答案 0 :(得分：1)
清除第一个Activity onStart（）
上的ArrayList@Override
protected void onStart() {
super.onStart();
lv2.removeAll(lv2);
db=new databaseone(getApplicationContext());
Cursor c=null;
c=db.viewdata(accountId);
while (c.moveToNext()) {
LinkedHashMap<String, String> tran = new LinkedHashMap<String, String>();
String n=c.getString(c.getColumnIndex("id"));
String p=c.getString(c.getColumnIndex("cheqgiven"));
String a=c.getString(c.getColumnIndex("cheqamt"));
tran.put("id", n);
tran.put("cheqgiven", p);
tran.put("cheqamt", a);
lv2.add(tran);
}
c.close();
db.close();
SimpleAdapter adapter = new SimpleAdapter(this, lv2,
R.layout.chequelist, new String[] { "id",
"cheqgiven","cheqamt" }, new int[] { R.id.textAccNo, R.id.textName,R.id.textTransType});
lv.setAdapter(adapter);
} }
第二项活动：
@Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
accountId = this.getIntent().getStringExtra("accountid");
Log.v("one",accountId);
db=new databaseone(getApplicationContext());
Cursor cur=null;
cur=db.viewdata(accountId ); //Change the line
if (cur.moveToFirst()) {
// update view
cheqgiven.setText(cur.getString(cur
.getColumnIndex("cheqgiven")));
cheqamt.setText(cur.getString(cur
.getColumnIndex("cheqamt")));
cheqdate.setText(cur.getString(cur
.getColumnIndex("cheqdate")));
cheqno.setText(cur.getString(cur
.getColumnIndex("cheqno")));
remarks.setText(cur.getString(cur
.getColumnIndex("remarks")));
}
cur.close();
db.close();
}}
然后在数据库中
@Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
db.execSQL("create table if not exists "+TABLE_NAME+" (id integer primary key autoincrement,cheqgiven text,cheqamt text,cheqdate text,cheqno text,remarks text)");
}
@Override
public void onUpgrade(SQLiteDatabase db, int arg1, int arg2) {
// TODO Auto-generated method stub
db.execSQL("drop table if exists "+TABLE_NAME);
onCreate(db);
}
public Cursor viewdata(String acct) {
// TODO Auto-generated method stub
sdb = this.getReadableDatabase();
//Change bellow line to id
String where = (acct == null) ? "" : " where id = " + acct;
Cursor c=sdb.rawQuery("select * from " + TABLE_NAME + where, null);
return c;
