Question

如何从Android ActionBarActivity隐藏标题栏我已经尝试了一切，但没有取得成功。

得到那个例外：

java.lang.RuntimeException：无法启动活动 ComponentInfo {com.dan.msdashboard / com.dan.msdashboard.FirstActivity}： android.util.AndroidRuntimeException：必须调用requestFeature（）在添加内容之前

但我正在使用此代码

protected void onCreate(Bundle savedInstanceState) {
        // requestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

            // Hide the Title bar of this activity screen


        this.supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_simple);

请帮我解决。

提前致谢....

Answer 1

在onCreate之前做功能

protected void onCreate(Bundle savedInstanceState) {
        // requestWindowFeature(Window.FEATURE_NO_TITLE);

  getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);


        super.onCreate(savedInstanceState);



            // Hide the Title bar of this activity screen


        this.supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_simple);

Answer 2

在调用super.onCreate()之前设置窗口标志：

protected void onCreate(Bundle savedInstanceState) {
        getWindow()...
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_simple);
}

Answer 3

尝试如下

     // requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

        // Hide the Title bar of this activity screen
    this.supportRequestWindowFeature(Window.FEATURE_NO_TITLE);

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_simple);

希望这会对你有所帮助。
