Android 应用程序打开后立即关闭

Question

我的原型 Android 应用程序（我应该提到这是我的第一个）每当我通过 Eclipse 运行它时就会崩溃，只要它打开。我搜索过这个网站和许多其他网站，这个问题似乎很常见，但对我来说却不是这样。我已经检查了 AndroidManifest.xml 文件，并且相当确定它是正确的，但我还是将其附在此处。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.cyphr"
  android:versionCode="1"
  android:versionName="1.0">
<uses-sdk android:minSdkVersion="7" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".NSBHSActivity"
              android:label="@string/app_name"
              android:theme="@android:style/Theme.NoTitleBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".DayActivity"
              android:label="@string/app_name">
    </activity>
    <activity android:name=".WeekActivity"
              android:label="@string/app_name">
    </activity>

</application>

据我所知，这是从程序启动到终止的 logcat 消息。

根据要求，来自 NSBHSActivity 的 onCreate()：

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

    Resources res = getResources(); // Resource object to get Drawables
    TabHost tabHost = getTabHost();  // The activity TabHost
    TabHost.TabSpec spec;  // Reusable TabSpec for each tab
    Intent intent;  // Reusable Intent for each tab

    // Create an Intent to launch an Activity for the tab (to be reused)
    intent = new Intent().setClass(this, DayActivity.class);

    // Initialize a TabSpec for each tab and add it to the TabHost
    spec = tabHost.newTabSpec("day").setIndicator("Day",
                      res.getDrawable(R.drawable.ic_tab_day))
                  .setContent(intent);
    tabHost.addTab(spec);

    // Do the same for the other tabs
    intent = new Intent().setClass(this, WeekActivity.class);
    spec = tabHost.newTabSpec("week").setIndicator("Week",
                      res.getDrawable(R.drawable.ic_tab_day))
                  .setContent(intent);
    tabHost.addTab(spec);

    tabHost.setCurrentTab(1);

}

如果您需要额外信息，请发表评论。另外，正如我所说，这是我的第一个 Android 应用程序，但我在 Java 方面有很好的经验。

Answer 1

我不认为 android:theme="@android:style/Theme.NoTitleBar" 是一个有效的标签..删除它并检查。

Answer 2

您已将应用程序标记放在清单标记之外：像这样使用：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.cyphr"
  android:versionCode="1"
  android:versionName="1.0">
<uses-sdk android:minSdkVersion="7" >

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".NSBHSActivity"
              android:label="@string/app_name"
              android:theme="@android:style/Theme.NoTitleBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".DayActivity"
              android:label="@string/app_name">
    </activity>
    <activity android:name=".WeekActivity"
              android:label="@string/app_name">
    </activity>

</application>
</manifest>

Answer 3

我终于发现这是因为图像文件名的原因。它们必须是 ic_tab_day_grey.png 和 ic_tab_day_white.png 状态列表才能接受它们。耶！
感谢大家的帮助！
