添加设置Android应用 [英] Adding settings to android app

问题描述

这绝对是一个noob问题。我跟着指示这里 http://developer.android.com/指南/主题/ UI / settings.html＃活动当我点击设置，没有任何反应和

This is definitely a noob question. I've followed the instructions here http://developer.android.com/guide/topics/ui/settings.html#Activity and when I click on settings, nothing happens.

下面是我在MainActivity.java：

Here's what I have in MainActivity.java:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);   
    PreferenceManager.setDefaultValues(this, R.xml.preferences, false);
}

然后我有一个名为prefsActivity.java一个新的Java文件

Then I have a new java file called PrefsActivity.java

public class PrefsActivity extends PreferenceActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    addPreferencesFromResource(R.xml.preferences);
}    }

然后，我有RES / XML / preferences.xml

Then I have res/xml/preferences.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<CheckBoxPreference
    android:key="face_up"
    android:title="@string/face_up"
    android:summary="@string/face_up_desc"
    android:defaultValue="false" />
</PreferenceScreen>

我试图使其与minsdk 7如果可能的话兼容。我缺少什么？

I am trying to make it compatible with minsdk 7 if possible. What am I missing?

推荐答案

您需要打开你的活动当你点击设置按钮。如果您使用的是操作栏，使用这样的：

You need to open your activity when you click on your settings button. If your using an action bar, use something like this:

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case R.id.menu_settings:
            Intent intent = new Intent(this, SettingsActivity.class);
            startActivity(intent);
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
