1、在ListView里显示数据
private void show1() { Cursor cursor=service.getCursorScrollData(0, 20);//需要绑定的数据，getCursorScrollData（）代码在下方 SimpleCursorAdapter adapter=new SimpleCursorAdapter(this,R.layout.item, cursor, new String[]{"name","phone","amount"}, new int[]{R.id.name,R.id.phone,R.id.amount}); listView.setAdapter(adapter); }2、getCursorScrollData（）代码
public Cursor getCursorScrollData(int offset,int maxResult){//使用SimpleCursorAdapter注意要包含_id字段 SQLiteDatabase db=dbOpenHelper.getReadableDatabase(); Cursor cursor=db.rawQuery("select personid as _id,name,phone,amount from person order by personid asc limit?,?", new String[]{String.valueOf(offset),String.valueOf(maxResult)}); return cursor; }3、一条数据单击事件
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); service=new PersonService(this); listView=(ListView)this.findViewById(R.id.listview); show(); listView.setOnItemClickListener(new ItemClickListener()); } private final class ItemClickListener implements OnItemClickListener{ @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { ListView listView=(ListView)arg0; //SimpleCursorAdapter适配器 Cursor cursor=(Cursor)listView.getItemAtPosition(arg2); String name=cursor.getString(cursor.getColumnIndex("name")); Toast.makeText(getApplicationContext(), name, 2).show(); } }
