1、效果图

2、自定义代码：

		this.context = context;
		init();
	}

	public ImageTextView(Context context, AttributeSet attrs, int defStyle) {

	}

		setOnClickListener(this);
	}
	
	@Override
	protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
		super.onMeasure(widthMeasureSpec, heightMeasureSpec);

	}
	
	
	@Override

		canvas.drawBitmap(imageBitmap, 10, imageTop, mImagePaint);
		canvas.drawText("打开",imageBitmap.getWidth()+20, textTop, mTextPaint);
	}
