android应用中去掉标题栏需要注意的地方

1、确定自己的MainActivity继承自Activity

public class MainActivity extends Activity {

2、在setContentView(R.layout.activity_main)之前增加代码

requestWindowFeature(Window.FEATURE_NO_TITLE);

3、示例代码如下：

public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //取消标题栏        requestWindowFeature(Window.FEATURE_NO_TITLE);        setContentView(R.layout.activity_main);    }}
