I know that there are a lot of posts about checkboxes within Listviews and I can honestly say that after reading a large majority of these, it has left me confused with a hurting brain.
My code does not extend the ListViewActivity but does have a listview as part of a relative layout which sits within a tabhost.
I have tried the focusable=false both against the textview and the checkbox, the textview behaves but the checkbox still overrides the focus of the listview item.
If I only needed one textview then I would have gone for androids built in layout but I require at least 6 textviews with a checkox on each line.
My Main.xml is this :
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tabhost_master"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="65px"
/>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="65px">
<RelativeLayout
android:id="@+id/tab1"
android:orientation="vertical"
android:layout_height="fill_parent"
android:weightSum="1" android:gravity="top" android:layout_width="fill_parent">
<TextView android:text="Morning Set Up" android:textAppearance="?android:attr/textAppearanceMedium" android:id="@+id/textView1" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true"></TextView>
<Button android:text="Set Time On" android:layout_height="wrap_content" android:id="@+id/startb" android:layout_width="wrap_content" android:layout_below="@+id/textView1" android:layout_alignParentLeft="true"></Button>

<RelativeLayout

<TextView android:text="A Set Up" android:textAppearance="?android:attr/textAppearanceMedium" android:id="@+id/textView1_a" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true"></TextView>

</RelativeLayout>
</FrameLayout>
</TabHost>
My layout for the listview is this :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<CheckBox android:text="Cancel ?" android:focusable="false" android:checked="false" android:layout_width="wrap_content" android:id="@+id/checkBox1" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true"></CheckBox>
<TextView android:layout_width="wrap_content" android:focusable="false" android:id="@+id/time_disp" android:layout_height="wrap_content" android:text="TextView" android:layout_alignParentTop="true" android:layout_toRightOf="@+id/checkBox1" android:layout_marginLeft="16dp" android:layout_marginTop="15dp"></TextView>
<CheckedTextView android:layout_width="wrap_content" android:focusable="false" android:layout_height="wrap_content" android:text="CheckedTextView" android:id="@+id/checkedTextView1" android:layout_alignTop="@+id/time_disp" android:layout_alignParentRight="true" android:layout_marginRight="18dp"></CheckedTextView>
</RelativeLayout>
My activity code is this :
package co.uk.sheildsatmax.layout_tester;
import android.app.Activity;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
import android.widget.Toast;
import android.widget.CheckBox;
public class Layout_testerActivity extends Activity {
/** Called when the activity is first created. */
private String[] times = {"09:10","10:10","11:20","09:10","12:20","15:30","10:12"};
ListView lv;
CheckBox ticked;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabhost=(TabHost)findViewById(R.id.tabhost_master);
tabhost.setup();
TabSpec tab1 = tabhost.newTabSpec("Tab1");
morning_tab.setContent(R.id.tab1);
morning_tab.setIndicator("Tab1 Setup");
TabSpec tab2 = tabhost.newTabSpec("tab2");
after_tab.setContent(R.id.tab2);
after_tab.setIndicator("Tab2 Setup");
tabhost.addTab(tab1b);
tabhost.addTab(tab2);
lv = (ListView)findViewById(R.id.listView1);
// ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this,R.layout.,R.id.time_disp,times);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.list_lay,R.id.time_disp,times);
lv.setItemsCanFocus(false); // this was another test attempt
lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); // tried this and then realised it needed androids own layout to work
lv.setAdapter(adapter);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplication().getApplicationContext(), "ID :"+Long.toString(arg3), Toast.LENGTH_LONG).show();
}
});
}
}
Now I have been reading about creating a separate class for the adapter to make the checkbox work correctly, but is this required and if so could someone please post a basic example for me to use as all of these links I have read have really confused me:

As you can see I have read quite a few, but they have puzzled me even more and none seem to have examples without listactivies. I am writing this in android 1.6
