局部核心代码：
bitmap = Bitmap.createBitmap(mSize.x, mSize.y, Config.ARGB_8888);
				cacheBitmap = Bitmap.createBitmap(mSize.x, mSize.y, Config.ARGB_8888);
				cacheCanvas = new Canvas();
				cacheCanvas.setBitmap(cacheBitmap);
				cacheCanvas.drawBitmap(bitmap, 0, 0, null);
				mSearchView.setImageBitmap(bitmap);
