I am wanting to do 4 columns with dynamically changing rows of data. I would do this with LinearLayout, but I cannot find a good way to get a 4x10 set of textviews. This .java is trowing a fatal error which is listed at the bottom:
public class DebtList extends Activity {
Integer trigger = 5;
Double totalDebt = 0.00;
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.debtlist);
//Bundle extras = getIntent().getExtras();
String[] debtNames = new String[10];
Double[] debtAmount = new Double[10];
Double[] debtRate = new Double[10];
Double[] debtTerm = new Double[10];
Integer stopper = trigger+1;
TableLayout tl=(TableLayout)findViewById(R.id.debtlist);
TableRow tr1 = new TableRow(this);
TextView textview = new TextView(this);
for(int i=0; i<stopper; i++)
{
tr1.setLayoutParams(new LayoutParams( LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
tr1.setId(i);
textview.setText("" + i);
tr1.addView(textview);
tl.addView(tr1, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
tr1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT));
tr1.setId(i);
}
trigger++;
}
}
I have a (basically) blank .XML to work with:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/debtlist"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</TableLayout>

If anyone has any more efficient ways to get a 4X1-10 set of TextViews to be displayed based on the amount of data input by the user, please let me know.
Also I'm using API level 12
as in log :
ClassCastException: android.app.ActionBar$LayoutParams cannot be cast to android.widget.LinearLayout$LayoutParams
means you are importing ActionBar.LayoutParams
for setting LayoutParams to TableLayout and Buttons so use LinearLayout.LayoutParams as:
for(int i=0; i<stopper; i++)
{
tr1.setLayoutParams(new LinearLayout.LayoutParams( LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
//.....
tr1.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT)));
tr1.setId(i);
}
You are getting class cast exception because you are using Table Layout and inflating context of ActionBar Linear Layout.
java.lang.ClassCastException: android.app.ActionBar$LayoutParams cannot be cast to android.widget.LinearLayout$LayoutParams
is there a way 4 columns per row for x number of rows ?
Use a custom layout for this and use it .
for(int i=0; i<stopper; i++)
{
// Inflate your row "template" and fill out the fields.
TableRow row = (TableRow)LayoutInflater.from(context).inflate(R.layout.attrib_row, null);
((TextView)row.findViewById(R.id.attrib_name)).setText(b.NAME);
((TextView)row.findViewById(R.id.attrib_value)).setText(b.VALUE);
table.addView(row);
}
