I am using Toast to display on ListViewItem click but toast is not showing up
I am using the following code where I want to display some text after ListView Item click. But Toast doesnt appear on click. I have used ArrayList to store the List items
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
linear_top_right = new LinearLayout(this);
linear_top_right.setOrientation(LinearLayout.HORIZONTAL);
linear_top_left = new LinearLayout(this);
linear_top_left.setOrientation(LinearLayout.HORIZONTAL);
linear_top = new LinearLayout(this);
linear_top.setOrientation(LinearLayout.HORIZONTAL);
linear_list = new LinearLayout(this);
linear_list.setOrientation(LinearLayout.VERTICAL);
linear_All = new LinearLayout(this);
linear_All.setOrientation(LinearLayout.VERTICAL);
btn_delete = new Button(this);
btn_delete.setBackgroundResource(R.drawable.select_minus);
btn_delete.setWidth(15);
btn_delete.setHeight(15);
btn_add = new Button(this);
btn_add.setBackgroundResource(R.drawable.select_add);
btn_add.setWidth(15);
btn_add.setHeight(15);
linear_top_right.addView(btn_delete);
linear_top_right.addView(btn_add);
chk_select_all = new CheckBox(this);
chk_src_to_dest = new CheckBox(this);
chk_select_all.setText("All");
chk_src_to_dest.setText("SRC to Dest");
linear_top_left.addView(chk_select_all);
linear_top_left.addView(chk_src_to_dest);
listView = new ListView(this);
linear_list.addView(listView);
dataAdapter = new MyCustomAdapter(this, R.layout.row_create_list,
allWordList);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setAdapter(dataAdapter);
linear_top_right.setLayoutParams(new LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));

Add this
android:descendantFocusability="blocksDescendants"
To the root element in xml
When you click on list item the checkbox takes focus. So add the above to the RelativeLayout in xml and re-run the app.
Edit:
Looking closely you already have android:focusableInTouchMode="false" so the above might not work.
Edit 2:
I tried your code with just strings with same layout
public class MainActivity extends Activity
{
LinearLayout linear_top_right,linear_top_left,linear_top,linear_All,linear_list;
Button btn_delete,btn_add;
CheckBox chk_select_all, chk_src_to_dest;
ListView listView;
MyCustomAdapter dataAdapter;
String allWordList[]= {"A","B","C"};
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
if (chk_select_all != null)
chk_select_all.setChecked(false);
}
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
linear_top_right = new LinearLayout(this);
linear_top_right.setOrientation(LinearLayout.HORIZONTAL);
linear_top_left = new LinearLayout(this);
linear_top_left.setOrientation(LinearLayout.HORIZONTAL);
linear_top = new LinearLayout(this);
linear_top.setOrientation(LinearLayout.HORIZONTAL);
linear_list = new LinearLayout(this);
linear_list.setOrientation(LinearLayout.VERTICAL);
linear_All = new LinearLayout(this);
linear_All.setOrientation(LinearLayout.VERTICAL);
btn_delete = new Button(this);
btn_delete.setWidth(15);
btn_delete.setHeight(15);
btn_add = new Button(this);
btn_add.setWidth(15);
btn_add.setHeight(15);
linear_top_right.addView(btn_delete);
linear_top_right.addView(btn_add);
chk_select_all = new CheckBox(this);
chk_src_to_dest = new CheckBox(this);
chk_select_all.setText("All");
chk_src_to_dest.setText("SRC to Dest");
linear_top_left.addView(chk_select_all);
linear_top_left.addView(chk_src_to_dest);
listView = new ListView(this);
linear_list.addView(listView);
dataAdapter = new MyCustomAdapter(this, R.layout.m,
allWordList);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setAdapter(dataAdapter);
linear_top_right.setLayoutParams(new LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
linear_top_right.setGravity(Gravity.RIGHT);
linear_top_left.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
linear_top.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,

This is happening due to the click listerners available in your ListView item (checkbox in this case).
You have to add the below to your Checkboxes (they will work as normal :)),
android:focusable="false"
android:focusableInTouchMode="false"
Similar solution here.

change the context of the toast to:
Toast.makeText(getApplicationContext(),"BETA VERSION",
Toast.LENGTH_LONG).show();
