效果图

实现思维

  1. 首先要处理管理好需要导入的数据,我们这里创建class来处理这些数据并且便于管理它们。
  2. 创建一个主activity的布局,里面需要一个ListView控件。
  3. 创建一个class继承GirdView,并且重写它。我们需要取消GirdView布局的滚动,让它显示全部内容
  4. 创建一个GirdView的布局,里面导入我们重写好GirdView控件。
  5. 创建GirdView布局里面小图标的布局。
  6. 创建一个class继承GirdView的适配器,我们需要重写GirdView适配器class
  7. 创建ListView适配器使用的数据集合的单例class。
  8. 创建一个class继承ListView的适配器,我们需要重写ListView适配器class
  9. 在主activity里实例ListView,处理数据,数据导入适配器,ListView设置适配器

代码部分

1.首先要处理管理好需要导入的数据,我们这里创建class来处理这些数据并且便于管理它们。

这里涉及隐私我只贴出部分代码做参考

package com.example.lenovo.mydemoapp.myMoreOptions;

import com.example.lenovo.mydemoapp.R;

/**
 * Created by lenovo on 2018/5/22.
 */

/*
 更多选项列表的数据存放class
 */
public class MoreOptionsData {
    //沟通组
    private static final String mPhoneTitlem_Title_Text = "沟通";
    private static final String [] mPhoneTitlem_Content_Text = {"电话","群聊","私聊","倾听","录音","拍照"};
    //得到沟通组数据
    public static int[] getmPhoneTitlemContent_Image() {
        return mPhoneTitlem_Content_Image;
    }

    public static String[] getmPhoneTitlemContent_Text() {
        return mPhoneTitlem_Content_Text;
    }

    public static String getmPhoneTitlem_Title_Text() {
        return mPhoneTitlem_Title_Text;
    }

    //得到运动组数据
    public static int[] getmMovementTitlemContent_Image() {
        return mMovementTitlem_Content_Image;
    }

    public static String[] getmMovementTitlemContent_Text() {
        return mMovementTitlem_Content_Text;
    }

    public static String getmMovementTitlem_Title_Text() {
        return mMovementTitlem_Title_Text;
    }

    //得到设置组数据
    public static int[] getmSettingsTitlemContent_Image() {
        return mSettingsTitlem_Content_Image;
    }

    public static String[] getmSettingsTitlemContent_Text() {
        return mSettingsTitlem_Content_Text;
    }

    public static String getmSettingsTitlem_Title_Text() {
        return mSettingsTitlem_Title_Text;
    }

    //得到其他组数据
    public static int[] getmOtherTitlemContent_Image() {
        return mOtherTitlem_Content_Image;
    }

    public static String[] getmOtherTitlemContent_Text() {
        return mOtherTitlem_Content_Text;
    }

    public static String getmOtherTitlem_Title_Text() {
        return mOtherTitlem_Title_Text;
    }
    //得到四组数据的数组
    public static String[] getTitle_Text_Attrs(){
        return new String[] {mPhoneTitlem_Title_Text,mMovementTitlem_Title_Text,mSettingsTitlem_Title_Text,mOtherTitlem_Title_Text};
    }
    public static String[][] getContent_Text_Attrs(){
        return new String[][] {mPhoneTitlem_Content_Text,mMovementTitlem_Content_Text,mSettingsTitlem_Content_Text,mOtherTitlem_Content_Text};
    }
    public static int[][] getContent_Image_Attrs(){
        return new int[][] {mPhoneTitlem_Content_Image,mMovementTitlem_Content_Image,mSettingsTitlem_Content_Image,mOtherTitlem_Content_Image};
    }
}

2.创建一个主activity的布局,里面需要一个ListView控件。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.lenovo.mydemoapp.MoreOptions"
    >
    <com.example.lenovo.mydemoapp.myLayout.TitleLayout
        app:titleNameText="显示标题"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    </com.example.lenovo.mydemoapp.myLayout.TitleLayout>
    <ListView
        android:id="@+id/MoreOptions_ListView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="20dp"
        android:dividerHeight="20dp"
        android:divider="@color/colorWhite">
    </ListView>

</LinearLayout>

3.创建一个class继承GirdView,并且重写它。我们需要取消GirdView布局的滚动,让它显示全部内容

package com.example.lenovo.mydemoapp.myMoreOptions;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.GridView;

