Android 自定义底部公用菜单

注释:此案例主要展示自定义底部菜单，一处封装处处调用。使用起来相当方便

一、初始的Activity

package com.example.myapi.buttommenu;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

import com.example.myapi.R;
import com.example.myapi.buttommenu.MenuUtils.MeunOnClickListener;

public class Menu1Activity extends Activity implements MeunOnClickListener,OnClickListener{
    private MenuUtils menuUtils;
    private Button btn_two;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.menu1);
        menuUtils = (MenuUtils)findViewById(R.id.menu_utils);
        menuUtils.setMenuListener(this);
        btn_two = (Button)findViewById(R.id.btn_two);
        btn_two.setOnClickListener(this);
    }

    @Override
    public void menuOne() {
        Toast.makeText(this, "您点击了菜单一", Toast.LENGTH_LONG).show();
    }

    @Override
    public void menuTwo() {
        Toast.makeText(this, "您点击了菜单二", Toast.LENGTH_LONG).show();
    }

    @Override
    public void menuThree() {
        Toast.makeText(this, "您点击了菜单三", Toast.LENGTH_LONG).show();
    }

    @Override
    public void menuFour() {
        Toast.makeText(this, "您点击了菜单四", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onClick(View v) {
        switch(v.getId()){
        case R.id.btn_two:
            Intent intent = new Intent();
            intent.setClass(this, Menu2Activity.class);
            startActivity(intent);
            break;
        }
    }

}

第二个Activity

package com.example.myapi.buttommenu;

import com.example.myapi.R;
import com.example.myapi.buttommenu.MenuUtils.MeunOnClickListener;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast;

public class Menu2Activity extends Activity implements MeunOnClickListener{
    private MenuUtils menuUtils;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.menu2);
        menuUtils = (MenuUtils)findViewById(R.id.menu_utils);
        menuUtils.setMenuListener(this);
    }

    @Override
    public void menuOne() {
        Toast.makeText(this, "您点击了菜单一", Toast.LENGTH_LONG).show();
    }

    @Override
    public void menuTwo() {
        Toast.makeText(this, "您点击了菜单二", Toast.LENGTH_LONG).show();
    }

    @Override
    public void menuThree() {
        Toast.makeText(this, "您点击了菜单三", Toast.LENGTH_LONG).show();
    }

    @Override
    public void menuFour() {
        Toast.makeText(this, "您点击了菜单四", Toast.LENGTH_LONG).show();
    }
}

自定义Menu

package com.example.myapi.buttommenu;

import android.content.Context;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.LinearLayout;

import com.example.myapi.R;

/**
 * 菜单工具类
 * @author
 *  *
 */
public class MenuUtils extends LinearLayout implements OnClickListener{
    private Button btn_1;
    private Button btn_2;
    private Button btn_3;
    private Button btn_4;
    private Context context;
    private MeunOnClickListener listener;
    public MenuUtils(Context context) {
        super(context);
        this.context = context;
        initView(context);
    }
    public MenuUtils(Context context, AttributeSet attrs) {
        super(context, attrs);
        initView(context);
    }
    private void initView(Context context){
        LinearLayout menuView = (LinearLayout)LayoutInflater.from(context).inflate(com.example.myapi.R.layout.menutuils, null);
        addView(menuView);
        btn_1 = (Button)menuView.findViewById(R.id.btn_1);
        btn_2 = (Button)menuView.findViewById(R.id.btn_2);
        btn_3 = (Button)menuView.findViewById(R.id.btn_3);
        btn_4 = (Button)menuView.findViewById(R.id.btn_4);
        btn_1.setOnClickListener(this);
        btn_2.setOnClickListener(this);
        btn_3.setOnClickListener(this);
        btn_4.setOnClickListener(this);
    }
    public void setMenuListener(MeunOnClickListener listener){
        this.listener = listener;
    }
    public interface MeunOnClickListener{
        public void menuOne();
        public void menuTwo();
        public void menuThree();
        public void menuFour();
    }
    @Override
    public void onClick(View v) {
        switch(v.getId()){
        case R.id.btn_1:
            listener.menuOne();
            break;
        case R.id.btn_2:
            listener.menuTwo();
            break;
        case R.id.btn_3:
            listener.menuThree();
            break;
        case R.id.btn_4:
            listener.menuFour();
            break;
        }
    }

}

一下是布局文件

<?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"
    android:orientation="vertical" >
       <com.example.myapi.buttommenu.MenuUtils
        android:id="@+id/menu_utils"
        android:layout_width="fill_parent"
        android:layout_height="60dp"
        />
    <Button
        android:id="@+id/btn_two"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="跳转到第二个界面"/>
</LinearLayout>

<?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"
    android:orientation="vertical" >
    <com.example.myapi.buttommenu.MenuUtils
        android:id="@+id/menu_utils"
        android:layout_width="fill_parent"
        android:layout_height="60dp"
        />

</LinearLayout>

<?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"
    android:orientation="vertical" >
    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <Button
            android:id="@+id/btn_1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center"
            android:text="菜单一"/>
        <Button
            android:id="@+id/btn_2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:layout_weight="1"
            android:text="菜单二"/>
        <Button
            android:id="@+id/btn_3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:layout_weight="1"
            android:text="菜单三"/>
        <Button
            android:id="@+id/btn_4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:layout_weight="1"
            android:text="菜单四"/>
    </LinearLayout>

</LinearLayout>
