我正在尝试创建一个设置活动，该用户位于个人资料屏幕上，并且能够单击设置按钮来访问设置活动。但是，尝试运行设置活动时，应用程序崩溃。
我已经查看了运行时错误，并且我相信pref_main.xml是引起问题的文件。
<?xml version="1.0" encoding="utf-8"?>

public static class MainPreferenceFragment extends PreferenceFragment {
@Override

super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.pref_main);
// EditText Listeners
bindPreferenceSummaryToValue(findPreference(getString(R.string.key_full_name)));
bindPreferenceSummaryToValue(findPreference(getString(R.string.key_username)));
bindPreferenceSummaryToValue(findPreference(getString(R.string.key_birthday)));
bindPreferenceSummaryToValue(findPreference(getString(R.string.key_email)));
// notification preference change listener
bindPreferenceSummaryToValue(findPreference(getString(R.string.key_ringtone)));
}
}
这是我查看运行时错误时得到的结果：
E/AndroidRuntime: FATAL EXCEPTION: main
Process: app.debata.com.debata, PID: 8085
java.lang.RuntimeException: Unable to start activity ComponentInfo{app.debata.com.debata/app.debata.com.debata.SettingsActivity}: android.view.InflateException: Binary XML file line #2: Error inflating class Debata
And in the Runtime error message I had a line that said this:
app.debata.com.debata.SettingsActivity$MainPreferenceFragment.onCreate(SettingsActivity.java:37)
如果您参考上面的代码并查看MainPreferenceFragement类中的onCreate方法，则该代码中就存在运行时错误。该方法是SettingsActivity.java文件的一部分。
有人可以告诉我为什么尝试运行设置活动时我的android应用程序崩溃吗？
