Android仿微信底部菜单

            今天终于把公司的界面原型做完了，哈哈，提前完成正好趁现在有时间更新下最近学到的一些特殊效果。其中这个仿微信的底部菜单，真的要感谢家辉兄弟，我才得以解决。首先看一下实现后效果。

     

    就下面的那个底部栏，下面看一下实现代码吧！

    首先是布局main.xml:

 

<?xml version="1.0" encoding="UTF-8"?>
<TabHost android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"
  xmlns:android="http://schemas.android.com/apk/res/android">
    <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent">
        <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="0.0dip" android:layout_weight="1.0" />
        <TabWidget android:id="@android:id/tabs" android:visibility="gone" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="0.0" />

        <LinearLayout android:gravity="bottom" android:layout_gravity="bottom" android:orientation="horizontal" android:id="@+id/main_tab_group" android:background="@drawable/bottom1" android:paddingTop="2.0dip" android:layout_width="fill_parent" android:layout_height="wrap_content">
            <FrameLayout android:background="@null" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0">
                <LinearLayout android:id="@+id/main_layout_addExam" android:gravity="bottom|center" android:layout_width="fill_parent" android:layout_height="fill_parent">
                    <RadioButton android:id="@+id/main_tab_addExam" android:checked="true" android:text="添加考试" android:drawableTop="@drawable/label_1" style="@style/MMTabButton" />
                </LinearLayout>
                <LinearLayout  android:gravity="top|right|center" android:paddingRight="10.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent">
                    <TextView android:textSize="10.0dip" android:text="1" android:textColor="#ffffff" android:gravity="center" android:id="@+id/main_tab_unread_tv" android:background="@drawable/new_icon_2" android:visibility="invisible" android:layout_width="wrap_content" android:layout_height="wrap_content"  />
                </LinearLayout>
            </FrameLayout>
             <FrameLayout android:background="@null" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0">
                <LinearLayout android:id="@+id/main_layout_myExam" android:gravity="bottom|center" android:layout_width="fill_parent" android:layout_height="fill_parent">
                     <RadioButton android:id="@+id/main_tab_myExam" android:text="我的考试" android:drawableTop="@drawable/label_2" style="@style/MMTabButton" />
                </LinearLayout>
                <LinearLayout android:gravity="top|right|center" android:paddingRight="10.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent">
                    <TextView android:textSize="10.0dip" android:textColor="#ffffff" android:gravity="center" android:id="@+id/main_tab_address" android:background="@drawable/new_icon_2" android:visibility="invisible" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1" />
                </LinearLayout>
            </FrameLayout>
            <FrameLayout android:background="@null" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0">
                <LinearLayout android:id="@+id/main_layout_message" android:gravity="bottom|center" android:layout_width="fill_parent" android:layout_height="fill_parent">
                    <RadioButton android:id="@+id/main_tab_message" android:text="考试资讯" android:drawableTop="@drawable/label_3" style="@style/MMTabButton" />
                </LinearLayout>
                <LinearLayout android:gravity="top|right|center" android:paddingRight="10.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent">
                    <TextView android:textSize="12.0dip" android:textColor="#ffffff" android:gravity="center" android:id="@+id/main_tab_new_tv" android:background="@drawable/new_icon_2" android:visibility="visible" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1" />
                </LinearLayout>
            </FrameLayout>
            <FrameLayout android:background="@null" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0">
                <LinearLayout android:id="@+id/main_layout_settings" android:gravity="bottom|center" android:layout_width="fill_parent" android:layout_height="fill_parent">
                    <RadioButton android:id="@+id/main_tab_settings" android:text="设置" android:drawableTop="@drawable/label4" style="@style/MMTabButton" />
                </LinearLayout>
                <LinearLayout android:gravity="top|right|center" android:paddingRight="10.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent">
                    <TextView android:textSize="10.0dip" android:textColor="#ffffff" android:gravity="center" android:id="@+id/main_tab_setting_new_tv" android:background="@drawable/new_icon_2" android:paddingLeft="6.0dip" android:paddingRight="6.0dip" android:visibility="invisible" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1" />
                </LinearLayout>
            </FrameLayout>
        </LinearLayout>
    </LinearLayout>
</TabHost>

      其实就是用FrameLayout，微信也是这样布局的我反编译过。这样就可以灵活的布局那个红色的图标了。

 

      下面看一下activity切换代码：

 

import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

    }

        main_tab_addExam.setCompoundDrawablesWithIntrinsicBounds(null, getResources().getDrawable(R.drawable.label_one_one), null, null);
        main_layout_addExam.setBackgroundResource(R.drawable.labelbg);

        main_tab_unread_tv=(TextView) findViewById(R.id.main_tab_unread_tv);

                main_tab_message.setBackgroundResource(R.drawable.label_3);*/
                //main_tab_addExam.setCompoundDrawables(null, getResources().getDrawable(R.drawable.label_one_one), null, null);
                main_tab_addExam.setCompoundDrawablesWithIntrinsicBounds(null, getResources().getDrawable(R.drawable.label_one_one), null, null);
                main_tab_myExam.setCompoundDrawablesWithIntrinsicBounds(null, getResources().getDrawable(R.drawable.label_2), null, null);
                main_tab_message.setCompoundDrawablesWithIntrinsicBounds(null, getResources().getDrawable(R.drawable.label_3), null, null);

            }
        });

        main_tab_myExam.setOnClickListener(new OnClickListener() {

                tabHost.setCurrentTabByTag("third");
                /*main_tab_addExam.setBackgroundResource(R.drawable.label_1);
                main_tab_myExam.setBackgroundResource(R.drawable.label_2);

                main_layout_message.setBackgroundResource(R.drawable.labelbg);
                main_layout_settings.setBackgroundResource(R.drawable.mm_trans);
            }
        });

        main_tab_settings.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                tabHost.setCurrentTabByTag("four");
                main_tab_addExam.setCompoundDrawablesWithIntrinsicBounds(null, getResources().getDrawable(R.drawable.label_1), null, null);
                main_tab_myExam.setCompoundDrawablesWithIntrinsicBounds(null, getResources().getDrawable(R.drawable.label_2), null, null);
                main_tab_message.setCompoundDrawablesWithIntrinsicBounds(null, getResources().getDrawable(R.drawable.label_3), null, null);
                main_tab_settings.setCompoundDrawablesWithIntrinsicBounds(null, getResources().getDrawable(R.drawable.label_four_one), null, null);
                main_layout_addExam.setBackgroundResource(R.drawable.mm_trans);
                main_layout_myExam.setBackgroundResource(R.drawable.mm_trans);

    }


    private void initTab(){
        tabHost=getTabHost();
        tabHost.addTab(tabHost.newTabSpec("first").setIndicator("first").setContent(
                new Intent(this, AddExamActivity.class)));

        tabHost.addTab(tabHost.newTabSpec("second").setIndicator("second").setContent(
                new Intent(this, MyExamActivity.class)));

        tabHost.addTab(tabHost.newTabSpec("third").setIndicator("third").setContent(
                new Intent(this, MessageActivity.class)));

        tabHost.addTab(tabHost.newTabSpec("four").setIndicator("four").setContent(
                new Intent(this, SettingActivity.class)));

    }

}

        setCompoundDrawablesWithIntrinsicBounds方法是我用来设置顶部图片的，用来替换android:drawableTop这个属性的背景图，至于为什么那么麻烦每次都要设置背景图片颜色，是因为没用用RadioGroup包含RadioButton，所以RadioButton就不能做到单个切换。
