带按钮的复选框首选项

Question

我在这里找到了问题的答案：带有附加按钮的复选框首选项？但我真的不知道该怎么做。可能是因为我不太懂英语。我需要输入ChekBoksPreferens按钮。有人能举个例子吗？

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.drawable.Drawable;
import android.preference.CheckBoxPreference;
import android.preference.Preference;
import android.util.AttributeSet;
import android.view.View;
import android.widget.ImageView;
    public class IconPreferenceScreen extends CheckBoxPreference {
        private Drawable mIcon;
        public IconPreferenceScreen(Context context, AttributeSet attrs) {
            this(context, attrs, 0);
        }
        public IconPreferenceScreen(Context context, AttributeSet attrs, int defStyle) {
            super(context, attrs, defStyle);
            setLayoutResource(R.layout.preference_icon);
            TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.IconPreferenceScreen, defStyle, 0);
            mIcon = a.getDrawable(R.styleable.IconPreferenceScreen_myIcon);
        }
        @Override
        public void onBindView(View view) {
            super.onBindView(view);
            ImageView imageView = (ImageView) view.findViewById(R.id.icon);
            if (imageView != null && mIcon != null) {
                imageView.getLayoutParams().height = 150;
                imageView.getLayoutParams().width = 150;
                imageView.setImageDrawable(mIcon);
            }
        }
        public void setIcon(Drawable icon) {
            if ((icon == null && mIcon != null) || (icon != null && !icon.equals(mIcon))) {
                mIcon = icon;
                notifyChanged();
            }
        }
        public Drawable getIcon() {
            return mIcon;
        }
        public class CheckBoxPreferenceSubclassWithButton{
            ???? what next ????
        }
    }

使用以下代码将值保存在sharedpreferences中，使用复选框验证并单击按钮。private SharedPreferences.Editor loginPreferencesEditor；private SharedPreferences loginPreferences；//创建之后

 CheckBox  saveCheckBox = (CheckBox) findViewById(R.id.test);
    loginPreferences = getSharedPreferences("loginPrefs", MODE_PRIVATE);
        loginPrefsEditor = loginPreferences.edit();
// on button click

@Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch (v.getId()) {
        case R.id.sunbmit:
if (saveCheckBox.isChecked()) {

                            loginPrefsEditor.putBoolean("saveLogin", true);
                            loginPrefsEditor
                                    .putString("username", "value");
                            loginPrefsEditor
                                    .putString("password", "value");
                            loginPrefsEditor.commit();
                        } else {
                            loginPrefsEditor.clear();
                            loginPrefsEditor.commit();
                        }
}

    }
