java - 带按钮的复选框首选项

Question

我在这里找到了问题的答案: CheckBoxPreference with additional Button?但我真的不明白该怎么做。可能是因为我不太懂英语。我需要放入 ChekBoksPreferens 按钮。谁能举例说明如何做到这一点。

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 ????
        }
    }

使用以下代码在单击按钮时使用复选框验证将值保存在共享首选项中。 私有(private) SharedPreferences.Editor 登录PrefsEditor； 私有(private) SharedPreferences 登录首选项；//onCreate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();

                        }

}
