我有一个非常令人沮丧的错误,我无法解释。我创建了一个 Android 应用程序,用于Android AppCompat使其与旧版本兼容。这是我的主要活动布局文件:
Android AppCompat
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <!-- As the main content view, the view below consumes the entire space available using match_parent in both dimensions. --> <FrameLayout android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" /> <!-- android:layout_gravity="start" tells DrawerLayout to treat this as a sliding drawer on the left side for left-to-right languages and on the right side for right-to-left languages. If you're not building against API 17 or higher, use android:layout_gravity="left" instead. --> <!-- The drawer is given a fixed width in dp and extends the full height of the container. --> <fragment android:id="@+id/navigation_drawer" android:layout_width="@dimen/navigation_drawer_width" android:layout_height="match_parent" android:layout_gravity="start" android:name="com.fragment.NavigationDrawerFragment" /> </android.support.v4.widget.DrawerLayout>
这是我活动的主要代码:
public class MainActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } }
这里的主要问题是:上面的代码在几乎设备(模拟设备,或一些真实设备)上运行流畅。但是当我在三星 S3 上运行它时。它注意到这个错误:
java.lang.RuntimeException: Unable to start activity ComponentInfo{view.MainActivity}: android.view.InflateException: Binary XML file line #25: Error inflating class fragment at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2081) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2106) at android.app.ActivityThread.access$700(ActivityThread.java:134) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1217) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4856) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1007) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:774) at dalvik.system.NativeStart.main(Native Method) Caused by: android.view.InflateException: Binary XML file line #25: Error inflating class fragment at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:704) at android.view.LayoutInflater.rInflate(LayoutInflater.java:746) at android.view.LayoutInflater.inflate(LayoutInflater.java:489) at android.view.LayoutInflater.inflate(LayoutInflater.java:396) at android.view.LayoutInflater.inflate(LayoutInflater.java:352) at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:316) at android.app.Activity.setContentView(Activity.java:1901) at android.support.v7.app.ActionBarActivity.superSetContentView(ActionBarActivity.java:208) at android.support.v7.app.ActionBarActivityDelegateICS.setContentView(ActionBarActivityDelegateICS.java:111) at android.support.v7.app.ActionBarActivity.setContentView(ActionBarActivity.java:76)
请告诉我如何修复错误,谢谢:)
经过长时间的调试,我已经解决了这个问题。(虽然我仍然无法解释为什么)。我将属性更改android:name为class. (虽然在 Android Document 上,他们说这些属性是相同的,但它有效!!!)
android:name
class
所以,它应该从:
android:name="com.fragment.NavigationDrawerFragment"
至
class = "com.fragment.NavigationDrawerFragment"
所以,新的布局应该是:
<!-- As the main content view, the view below consumes the entire space available using match_parent in both dimensions. --> <FrameLayout android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" /> <!-- android:layout_gravity="start" tells DrawerLayout to treat this as a sliding drawer on the left side for left-to-right languages and on the right side for right-to-left languages. If you're not building against API 17 or higher, use android:layout_gravity="left" instead. --> <!-- The drawer is given a fixed width in dp and extends the full height of the container. --> <fragment android:id="@+id/navigation_drawer" android:layout_width="@dimen/navigation_drawer_width" android:layout_height="match_parent" android:layout_gravity="start" class = "com.fragment.NavigationDrawerFragment" />
希望这有帮助:)
