setOnItemClickListener on custom ListView

Question

I have a custom ListView. This ListView contains 1 Image and 6 TextViews. To retrieve the value I have created a setOnItemClickListener(...). Whenever I click on the ListView how could I actually retrieve all the data from the 6 TextViews?

Answer 1

Sample Code:

ListView list = (ListView) findViewById(R.id.listview);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
      Object listItem = list.getItemAtPosition(position);
   } 
});

In the sample code above, the listItem should contain the selected data for the textView.

I too had that same problem.. If we think logically little bit we can get the answer.. It worked for me very well.. I hope u will get it..

1. listviewdemo.xml

   <ListView
       android:id="@+id/listview"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:paddingBottom="30dp"
       android:paddingLeft="10dp"
       android:paddingRight="10dp" />
   

2. listviewcontent.xml - note that TextView - android:id="@+id/txtLstItem"

   <LinearLayout
       android:id="@+id/listviewcontentlayout"
       android:layout_width="0dp"
       android:layout_height="fill_parent"
       android:layout_weight="1"
       android:orientation="horizontal">
   
       <ImageView
           android:id="@+id/img1"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_marginRight="6dp" />
   
       <LinearLayout
           android:layout_width="0dp"
           android:layout_height="fill_parent"
           android:layout_weight="1"
           android:orientation="vertical">
   
           <TextView
               android:id="@+id/txtLstItem"
               android:layout_width="match_parent"
               android:layout_height="wrap_content"
               android:gravity="left"
               android:shadowColor="@android:color/black"
               android:shadowRadius="5"
               android:textColor="@android:color/white" />
   
       </LinearLayout>
   
       <ImageView
           android:id="@+id/img2"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_marginRight="6dp" />
   </LinearLayout>
   

3. ListViewActivity.java - Note that view.findViewById(R.id.txtLstItem) - as we setting the value to TextView by setText() method we getting text from TextView by View object returned by onItemClick method. OnItemClick() returns the current view.

   TextView v=(TextView) view.findViewById(R.id.txtLstItem);
   Toast.makeText(getApplicationContext(), "selected Item Name is "+v.getText(), Toast.LENGTH_LONG).show();**
   

   Using this simple logic we can get other values like CheckBox, RadioButton, ImageView etc.

   ListView List = (ListView) findViewById(R.id.listview);
   cursor = cr.query(CONTENT_URI,projection,null,null,null);
   adapter = new ListViewCursorAdapter(ListViewActivity.this, R.layout.listviewcontent, cursor, from, to);
   
   cursor.moveToFirst();
   
   // Let activity manage the cursor
   startManagingCursor(cursor);
   
   List.setAdapter(adapter);
   List.setOnItemClickListener(new AdapterView.OnItemClickListener() {
           @Override
           public void onItemClick (AdapterView < ? > adapter, View view,int position, long arg){
               // TODO Auto-generated method stub
               TextView v = (TextView) view.findViewById(R.id.txtLstItem);
               Toast.makeText(getApplicationContext(), "selected Item Name is " + v.getText(), Toast.LENGTH_LONG).show();
           }
       }
   );
   

Answer 3

If in the listener you get the root layout of the item (say itemLayout), and you gave some id's to the textviews, you can then get them with something like itemLayout.findViewById(R.id.textView1).
