/**高仿众筹app**/

@Override
protected void onCreate(Bundle savedInstanceState) {

requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉标题栏

	StatusBarCompat.compat(getActivity());//4.4以上沉浸式适配

	super.onCreate(savedInstanceState);

}

默认的style更改

values-v21 style.xml 文件更改

修改配置文件

android:theme="@style/AppTheme.NoActionBar"
