TextView使用Paint設置下劃線刪除線效果

TextView tv1 = findViewById(R.id.tv1);
tv1.getPaint().setFlags(Paint.UNDERLINE_TEXT_FLAG | Paint.ANTI_ALIAS_FLAG);//設置下劃線

TextView tv2 = findViewById(R.id.tv2);
tv2.getPaint().setFlags(Paint.STRIKE_THRU_TEXT_FLAG | Paint.ANTI_ALIAS_FLAG);//設置刪除線

TextView tv3 = findViewById(R.id.tv3);
tv3.getPaint().setFakeBoldText(true); //加粗
