may help you . Take a look at the "Notes" sample that comes with the toolkit. They fill ListViews from databases here. This gives you a first idea. Ask more specific questions then.

it should still fix some issue All 3 lines get executed, but you're always overriding the text color with the next line. Use a condition instead:
code :
if (priority.equals("Low")) {
   holder.viewName.setTextColor(Color.BLUE);
} else if (priority.equals("Medium")) {
   holder.vieName.setTextColor(Color.GREEN);
} else if (priority.equals("High")) {
   holder.viewName.setTextCOlor(Color.RED);
} else {
   holder.viewName.setTextColor(Color.GRAY);
}

hope this fix your issue from your 2nd activity, when your data set is changed, send a broadcast notification.
In your primary activity, register a broadcast receiver to listen for these changes, and call mListViewAdapter.notifyDataSetChanged() to reload the list view.

I think the issue was by ths following , first i do not think your program has any problem and i think this happens because the image has not completely downloaded from internet.In order to confirm this you can scroll the list and stop it suddenly to see if wrong images replace by correct one or not!! you can solve this problem by using placeholder image and error image in your request like this:
code :
imageLoader.get(URL_IMAGE, ImageLoader.getImageListener(
                imageView, R.drawable.ico_loading, R.drawable.ico_error));

it should still fix some issue I found the problem in the WebView coming from the advertiser. The problem seems to be setting the LayerType to HARDWARE. That caused the Problem. Setting the the LayerType to NONE or SOFTWARE the problem went away. Now I just wonder WHY that caused the problem.
A normal WebView uses LAYER_TYPE_NONE by default.
code :
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
There are two errors, I can not solve it(ListView)

hope this fix your issue Move your adapter initialization inside onCreate. You need to set the adapter to the ListView using setAdapter. Call noftifyDataSetChanged after populating the dataset arr.
Try this code,
code :
private MyAdapter ma;

onCreate(){
    ...
    setContentView(R.layout.activty_main2);
    lv = (ListView) findViewById(R.id.lv_1);
    ma = new MyAdapter(this, arr);
    lv.setAdapter(ma);
    initData();
}

initData(){
    for(;;){
        ...
        arr.add(n);     
    }
    ma.noftifyDataSetChanged();
}
