安卓TextView中的文本加上横线或者下划线

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

TextView tv = (TextView) findViewById(R.id.tv);

//加上中划线

// tv.getPaint().setFlags(Paint. STRIKE_THRU_TEXT_FLAG);

//加上下划线

tv.getPaint().setFlags(Paint. UNDERLINE_TEXT_FLAG );

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

}
