When I apply OnItemClickListener it does not do any action like intent inside the func not called. I tried toast too but nothing shown on clicking the listView Items.
I also tried OnItemSlectedListener , it also not worked for me.
What is the problem here with this code. ?
Thanks Every One. Issue was with autolink on email and phone, I make their focusable=false but nothing happened.Then I remove it and guess what? Clicklistener also starts working.
The attribute android:clickable="true" in your ListView could be overriding all of click events of its child views, you should probably remove it:
<ListView
android:clickable="true" <!-- Remove this attribute -->
android:id="#+id/listView_emp_directory_xml"
android:layout_below="#id/relatice_layout_header_emp_directory_activity_xml"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
I have a project in which i wanted to set my custom View, not simple Android GridView.
I did that, now i want to set RadioButton for each row.
I saw this
But i could not specify the Boolean Array in this Reply.
Here is my Code.
First Items Layout.
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1"
android:layout_marginTop="30dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Small Text"
android:id="#+id/textView2"
android:layout_x="12dp"
android:layout_y="2dp"
android:textColor="#000"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:textAppearance="?android:attr/textAppearanceLarge"
android:layout_marginLeft="20dp"
android:id="#+id/textView"
android:layout_x="157dp"
android:layout_y="0dp"
android:textColor="#000"/>
<RadioGroup
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/radiogroup"></RadioGroup>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/radioButton"
android:layout_x="302dp"
android:layout_y="0dp"
android:checked="false" />
</AbsoluteLayout>
And simple GridView with a Button.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".DisplayActivity">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:weightSum="1"
android:layout_marginTop="30dp">
<GridView
android:layout_width="wrap_content"
android:layout_height="387dp"
android:id="#+id/gridView"
android:background="#abc"
android:layoutDirection="ltr"
android:choiceMode="singleChoice"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Test"
android:id="#+id/button" />
</LinearLayout>
In my Adapter Class :
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.GridView;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;
import java.util.ArrayList;
import android.widget.RadioButton;
public class CarAdapter extends ArrayAdapter<Car> {
RadioButton radioButton;
RadioGroup radioGroup;
ArrayList<Boolean> booleans = new ArrayList<Boolean>();
public CarAdapter(Context context, int resource, ArrayList<Car> carArrayList, ArrayList<Boolean> mlist) {
super(context, resource, carArrayList);
this.booleans = mlist;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Car car = getItem(position);
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.item_car, parent, false);
}
RadioGroup radioGroup = (RadioGroup)convertView.findViewById(R.id.radiogroup);
radioButton = (RadioButton)convertView.findViewById(R.id.radioButton);
TextView carName = (TextView) convertView.findViewById(R.id.textView2);
TextView carSIM = (TextView) convertView.findViewById(R.id.textView);
carName.setText(car.getName());
carSIM.setText(car.getSIM());
return convertView;
}
RadioButton.OnCheckedChangeListener mListener = new RadioButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
booleans.set((Integer) buttonView.getTag(), isChecked); // get the tag so we know the row and store the status
}
};
}
I tried this in getView Method :
radioButton.setTag(Integer.valueOf(position));
radioButton.setChecked(booleans.get(position));
radioButton.setOnCheckedChangeListener(mListener);
And mListener is :
RadioButton.OnCheckedChangeListener mListener = new RadioButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
booleans.set((Integer) buttonView.getTag(), isChecked); // get the tag so we know the row and store the status
}
};
But it gives me
java.lang.IndexOutOfBoundsException at line `radioButton.setChecked(booleans.get(position));`
Here is Main Activity :
import android.app.Activity;
import android.media.Image;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AbsListView;
import android.widget.Button;
import android.widget.CheckedTextView;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.Toast;
import java.util.ArrayList;
public class DisplayActivity extends Activity {
CarAdapter carAdapter;
Car car;
Car car2;
ArrayList<Car> carArrayList;
GridView gridView;
Button test;
ArrayList<Boolean> booleans;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display);
carArrayList = new ArrayList<Car>();
car = new Car("Davie", "Smith");
car2 = new Car("Enrique", "Wall");
carArrayList.add(car);
carArrayList.add(car2);
booleans = new ArrayList<Boolean>(carArrayList.size());
carAdapter = new CarAdapter(getApplicationContext(), android.R.layout.simple_list_item_checked, carArrayList, booleans);
gridView = (GridView) findViewById(R.id.gridView);
gridView.setAdapter(carAdapter);
test = (Button) findViewById(R.id.button);
test.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (gridView.isItemChecked(gridView.getCheckedItemPosition())) {
String name = (carAdapter.getItem(gridView.getCheckedItemPosition())).getName();
Toast.makeText(getApplicationContext(), "Here is " + name, Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "This is not true", Toast.LENGTH_SHORT).show();
}
}
});
}
}
In your CarAdapter modify this...
public CarAdapter(Context context, int resource, ArrayList<Car> carArrayList, ArrayList<Boolean> mlist) {
super(context, resource, carArrayList);
mlist = this.booleans;
}
to
public CarAdapter(Context context, int resource, ArrayList<Car> carArrayList, ArrayList<Boolean> mlist) {
super(context, resource, carArrayList);
this.booleans= mlist ;
}
You are assigning booleans ArrayList to mlist ArrayList which can be empty and so you are getting IndexOutOfBoundsException..you have to assign mlist to booleans ArrayList
mlist = this.booleans;
should be..
this.booleans = mlist;
in your CarAdapter constructor.

