我的应用程序中有一个数据库，我使用一个表单使用edittext输入数据，完成后，用户将单击提交。我点击之前输入的列表数据之一到另一个活动，以显示之前输入的数据，它会强制关闭。我不知道我的错在哪里 这是我的数据库：
class DBSpaj extends SQLiteOpenHelper {
private static final String DATABASE_NAME="dbspaj.db";
private static final int SCHEMA_VERSION=1;
public DBSpaj(Context context) {
super(context, DATABASE_NAME, null, SCHEMA_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("DROP TABLE IF EXISTS table_spaj");
db.execSQL("CREATE TABLE if not exists table_spaj (_id INTEGER PRIMARY KEY AUTOINCREMENT," +
" agama TEXT,"+
" agamatt TEXT,"+
" alamat TEXT,"+
" alamat_tt TEXT,"+
" alamat_tagihan TEXT,"+
" alamat_tagihan_tt TEXT,"+
" alamatkantor TEXT,"+
" curenttime TEXT," +
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// no-op, since will not be called until 2nd schema
// version exists
}
public Cursor getAll() {
return(getReadableDatabase()
.rawQuery("SELECT _id, agama,agamatt,alamat,alamat_tt,alamat_tagihan,alamat_tagihan_tt,alamatkantor,curenttime FROM table_spaj ORDER BY edit_nama_pp", null));
}

getWritableDatabase().insert("table_spaj", "name", cv);

我不知道为什么我不能显示我之前输入的数据，我希望有人可以帮我解决我的问题，谢谢。
答案 0 :(得分：5)
当您的查询返回一个新游标时，它最初指向结果索引-1，这意味着“在第一行之前”。您必须先在光标上调用其中一个移动方法，例如moveToFirst()，然后将其移动到有效的结果行。 （检查移动的结果以确保它指向有效行。）
在您的堆栈跟踪中，您可以看到getagama()中的光标行访问权限为SPajView.onCreate()。因此，要修复此特定崩溃，请在moveToFirst()中添加以下SPajView.onCreate()：
if (model.moveToFirst()) {
agama.setText(helper.getagama(model));
//...
}
答案 1 :(得分：0)
你不要使用它：
agama.setText(helper.getagama(model));
agamatt.setText(helper.getagamatt(model));
alamat.setText(helper.getalamat(model));
alamat_tt.setText(helper.getalamat_tt(model));
alamat_tagihan.setText(helper.getalamat_tagihan(model));
alamat_tagihan_tt.setText(helper.getalamat_tagihan_tt(model));
alamatkantor.setText(helper.getalamatkantor(model));
getcurenttime.setText(helper.getcurenttime(model));
因为model返回了Cursor。另外，您可以使用SimpleCursorAdapter
