How to add in TextView new data(1 textView = 1 name), from Data Base? in a cycle
I have tableLayout with 3 textView in a TableRow. How to add in TextView new data(1 textView = 1 name), from Data Base? thats doesnt work:
my cursor say: select * from TABLE_NAME
Cursor cursor = database.query(TABLE_NAME,
new String[] {"*"},
null, null,null,null,"_id");
cursor.moveToFirst();
try {
if (!cursor.moveToFirst()) {
return;
}
do {
TextView textView = (TextView)findViewById(R.id.edit);
textView.setText(cursor.getString(0));
} while (cursor.moveToNext());
} finally {
cursor.close();
}
My table:
_id student
1 Said
2 Bill
开发者_运维知识库 3 John
etc
You are overwriting your TextView
identified by edit
each time you call setText(String)
. You may need to create new instances of TextView
programatically.
TableRow row = new TableRow(context);
do {
TextView textView = new TextView(context);
textView.setText(cursor.getString(0));
row.addView(textView); //add each textview to your row
} while (cursor.moveToNext());
myTableLayout.addView(row); //add your row to your table
If you already have a TableLayout
, you can add a TableRow
to it using addView(View v)
. Add new instances of TextView
to your TableRow
and you should get what you want.
