Android TextView设置图片的大小

tv_block = (TextView) findViewById(R.id.block);

//获取资源文件Drawable d = ContextCompat.getDrawable(WorkoutDetailActivity.this,R.drawable.block);//getResources().getDrawable(R.mipmap.come_in_icon);

//必须设置图片大小，否则不显示
d.setBounds(0, 0, DensityUtil.dip2px(WorkoutDetailActivity.this,20), DensityUtil.dip2px(WorkoutDetailActivity.this,20));                               

//图片要设置到的位置，参数分别代表：左上右下
tv_block.setCompoundDrawables(d,null,null,null);
