Android_侧滑菜单的实现

1、创建侧滑菜单Fragment

 

package com.example.didida_corder;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;

import java.util.zip.Inflater;

public class MyFragment extends Fragment implements View.OnClickListener {
    private TextView tv_like, tv_likeme, tv_depatch;
    private int like, likeme, depatch;
    private boolean flag = false;

    public MyFragment() {

    }

    public MyFragment(int like, int likeme, int depatch) {
        this.like = like;
        this.likeme = likeme;
        this.depatch = depatch;
        flag = true;
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        Inflater inflater1 = new Inflater();
        View view = inflater.inflate(R.layout.layout_myfragment, null, false);
        tv_like = view.findViewById(R.id.myfrag_likeone);
        tv_likeme = view.findViewById(R.id.myfrag_likeme);
        tv_depatch = view.findViewById(R.id.myfrag_patch);
        if (flag) {
            tv_like.setText(like);
            tv_likeme.setText(likeme);
            tv_depatch.setText(depatch);
        }
        return view;
    }

    @Override
    public void onClick(View v) {

    }
}

　　

2、编写其layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="270dp"
    android:layout_height="match_parent"

    android:orientation="vertical">

    <ImageView
        android:id="@+id/myfrag_head"

        android:layout_margin="10dp"
        android:src="@drawable/sor"></ImageView>

    <TextView

            android:text="0"
            android:textColor="#222"
            android:textSize="25dp"></TextView>
    </LinearLayout>

    <LinearLayout

    </LinearLayout>

    <View
        android:layout_width="300dp"
        android:layout_height="0.1dp"
        android:background="#212"></View>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:gravity="center_vertical"
        android:layout_weight="1"
        android:orientation="horizontal">

        <ImageView
            android:layout_marginLeft="20dp"
            android:layout_width="25dp"
            android:layout_height="25dp"
            android:src="@drawable/sor"></ImageView>

            android:button="@null"
            android:textSize="20dp"></RadioButton>

        <ImageView

            android:layout_height="25dp"
            android:src="@drawable/sor"></ImageView>

        <RadioButton
            android:layout_marginLeft="20dp"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"

        android:layout_marginTop="20dp"
        android:gravity="center_vertical"
        android:layout_weight="1"
        android:orientation="horizontal">

        <ImageView
            android:layout_marginLeft="20dp"
            android:layout_width="25dp"
            android:layout_height="25dp"

            android:src="@drawable/jiantou"
            ></ImageView>
    </LinearLayout>
</LinearLayout>

　　

3、activity的中布局文件要以DrawerLayout包裹，第一个控件是主屏幕。

 

<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_drawlayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#FFFFFF"
        android:orientation="horizontal"
        tools:context=".MainActivity">
        <LinearLayout
            android:id="@+id/main_toplinear"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:background="#FFFFFF"
            android:gravity="center"
            android:orientation="horizontal">

            <ImageView
                android:id="@+id/main_leftmenu"
                android:layout_width="35dp"
                android:layout_height="35dp"
                android:layout_marginLeft="20dp"
                android:src="@drawable/sanxian"></ImageView>

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="70dp"
                android:background="#FFFFFF"
                android:gravity="center">

                <ImageView
                    android:layout_width="60dp"
                    android:layout_height="60dp"
                    android:layout_margin="5dp"
                    android:src="@drawable/icon"></ImageView>

                <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="滴滴嗒小账本"
                    android:textColor="#5FB1D1"
                    android:textSize="25dp"></TextView>
            </LinearLayout>

            <ImageView
                android:layout_width="35dp"
                android:layout_height="35dp"
                android:layout_marginRight="20dp"></ImageView>
        </LinearLayout>

        <View

            android:background="#232"></View>

        <View
            android:layout_width="match_parent"

            android:background="#232"></View>

        <RadioGroup
            android:id="@+id/main_radio_group"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:layout_alignParentBottom="true"
            android:background="#EDDEF7"
            android:gravity="center"
            android:orientation="horizontal">

            <RadioButton
                android:id="@+id/main_rd_cord"
                android:layout_width="wrap_content"

                android:background="@drawable/radio"
                android:button="@null"
                android:gravity="center"
                android:text="记录"
                android:textColor="#5FB1D1"
                android:textSize="25dp"></RadioButton>

            <RadioButton
                android:id="@+id/main_rd_inout"
                android:layout_width="5dp"

                android:text="收支"
                android:textColor="#5FB1D1"
                android:textSize="25dp"></RadioButton>

            <RadioButton
                android:id="@+id/main_rd_my"

                android:layout_height="match_parent"
                android:layout_weight="1"
                android:background="@drawable/radio"
                android:button="@null"

        </RadioGroup>

        <androidx.viewpager.widget.ViewPager

        android:layout_height="match_parent"
        android:layout_gravity="start"
        tools:layout="@layout/layout_myfragment"
        ></fragment>
</androidx.drawerlayout.widget.DrawerLayout>

 

　　

 

4、通过openDrawer和onclick实现点击按钮打开侧滑菜单

 

package com.example.didida_corder;

import androidx.appcompat.app.AppCompatActivity;
import androidx.drawerlayout.widget.DrawerLayout;
import androidx.fragment.app.FragmentManager;
import androidx.viewpager.widget.ViewPager;

import android.os.Bundle;

import android.view.Gravity;
import android.view.View;

import android.widget.ImageView;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity implements ViewPager.OnPageChangeListener, RadioGroup.OnCheckedChangeListener, View.OnClickListener {
   
    private ViewPager viewPager;
    private TextView textView;
    private ImageView my_right_menu;
    private RadioGroup radioGroup;
    private DrawerLayout drawerLayout;
    private RadioButton radioButton_crod;
    private RadioButton radioButton_inout;
    private RadioButton radioButton_myitem;
    private int PAGE_NUM = 3;
    private final int PAGE_CORD = 0;
    private final int PAGE_INOUT = 1;
    private final int PAGE_MY = 2;
    private MyFragPageAdapter myFragPageAdapter;
    private MyFragment myFragment;
    private FragmentManager fragmentManager;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        fragmentManager=getSupportFragmentManager();
        myFragPageAdapter=new MyFragPageAdapter(getSupportFragmentManager());
        bindViews();
        radioButton_crod.setChecked(true);
        initLeftMenu();
    }
    private void bindViews(){
        radioButton_crod=findViewById(R.id.main_rd_cord);
        radioButton_inout=findViewById(R.id.main_rd_inout);
        radioButton_myitem=findViewById(R.id.main_rd_my);
        radioGroup=findViewById(R.id.main_radio_group);
        radioGroup.setOnCheckedChangeListener(this);
        viewPager= findViewById(R.id.main_viewpager);
        viewPager.setAdapter(myFragPageAdapter);
        viewPager.addOnPageChangeListener(this);
        viewPager.setCurrentItem(0);
        drawerLayout=findViewById(R.id.main_drawlayout);
        myFragment= (MyFragment) fragmentManager.findFragmentById(R.id.fg_left_menu);
    }

    public void initLeftMenu(){
        my_right_menu=findViewById(R.id.main_leftmenu);
        my_right_menu.setOnClickListener(this);
    }
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {

    }

    @Override
    public void onPageScrollStateChanged(int state) {
       if (state==2){
           switch (viewPager.getCurrentItem()){
               case PAGE_CORD:
                   radioButton_crod.setChecked(true);
                   break;
               case PAGE_INOUT:
