    <p>I started a test project just to get this down. No changes to main.xml. I want to create a widget-sized ImageView (80x100) that contains a Bitmap converted from a TextView. Yes, that sounds very roundabout but this is just for testing; in the end I want the ImageView to have a background image and multiple TextViews. I'm not sure exactly what I'm doing wrong, but nothing is being pushed to the screen.</p> <p>Is it a problem with declaring the TextView/ImageView and passing it "this" in the constructor? Is it a problem with my layoutParams? Here is the code:</p> <pre><code>package com.doaf.testproject; import android.app.Activity; import android.graphics.Bitmap; import android.graphics.Canvas; import android.os.Bundle; import android.view.View; import android.widget.ImageView; import android.widget.LinearLayout; import android.widget.TextView; public class TestProject extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(80, 100); tv.setLayoutParams(layoutParams); tv.setText("testing 1 2 3"); tv.setTextColor(0xFFFFFF); tv.setBackgroundColor(0x555555); Bitmap testB; testB = loadBitmapFromView(tv); ImageView iv = new ImageView(this); iv.setLayoutParams(layoutParams); iv.setBackgroundColor(0x555555); iv.setImageBitmap(testB); setContentView(iv); } public static Bitmap loadBitmapFromView(View v) { Bitmap b = Bitmap.createBitmap(80, 100, Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); v.layout(0, 0, 80, 100); v.draw(c); return b; } } </code></pre> <p>Thanks for any help you can provide. I'm relatively new to Android, and pretty lost with this one.</p>

    3. CO@Tilsan The Fighter: I plan on using a custom layout. The end intent is to generate a LinearLayout made up of an optional background image and a few TextViews, then export that LinearLayout to a Bitmap and then to the background of a widget (ImageView?).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
