Question

I need some help creating a listview inside a layout i have. im having torubles creating it properly.

Here is what i got so far.

item.xml

   <?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" >

<LinearLayout
    android:id="@+id/listview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/list_selector" >


    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/gradient_bg"
        android:src="@drawable/gs3ultimate" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/label"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/thelistarray"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="#555555" />

        <TextView
            android:id="@+id/summary"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/thelistarry_details"
            android:textColor="#555555"
            android:textSize="10dp" />

    </LinearLayout>

</LinearLayout>

</LinearLayout>

Now its just a image on the left, then 2 textview, Now i believe im gonna need 2 string arrys, one for the titles and the 2nd for the details. and i think a 3rd one for the images. Is that right?

 Here some java for my list view

AndroidListViewActivity.java

import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;

public class AndroidListViewActivity extends ListActivity {
   @Override
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

    // storing string resources into Array
    String[] list_array = getResources().getStringArray(R.array.list_array);

    // Binding resources Array to ListAdapter
    this.setListAdapter(new ArrayAdapter<String>(this, R.layout.item, R.id.label, list_array));



    ListView lv = getListView();

    // listening to single list item on click
    lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> parent, View view,
          int position, long id) {


         }
       });
      }
   }

I know that my java is missing adding the details list_array_details. and i dont know how to add it so it populates. Im not yet using the onitemclick yet for my intent’s. However would i determine which one is click and what activity to launch? example. i click list item b and want to like activity “b” but when i click a it launches activity “a”

Any help would be greately appreciated, Thanks in advance.

You need to have a custom adapter for this purpose to populate someother view other than a textview or multiple textviews.
