Question

I am having problems getting my TableLayout to display my rows.

I’m propagating the rows programmatically via this method:

private void buildStatesTable() {
    Log.d(SelectStatesPanel.class.getCanonicalName(), "Entering Build States Table");
    ArrayList<String> states = new ArrayList<String>();
    Random rand = new Random();

    for(int i = 0; i < 10; i++){
        if(i < goodStates.length){
            states.add(goodStates[i]);
        }else{
            states.add(badStates[rand.nextInt(badStates.length)]);
        }
    }

    Collections.shuffle(states);

    TableLayout tl = (TableLayout) findViewById(R.id.statesTable);
    final int NUM_PER_ROW = 2;

    for(int i = 0; i < (states.size() / NUM_PER_ROW); i++){
        TableRow tr = new TableRow(getContext());
        tr.setLayoutParams(new LayoutParams(
                LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT));

        for(int j = 0; j < NUM_PER_ROW && (i*NUM_PER_ROW + j) < states.size(); j++){
            TextView lblState = new TextView(getContext());
            lblState.setText(states.get(i*NUM_PER_ROW + j));
            lblState.setTextColor(Color.BLACK);
            lblState.setLayoutParams(new LayoutParams(
                    LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT));
            lblState.setClickable(true);
            lblState.setOnClickListener(this);
            tr.addView(lblState);

            //Log.d(SelectStatesPanel.class.getCanonicalName(), "Adding State: " + states.get(i*NUM_PER_ROW + j));
            Log.d(SelectStatesPanel.class.getCanonicalName(), "\t\t\t (" + i + ", " + j + ")");
        }

        // Add the TableRow to the TableLayout
        tl.addView(tr);
        Log.d(SelectStatesPanel.class.getCanonicalName(), "Adding Row");
    }
}

And this is my XML (table layout is at the bottom):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0"        
        android:layout_margin="5dip"

        android:text="Good choice! There's hope for you yet."
        android:textSize="16dip"
        android:textStyle="bold"
        android:gravity="center"
        />

    <TextView
        android:id="@+id/txtLex"

        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0"        
        android:layout_margin="5dip"

        android:text="Lexington"
        android:textSize="14dip"
        android:gravity="center"
        />
    <TextView
        android:id="@+id/txtTampa"

        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0"        
        android:layout_margin="5dip"

        android:text="Tampa"
        android:textSize="14dip"
        android:gravity="center"
        />
    <TextView
        android:id="@+id/txtSacramento"

        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0"        
        android:layout_margin="5dip"

        android:text="Sacramento"
        android:textSize="14dip"
        android:gravity="center"
        />
    <TextView
        android:id="@+id/txtHiltonhead"

        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0"        
        android:layout_margin="5dip"

        android:text="Hiltonhead"
        android:textSize="14dip"
        android:gravity="center"
        />

    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"        
        android:layout_margin="5dip"

        android:gravity="center"
        android:src="@drawable/usa"
        />
    <TableLayout 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"        
        android:layout_margin="5dip"
        android:id="@+id/statesTable"
        android:stretchColumns="0,1">        
    </TableLayout>


</LinearLayout>

Why isn’t my table layout’s showing content?

Answer 1

I discovered the problem on my own.

The problem was this:

        lblState.setLayoutParams(new LayoutParams(
                LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT));

Specifying TableRow.LayoutParams fixed the problem.
