android 开发 实现一个ListView套嵌GirdView的滚动布局

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);
}
}
