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

I have an ListView which I have populate with a dynamic ArrayList and I used an OnItemClickListener to make it does something when i click on them (Code bellow).
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,txtOnlyList);
returnSaveNotesList.setAdapter(arrayAdapter);
AdapterView.OnItemClickListener noteClickListener = new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> txtOnlyList, View view, int position, long id) {
if(position == 0 ) {
Intent intent = new Intent(ReadFromFile1.this, SaveAndRstoreNote.class);
intent.putExtra("firstNote","1 .txt");
startActivity(intent);
}
}
};
returnSaveNotesList.setOnItemClickListener(noteClickListener);
Now comes the tricky part, I want, somehow to be able to read what is actually written lets say on the position [0], the actual String. Is there any way to achieve that?
public void onItemClick(AdapterView<?> txtOnlyList, View view, int position, long id) {
if (position == 0) {
String yourString = txtOnlyList.get(position);// use this
Intent intent = new Intent(ReadFromFile1.this, SaveAndRstoreNote.class);
intent.putExtra("firstNote", "1 .txt");
startActivity(intent);
}
}
Your ArrayAdapter<String> has a getItem() method that returns the String for a given position.
I have used the getItemAtPosition(position).
Here is the entire code:
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,txtOnlyList);
returnSaveNotesList.setAdapter(arrayAdapter);
AdapterView.OnItemClickListener noteClickListener = new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> txtOnlyList, View view, int position, long id) {
if(position == 0 ){
Intent intent = new Intent(ReadFromFile1.this, SaveAndRstoreNote.class);
String stringFromArray=txtOnlyList.getItemAtPosition(position).toString(); // I added this
intent.putExtra("firstNote","1 .txt");
startActivity(intent);
}
}
};
returnSaveNotesList.setOnItemClickListener(noteClickListener);
The View type parameter being passed in your OnItemClick function is the list item's view at that position.
AdapterView.OnItemClickListener noteClickListener = new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> txtOnlyList, View view, int position, long id) {
TextView tv = (TextView) view.findViewById(R.id.tv);
String text = tv.getText().toString(); //The required text is available in this variable
}
}
Currently, the code i have only displays the data (on a new activity when clicked) at index 0 of that list view - not the item i actually clicked. i would like to somehow change my code so it can display the data at index n (n being the item i clicked in list view):
ResultsActivity.java
final ArrayList<String> searchResults = getValuesFromJSON(jsonResult);
final ListView listView = (ListView) findViewById(R.id.listView);
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>
(this, android.R.layout.simple_list_item_1, searchResults);
listView.setAdapter(arrayAdapter);
//list items become clickable and open the movie detail page which displays the movie data of the specific movie
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent newActivity = new Intent(ResultsActivity.this, MoviePage.class);
newActivity.putStringArrayListExtra("movie data", searchResults);
startActivity(newActivity);
}
});
}
MoviePage.java
ArrayList<String> searchResults = getIntent().getStringArrayListExtra("movie data");
TextView t = (TextView)findViewById(R.id.textViewfinal);
t.setText(searchResults.get(9));
Just set a onclick listener on your listview so you can listen for item click events.
Put this in your onCreate method in your activity:
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
//you can move the textview to a class variable if you want
TextView t = (TextView)findViewById(R.id.textViewfinal);
t.setText(searchResults.get(position));
}
});
update: you'll want to pass the position to the next activity the same way your passing the searchResults to MoviePage so just do this:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent newActivity = new Intent(ResultsActivity.this, MoviePage.class);
newActivity.putStringArrayListExtra("movie data", searchResults);
newActivity.putExtra("position",position);//pass the position to the next activity
startActivity(newActivity);
}
});
now in MoviePage.java
ArrayList<String> searchResults = getIntent().getStringArrayListExtra("movie data");
int position = getIntent().getIntExtra("position",0);
TextView t = (TextView)findViewById(R.id.textViewfinal);
t.setText(searchResults.get(position));
Try this :
ResultsActivity.java
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent newActivity = new Intent(ResultsActivity.this, MoviePage.class);
newActivity.putExtra("movie data", searchResults.get(position));
startActivity(newActivity);
}
});
MoviePage.java
Bundle extras = getIntent().getExtras();
if (extras != null) {
TextView t = (TextView)findViewById(R.id.textViewfinal);
t.setText(extras.getString("movie data"));
}
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);
have a look here
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.
I have created one listview of some names,what i need is when i will click selected row it will go to that page only,on click on different row it will move to the same class but different content.I think it will move by question id.could anybody help me how to pass the question id Or any other method to do this..
here is my code..
private OnItemClickListener mlist = new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
}
};
You can try something like this -
private OnItemClickListener mlist = new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
if(Some condition)
{
Intent i= new Intent(YourActivity.this,ActivityOne.class);
// To pass data
i.putExtra("SomeId", someValue);
startActivity(i);
}
else if(Some other condition)
{
Intent i= new Intent(YourActivity.this,SecondActivityTwo.class);
startActivity(i);
}
else
{
// Do something else--
}
}
};
And in the other activity -
String identifier = getIntent().getExtras().getString("SomeId");
Here I've given an example assuming you have user list and clicking on item you want to show user profile...
In List_Act activity...
public View getView(int position, View convertView, ViewGroup parent)
{
convertView = mInflater.inflate(R.layout.rowitem,parent,false);
convertView.setTag(UserId);
}
private OnItemClickListener mlist = new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Intent i=new Intent(List_Act.this, Profile_Act.class);
int UserId = ((View)v.getParent()).getTag();
i.putExtra("UserId", UserId); //Setting variable you want to pass to another activity
startActivity(i);
}
};
in Profile_Act activity in onCreate()
String UserId = getIntent().getExtras().getString("UserId"); //retrieving value in another activity
now you'll have UserId variable set and you can use it...
