android:layout_height="wrap_content">
<LinearLayout

android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
</TabHost>
</LinearLayout>This is my layout xml for tabwidget and the code is
Code:
public class BookListTab extends TabActivity implements View.OnClickListener {
Button homeButton;
@Override
public void onClick(View paramView) {
if(paramView !=null){
Intent intent = new Intent();
intent.setClass(this, GridViewer.class);
startActivity(intent);
}
}
// This class is for list option in the main menu and it list all books read user with tabs
// like books,authors,tag etc and it also has sort option
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
try{
super.onCreate(savedInstanceState);
setContentView(R.layout.booklistview);
homeButton = (Button) findViewById(R.id.button2);
homeButton.setOnClickListener(this);
TabHost tabHost = getTabHost();
tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("TEXT").setContent(new Intent(this, BookActivity.class)));
tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("LIST").setContent(new Intent(this, AuthorActivity.class)));
tabHost.setCurrentTab(1);
}
catch(Exception e){
e.getLocalizedMessage();
}
}Inside BookActivity class , i have code for listview with icons
Code:
public class BookActivity extends ListActivity {
String[] title = new String[] {
"*New*Apple iPad Wi-Fi (16GB)",
"7 Touch Tablet -2GB Google Android",
"Apple iPad Wi-Fi (16GB) Rarely Used ",
"Apple iPad Wi-Fi (16GB) AppleCase" };
static final String[] detail = new String[] { "1h 37m Shipping: $10.00",
"1h 39m Shipping: Free", "58m 6s Shipping: $10.00",
"59m 30s Shipping: $10.95" };
private Integer[] imgid = {
R.drawable.boomerang,R.drawable.garden,R.drawable.index,
R.drawable.kaku
};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bookactivity);
setListAdapter(new MyCustomAdapter(this, R.layout.booklistrow,
title));
getListView().setTextFilterEnabled(true);
}
public class MyCustomAdapter extends ArrayAdapter<String> {
public MyCustomAdapter(Context context, int textViewResourceId,
String[] objects) {
super(context, textViewResourceId, objects);
// TODO Auto-generated constructor stub
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row=null;;
try{
LayoutInflater inflater=getLayoutInflater();
row=inflater.inflate(R.layout.booklistrow, parent, false);
TextView label=(TextView)row.findViewById(R.id.title);
label.setText(title[position]);
ImageView icon=(ImageView)row.findViewById(R.id.img);
// if it is root folder we wont set icon or else we place approprate icons i.e file & folder
}
catch(Exception e){
e.getLocalizedMessage();
}
return row;
}
}
}and the layouts used for listview
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:text="book content"
android:padding="15dip"
android:textSize="18dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<TextView android:id="@+id/path" android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<ListView android:id="@android:id/list" android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<TextView android:id="@android:id/empty" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="No Data" />
</LinearLayout>and this layout to inflate listview
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/img"
android:scaleType="centerCrop"
android:layout_width="70dp"
android:layout_height="70dp"/>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:paddingLeft="10dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<TextView
android:layout_width="fill_parent"
android:id="@+id/title"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textColor="#000000"
android:textSize="16sp" />
</LinearLayout>
</LinearLayout>My problem is tabs are forming correctly but listview is not formed inside tabhost.
Any idea why list view is not showing,any clarification on the code ,you can ask
Thanks
