The Listview is displaying some rows instead of all items (sometimes, it's displaying nothing), I couldn't understand why this is happenning. It occurs at first run. After that, it works well, with all items from database filled on the screen. I put vertical orientation in my linear layout xml files and wrap_content height. But the problem is not solved.
This is my main activity :
public class MainActivity extends Activity {
public static final String PREFS_NAME = "MyPrefsFile1";

Sometimes height ListView calculate incorrect.
Android: wrap_content is not working with ListView
You can use one adapter and one ListView instead of Two ListViews. Use types for items in this adapter. In this way you can remove wrap_content and set match_parent for height attribute in ListView

I have used a code inside my adaptor class to implement on item click.. Check this code
public class LazyAdapter extends BaseAdapter {
private VideoActivity mainactivity;
private String[] result,imageId,title;
private static LayoutInflater inflater=null;
Context context;
public LazyAdapter(VideoActivity mainactivity, String[] videourls, String[] imgurls, String [] explist) {
context = mainactivity;
result = videourls;
imageId=imgurls;
title = explist;
inflater = (LayoutInflater)mainactivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// imageLoader=new ImageLoader(mainactivity.getApplicationContext());
}
public int getCount() {
return title.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public class Holder
{
TextView tv;
ImageView img;
}
public View getView(final int position, final View convertView, ViewGroup parent) {
Holder holder=new Holder();
View rowView;
rowView = inflater.inflate(R.layout.listview, null);
holder.tv=(TextView) rowView.findViewById(R.id.textView1);
holder.img=(ImageView) rowView.findViewById(R.id.imageView1);
Glide.with(context)
.load(imageId[position])
.into(holder.img);
holder.tv.setText(title[position]);
// imageLoader.DisplayImage(result[position], holder.img);
rowView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// Toast.makeText(context, "You Clicked "+title[position], Toast.LENGTH_LONG).show();
Intent intent = new Intent(context, VideoActivity2.class);
intent.putExtra("imgid",title[position]);
intent.putExtra("videourl",result[position]);
context.startActivity(intent);
}
});
return rowView;
}
}
In this code I also have added a code to pass data on clicking each item in the list view.. Hope this one helps you
I have an app which uses listview to show data received from a JSON.Now, I want an onItemclick listener in the listview so that, after displaying the listview users can click on any row to start a new activity. But the onclicklistener is not working.I am a new developer so am unable to make it work. Kindly help me so that I can implement the onclick Listener. Thanks in advance.
Edited:- Another problem I am facing is that switch case doesnt seem to work because I don't know how many ids will be added to the rows i.e the rows are unknown to me, it may be anything. So what should I use instead of switch case?
Thanks in advance

I have built an android application which displays in Listview style and on clicking on them, shows their respective cost.
Below is the code of that. Hope, it helps you...
public class ListViewActivity extends AppCompatActivity {
private static ListView lv;
private static String[] prod_names = new String[] {"E", "G", "E2", "G2", "X"};
private static int[] cost = new int[] {6500, 13000, 7500, 16000, 25000};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_view);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Listener();
}
public void Listener(){
lv = (ListView)findViewById(R.id.listView);
ArrayAdapter <String> adp = new ArrayAdapter<String>(this, R.layout.products_list, prod_names);
lv.setAdapter(adp);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String val = (String)lv.getItemAtPosition(position);
Toast.makeText(ListViewActivity.this, " Release# : "+ (position+1)+"\n Model : "+val+"\n Cost : Rs "+cost[position], Toast.LENGTH_LONG).show();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_list_view, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Do it like this in your onItemClick:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent newActivity = new Intent(StatementsActivity.this, MainActivity.class);
// Adding your variable to intent
newActivity.putExtra("position",position);
startActivity(newActivity);
break;
}
});
In your MainActivity.java :
public class MainActivity extends Activity
{
int position;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Receiving your variable in another activity
position = getIntent().getIntExtra("position",0);
}
}

Addactivty.java add database class
public class AddActivity extends Activity implements OnClickListener {
private Button btn_save;
private EditText edit_first,edit_last;
private DbHelper mHelper;
private SQLiteDatabase dataBase;
private String id,fname,lname;

alertBuilder.setTitle("Invalid Data");
alertBuilder.setMessage("Please, Enter valid data");
alertBuilder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {

