按钮添加到PreferenceFragment(Add buttons to PreferenceF

我想添加几个按钮来我的喜好屏幕底部设置默认值和恢复默认设置。 这个答案不包括如何做到这一点使用PreferenceFragment。 什么是做到这一点的推荐方式。

活动加载的偏好片段：

public class SettingsActivity extends Activity {

    @Override
    public void onCreate( Bundle savedInstanceState) {

        super.onCreate( savedInstanceState);

        // load up the preferences fragment
        getFragmentManager().beginTransaction().replace( android.R.id.content, new PrefsSettingsFragment()).commit();
    }
}

PreferenceFragment实现：

public class PrefsSettingsFragment extends PreferenceFragment {

    @Override
    public void onCreate( Bundle savedInstanceState) {

        super.onCreate( savedInstanceState);  

        addPreferencesFromResource( R.xml.preferences);             
    }       
}

的preferences.xml：

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

    <EditTextPreference android:key="edit_text_preference_server_address" android:title="@string/preference_server_address"/>
    <SwitchPreference android:key="switch_preference_bat" android:title="@string/preference_bat"/>
    <SwitchPreference android:key="switch_preference_comm" android:title="@string/preference_comm"/>
    <SwitchPreference android:key="switch_preference_dev_mode" android:title="@string/preference_dev_mode" android:defaultValue="true"/>

</PreferenceScreen>

Answer 1:

我遇到同样的问题，我找到了一种方法来处理这个问题。

覆盖方法onCreateView在PreferenceFragment，使用给定的LayoutInfalter通过参数来创建自己的视图，并返回这一观点。

这是我的代码。 我希望这可以帮助

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub

        View v = inflater.inflate(R.layout.set_alarm, null);

        Button save = (Button)v.findViewById(R.id.save);
        Button revert = (Button)v.findViewById(R.id.revert);
        Button delete = (Button)v.findViewById(R.id.delete);

        save.setOnClickListener(this);
        revert.setOnClickListener(this);
        delete.setOnClickListener(this);

        if(mId == -1){
            delete.setEnabled(false);
        }

        return v;
    }

Answer 2:

我修改了以前的帖子一点点，这样按钮将在视图的底部得到重视。

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        LinearLayout v = (LinearLayout) super.onCreateView(inflater, container, savedInstanceState);

        Button btn = new Button(getActivity().getApplicationContext());
        btn.setText("Button on Bottom");

        v.addView(btn);
        btn.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
            }
        });

        return v;
    }

Answer 3:

刚创建的设置活动包含ID为@android列表视图自己的布局：ID /名单

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/root"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <FrameLayout
        android:id="@+id/fragment"
        android:layout_weight="1"
        android:layout_width="match_parent"
        android:layout_height="0dp">
        <ListView
            android:id="@android:id/list"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    </FrameLayout>

    <Button
        android:id="@+id/button"
        android:text="Save"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

然后在活动类设置的内容视图中添加偏好片段之前

public class SettingsActivity extends Activity {

    @Override
    public void onCreate( Bundle savedInstanceState) {    
        super.onCreate( savedInstanceState);
        setContentView(R.layout.settings_activity)

        // load up the preferences fragment
        getFragmentManager().beginTransaction().replace( android.R.id.content, new PrefsSettingsFragment()).commit();
    }
}

Answer 4:

您可以尝试这个

@Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            LinearLayout v = (LinearLayout) super.onCreateView(inflater, container, savedInstanceState);

            Button SendLogbtn = new Button(getActivity().getApplicationContext());
            SendLogbtn.setText("send log file");

            LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
                    LayoutParams.WRAP_CONTENT);

            params.setMargins(100, 0, 0, 500);
            SendLogbtn.setLayoutParams(params);

            v.addView(SendLogbtn);

            SendLogbtn.setOnClickListener(new View.OnClickListener() {

                public void onClick(View v) {

                    // do your code 

                }
            });

            return v;
        }