/**
 * Created by lenovo on 2018/5/23.
 */

public class NoScrollGridView extends GridView {
    public NoScrollGridView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public NoScrollGridView(Context context) {
        super(context);
    }

    public NoScrollGridView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }


    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        //核心在此
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 3,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }
}


4.创建一个GirdView的布局,里面导入我们重写好GirdView控件。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/input_box_background">
    <TextView
        android:id="@+id/MoreOptions_GridView_TitleName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="标题名称"
        android:textSize="@dimen/BigTextSize"
        android:textColor="@color/colorBlue"/>
    <com.example.lenovo.mydemoapp.myMoreOptions.NoScrollGridView
        android:id="@+id/MoreOptions_GridView"
        android:numColumns="3"
        android:stretchMode="columnWidth"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:horizontalSpacing="20dp"
        android:verticalSpacing="20dp"
        android:layout_marginTop="20dp">
    </com.example.lenovo.mydemoapp.myMoreOptions.NoScrollGridView>

</LinearLayout>

5.创建GirdView布局里面小图标的布局。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="5dp">
    <ImageView
        android:id="@+id/more_options_grid_view_subclass_ImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:src="@drawable/ic_funciton_shutdown"/>
    <TextView
        android:id="@+id/more_options_grid_view_subclass_TextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="图标名称"
        android:textColor="@color/colorBlue"
        android:textSize="@dimen/BigTextSize"
        android:layout_marginTop="15dp"/>

</LinearLayout>

6.创建一个class继承GirdView的适配器,我们需要重写GirdView适配器class

package com.example.lenovo.mydemoapp.myMoreOptions;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import com.example.lenovo.mydemoapp.R;
import com.example.lenovo.mydemoapp.myDeviceList.DeivceListAdapter;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by lenovo on 2018/5/22.
 */
/*
GridView的适配器class
 */
public class MoreOptionsGridViewAdapter extends BaseAdapter {
    //创建一个数据集合,将传入的数组转化成List集合
    private List<DataList> mdataLists = new ArrayList<DataList>();
    //将传入的Context设置为全局变量
    private Context mContext;
    public MoreOptionsGridViewAdapter(Context context){
        super();
        this.mContext = context;
    }
    @Override
    public int getCount() {
        return mdataLists.size();
    }

    @Override
    public Object getItem(int position) {
        return mdataLists.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }
    /*
    自写一个数据导入的方法,在方法将在ListView的适配器class里调用,
    因为我们将GridView适配器数据导入放到了ListView适配器class中
     */
    public void setmList(String[] name,int[] image){
        for (int i=0;i<name.length;i++){
            //实例化一个单例内部class导入数据
            DataList dataList = new DataList(name[i],image[i]);
            //添加到集合中
            mdataLists.add(dataList);
        }
    }

    /*
    重写getView方法,获得控件单例,添加单例数据,缓存单例
     */
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        //用于缓存的控件的class,目的是不让一个控件的获取需要反复使用findViewById,可以优化滚动布局速度
        MoreOptionsViewHolder moreOptionsViewHolder;
        //如果当前的一个的View是空的,那就重新findViewById获取它。
        if (convertView == null){
            convertView = LayoutInflater.from(mContext).inflate(R.layout.more_options_grid_view_subclass,null);
            moreOptionsViewHolder = new MoreOptionsViewHolder();
            moreOptionsViewHolder.name = (TextView)convertView.findViewById(R.id.more_options_grid_view_subclass_TextView);
            moreOptionsViewHolder.image = (ImageView)convertView.findViewById(R.id.more_options_grid_view_subclass_ImageView);
            convertView.setTag(moreOptionsViewHolder);
        }else { //如果有这个View,那就继续使用已经找到的子类控件实例
            moreOptionsViewHolder = (MoreOptionsViewHolder)convertView.getTag();
        }
        //根据当前位置获取List数据集合中的单例
        DataList dataList = mdataLists.get(position);
        //配置控件单例对应的List单例数据
        moreOptionsViewHolder.image.setImageResource(dataList.getImage());
        moreOptionsViewHolder.name.setText(dataList.getName());
        return convertView;
    }
    /*
    写一个数据存放的单例内部class
     */
    class DataList{
        private String name;
        private int image;
        public DataList(String name,int image){
            this.name = name;
            this.image = image;
        }
        public int getImage() {
            return image;
        }

        public String getName() {
            return name;
        }
    }
    /*
    控件缓存
     */
    class MoreOptionsViewHolder {
        public TextView name;
        public ImageView image;
    }
}

