Android学习12——Tab组件和ListView组件结合

Tab组件和ListView组件结合的关键代码，用一个Activity调用另一个Activity,使另一个Activity开始执行：

Intent intent = new Intent();
intent.setClass(this, Tab01Activity.class);
TabHost.TabSpec tab01 = tabHost.newTabSpec("tab01")
.setIndicator("选项1", resources.getDrawable(R.drawable.p1))
.setContent(intent);

页面布局：

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent" >

    <!-- <ImageView

        android:id="@+id/a"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:src="@drawable/a" /> -->

    <ImageView

        android:id="@+id/b"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:src="@drawable/b" />

    <ImageView

        android:id="@+id/c"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:src="@drawable/c" />

</RelativeLayout>

mian.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent" >

    <ListView

        android:id="@+id/listview"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent" />

</RelativeLayout>

list_item.xml:

<?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="horizontal" >

    <!-- 左边是图片 -->

    <ImageView

        android:id="@+id/photo"

        android:layout_width="48dp"

        android:layout_height="48dp" />

    <!-- 右边是个布局 -->

    <LinearLayout

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:orientation="vertical" >

        <!-- 上面是个布局 -->

        <LinearLayout

            android:layout_width="fill_parent"

            android:layout_height="wrap_content"

            android:orientation="horizontal" >

            <TextView

                android:id="@+id/name"

                android:layout_width="wrap_content"

                android:layout_height="wrap_content" />

            <TextView

                android:textSize="10dp"

                android:id="@+id/publish"

                android:layout_width="fill_parent"

                android:layout_height="wrap_content"

                android:gravity="right" />

        </LinearLayout>

        <!-- 发布内容 -->

        <TextView

            android:textSize="10dp"

            android:id="@+id/content"

            android:layout_width="fill_parent"

            android:layout_height="wrap_content" />

    </LinearLayout>

</LinearLayout>

主要代码 ：MainActivity.java:

package com.zzw.tabandlistview;

import android.os.Bundle;

import android.app.Activity;

import android.app.TabActivity;

import android.content.Intent;

import android.content.res.Resources;

import android.view.LayoutInflater;

import android.view.Menu;

import android.view.MenuItem;

import android.widget.TabHost;

import android.support.v4.app.NavUtils;

public class MainActivity extends TabActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TabHost tabHost = getTabHost();
LayoutInflater inflater = LayoutInflater.from(this);
inflater.inflate(R.layout.activity_main, tabHost.getTabContentView());
Resources resources = getResources();

Intent intent = new Intent();
intent.setClass(this, Tab01Activity.class);
TabHost.TabSpec tab01 = tabHost.newTabSpec("tab01")
.setIndicator("选项1", resources.getDrawable(R.drawable.p1))
.setContent(intent);

/*
* TabHost.TabSpec tab01 = tabHost.newTabSpec("tab01")
* .setIndicator("选项1", resources.getDrawable(R.drawable.p1))

*/
TabHost.TabSpec tab02 = tabHost.newTabSpec("tab02")
.setIndicator("选项2", resources.getDrawable(R.drawable.p2))
.setContent(R.id.b);
TabHost.TabSpec tab03 = tabHost.newTabSpec("tab03")
.setIndicator("选项3", resources.getDrawable(R.drawable.p3))
.setContent(R.id.c);
tabHost.addTab(tab01); 
tabHost.addTab(tab02);
tabHost.addTab(tab03);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}

}

Tab01Activity.java:

package com.zzw.tabandlistview;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import android.os.Bundle;

import android.provider.ContactsContract.Data;

import android.app.Activity;

import android.view.Menu;

import android.view.MenuItem;

import android.view.View;

import android.widget.AdapterView;

import android.widget.AdapterView.OnItemClickListener;

import android.widget.ListView;

import android.widget.SimpleAdapter;

import android.widget.Toast;

import android.support.v4.app.NavUtils;

public class Tab01Activity extends Activity {
private ListView listView;
private List<Map<String, ?>> data;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
listView = (ListView) this.findViewById(R.id.listview);
data = getData();
SimpleAdapter adapter = new SimpleAdapter(this, data,
R.layout.list_item, new String[] { "photo", "name", "publish",
"content" }, new int[] { R.id.photo, R.id.name,
R.id.publish, R.id.content });
listView.setAdapter(adapter);
listView.setOnItemClickListener(new ListViewHandler());
}
private class ListViewHandler implements OnItemClickListener{

@Override
public void onItemClick(AdapterView<?> listview, View view, int postion,long id){
Map<String,?> item=data.get(postion);
Toast.makeText(getApplicationContext(), item.get("name").toString(), Toast.LENGTH_LONG).show();

}
}
private List<Map<String, ?>> getData() {
List<Map<String, ?>> data = new ArrayList<Map<String, ?>>();
Map<String, Object> item = new HashMap<String, Object>();
item.put("photo", R.drawable.p1);
item.put("name", "嘿嘿");
item.put("publish", "一分钟前");
item.put("content", "好好学习Android");
data.add(item);
item = new HashMap<String, Object>();
item.put("photo", R.drawable.p2);
item.put("name", "嘻嘻");
item.put("publish", "三分钟前");
item.put("content", "好好学习");
data.add(item);
return data;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}

}

运行程序效果如下：
