起自preferenceActivity内的另一个preferenceActivity [英] Starting custom PreferenceActivity INSIDE another PreferenceActivity

问题描述

在我的配置活动，我需要在显示的内容的preVIEW在页面中配置的顶部有一个固定视图创建preference屏幕。我不想改变主preference屏幕（我已经为一个独立的活动），我想一个嵌套preferencescreen不同的布局。

Inside my Configuration activity i need to create a preference screen with a fixed View at the top showing a preview of content configured in the page. I don't want to change the main preference screen (i have already a separate activity for that) i want a different layout for a "nested" preferencescreen.

我已经试过被指定preference屏幕内的意向然而，当我对这个选择没有任何反应和活动进入超时点击......活动是正确的配置清单（并延伸ConfigureActivity为主人做）。

What i've tried is specifying an Intent inside the preference screen however when i click on this options nothing happens and activity goes into timeout... Activity is correctly configured on the manifest (and extends ConfigureActivity as the main one does).

  <PreferenceScreen 
    android:key="inner"
    android:title="Title" 
    android:summary="Summary"
    >
    <intent 
      android:action="android.appwidget.action.APPWIDGET_CONFIGURE" 
      android:targetPackage="my.package.lib" 
      android:targetClass="my.package.lib.ConfigureClass" 
      />
  </PreferenceScreen>

另一个想法可以创建自定义preference即启动另外一个配置活动，可能这项工作？将是正确/接受有多个配置的活动？

Another idea could be creating a custom "preference" that launches another configuration activity, could this work? Would be correct/acceptable to have multiple configuration activities?

推荐答案

在主ConfigureActivity以下code工作，但是我不知道如果一个干净的方式做我想做的。可能有人证实？

The following code on the main ConfigureActivity works however i don't know if its a clean way to do what i want. Could someone confirm?

PreferenceScreen b = (PreferenceScreen) findPreference("my_empty_preference_screen");       
b.setOnPreferenceClickListener(new OnPreferenceClickListener() {
    @Override
    public boolean onPreferenceClick(Preference preference) {
        Intent intent = new Intent(ConfigureActivity.this, ConfigureActivity.class); 
        intent.setAction("android.appwidget.action.APPWIDGET_CONFIGURE");
        ConfigureActivity.this.startActivity(intent);
        return false;
    }
});
