Android开发案例:SQLite数据库和ListView列表结合

        SQLite是Android系统内置的轻量级的关系型数据库,运行速度非常快;ListView是Android中最常用的的控件之一,几乎所有的应用程序都会用到它。本文通过一个实例介绍如何通过ListView列表展示数据以及实现SQLite数据库的增删改查,并且用到了登录、动画等功能。

首先,新建Android应用程序FileDemo2。代码如下:

        1、src文件夹内,com.demo.adapter包内FileNameAdapter.java文件: 

public class FileNameAdapter extends ArrayAdapter {
	private int resourceId;
	public FileNameAdapter(Context context, int resource, List objects) {
		super(context, resource, objects);
		resourceId=resource;
	}
	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		FileName fileName=getItem(position);
		View view;
		ViewHolder viewHolder;
		if (convertView==null) {
			view=LayoutInflater.from(getContext()).inflate(resourceId, null);
			viewHolder=new ViewHolder();
			viewHolder.fileName=(TextView)view.findViewById(R.id.file_name);
			viewHolder.fileAuthor=(TextView)view.findViewById(R.id.file_author);
			viewHolder.id=0;
			view.setTag(viewHolder);
		} else {
			view=convertView;
			viewHolder=(ViewHolder)view.getTag();
		}
		viewHolder.fileName.setText(fileName.getName());
		viewHolder.fileAuthor.setText(fileName.getAuthor());
		viewHolder.id=fileName.getId();
		return view;
	}
	class ViewHolder{
		TextView fileName;
		TextView fileAuthor;
		int id;
	}
}

        2、src文件夹内,com.demo. beans包内FileName.java文件: 

public class FileName {
	private int id;
	private String name;
	private String author;
	public FileName(int id,String name, String author) {
		this.id=id;
		this.name = name;
		this.author = author;
	}	
	public int getId() {
		return id;
	}
	public String getName() {
		return name;
	}
	public String getAuthor() {
		return author;
	}
	public void setName(String name) {
		this.name = name;
	}
	public void setAuthor(String author) {
		this.author = author;
	}	
}

        3、src文件夹内,com.demo.data包内MyDatabaseHelper.java文件(创建数据库): 

public class MyDatabaseHelper extends SQLiteOpenHelper {	
	public static final String CREATE_MENUNAME="create table MenuName ("
			+"id integer primary key autoincrement, "
			+"menuname text, "
			+"isChosen boolean)";
	public static final String CREATE_FILE="create table FileInfo("
			+"id integer primary key autoincrement, "
			+"title text, "
			+"subtitle text, "
			+"author text, "
			+"partone text, "
			+"parttwo text, "
			+"partthree text, "
			+"partfour text)";	
	private Context mContext;
	public MyDatabaseHelper(Context context, String name,
			CursorFactory factory, int version) {
		super(context, name, factory, version);
		mContext=context;
	}

	@Override
	public void onCreate(SQLiteDatabase db) {
		db.execSQL(CREATE_MENUNAME);
		db.execSQL("insert into MenuName (menuname,isChosen) values (?,?)",new String[]{"标题","1"});
		db.execSQL("insert into MenuName (menuname,isChosen) values (?,?)",new String[]{"副标题","1"});
		db.execSQL("insert into MenuName (menuname,isChosen) values (?,?)",new String[]{"作者","1"});
		db.execSQL("insert into MenuName (menuname,isChosen) values (?,?)",new String[]{"版块一","1"});
		db.execSQL("insert into MenuName (menuname,isChosen) values (?,?)",new String[]{"版块二","1"});
		db.execSQL("insert into MenuName (menuname,isChosen) values (?,?)",new String[]{"版块三","1"});
		db.execSQL("insert into MenuName (menuname,isChosen) values (?,?)",new String[]{"版块四","1"});
		db.execSQL(CREATE_FILE);		
	}

	@Override
	public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
		// TODO Auto-generated method stub		
	}
}

        4、src文件夹内,com.demo.filedemo2包内ActivityCollector.java文件: 

public class ActivityCollector {
	public static List activities = new ArrayList();
	//添加activity
	public static void addActivity(Activity activity){
		activities.add(activity);
	}
	//移除activity
	public static void removeActivity(Activity activity){
		activities.remove(activity);
	}
	//退出
	public static void finishAll(){
		for(Activity activity:activities){
			if (!activity.isFinishing()) {
				activity.finish();
			}
		}
	}
}

        5、src文件夹内,com.demo.filedemo2包内BaseActivity.java文件:

public class BaseActivity extends Activity {
	@Override
	protected void onCreate(Bundle savedInstanceState) {		
		super.onCreate(savedInstanceState);

	}

	protected void onDestroy() {
		super.onDestroy();
		ActivityCollector.removeActivity(this);
	}
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {		
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}
	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		switch (item.getItemId()) {
		case R.id.item_show:
			Intent intent=new Intent(BaseActivity.this, ShowFileNameActivity.class);
			startActivity(intent);
			break;
