY = wheelHeight / 2 - imageScaled.getHeight() / 2;
matrix.postTranslate(translateX, translateY);
WheelMenu.this.setImageBitmap(imageScaled);
WheelMenu.this.setImageMatrix(matrix);
//This has no affeect on the height of the view
setMinimumHeight(imageScaled.getHeight());
Log.d("Image","the height of the control is" +getHeight());
Log.d("Image","the height of the bitmap is" +imageScaled.getHeight());
}
}
我要做的是将视图的高度更改为位图的高度。设置其高度不会影响视图。我做错了什么？
亲切的问候
