【原创】android——Tabhost 自定义tab+底部实现+intent切换内容

1，实现tabhost自定义格式，再此仅仅显示背景和文字，效果图预览：（底边栏所示）

（图片变形）

2，xml配置

 1 <TabHost xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:id="@+id/tabhost"
 4     android:layout_width="match_parent"
 5     android:layout_height="match_parent"
 6     android:layout_alignParentBottom="true"
 7     tools:context="${relativePackage}.${activityClass}" >
 8
 9     <LinearLayout
10         android:id="@+id/linearLayout1"
11         android:layout_width="fill_parent"
12         android:layout_height="fill_parent"
13         android:orientation="vertical"
14         >
15           <TextView
16             android:id="@+id/user_welcome"
17             android:layout_width="match_parent"
18             android:layout_height="15dp"
19             android:background="#56a692"
20             android:textColor="#fff"
21             android:gravity="bottom"
22             android:textSize="12sp"/>
23
24         <FrameLayout
25             android:id="@android:id/tabcontent"
26             android:layout_width="fill_parent"
27             android:layout_height="0dp"
28             android:layout_weight="4.25" >
29              <!-- 摆设 -->
30         </FrameLayout>
31
32         <TabWidget
33             android:id="@android:id/tabs"
34             android:layout_width="match_parent"
35             android:layout_height="50dp"
36             android:background="#EECFA1" >
37         </TabWidget>
38
39     </LinearLayout>
40
41 </TabHost>

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     android:layout_width="80dp"
 4     android:layout_height="80dp"
 5     android:orientation="vertical">
 6         <TextView android:id="@+id/tab_label2"
 7         android:layout_width="fill_parent"
 8         android:layout_height="wrap_content"
 9         android:gravity="center"
10         android:textColor="#FFF"
11         android:textStyle="bold"
12         android:background="@drawable/tablost"/>
13
14 </LinearLayout>

2，主界面的实现

 1 package com.example.dbtest;
 2
 3 import android.annotation.SuppressLint;
 4 import android.app.Activity;
 5 import android.app.LocalActivityManager;
 6 import android.content.Intent;
 7 import android.os.Bundle;
 8 import android.view.LayoutInflater;
 9 import android.view.View;
10 import android.widget.TabHost;
11 import android.widget.TextView;
12
13
14 @SuppressWarnings("deprecation")
15 @SuppressLint("InflateParams")
16 public class User extends Activity {
17
18     private TextView tv_welcome;
19     private TabHost tab;
20
21     @SuppressLint("InflateParams")
22     @Override
23     protected void onCreate(Bundle savedInstanceState) {
24         super.onCreate(savedInstanceState);
25         setContentView(R.layout.activity_user);
26         tv_welcome=(TextView)findViewById(R.id.user_welcome);
27         //设置title
28         Bundle bundle=this.getIntent().getExtras();
29         String username=bundle.getString("name");
30         tv_welcome.setText("欢迎您！"+username);
31         //添加groupActivity 是实现intent的必要
32         LocalActivityManager groupActivity =new LocalActivityManager(this,false);
33         groupActivity.dispatchCreate(savedInstanceState);
34
35
36
37 View mesTab = (View) LayoutInflater.from(this).inflate(R.layout.lost,null);
38  TextView mes = (TextView) mesTab.findViewById(R.id.tab_label2);
39  mes.setText("发布");
40
41 View lostTab = (View) LayoutInflater.from(this).inflate(R.layout.lost, null);
42 TextView lost = (TextView) lostTab.findViewById(R.id.tab_label2);
43 lost.setText("失物");
44
45 View foundTab = (View) LayoutInflater.from(this).inflate(R.layout.lost, null);
46 TextView found = (TextView) foundTab.findViewById(R.id.tab_label2);
47  found.setText("招领");
48
49 View toolTab = (View) LayoutInflater.from(this).inflate(R.layout.lost, null);
50  TextView tool = (TextView) toolTab.findViewById(R.id.tab_label2);
51 tool.setText("搜索");
52
53  tab=(TabHost)findViewById(R.id.tabhost);
54 //这里引用groupactivity
55 tab.setup(groupActivity);
56
57
58 //下面分别是跳转到不同的activity
59 Intent intent=new Intent(User.this,User_center.class);
60 tab.addTab(tab.newTabSpec("mes").setIndicator(mesTab).setContent(intent));
61
62 Intent intent1=new Intent(User.this,User_lost.class);
63 tab.addTab(tab.newTabSpec("lost").setIndicator(lostTab).setContent(intent1));
64
65  Intent intent2=new Intent(User.this,User_found.class);
66 tab.addTab(tab.newTabSpec("found").setIndicator (foundTab).setContent(intent2));
67
68  Intent intent3=new Intent(User.this,User_tool.class);
69 tab.addTab(tab.newTabSpec("tool").setIndicator(toolTab).setContent(intent3));
70
71
72     }
73
74
75 }
