我有ListView它有三个TextViews和一个Button。我必须从一个表中获取数据以填充TextViews，并且Button由其他表中的数据填充。我使用TextViews填充了第一个表格中的CursorAdapter。现在我不知道如何在第二个数据库表的同一Button项中填充不可点击的ListView。有没有办法从两个单独的表中填充自定义ListView项？
我的DBHelper是
public class DatabaseHelper extends SQLiteOpenHelper {
public static final String db_name="unitdb";
public static final int version=1;
Context context;
public DatabaseHelper(Context context){
super(context, db_name, null, version);
this.context=context;
}
@Override
public void onCreate(SQLiteDatabase db){
db.execSQL("CREATE TABLE bikeTable( _id INTEGER PRIMARY KEY AUTOINCREMENT, userName TEXT, mobileNo INTEGER, address TEXT, uSerialNo INTEGER UNIQUE, uImeiNo integer, uCimiNo INTEGER, uContactNo INTEGER, dealerCode INTEGER, dealerContactNo INTEGER, vehicleType TEXT)");
Toast.makeText(context,"Database Created",Toast.LENGTH_SHORT).show();
Log.i("dbcreate", "Database Created");
Log.i("Table Created", "Bike Tracker Table Created");
db.execSQL("CREATE TABLE dealerTable(_id INTEGER PRIMARY KEY AUTOINCREMENT, dealerName TEXT, mobileNo INTEGER, dealerCode INTEGER UNIQUE, address TEXT)");
Log.i("Table Created", "Dealer Details Table Created");
db.execSQL("CREATE TABLE statusTable(_id INTEGER PRIMARY KEY AUTOINCREMENT, userName TEXT, mobileNo INTEGER, serialNo INTEGER, deviceContact INTEGER, sentTime TEXT, sent TEXT, delivered TEXT, reply TEXT )");
Log.i("Table Status Created","Status Table Created");
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
if (oldVersion>=newVersion)
return;
if (oldVersion==1){
Log.d("New Version","Data's can be Upgraded");
}
Log.d("Sample Data", "onUpgrade:" + newVersion);
}
public Cursor getAllDataBike(){
String query= "select rowid _id,* from bikeTable where vehicleType='Two Wheeler'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getAllDataCar(){
String query= "select rowid _id,* from bikeTable where vehicleType='Car'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getAllDataCv(){
String query= "select rowid _id,* from bikeTable where vehicleType='Commercial Vehicle'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getDealers(){
String query="select rowid _id,* from dealerTable";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor searchCustomerBike(String strFilter){
String query;
query="Select rowid _id,* from bikeTable where uSerialNo='"+strFilter+"' AND vehicleType='Two Wheeler'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor searchCustomerCar(String strFilter){
String query;
query="Select rowid _id,* from bikeTable where uSerialNo='"+strFilter+"' AND vehicleType='Car'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor searchCustomerCv(String strFilter){
String query;
query="Select rowid _id,* from bikeTable where uSerialNo='"+strFilter+"' AND vehicleType='Commercial Vehicle'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getActivated(){
String query="Select rowid _id,* from bikeTable where userName IS NOT NULL AND vehicleType='Two Wheeler'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getNotActivated(){
String query="Select rowid _id,* from bikeTable where userName IS NULL AND vehicleType='Two Wheeler'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getActivatedCar(){
String query="Select rowid _id,* from bikeTable where userName IS NOT NULL AND vehicleType='Car'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getNotActivatedCar(){
String query="Select rowid _id,* from bikeTable where userName IS NULL AND vehicleType='Car'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getActivatedCv(){
String query="Select rowid _id,* from bikeTable where userName IS NOT NULL AND vehicleType='Commercial Vehicle'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getNotActivatedCv(){
String query="Select rowid _id,* from bikeTable where userName IS NULL AND vehicleType='Commercial Vehicle'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
public Cursor getStatus(String srNo){
String query="select rowid _id,* from statusTable where serialNo='"+srNo+"'";
SQLiteDatabase db=this.getReadableDatabase();
return db.rawQuery(query,null);
}
}
我的CursorAdapter是
public class DisplayAdapter extends CursorAdapter{
DatabaseHelper databaseHelper;
SQLiteDatabase db;
@SuppressWarnings("deprecation")
public DisplayAdapter(Context context,Cursor c){
super(context,c);
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View retView = inflater.inflate(R.layout.card_items, parent, false);
return retView;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
TextView tvUserName=(TextView)view.findViewById(R.id.textView27);
tvUserName.setText(cursor.getString(2));
TextView tvMobile=(TextView)view.findViewById(R.id.textView28);
tvMobile.setText(cursor.getString(3));
TextView tvSerail=(TextView)view.findViewById(R.id.textView29);
tvSerail.setText(cursor.getString(5));
}
}
