Two Checkboxes in a single TableRow?

Question

I am trying to fit two CheckBoxes into a single TableRow, so that they sit side by side. My program crashes at run time as soon as I try to load the view.

I previously had them each in their own row, but want to change them to fitting in the same row. I have messed with the android:layout_width feature but to no avail. This is the code I have for the TableRow.

         <TableRow>
            <CheckBox 
                android:id="@+id/circleCloseCheck"
                android:text="@string/parameters_circle_close"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" />

            <CheckBox
                android:id="@+id/nwpCheck"
                android:text="@string/parameters_nwp_check"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" />
        </TableRow>

This is my LogCat...

EDIT :

Here is the information for line 534 in my Parameters.java file. Line 534 is wattVarCurrentSpinner = (Spinner) findViewById( R.id.wattVarCurrentSpinner.

    wattVarCurrentRelayList = new ArrayList<String>();
    wattVarCurrentRelayList.add( "N/A" );
    for( int i = 1; i <= 100; i++ ) {
        double temp = (i/10.0);
        wattVarCurrentRelayList.add( String.valueOf( temp ) );
    }
    wattVarCurrentSpinner = (Spinner) findViewById( R.id.wattVarCurrentSpinner );
    if( RelayAPIModel.AppPrefsType.displayUnits.equals( "Relay" ) ) {
        wattVarCurrentAdapter = new ArrayAdapter<String>( this, android.R.layout.simple_spinner_item, wattVarCurrentRelayList );
    } else if( RelayAPIModel.AppPrefsType.displayUnits.equals( "Protector" ) ) {
        wattVarCurrentAdapter = new ArrayAdapter<String>( this, android.R.layout.simple_spinner_item, wattVarCurrentProtectorList );
    } else if( RelayAPIModel.AppPrefsType.displayUnits.equals( "Percent" ) ) {
        wattVarCurrentAdapter = new ArrayAdapter<String>( this, android.R.layout.simple_spinner_item, wattVarCurrentPercentList );      
    } else {
        RelayAPIModel.AppPrefsType.displayUnits = "Relay";
        wattVarCurrentAdapter = new ArrayAdapter<String>( this, android.R.layout.simple_spinner_item, wattVarCurrentRelayList );
    }
    wattVarCurrentAdapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );
    wattVarCurrentSpinner.setAdapter( wattVarCurrentAdapter );

There's a ClassCastException thrown in file Parameters.java at line 534. — rocky3000, Aug 23 '12 at 13:08
Um, nothing that pertains to the check boxes, but I will edit my post now and add it. Sorry, I had only changed the checkboxes in my XML file and saw it say something about a checkbox so I assumed it was an XML problem. — JuiCe, Aug 23 '12 at 13:15

should be android:layout_width="wrap_content" in each checkbox; you should also add android:layout_weight="1.0" to every checkbox

perfect example is here:SO answer

I think you forgot to add layout_width and layout_height for TableRow Also need to change the check box layout_width to "wrap_content"

    <TableRow
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

    <CheckBox
        android:id="@+id/circleCloseCheck"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/parameters_circle_close" />

    <CheckBox
        android:id="@+id/nwpCheck"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/parameters_nwp_check" />
</TableRow>

Not sure if this was the answer, but I did this then cleaned my project and it worked. Thanks. — JuiCe, Aug 23 '12 at 13:19
