在另一个活动中打开导航抽屉菜单

标签: java android android-navigation-drawer

我创建了导航抽屉菜单,现在我希望它出现在我的主要活动中。

我的主要活动中有以下代码:

    public class MainActivity extends sideMenu {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        FrameLayout contentFrameLayout = (FrameLayout) findViewById(R.id.content_frame);
        getLayoutInflater().inflate(R.layout.activity_main, contentFrameLayout);

    }}

When i run the app it crashes when entering main activity and it tells this:

**Caused by: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.**

It specifies the error is in two places:
Menu activity -

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

Main activity -

    super.onCreate(savedInstanceState);


If someone can shed some light here i'd be grateful!

2 个答案:

答案 0 :(得分:1)

您的主题已有ActionBar,因此您必须将其转换为NoActionBar

适用于整个应用程序:
 打开styles.xml并确保父级的最后一行有一个单词NoActionBar,例如

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- changed .DarkActionBar to .NoActionBar -->
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>

对于活动:
或者你可以在Manifest中为一个特定的活动更改它,就像在Manifest中添加这个atrribute

android:theme="@style/Theme.AppCompat.Light.NoActionBar"

答案 1 :(得分:0)

使用这个主题。

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