我正在进行设置活动。我接受了帮助 http://developer.android.com/guide/topics/ui/settings.html

我创建了一个包含以下Java代码的活动

import android.os.Bundle;
import android.preference.PreferenceActivity;

public  class SettingsActivity extends PreferenceActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    addPreferencesFromResource(R.xml.pref_user);
}

}

XML文件

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

<PreferenceCategory
    android:title="Settings">
</PreferenceCategory>

</PreferenceScreen>

我得到的例外是

要检查问题，我评论了addPreferencesFromResource（R.xml.pref_user），但我仍然遇到了同样的错误。

这是build.gradle文件中的配置。

compileSdkVersion 23
buildToolsVersion "22.0.1"

defaultConfig {
    applicationId ""
    minSdkVersion 14
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}

1 个答案:

答案 0 :(得分：0)

假设你的applicationId实际上并非空白，我能够正常运行，没有任何问题。我怀疑有更多的代码导致错误，因为错误是抱怨无法找到Button。

如果您尝试使用的代码中有其他位置的按钮，则需要确保您通过Id找到它，例如：

Button myButton = (Button)findViewById(R.id.someButton);
