ActionBarView 膨胀崩溃

Question

我收到了一些用户的崩溃报告。他们使用的是三星 SPH-M840 Android 4.1 版。我正在膨胀的布局是一个简单的FrameLayout，里面有一个fragment 标签。我正在使用 actionbar-compat。

编辑：这是 xml 和 onCreate 的 AlarmMainActivity：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <fragment class="com.cpsolutions.alarmbase.alarm.AlarmListFragment"
          android:id="@+id/alarm_list_frag"
          android:layout_width="match_parent"
          android:layout_height="match_parent"/>
</FrameLayout>

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    alarmFrag = (AlarmListFragment) getSupportFragmentManager().findFragmentById(R.id.alarm_list_frag);
    preferenceFrag = (AlarmPreferenceFragment) getSupportFragmentManager().findFragmentById(R.id.preference_list_frag);
    if(preferenceFrag != null) {
        isTwoPane = true;
    }
}

Answer 1

你有一个NullPointerException@

android.server.BluetoothPanProfileHandler.createNewTetheringAddressLocked(BluetoothPanProfileHandler.java:332)

Answer 2

使用的布局文件有问题：

com.cpsolutions.alarmbase.alarm.AlarmMainActivity.java

在第 57 行将有一个 setContentView 参数为 R.layout.{在此处插入名称}

转到res/layout/{在此处插入姓名}.xml 并解决问题。

如果您需要帮助，请在此处发布 XML 文件。

错误是因为它不能为 ActionBarView 充气。请张贴班级声明。 （它继承了什么或extends）
