I've an Activity containing a basic Listview. The functionality works as follows:
click a listview item -> get the listview item name -> pass the name with intent and start a new activity.
Everything is working except for the start of a new Activity. Its just not responsive and I cannot see why. I would really appreciate an extra pair of eyes to look over this.
listView = getListView();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, foodNames);
listView.setAdapter(adapter);
listView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView parentView, View childView, int position, long id) {
TextView tv = (TextView) listView.getSelectedItem();
String value = tv.getText().toString();
Log.v("DEBUG","Name of item clicked" + value);
Intent intent = new Intent(childView.getContext(), FoodItemActivity.class);
intent.putExtra("FoodName", value );
startActivity(intent);
}
public void onNothingSelected(AdapterView parentView) {
}
});
I think you are missing line
startActivity(intent);
:-)
try it this way:
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent intent = new Intent(view.getContext(), FoodItemActivity.class);
intent.putExtra("FoodName", value );
startActivity(intent);
}
});
this will solve your question, and if still problem arises, then do confirm that all the child controls are focusable=false and clickable=false.

My app is passing text taken from TextView in list item. I know that text in this text views is right cause I can see that it's ok. Text taken from TextView is pid of photo in MySql database.
My onItemClick code :
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (((ImageView) findViewById(R.id.reviewImageView)).getBackground() != null) {
String pid = ((TextView) findViewById(R.id.reviewListPid)).getText().toString();
Intent i = new Intent(getApplicationContext(), photoActivity.class);
i.putExtra("pid", pid);
i.putExtra("database", database_name);
startActivity(i);
}
}
});
I'm sure that text in every list item is right and I can see that text passed to next activity is wrong, cause I can see variable value in log and it's wrong.
Two things:
This won't fix your issue but instead of using getApplicationContext() in your Intent intialization use <YourActivityName>.this instead.
The way you are getting your String is a little unusual, and unnecessary. Most likely, you are loading your adapter for your listview with some sort of array that contains the "pid", correct? So then just get the value from that array in your onItemClickListener callback.
It would look like this:
String[] items = {"..."};
ArrayAdapter<String> itemsAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, items);
listView.setAdapter(itemsAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (((ImageView) findViewById(R.id.reviewImageView)).getBackground() != null) {
String pid = items[position];
Intent i = new Intent(MyActivity.this, photoActivity.class);
i.putExtra("pid", pid);
i.putExtra("database", database_name);
startActivity(i);
}
}
});
I want to get the item on list view to edit Text in another activity.
When clicked on list view item, I want to transfer the item in another activity in edit Text.
You have to make onItemClickListner of listview like that.
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent i = new Intent(getApplicationContext(), SecondActivity.class);
i.putExtra("new_variable_name","value");
startActivity(i);
}
});
Then in the new Activity, retrieve those values:
Bundle extras = getIntent().getExtras();
if (extras != null) {
String value = extras.getString("new_variable_name");
}
And finally set Value to editText like this
editText.setText(value);
Hope this will help you.
lstView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent intent = new Intent(getActivity(), NewActivity.class);
intent.putExtra("text", text want to transfer);
startActivity(intent);
}
});
You can make use of SharedPreferences. And when you pass the content of the ListView to the next activity, you can use editText.setText("Your Text").
You can also pass your data through intents from which you are calling your new activity.
create onClick method like this.
ListView list = (ListView) findViewById(R.id.newsList);
list.setAdapter(adapter);
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long offset) {
NewsItem item = (NewsItem) adapter.getItem(position);
Intent intent = new Intent(getApplicationContext(), NewsDetailsActivity.class);
intent.putExtra(KEY, item.getHeadline());
startActivity(intent);
}
});
In next activity
Intent intent = getIntent();
headline = intent.getStringExtra(KEY);

