Android TextView設置圖片的大小

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

//獲取資源文件
Drawable d = ContextCompat.getDrawable(WorkoutDetailActivity.this,R.drawable.block);//getResources().getDrawable(R.mipmap.come_in_icon);

//必須設置圖片大小，否則不顯示

d.setBounds(0, 0, DensityUtil.dip2px(WorkoutDetailActivity.this,20), DensityUtil.dip2px(WorkoutDetailActivity.this,20));                               

//圖片要設置到的位置，參數分別代表：左上右下

tv_block.setCompoundDrawables(d,null,null,null);
