FATAL EXCEPTION主要Android应用程序

标签： android eclipse exception preferences fatal-error

我目前正在开发Android应用。单击“菜单”时，菜单会显示，但如果选择“首选项”，则会崩溃。如果单击“新建”，它可以正常工作。我不知道发生了什么事。我是Android App开发和eclipse IDE的新手，所以一切都有帮助。这是LogCat：

以下是崩溃时调用的方法：

/** when menu button option selected */
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.menu_options:
        startActivity(new Intent(this, WordSearchPreferences.class));
        return true;
    case R.id.menu_new:
        control.newWordSearch();
        return true;
    }return super.onOptionsItemSelected(item);
}

这是用于此的preferences.xml：

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <ListPreference android:key="@string/prefs_size"
    android:title="@string/size" android:defaultValue="10"
    android:summary="@string/prefs_size_summary"
    android:entryValues="@array/sizes_list_values"
    android:entries="@array/sizes_list_labels" />
<ListPreference android:key="@string/prefs_category"
    android:title="@string/category" android:defaultValue="@string/RANDOM"
    android:summary="@string/prefs_category_summary"
    android:entryValues="@array/categories_list_values"
    android:entries="@array/categories_list_labels" />
<ListPreference android:key="@string/prefs_touch_mode"
    android:title="@string/input_type" android:defaultValue="@string/DRAG"
    android:summary="@string/prefs_touch_mode_summary"
    android:entryValues="@array/touch_mode_list_values"
    android:entries="@array/touch_mode_list_labels" />
<ListPreference android:key="@string/PREFS_THEME"
    android:title="@string/THEME" android:defaultValue="@string/THEME_ORIGINAL"
    android:summary="@string/PREFS_THEME_SUMMARY"
    android:entryValues="@array/THEME_VALUES"
    android:entries="@array/THEME_LABELS" />
</PreferenceScreen>

答案 0 :(得分：5)

ListPreference使用String.format()生成首选项的摘要，因此您可以通过%s混合来自首选项本身的数据。您似乎在说明中使用了%或某些令人困惑的内容String.format()。请确保@string/prefs_size_summary和其他人的值与String.format()一致。

此外，通常您不会为android:key使用字符串资源，因为您不会翻译您的偏好键。仅对实际翻译的内容使用字符串资源。
