Android右侧滑动屏幕左侧出现菜单

原理使用的是自定义一个水平放心的横向滚动屏（HorizontalScrollView ）

SlidingMenu.java

package slidingmenu;

import android.content.Context;
import android.util.AttributeSet;
import android.util.DisplayMetrics;
import android.util.TypedValue;
import android.view.MotionEvent;
import android.view.ViewGroup;
import android.view.WindowManager;
import android.widget.HorizontalScrollView;
import android.widget.LinearLayout;

/**

 */

public class SlidingMenu extends HorizontalScrollView {
    private LinearLayout wapper;//整个屏幕部分
    private ViewGroup Menu;//左侧选项菜单部分
    private ViewGroup Content;//内容部分
    private int ScreenWidth;//屏幕宽度

    private int MenuWidth;//菜单宽度
    private int MenuRightPadd = 50;

    private boolean once = false;

    /**
     * 在没有使用自定义属性的情况下调用
     * @param context
     * @param attrs
     */
    public SlidingMenu(Context context, AttributeSet attrs) {
        super(context, attrs);
        WindowManager wmg = (WindowManager) context.getSystemService(context.WINDOW_SERVICE);
        DisplayMetrics displayMetrics = new DisplayMetrics();
        wmg.getDefaultDisplay().getMetrics(displayMetrics);

        /**把dp转换为px**/
        ScreenWidth = displayMetrics.widthPixels;
        MenuRightPadd = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,200,
                context.getResources().getDisplayMetrics());
    }

    /**
     * 设置子view的宽和高
     * 设置自己的宽和高
     * @param widthMeasureSpec
     * @param heightMeasureSpec
     */
    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        if(!once){
            wapper = (LinearLayout) getChildAt(0);

            Menu = (ViewGroup) wapper.getChildAt(0);
            Content = (ViewGroup) wapper.getChildAt(1);

            MenuWidth = Menu.getLayoutParams().width = ScreenWidth-MenuRightPadd;
            Content.getLayoutParams().width = ScreenWidth;
            once = true;
        }
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

    /**
     * 设置偏移量 将Menu隐藏
     * @param changed
     * @param l
     * @param t
     * @param r
     * @param b
     */
    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b) {
        super.onLayout(changed, l, t, r, b);
        if(!changed){
            this.scrollTo(MenuWidth,0);
        }
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        int action = ev.getAction();
        switch (action){
            case MotionEvent.ACTION_UP://当用户抬起手指时
                //scrollx是隐藏在左边的内容宽度 也就是没有显示的宽度
                int scrollX = getScrollX();
                if(scrollX>=MenuWidth/2){
                    this.smoothScrollTo(MenuWidth,0);
                }else{
                    this.smoothScrollTo(0,0);
                }
                break;
        }
        return super.onTouchEvent(ev);
    }
}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.hp.tab.MainActivity">
    
    <!--包名.文件名-->
    <slidingmenu.SlidingMenu
        android:scrollbars="none"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <LinearLayout

            android:orientation="horizontal">
            <!--<include  layout="@layout/left_menu"/>-->
            <FrameLayout
                android:layout_width="100dp"
                android:id="@+id/list"
                android:layout_height="match_parent">
            </FrameLayout>
            <FrameLayout
                android:id="@+id/content"

                android:layout_height="match_parent">
            </FrameLayout>
<!--            <LinearLayout

                android:layout_height="match_parent">

            </LinearLayout>-->
        </LinearLayout>
    </slidingmenu.SlidingMenu>

</RelativeLayout>

接下来使用的是两个碎片

fragment_icon.xml这是左侧菜单栏部分

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

item_list.xml这个布局文件用于上面碎片中的列表集合，用于显示图标

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <ImageView
        android:src="@mipmap/o1"
        android:id="@+id/imgv"
        android:layout_width="60dp"
        android:layout_margin="10dp"
        android:layout_height="wrap_content" />
</RelativeLayout>

fragment_settinglist.xml这是右侧内容部分的碎片

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
    android:layout_height="match_parent">
    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_margin="10dp"
        android:background="@android:color/white"
        android:layout_height="fill_parent">
            <TextView
                android:id="@+id/tv"
                android:textSize="18sp"
                android:layout_alignParentLeft="true"
                android:layout_centerVertical="true"
                android:layout_marginLeft="10dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />
    </RelativeLayout>
</LinearLayout>

接下来是碎片的java文件

iconFragment.java菜单碎片的java文件

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        return view;
    }


    public void initview(){
        listView = (ListView) view.findViewById(R.id.settingicon);
        if(settincon!=null){
            listView.setAdapter(baseAdapter);
        }
    }

    BaseAdapter baseAdapter = new BaseAdapter() {

        }

        @Override

            ImageView imageView = (ImageView) view.findViewById(R.id.imgv);
            imageView.setImageResource(settincon[i]);
            return  view;
        }
    };
}

SettingListFragment.java 内容碎片的java文件

import android.app.Fragment;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

/**

public class SettingListFragment extends Fragment {
    private View view;
    private TextView textView;

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
    }

    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {
       view = inflater.inflate(R.layout.fragment_settinglist,container,false);
       if(view!=null){
           initView();
       }
        SetText(((MainActivity)getActivity()).getText()[0]);
       return view;
    }
    public void initView(){
        textView = view.findViewById(R.id.tv);
    }
    public void SetText(String text){
        textView.setText(text);
    }
}

MainActivity.java

package com.example.hp.tab;

import android.app.Activity;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.Window;

public class MainActivity extends Activity {
    FragmentTransaction fragmentTransaction;
    private  String[] text = {"aaa","bbb","ccc","ddd"};
    private int[] icon = {R.mipmap.o1,R.mipmap.o2,R.mipmap.o3,R.mipmap.o4};
    public int[] getIcon() {
        return icon;
    }
    public String[] getText() {
        return text;
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);
        iconFragment iconFragment = new iconFragment();
        SettingListFragment settingListFragment = new SettingListFragment();

        fragmentTransaction = getFragmentManager().beginTransaction();

        fragmentTransaction.replace(R.id.list,iconFragment);
        fragmentTransaction.replace(R.id.content,settingListFragment);

        fragmentTransaction.commit();
    }
}

以上全部内容可以全部复制过去直接使用
