java-Android中偏好设置活动的onclick侦听器

我遵循this documentations创建一个设置页面.我根据文档创建了两个java类：

SettingsFragment.java：

public static class SettingsFragment extends PreferenceFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Load the preferences from an XML resource
        addPreferencesFromResource(R.xml.preferences);
    }
    ...
}

SettingsActivity.java

public class SettingsActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Display the fragment as the main content.
        getFragmentManager().beginTransaction()
                .replace(android.R.id.content, new SettingsFragment())
                .commit();
    }
}

在首选项中,我有一个带有键premium_support的项目,我想为其创建一个点击监听器.

 <CheckBoxPreference
        android:key="@string/premium_support"
        android:title="Premium Support"
        android:summary="Purchase premium support"
        android:defaultValue="false" />

我无法在该片段中创建点击监听器,因为我在SettingsActivity中有我的应用内结算代码.我尝试了this answer,但似乎findPreference仅用于preferencefragment.

任何想法如何在SettingsActivity中实现点击侦听器？

解决方法:

在SettingsActivity的onCreate()方法中：

Preference preference = findPreference("prefs_key");
preference.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
   @Override
   public boolean onPreferenceClick(Preference preference) {
       Toast.makeText(SettingsActivity.this, "Clicked", Toast.LENGTH_SHORT).show();
       return true;
   }
});
