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:
package...;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import android.app.Activity;
import android.content.Context;

public class SubAdapter extends BaseAdapter {

private static final int thumb_hight = 128;

private static LayoutInflater inflater = null;
private final String group_id_;
private final Activity activity;
private final SubAdapter t = this;
// used to keep selected position in ListView
private int selectedPos = -1; // init value for not-selected
public SubAdapter(Activity a, final String group_id) {
Drawable d = a.getResources().getDrawable(R.drawable.ic_contact_picture);
default_thumb = ((BitmapDrawable) d).getBitmap();
activity = a;
group_id_ = group_id;
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(int idx, View convertView, ViewGroup parent) {
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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".GroupActivity" >
<ListView

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"

<ImageView

android:layout_alignParentTop="true"
android:layout_margin="6dp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"

android:layout_toRightOf="#+id/imageView1"
android:text="some text"

<TextView

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"
android:layout_alignParentTop="true"
android:layout_margin="6dp"
android:text="present" />
</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.

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"

</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.
I am using ListView with a custom ArrayAdapter, and everything is working fine when I run my app in AVD emulator, but when I install it on my phone my app crashes when I touch any ListView item.

In some previous version of the app I used ListView in the same way on my phone without any problems, and now it is causing my app to crash.
Any idea why this is happening?
I used USB debugging, and found NullPointerException in logcat. It was thrown in getItemId method of my custom adapter, because my entities had null value for id field in database, for some reason. I defined id fields by using ORMLite with:
#DatabaseField(generatedId = true)
private Long id;
I changed type of id fields from Long to int and reinstalled app on phone and it worked, id fields were populated.
I have a listView that's being populated with my existing database in my android app and above that listView, I have a searchView so that I can type in something and then query the database and then display those results in the listView. And at first before I type in anything I have it where it just displays me all items in my database. But when I put in something into the searchView for which it won't provide me any results and I click on the empty screen, the screen crashes, but it should not do that. I instead want to be able to click on it all I want but also display a message saying NO RESULTS FOUND. Also when I clear the searchView, I would like my original results, all the items to display again. I've posted my code below, so any help would be great.

First, create a plain textview in the xml file with the message you want for your activity.
Then try adding this:
listView.setEmptyView(findViewById(R.id.___);
Fill in the ___ part in this line with the id for the textview you created.
Well, I am not sure what is up. I've been through many SO "answers" without any results. I have a custom adapter running on my listview. I want to be able to click on the list item to "see more" but I cannot even get the click to register.
Here is my activity:

import java.util.List;

What am I missing?

EDIT:
What I'd like to do is show the Title from the XML, then show the other XML fields onClick of the XML title from the listview...
Maybe your custom Views in ListView has clickable items and consume click event?
Make sure your ListView has the focus and there are no other clickable items that could steal the click events.
Well I cannot be 100% sure why it is working now, however, I think it has to do with going back through my XML and making sure nothing was missing or even a bit off according to Eclipse.
Thanks for all the comments.
For future folks: CHECK YOUR XML.
I am developing the program that used ListActivity. So, when i scroll the listview to down, it cause to restart application and start from first activity. My code is as follows :
package com.daarkoob.food;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.Window;
import java.util.ArrayList;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.graphics.Typeface;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
public class FoodListActivity extends ListActivity {
private ArrayList<Food> M_foods = new ArrayList<FoodListActivity.Food>();
#Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.foodlist);
SQLiteDatabase sqliteDatabase = SQLiteDatabase.openOrCreateDatabase(
"/data/data/" + this.getPackageName() + "/data.db", null);
Cursor cursor = sqliteDatabase.rawQuery("SELECT * FROM FOOD", null);
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
M_foods.add(new Food(cursor.getString(2), cursor.getString(1)));
cursor.moveToNext();
}
FoodAdapter adapter = new FoodAdapter(this);
setListAdapter(adapter);
cursor.close();
sqliteDatabase.close();
}
public class Food {
public Food(String foodName, String foodType) {
this.M_foodName = foodName;
this.M_foodType = foodType;
}
String M_foodName;
String M_foodType;
}
public class FoodAdapter extends ArrayAdapter<Food> {
private Context M_context = null;
public FoodAdapter(Context context) {
super(context, R.layout.foodlist_view_item, M_foods);
this.M_context = context;
}
#Override
public View getView(final int position, View convertView,
ViewGroup parent) {
if (convertView == null) {
LayoutInflater layoutInflater = (LayoutInflater) M_context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(
R.layout.foodlist_view_item, parent, false);
}
TextView textView = (TextView) convertView
.findViewById(R.id.foodlist_view_item_textview);
textView.setText(M_foods.get(position).M_foodName);
return convertView;
}
}
}
And the foodlist_view_item.xml is :
<?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:background="#drawable/border"
android:orientation="vertical" >
<TextView
android:id="#+id/foodlist_view_item_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:gravity="right|center_vertical"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#android:color/black"
android:textStyle="bold" />
</RelativeLayout>
and the foodlist.xml is as follows :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background"
android:orientation="vertical" >
<TextView
android:id="#+id/foodlist_title_bar"
android:layout_width="match_parent"
android:layout_height="40dip"
android:background="#drawable/textlines"
android:gravity="right|center_vertical"
android:text="#string/foodlist_titlebar_text"
android:textAppearance="?android:attr/textAppearanceLarge" />
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#android:color/transparent"
android:dividerHeight="1dip" >
</ListView>
</LinearLayout>
What thing is wrong ? Why restarting occurs ?
Thanks in advance :)
