Question

我从Android Studio

创建了一个Empty项目

从左侧的导航抽屉中，我编辑了这样的控件

<group android:checkableBehavior="single">
    <item android:id="@+id/nav_blog"
        android:title="Blog" />
    <item android:id="@+id/nav_task"
        android:title="Task" />
</group>

我点击nav_blog

我将此作为活动

if (id == R.id.nav_blog) {
        setContentView(R.layout.layout_blog);
    } else if (id == R.id.nav_task) {
setContentView(R.layout.layout_task);
    }

res / layout

内

我有nav_task.xml和layout_task.xml

但是当我点击导航抽屉上的侧栏时，我的应用程序总是在模拟器中崩溃并显示此日志

我在做什么错误..

当我点击导航抽屉上的项目时，如何显示布局。

在主要活动中

更新：

这是AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.sulthan.sa" >

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".SysMain"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

我想我应该添加一些内容。但我不清楚。

我正在做的错误是什么？如何解决这个问题？

Answer 1

你做错了。首先创建片段，然后onNavigationItemSelected调用这些片段。您可以按照本文进行参考。 Using Fragments with the Navigation Drawer Activity

Android在＆＃39; onNavigationItemSelected＆＃39;上显示布局来自导航抽屉
