Android_侧滑菜单的实现 _Android_

【Android_侧滑菜单的实现】知识就是力量，时间就是生命。这篇文章主要讲述Android_侧滑菜单的实现相关的知识，希望能为你提供帮助。
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:background="#FFFFFF" android:orientation="vertical"> < ImageView android:id="@+id/myfrag_head" android:layout_width="100dp" android:layout_height="100dp" android:layout_margin="10dp" android:src="https://www.songbingjia.com/android/@drawable/sor"> < /ImageView> < TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:text="小高128" android:textColor="#212" android:textSize="25dp"> < /TextView> < View android:layout_width="300dp" android:layout_height="0.1dp" android:layout_marginTop="5dp"

android:layout_width="wrap_content" android:background="#FAFAFA" android:layout_height="match_parent" android:layout_weight="1" android:gravity="center" android:text="0" android:textColor="#222" android:textSize="25dp"> < /TextView> < /LinearLayout> < LinearLayout android:layout_width="match_parent" android:layout_height="40dp" android:orientation="horizontal"> < TextView

android:layout_weight="1" android:background="#FAFAFA" android:gravity="center" android:text="粉丝" android:textColor="#222" android:textSize="20dp"> < /TextView> < /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="https://www.songbingjia.com/android/@drawable/sor"> < /ImageView> < RadioButton android:layout_marginLeft="20dp" android:layout_width="wrap_content" android:layout_height="match_parent" android:background="#FFFFFF" android:text="我的消息" android:textColor="#212" android:button="@null" android:textSize="20dp"> < /RadioButton> < ImageView

android:orientation="horizontal"> < ImageView android:layout_marginLeft="20dp" android:layout_width="25dp" android:layout_height="25dp" android:src="https://www.songbingjia.com/android/@drawable/sor"> < /ImageView> < RadioButton android:layout_marginLeft="20dp" android:layout_width="wrap_content" android:layout_height="match_parent" android:background="#FFFFFF" android:text="我的消息" android:textColor="#212" android:button="@null" android:textSize="20dp"> < /RadioButton> < ImageView android:layout_marginLeft="40dp" android:layout_width="35dp" android:layout_height="35dp" android:src="https://www.songbingjia.com/android/@drawable/jiantou" > < /ImageView> < /LinearLayout> < 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="https://www.songbingjia.com/android/@drawable/sor"> < /ImageView> < RadioButton android:layout_marginLeft="20dp" android:layout_width="wrap_content" android:layout_height="match_parent" android:background="#FFFFFF" android:text="我的消息" android:textColor="#212" android:button="@null" android:textSize="20dp"> < /RadioButton> < ImageView

android:src="https://www.songbingjia.com/android/@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="https://www.songbingjia.com/android/@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="https://www.songbingjia.com/android/@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:layout_width="match_parent" android:layout_height="0.5dp" android:layout_below="@+id/main_toplinear" android:background="#232"> < /View> < View android:layout_width="match_parent" android:layout_height="0.5dp" android:layout_above="@+id/main_radio_group" 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:layout_height="match_parent" android:layout_weight="1" 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:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/radio" android:button="@null" android:gravity="center" android:text="收支" android:textColor="#5FB1D1" android:textSize="25dp"> < /RadioButton> < RadioButton android:id="@+id/main_rd_my" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/radio" android:button="@null" android:gravity="center" android:text="社区" android:textColor="#5FB1D1" android:textSize="25dp"> < /RadioButton> < /RadioGroup> < androidx.viewpager.widget.ViewPager android:id="@+id/main_viewpager" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_above="@id/main_radio_group" android:layout_below="@+id/main_toplinear"> < /androidx.viewpager.widget.ViewPager> < /RelativeLayout> < fragment android:id="@+id/fg_left_menu" class="com.example.didida_corder.MyFragment" android:layout_width="wrap_content" 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.util.Log; import android.view.Gravity; import android.view.View; import android.widget.Adapter; 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: radioButton_inout.setChecked(true); break; case PAGE_MY: radioButton_myitem.setChecked(true); break; } } }@Override public void onCheckedChanged(RadioGroup group, int checkedId) { switch (checkedId){ case R.id.main_rd_cord:{ viewPager.setCurrentItem(PAGE_CORD); break; } case R.id.main_rd_inout:{ viewPager.setCurrentItem(PAGE_INOUT); break; } case R.id.main_rd_my:{ viewPager.setCurrentItem(PAGE_MY); break; } } }@Override public void onClick(View v) { drawerLayout.openDrawer(Gravity.LEFT); } }
