[android-beginners] Problems with combined scrollview and tablelayout

[robbidog]

Hi,
  I'm trying out the SDK and am attempting to combine a ScrollView
with  table layout and GridView.  For each row of the table I want a
list of TextView's stored in GridView. With my current layout, all of
the text views in the grid end up overlaying each other.  Can anyone
tell me how to give each TextView in the grid a set width so that I
can see each text value?  I've tried both the ScrollView and
HorizontalScrollView widgets and both produce the same results.

I've developed a basic Adapter for the GridView which may be the
problem.  I can't find any good examples or other doc's that explan
the us of the Adater class for gridview any better.
I'm using the following layout:
<?xml version="1.0" encoding="utf-8"?>

<HorizontalScrollView
android:id="@+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android";>
        <TableLayout
        android:id="@+id/TableLayout01"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent">
                <TableRow
                android:id="@+id/TableRow01"
                android:layout_height="wrap_content"
                android:layout_width="fill_parent">
                        <TextView
                        android:id="@+id/TextView01"
                        android:layout_height="wrap_content"
                        android:layout_width="fill_parent"
                        android:text="Inning">
                        </TextView>
                        <GridView
                        android:id="@+id/GridView01"
                        android:layout_height="wrap_content"
                        android:layout_width="fill_parent"
                        android:numColumns="10"
                        android:minWidth="25px">
                        </GridView>
                </TableRow>
        </TableLayout>
</HorizntalScrollView>




I've set up a very basic grid adapter here's the code:

package com.example.hsview;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.TextView;

public class GridAdapter extends BaseAdapter {

        private Context context;
        private String[] texts = {"1", "2", "3", "4", "5", "6", "7", "8",
"9", "Out"};

        public GridAdapter(Context context) {
            this.context = context;
        }

        public int getCount() {
                return texts.length;
        }
        public Object getItem(int position) {
                        return texts[position];
        }

        public long getItemId(int position) {
            return position;
        }
        public View getView(int position, View convertView, ViewGroup parent)
{
            TextView tv;
            if (convertView == null)
            {
                        tv = new TextView(context);
                        tv.setLayoutParams(new GridView.LayoutParams(30, 30));
            }
            else
            {
                tv = (TextView) convertView;
            }

        tv.setText(texts[position]);
        tv.setWidth(30);
            return tv;
        }
}

And finally, here's the app startup code:
package com.example.hsview;

import android.app.Activity;
import android.os.Bundle;
import android.widget.GridView;

public class ExampleHSView extends Activity {
        GridView inningView, homescoreView;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        inningView = (GridView)this.findViewById(R.id.GridView01);
        inningView.setAdapter(new GridAdapter(this));
    }
}
