    //android中为textview动态设置字体为粗体
     TextView textView = (TextView)findViewById(R.id.textView);
     TextPaint tp = textView .getPaint();
     tp.setFakeBoldText(true);  ```   
``` 

2. 推荐这种方式，这种方式完美的解决的我需要选中的Item字体加粗。  
 

```//android中为textview动态设置字体为粗体
 TextView textView = (TextView)findViewById(R.id.textView);
 textView .setTypeface(Typeface.defaultFromStyle(Typeface.BOLD));
//设置不为加粗
 textView.setTypeface(Typeface.defaultFromStyle(Typeface.NORMAL));

        ON_CREATE,

        ON_STOP,
        ON_DESTROY,
        ON_ANY
    }
