Question

I am doing lazyloading to display images and text. I have got everything up and now, trying to add a textview in the view. However, my adapter is overlapping my view. Simpler terms is that, the listview is overlapping the textview. I’m not sure where I’m doing it wrong because the original example is able to display a button just below the listview but I’m not. I’m not getting any errors. My listview just covers the whole screen. Any idea what might be the problem?

main.java

public class main extends Activity {

private static final String targetURL ="http://www.google.com/images";
ListView list;

ProgressDialog dialog;
private String[] mStrings = {};
private String[] dStrings = {};
//TextView tv;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);         
    new TheTask().execute();
    list=(ListView)findViewById(R.id.list);
    TextView tv = (TextView)findViewById(R.id.tv);

    //tv.setText("Text View is displayed");
}   


protected class TheTask extends AsyncTask<Void, Void, MyResultClass >{

    protected void onPreExecute() {
        dialog = ProgressDialog.show(Cats.this, "Retrieving Information", "Please wait for few seconds...", true, false);
        dialog.setCancelable(true);
    }

    protected MyResultClass doInBackground(Void... params) {
        searchContent();
        MyResultClass result = new MyResultClass();
        result.mStrings = mStrings;
        result.dStrings = dStrings;
        return result;
    }   

    protected void onPostExecute(MyResultClass result) {            
        dStrings = result.dStrings;
        mStrings = result.mStrings;         
        LazyAdapter adapter = new LazyAdapter(Cats.this, mStrings, dStrings);
        list.setAdapter(adapter);
        dialog.dismiss();
    }       
}

    class MyResultClass

                int endIndex = line.indexOf(">", startIndex + 1);
                String abc = "http://www.google.com/";
                String imageSrc = line.substring(startIndex,endIndex);
                //complete full url

Answer 1

Just remove the + symbol from this line

android:layout_below="@+id/linear1"

in second linear layout stanza.