Hi everyone:
I hope someone can help me here,The Cursor generated by a Query populate the ListView with the Layout defined by simple_list_item_2.
To create the Intent i need the first string of the clicked View but in the String to Go i have something like
android.widget.TextView#411fbfb8
Now the code.
I can't understand where is the error.
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_2, cursor, columns, ids, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
final ListView myList=(ListView)findViewById(R.id.listView1);
myList.setAdapter(adapter);
myList.setClickable(true);
/*
* Click Listener
*/
myList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> l, View v, int position, long id)
{
Log.v("io", "start");
Intent intent = new Intent(MainActivity.this, WorkActivity.class);
View buff = myList.getChildAt(position);
String toGo = buff.findViewById(android.R.id.text1).toString();
Log.v("io",toGo);
intent.putExtra("dname", toGo);
startActivity(intent);
}
} );
try:
String toGo = ((TextView)buff.findViewById(android.R.id.text1)).getText().toString()
inside your onItemClick you can retrieve data linked to your adapter through the AdapterView argument. Calling getItemAtPosition(int) you can access data associated with the selected item
myList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> l, View v, int position, long id)
{
Log.v("io", "start");
Intent intent = new Intent(MainActivity.this, WorkActivity.class);
View buff = myList.getChildAt(position);
String toGo = l.getItemAtPosition(position);
Log.v("io",toGo);
intent.putExtra("dname", toGo);
startActivity(intent);
}
} );
//
myList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> l, View v, int position, long id)
{
Log.v("io", "start");
Intent intent = new Intent(MainActivity.this, WorkActivity.class);
//View buff = myList.getChildAt(position);
// String toGo = buff.findViewById(android.R.id.text1).toString();
String toGo = (TextView)v.getText();
Log.v("io",toGo);
intent.putExtra("dname", toGo);
startActivity(intent);
}
} );
To get the view do as following:
LinearLayout row = (LinearLayout) ((LinearLayout)v);
Or RelativeLayout instead of LinearLayout if that your case
then apply the follwing code to get the text of TextView based on its order:
TextView column = (TextView)row.getChildAt(0);
String text = column.getText().toString();
Hope this help
Hey everyone I've looked for hours trying to find a solution to this, my goal is to have a Listview when it opens well open another activity. Well actually I got it to be able to open another activity when its click but how do I get it so that each list item will open its own activity? I am terribly sorry if this question is already answered but the links I found doesn't really describe what the code is doing [Yes i am a newbie :)]
this is the code im using
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] countries = getResources().getStringArray(R.array.countries_array);
setListAdapter(new ArrayAdapter<String>(this, R.layout.newfile, countries));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Intent myIntent = new Intent(view.getContext(), Html_file.class);
startActivityForResult(myIntent, 0);
}
});
}
}
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
if(position == 1) {
//code specific to first list item
Intent myIntent = new Intent(view.getContext(), Html_file1.class);
startActivityForResult(myIntent, 0);
}
if(position == 2) {
//code specific to 2nd list item
Intent myIntent = new Intent(view.getContext(), Html_file2.class);
startActivityForResult(myIntent, 0);
}
}
});
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
switch( position ) {
case 0: Intent newActivity = new Intent(this, i1.class);
startActivity(newActivity);
break;
case 1: Intent newActivity = new Intent(this, i2.class);
startActivity(newActivity);
break;
case 2: Intent newActivity = new Intent(this, i3.class);
startActivity(newActivity);
break;
case 3: Intent newActivity = new Intent(this, i4.class);
startActivity(newActivity);
break;
case 4: Intent newActivity = new Intent(this, i5.class);
startActivity(newActivity);
break;
}
}
If you have some limited number of list you can use switch case here on position
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Intent myIntent = new Intent(view.getContext(), Html_file.class);
startActivityForResult(myIntent, 0);
}
});
If you know which activity is to be opened when different list items are clicked, then just assign id or tag to the list items.
In the callback of onItemClick, you have a parameter View,
use it to get id or tag to differentiate them and call respective Activity.
// Add ArrayList and ArrayAdapter:
final ArrayList<String> listItems = new ArrayList<String>();
listItems.add("image_one");
listItems.add("image_two");
listItems.add("image_three");
ArrayAdapter<String> myArrayAdapter = new ArrayAdapter<>(this,
android.R.layout.simple_list_item_1, listItems);
myListView.setAdapter(myArrayAdapter);
// Add ArrayList of Classes:
final ArrayList<Class> intents = new ArrayList<Class>();
intents.add(image_one.class);
intents.add(image_two.class);
intents.add(image_three.class);
// Click on list item to open Class from ArrayList of Classes:
myListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int
position, long id) {
Intent listIntent = new Intent(getApplicationContext(),
intents.get(position));
startActivity(listIntent);
}
});

I have created a ListView where I have to add different items. Now, when I click on a particular item it displays another window. On that window, I want to display the name of that item which I click on the ListView.
My code:
private ListView contactList;
private String lv_arr[]={"Android","iPhone","BlackBerry","AndroidPeople"};
#Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.contact_activity);
contactList=(ListView)findViewById(R.id.ListView01);
contactList.setAdapter(new ArrayAdapter<String (this,android.R.layout.simple_list_item_1 , lv_arr));
contactList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
/*Intent myIntent = new Intent(view.getContext(), CallActivity.class);
startActivity(myIntent);*/
}
});
}
you have to get the name of the item on itemclick event. pass it to the activity which will be called. in in the calling activity get the name of item and display
contactList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String selecteditem = lv_arr[position];
Intent myIntent = new Intent(view.getContext(), CallActivity.class);
intent.putExtra("item", selecteditem);
startActivity(myIntent);
}
});
In CallActivity.java
write the following to get the selected item name
String selectedItem=getIntent().getStringExtra("item");
Instead of starting a new activity, use AlertDialog. You already have the position of the list item clicked. So displaying it on the dialog shouldn't be a problem if you follow the article linked.
EDIT :
As per your requirement, you have to launch a new activity to display a string
In the sending list activity
intent.putExtra(String key, String value)
In receiving activity,
String value = getIntent().getStringExtra(key);