instead of ArrayAdapter<String> adapter=new ArrayAdapter<String>(
this,R.layout.text_view,items);
use this
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1, items);
i tried many reference to this,but didn't get it working.
I have a simplecursoradapter with listview .
I populate textview and a button in each listitem.
I need to perform 2 operations:
1.Button Click
2.Listview Click.
Using onListItemClick my code is running perfect.but i cannot access the button inide the listview to perform(a call).
My code below:
<?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"
android:orientation="vertical">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/btn_call"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:layout_gravity="center_vertical"/>
<TextView
android:id="#+id/jobnumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:textStyle="bold"
android:textColor="#000000"
android:layout_marginRight="50dp"
android:height="30sp"
android:gravity="right" />
<TextView
android:id="#+id/complaintdate"
android:layout_width="257dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#+id/jobnumber"
android:gravity="right" />
</RelativeLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:layout_gravity="center_horizontal"
>
<TextView
android:id="#+id/lbltenantname"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_vertical|center_horizontal">
</TextView>
</LinearLayout>
and other textviews....
list to hold the Listitem...
<?xml version="1.0" encoding="utf-8"?>

my listitemclick which is working perfect
public void onListItemClick(ListView parent, View view, int position, long id)
{
}
all i need is click button inside the listview and perform another activity depending on the data from the particular listview position.
set this custom Adapter to your list view...
Custom Adapter Class
public class CustomAdapter extends BaseAdapter implements OnClickListener {
//song list and layout
private ArrayList<from> from;
private LayoutInflater songInf;
//constructor
public CustomAdapter(Context c, ArrayList<from> arrfrom){
from=arrfrom;
songInf=LayoutInflater.from(c);
}
#Override
public int getCount() {
return from.size();
}
#Override
public Object getItem(int arg0) {
return null;
}
#Override
public long getItemId(int arg0) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LinearLayout songLay = (LinearLayout)songInf.inflate
(R.layout.list_item, parent, false);
TextView tv = (TextView)songLay.findViewById(R.id.from_text);
Button button = (Button)songLay.findViewById(R.id.from_button);
tv.setText(from.get(position));
button.setOnClickListner(this);
return songLay;
}
#Override
public void onClick(View v)
{
// Here is code after button click
}
}
Like the title says, my setOnItemClickListener isn't working. I looked through everything I've seen so far on SO and couldn't find my error.
This is the code:
This is the problematic class. It isn't the main class, but is called from an intent:
package...;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListAdapter;
import android.widget.ListView;
public class GroupActivity extends Activity {
String group_id = "";
Context context;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_group);
context = this;
Intent intent = getIntent();
group_id = intent.getStringExtra("group_id");
Log.i("bla", "Launched GroupActivity for group_id " + group_id);
final SubAdapter adapter = new SubAdapter(this, group_id);
ListView lv = (ListView) findViewById(R.id.listView1);
lv.setClickable(true);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> av, View v, int idx, long lidx) {
Log.i("print here", "blaa " + idx);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
This is the SubAdapter class:

default_thumb = ((BitmapDrawable) d).getBitmap();
activity = a;
group_id_ = group_id;
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override

Log.i("bla2", "getting view with index " + idx);
View vi = convertView;
if (convertView == null) {
vi = inflater.inflate(R.layout.sub_list_item, null);
vi.setClickable(true);
}
TextView tv1 = (TextView)vi.findViewById(R.id.textView1);
TextView tv2 = (TextView)vi.findViewById(R.id.textView2);
ImageView img = (ImageView)vi.findViewById(R.id.imageView1);
tv1.setText("first name" + " " + "last name");
tv2.setText("some date");
// put thumbnail
Bitmap thumb = default_thumb;
img.setImageBitmap(thumb);
Log.i("bla3", "index is " + idx + "selected index is " + selectedPos);
if(selectedPos == idx){
Log.i("bla4", "inside if");
}
return vi;
}
public void setSelectedPosition(int pos){
selectedPos = pos;
// inform the view of this change
notifyDataSetChanged();
}
#Override
public void notifyDataSetChanged() {
super.notifyDataSetChanged();
}
}
This is the activity_group xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusableInTouchMode="false"
android:focusable="false" >
</ListView>
</RelativeLayout>
This is the sub_list_item xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/textView1"
android:layout_below="#+id/textView1"
android:layout_toLeftOf="#+id/toggleButton1"
android:text="more text"
android:textAppearance="?android:attr/textAppearance" />
<ToggleButton

android:layout_width="wrap_content"
android:layout_height="wrap_content"

</RelativeLayout>
Apart from the click listener, everything else seems to work. The SubAdapter opens properly and the list is populated.
Basically what I'm looking for is to get the message "Log.i("print here", "blaa " + idx);" to print - it is the log from the ListView's setOnItemClickListener (look above)
Please let me know if there is any other relevant code missing
Thanks!!!
In your GroupActivity class please add the following code before findViewById method:
now you get the view same and change your code
ListView lv = (ListView) findViewById(R.id.listView1);
to
final View v = inflater.inflate(R.layout.rescuer_no_dialog, null);
ListView lv = (ListView)v.findViewById(R.id.listView1);
You should probably remove the call to
vi.setClickable(true); in your SubAdapter class, because your convertView will consume the click before you onItemClick listener.
Change this
ListView lv = (ListView) findViewById(R.id.listView1);
to
lv = getListView()
Extend ListActivity and declare lv outside methods.