7.创建ListView适配器使用的数据集合的单例class。

package com.example.lenovo.mydemoapp.myMoreOptions;

import android.widget.GridView;

/**
 * Created by lenovo on 2018/5/23.
 */

public class MoreOptionsDataLineViewData {
    private GridView gridView;
    private String TitleName ;
    public MoreOptionsDataLineViewData(String titleName,GridView gridView){
        this.TitleName = titleName;
        this.gridView = gridView;
    }
    public String getTitleName() {
        return TitleName;
    }

    public GridView getGridView() {
        return gridView;
    }
}

8.创建一个class继承ListView的适配器,我们需要重写ListView适配器class

package com.example.lenovo.mydemoapp.myMoreOptions;

import android.content.Context;
import android.support.annotation.LayoutRes;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.TextView;

import com.example.lenovo.mydemoapp.R;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by lenovo on 2018/5/23.
 */
/*
ListView的适配器类
 */
public class MoreOptionsListViewAdapter extends ArrayAdapter<MoreOptionsDataLineViewData>{
    List<MoreOptionsDataLineViewData> mlineViewDatas;
    //布局ID
    int resourceId;
    public MoreOptionsListViewAdapter(@NonNull Context context, @LayoutRes int resource, @NonNull List<MoreOptionsDataLineViewData> objects) {
        super(context, resource, objects);
        resourceId = resource;
    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        MoreOptionsDataLineViewData moreOptionsDataLineViewData = getItem(position);
        View view = LayoutInflater.from(getContext()).inflate(resourceId,parent,false);
        TextView textView = (TextView)view.findViewById(R.id.MoreOptions_GridView_TitleName);
        GridView gridView = (GridView)view.findViewById(R.id.MoreOptions_GridView);
        //导入标题栏数据
        textView.setText(moreOptionsDataLineViewData.getTitleName());
        //实例化一个GridView的适配器class
        MoreOptionsGridViewAdapter moreOptionsGridViewAdapter = new MoreOptionsGridViewAdapter(view.getContext());
        //添加适配器的数据
        moreOptionsGridViewAdapter.setmList(new MoreOptionsData().getContent_Text_Attrs()[position]
                ,new MoreOptionsData().getContent_Image_Attrs()[position]);
        //将gridView设置适配器
        gridView.setAdapter(moreOptionsGridViewAdapter);
        return view;
    }
}

9.在主activity里实例ListView,处理数据,数据导入适配器,ListView设置适配器

package com.example.lenovo.mydemoapp;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.GridView;
import android.widget.ListView;

import com.example.lenovo.mydemoapp.myMoreOptions.MoreOptionsData;
import com.example.lenovo.mydemoapp.myMoreOptions.MoreOptionsDataLineViewData;
import com.example.lenovo.mydemoapp.myMoreOptions.MoreOptionsGridViewAdapter;
import com.example.lenovo.mydemoapp.myMoreOptions.MoreOptionsListViewAdapter;

import java.util.ArrayList;
import java.util.List;

public class MoreOptions extends AppCompatActivity {
    //实例数据class
    private MoreOptionsData mMoreOptionsData = new MoreOptionsData();
    //创建listView使用的数据集合
    private List<MoreOptionsDataLineViewData>  lineViewDatas = new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_more_options);
        ListView listView = (ListView)findViewById(R.id.MoreOptions_ListView);
        //根据标题名称数组长度创建GridView的数量
        for (int i=0;i<mMoreOptionsData.getTitle_Text_Attrs().length;i++){
            //创建GridView的实例,注意这里的GridView我们并没有设置适配器,而是直接添加到List数据集合中,一起传入ListView的适配器Class里面。
            //我们将在ListView的适配器class里面,在给GridView的单例设置GridView的适配器class
            GridView gridView = (GridView)findViewById(R.id.MoreOptions_GridView);
            //给集合的单例添加数据: 数据为一个标题名称,一个GridView实例
            MoreOptionsDataLineViewData lineViewData = new MoreOptionsDataLineViewData(mMoreOptionsData.getTitle_Text_Attrs()[i],gridView);
            ///将单例数据导入listView使用的数据集合中
            lineViewDatas.add(lineViewData);
        }
        //给ListView的适配器导入数据
        MoreOptionsListViewAdapter moreOptionsListViewAdapter = new MoreOptionsListViewAdapter(MoreOptions.this,R.layout.more_options_grid_view,lineViewDatas);
        //给ListView设置适配器
        listView.setAdapter(moreOptionsListViewAdapter);
    }
}