Create Custom Array Adapter like this
public View getView(int position, View convertView, ViewGroup parent) {
View vi=convertView;
if(convertView==null)
vi = inflater.inflate(R.layout.inflatelistview, null);
TextView text=(TextView)vi.findViewById(R.id.textView1);
ImageView image=(ImageView)vi.findViewById(R.id.imageView1);
Button btn=(Button)vi.findViewById(R.id.button1);
btn.setTag(position);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Integer index = (Integer) v.getTag();
//items.remove(index.intValue());
data.remove(position);
notifyDataSetChanged();
}
});
text.setText("item "+position);
imageLoader.DisplayImage(data.get(position), image);
return vi;
}
As you're inserting (Addactivty.java add database class) and fetching (DisplayActivty.java here is listview adding class) data from database similarly you can delete.
For example :
public static boolean Delete(Context context, int id) {
SQLiteDatabase db = new MyDataBase(context).getWritableDatabase();
int res = db.delete(CATEGORY, ID + " = " + id, null);
if (db.isOpen())
db.close();
return (res == 0 ? false : true);
}
You need to delete data from database and listView inside the click listener,like :
mHolder.btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
//1. get the clicked item's *ID*
// (as you did id.get(pos), in your adapter class).
//2. delete data from database using this *ID*.
// (see above function).
//3. remove position from your list.
// list.remove(position);
// (in your case you've multiple lists remove position from all)
//4. notifyDataSetChanged();
}
});
Helping link :
notifyDataSetChanged();
Your choices are:
Use the functions of the ArrayAdapter to modify the underlying List (add(), insert(), remove(), clear(), etc.)
Re-create the ArrayAdapter with the new List data. (Uses a lot of resources and garbage collection.)
Create your own class derived from BaseAdapter and ListAdapter that allows changing of the underlying List data structure.
Use the notifyDataSetChanged() every time the list is updated. To call it on the UI-Thread, use the runOnUiThread() of Activity. Then, notifyDataSetChanged() will work.
Trying to get this working... it loads up fine, even tells the application that it completed getting all the data. It does not populate the listview though.

Just in case it could be an issue with the layout [main.xml]:

android:layout_height="fill_parent">
<ListView

Don't set fill_parent on the layout_height of the root element of list_row_show.xml layout.
I searched for these issues and tried most of the given answers but my issue is not solved yet.
My Grid view has around 10-12 items and and each item has a ImageView and a TextView. image and the texts are dynamically loading from resources.
Issue 1 : When the grid is scrolling the item order changes. first items goes to down and the last items coming to top
Issue 2: When an Admob ad loads in the bottom of the screen entire Grid items are mixing up.Even without any scrolling.
Issue 3: Currently I have put the onClickListeners to the ImageView Only. How do I add the same OnclickListener to the relevant TextView as well
I have used a common gridview generation code found every where in the net.
Here is my code
public class ImageAdapter extends BaseAdapter{
Context myContext;
public ImageAdapter(Context _myContext){
myContext = _myContext;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View MyView = convertView;
try{
if ( convertView == null ){
LayoutInflater li = ((Activity)myContext).getLayoutInflater();
MyView = li.inflate(R.layout.weather_grid, null);
TextView tv = (TextView)MyView.findViewById(R.id.grid_item_text);
Resources res = getResources();
String[] items = res.getStringArray(R.array.weather_items);
final String[] titles = new String[items.length];
int x = 0;
for(String item:items){
titles[x]=item;
x++;
}
// getStringFromRes(titles[position]);
tv.setText(titles[position]);
// Add The Image!!!
final ImageView iv = (ImageView)MyView.findViewById(R.id.grid_item_image);
Class<drawable> resources = R.drawable.class;
Field[] fields = resources.getFields();
String[] imageName = new String[fields.length];
int index = 0;
for( Field field : fields )
{
if(field.getName().startsWith("weather")){
imageName[index] = field.getName();
index++;
}
}
iv.setImageResource(getDrawable(myContext, imageName[position]));
iv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("Clicked Item = " + titles[position]);
Bundle b = new Bundle();
if(titles[position].equals("Weather Overview")){
startActivity(new Intent(WeatherGridActivity.this, WeatherActivity.class));
}
if(titles[position].equals("Current Weather")){
b.putString("display", "current");
Intent intent = new Intent(WeatherGridActivity.this,WeatherActivity.class);
intent.putExtras(b);
startActivityForResult(intent, 0);
//startActivity(new Intent(WeatherGridActivity.this, WeatherActivity.class));
}
if(titles[position].equals("Ask a Question")){
startActivity(new Intent(WeatherGridActivity.this, AskQuestionActivity.class));
}
if(titles[position].equals("Average Temperature")){
startActivity(new Intent(WeatherGridActivity.this, AverageTemperatureActivity.class));
}
}
});
}
}catch(Exception e){
System.out.println("Error Occured = " + e.getMessage());
e.printStackTrace();
}
return MyView;
}

Here is the xml
<?xml version="1.0" encoding="utf-8"?>

</ScrollView>
I have added the RelativeLayout instead of LinerLayout and ScrollViews but now the entire Grid doesn't display but the ads displaying properly.
Here is the new xml
<?xml version="1.0" encoding="utf-8"?>

The xml files has no changes. This works with either RelativeLayout or with a LinearLayout
