【问题描述】:

我正在尝试设置带有汉堡菜单的工具栏,这是我的代码,并且 错误是:

这个 Activity 已经有一个由窗口装饰提供的操作栏。 不要请求Window.FEATURE_SUPPORT_ACTION_BAR 并设置 在您的主题中将 windowActionBar 设置为 false 以使用工具栏。

问题是我不知道我从哪里得到错误,并且 还有我尝试了一切的事实。

MainActivity.java

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    txResult = (TextView) findViewById(R.id.txResult);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);}

// Set a Toolbar to replace the ActionBar.


// Find our drawer view



private void setupDrawerContent(NavigationView navigationView) {
    navigationView.setNavigationItemSelectedListener(
            new NavigationView.OnNavigationItemSelectedListener() {
                @Override
                public boolean onNavigationItemSelected(MenuItem menuItem) {
                    selectDrawerItem(menuItem);
                    return true;
                }
            });
}

public void selectDrawerItem(MenuItem menuItem) {
    // Create a new fragment and specify the planet to show based on
    // position
    Fragment fragment = null;

    Class fragmentClass;
    switch(menuItem.getItemId()) {
        case R.id.nav_first_fragment:
            fragmentClass = MainActivity.class;
            break;
        case R.id.nav_second_fragment:
            fragmentClass = SecondActivity.class;
            break;
        case R.id.nav_third_fragment:
            fragmentClass = ThirdActivity.class;
            break;
        default:
            fragmentClass = MainActivity.class;
    }

    try {
        fragment = (Fragment) fragmentClass.newInstance();
    } catch (Exception e) {
        e.printStackTrace();
    }

    // Insert the fragment by replacing any existing fragment
    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();

    // Highlight the selected item, update the title, and close the drawer
    menuItem.setChecked(true);
    setTitle(menuItem.getTitle());
    mDrawer.closeDrawers();
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // The action bar home/up action should open or close the drawer.
    switch (item.getItemId()) {
        case android.R.id.home:
            mDrawer.openDrawer(GravityCompat.START);
            return true;
    }

    return super.onOptionsItemSelected(item);
}

【问题讨论】:

  • 去掉主题属性中的windowActionBar,看看是否有效。
  • 我添加了我的活动,我删除了windowActionBar,没有任何反应
  • 你能告诉我你的MainActivityAndroidManifest.xml 吗?您目前已为CaptureActivity 发布了AndroidManifest.xml

标签: android


【解决方案1】:

你不需要这个:

<item name="windowActionBar">false</item>

您的主题父 Theme.AppCompat.Light.NoActionBar 已经声明没有操作栏(但工具栏)。

【讨论】:

    【解决方案2】:

    我的一项活动遇到了类似的问题,我遇到了类似的问题:

    在styles.xml中:

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>
    

    在 manifest.xml 中:

    <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:theme="@style/AppTheme">
    
            ......
    
            <activity
            android:name=".ServicesActivity"
            android:theme="@style/AppTheme.NoActionBar"
            android:exported="false" />
    
        </application>
