Android开发学习之LauncherActivity开发启动的列表

创建项目：OtherActivity

项目运行结果：

建立主Activity:OtherActivity.java

[java]
package wwj.otherActivity;

import android.os.Bundle;
import android.app.Activity;
import android.app.LauncherActivity;
import android.content.Intent;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;
import android.support.v4.app.NavUtils;

public class OtherActivity extends LauncherActivity {

    //定义两个Activity的名称
    String[] names = {"设置程序参数", "查看星际兵种"};
    //定义两个Activity对应的实现类
    Class<?>[] clazzs = {PreferenceActivityTest.class,
            ExpandableListActivityTest.class};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.易做图_list_item_1
                , names);
        // 设置该窗口显示的列表所需的Adapter
        setListAdapter(adapter);
    }
    //根据列表项返回指定Activity对应的Intent
    @Override
    protected Intent intentForPosition(int position) {
        // TODO Auto-generated method stub
        return new Intent(OtherActivity.this, clazzs[position]);
    }
}

package wwj.otherActivity;

import android.os.Bundle;
import android.app.Activity;
import android.app.LauncherActivity;
import android.content.Intent;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;
import android.support.v4.app.NavUtils;

public class OtherActivity extends LauncherActivity {

//定义两个Activity的名称
String[] names = {"设置程序参数", "查看星际兵种"};
//定义两个Activity对应的实现类
Class<?>[] clazzs = {PreferenceActivityTest.class,
   ExpandableListActivityTest.class};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.易做图_list_item_1
          , names);
        // 设置该窗口显示的列表所需的Adapter
        setListAdapter(adapter);
    }
    //根据列表项返回指定Activity对应的Intent
    @Override
    protected Intent intentForPosition(int position) {
    // TODO Auto-generated method stub
    return new Intent(OtherActivity.this, clazzs[position]);
    }
}
建立第一个列表项的Activity:PreferenceActivityTest.java

[java]
package wwj.otherActivity;

import android.os.Bundle;

public class PreferenceActivityTest extends android.preference.PreferenceActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        //设置显示参数设置布局
        addPreferencesFromResource(R.xml.preferences);
    }
}

package wwj.otherActivity;

import android.os.Bundle;

public class PreferenceActivityTest extends android.preference.PreferenceActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  //设置显示参数设置布局
  addPreferencesFromResource(R.xml.preferences);
}
}

PreferenceActivity使用的界面布局文件

[html]
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
    
    <RingtonePreference
        android:ringtoneType="all"
        android:title="设置铃声"
        android:summary="选择铃声"
        android:showDefault="true"
        android:key="ring_key"
        android:showSilent="true">
    </RingtonePreference>
    <PreferenceCategory
        android:title="个人信息设置组">
        
        <EditTextPreference
            android:key="name"
            android:title="用户名"
            android:summary="填写你的用户名"
            android:dialogTitle="您所使用的用户名为: "
            />
        
        <ListPreference
            android:key="gender"
            android:title="性别"
            android:summary="选择您的性别"
   &nbs
