此代码中是否有任何错误设置首选项。因为我收到错误"不幸(应用程序名称)已停止。请帮我。是否有替代方法而不是addPreferenceFromResource(R.xml.preference);
package example.katta;
import android.os.Bundle;
import android.preference.PreferenceActivity;
import android.preference.PreferenceFragment;
public class Preference extends PreferenceActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
getFragmentManager().beginTransaction().replace(android.R.id.content,new MyPreferenceFragment()).commit();
}
public static class MyPreferenceFragment extends PreferenceFragment
{
@Override
public void onCreate(final Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preference);
}
}
}
这是我的xml文件:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
<EditTextPreference
android:key="Name"
android:summary="Enter Your Name"
android:title="EditText" />
<CheckBoxPreference
android:defaultValue="true"
android:key="checkbox"
android:summary="Check This Box"
android:title="Checkbox" />
<ListPreference
android:entries="@array/list"
android:entryValues="@+array/listvalue"
android:key="list"
android:summary="This is The List to choose From"
android:title="List" />
</PreferenceScreen>
这是我的数组字符串。
<string-array name="list">
<item>Option 1</item>
<item>Option 2</item>
<item>Option 3</item>
<item>Option 4</item>
</string-array>
<string-array name="value">
<item>1</item>
<item>2</item>
<item>3</item>
<item>4</item>
</string-array>
</resources>
答案 0 :(得分:0)
此行无效:
android:entryValues="@+array/listvalue"
您应该将其替换为:
android:entryValues="@array/listvalue"
修改强>
数组资源有另一个名称:
android:entryValues="@array/value"
