Question

I have a string-array, that i need to display in a layout.
The code currently shows the list, but the list isn’t in the layout, its make a new “screen” where the only thing you can see is the list.

Here’s the code that i just can’t get to show the list in the layouts listview.

import android.app.ListActivity;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class idchart extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.idchart);

    Resources res = getResources();

 // To get the string array associated with particular resource ID.
 String[] ids = res.getStringArray(R.array.idchart_array);
 ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.test_list_item,ids);
 setListAdapter(adapter);
 }

}

layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/bg_main"
android:orientation="vertical" >


<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:src="@drawable/logo" />


<Button
    android:id="@+id/btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button" />

<RelativeLayout
    android:id="@+id/relative"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

    <ListView
        android:id="@+id/lv"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >
    </ListView>
</RelativeLayout>

</LinearLayout>

I haven’t been able to find anything that helped 🙁 so i hope you will be able to.

Answer 1

ListView listView=(ListView)findViewById(R.id.lv);
//rest of code
listView.setAdapter(adapter);

And you can avoid extending ListActivity.

If you are using ListActivity then

ListView listView=getListView();
