Passing database data to another activity - eclipse

Question

how can I pass an array of strings and integers which contains the database data into another activity...I don't know how to put the database data on the string array

Answer 1

You can use this method to retrieve data from the table
public List<String[]> getData(String query) throws SQLException{
Cursor c = mdb.rawQuery(query, null);
c.moveToFirst();
List<String[]> data = new ArrayList<String[]>();
if (c != null) {
for (int i = 0; i < c.getCount(); i++) { // iterate rows
String[] row = new String[c.getColumnCount()];
for(int j = 0; j < c.getColumnCount(); j++){//iterate columns
row[j] = c.getString(j);
}
data.add(row);
c.moveToNext();
}
}
c.close();
Log.i("getData", data.size() + " rows returned");
return data;
}
Each row of the result will be contained in each String[] of the list.
Say, intentData is a String[] and you want to pass the data to the next activity.For this, you have to add the data to the Intent like this
Intent intent = new Intent(CurrentAct.this, NextAct.class);
intent.putExtra("dbData", intentData);
startActivity(intent);
You can retrieve the data from NextAct's onCreate() method like this :
String[] passedData = getIntent().getExtras().getStringArray("dbData");
