I have an XML file: my_form.xml (abridged to just show relevant views). The spinner is populated by a string array from strings.xml
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/LinearLayout01"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<Spinner
android:id="#+id/task"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:entries="#array/task_array"
android:prompt="#string/task" />
<TextView android:id="#+id/addTask"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add another task"
android:onClick="onClick"
android:clickable="true"/>
</LinearLayout>
</ScrollView>
So I have an activity that displays the xml spinner and text view.
When the text view is clicked I want to add another instance of the same xml spinner and text view, so that a person can add as many tasks as they like.
I dont want a multi-select listView as I am going to have to associate each chosen item/task with other individual methods
Can anyone help me please?
public class MyFormActivity extends FragmentActivity implements
OnClickListener {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_form);
final Spinner spinnerTask = (Spinner) findViewById(R.id.task);
ArrayAdapter<CharSequence> adapter_task = ArrayAdapter
.createFromResource(this, R.array.task_array,
android.R.layout.simple_spinner_item);
spinnerTask.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View v, int pos,
long row) {
int taskChoice = spinnerTask.getSelectedItemPosition();
SharedPreferences sharedPref = getSharedPreferences("FileName",
0);
SharedPreferences.Editor prefEditor = sharedPref.edit();
prefEditor.putInt("taskChoiceSpinner", taskChoice);
prefEditor.commit();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
View tvAddTask = (TextView) findViewById(R.id.addTask);
tvAddTask.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Here I want add another instance of the spinner and text view above
}
}
Try this
1 - Edit my_form.xml to this
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/LinearLayout01"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
2 - Create new layout xml file text_view.xml and put this in it
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add another task"
android:clickable="true"/>
3 - Create new layout xml file spinner_view.xml and put this in it
<Spinner xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:entries="#array/task_array"
android:prompt="#string/task" />
4 - Edit your code like this
public class MyFormActivity extends FragmentActivity implements OnClickListener {
private LinearLayout linear;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_form);
linear = (LinearLayout) findViewById(R.id.LinearLayout01);
addNewView();
}
private void addNewView(){
Spinner spinnerTask = View.inflate(this, R.layout.spinner_view, null);
TextView tvAddTask = View.inflate(this, R.layout.text_view, null);
linear.addView(spinnerTask);
linear.addView(tvAddTask);
spinnerTask.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View v, int pos,
long row) {
int taskChoice = pos;
SharedPreferences sharedPref = getSharedPreferences("FileName",
0);
SharedPreferences.Editor prefEditor = sharedPref.edit();
prefEditor.putInt("taskChoiceSpinner", taskChoice);
prefEditor.commit();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
tvAddTask.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Here I want add another instance of the spinner and text view above
addNewView();
}
});
}
}
Hope this helped you.
You could just write a method that would call the spinner and this method would get called in the spinner.setOnItemSelectedListener();

Main activity contains a spinner and a button. MainActivity.java code is as follows.
public class MainActivity extends AppCompatActivity implements LoadNew.VCallback {
public Spinner dropdown;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dropdown = (Spinner) findViewById(R.id.spinner1);
//Create a list of items for the spinner.
String[] items = new String[]{"select topic", "topic1", "topic2"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, items);
dropdown.setAdapter(adapter);
dropdown.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
// TODO Auto-generated method stub
String sp1 = String.valueOf(dropdown.getSelectedItem());
if (sp1.contentEquals("select topic")) {
loadFun("");
}
if (sp1.contentEquals("topic1")) {
loadFun("topic1");
}
if (sp1.contentEquals("topic2")) {
loadFun("topic2");
}
}
#Override
public void onNothingSelected(AdapterView<?> parentView){
// TODO Auto-generated method stub
}
});
Button x = (Button) findViewById(R.id.full_screen);
x.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loadFun("topic2", 0);
}
});
}
public void loadFun(String topicName, int i) {
LoadNew st = new LoadNew(this);
st.display(topicName, i);
}
}
The xml layout for main activity is as follows (activity_main.xml).
<?xml version="1.0" encoding="utf-8"?>

There is another java class LoadNew.java as follows.
public class LoadNew {
public interface VCallback {
//To access methods of MainActivity class
}
public Activity activity;
public LoadNew(Activity _activity) {
this.activity = _activity;
VCallback callerActivity = (VCallback) activity;
}
//Display PDF
public void display(String topicName, int i) {
LinearLayout fullScreen = (LinearLayout) this.activity.findViewById(R.id.full_view);
fullScreen.removeAllViews();//Clear field
LayoutInflater inflater = (LayoutInflater) this.activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.activity_load, null);
if(i ==0) {
this.activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
this.activity.setContentView(view);
}
TextView tv= (TextView) this.activity.findViewById(R.id.tv1);
tv.setText(topicName);
tv.setTextSize(100);
}
}
The activity_load.xml file is as follows.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout> xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"

<TextView
android:id="#+id/tv1"
android:layout_below="#+id/bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</RelativeLayout>
When an item is selected in the spinner, the corresponding text is displayed in the textview. Upon pressing the button, the textview appears in full screen mode.
Now I want to return to the previous view (by pressing back button or by single tab on screen), i.e., the view before the button was clicked. How can I achieve this? Thanks in advance for the patience and the help.
Simplest would be to have the spinner and the non-fullscreen TextView on one activity and open a second activity with the fullscreen mode on button click.
How can I catch onClick events in multiple child views of a list item in a ListFragment with custom Adapter?
I want the onClick event to return the item id and the child view id.
My list item layout is.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:id="#+id/event_status" />
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="7dp"
android:nestedScrollingEnabled="false">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textAppearance="?android:attr/textAppearanceMedium"
android:id="#+id/event_members" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textAppearance="?android:attr/textAppearanceMedium"
android:id="#+id/event_date"/>
</LinearLayout>
</LinearLayout>
I want to catch clicks on event_status and event_members separately.
I personnaly use android left side menu, which manages different fragments by clicking on a custom adapter
https://developer.android.com/training/implementing-navigation/nav-drawer.html
I think the interesting part for you is
myList.setOnItemClickListener(new myItemClickListener());
then
private class myItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// your code
}
}
Hope this can help
You can do it like this
private class YourAdapter extends ArrayAdapter<...>
{
TextView event_date = (TextView) convertView.findViewById(R.id.event_date);
event_date.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
TextView event_members = (TextView) convertView.findViewById(R.id.event_members );
event_date.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
What might also work, but I think there is no benefit in doing it like this and seems not clean:
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// the same two handler here
TextView event_members = (TextView) convertView.findViewById(R.id.event_members );
event_date.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
I have a spinner within alert dialog. I wanted to reduce padding between spinner items and hence I implemented following:
spinner_row.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="30dp"
android:background="#fff" >
<TextView
android:id="#+id/tvCust"
android:layout_width="200dp"
android:layout_height="30dp"
android:gravity="left|center_vertical"
android:textColor="#000"
android:textSize="15sp" />
<RadioButton
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_alignParentRight="true" />
</RelativeLayout>
Activity code contains following:
spinner= (Spinner) dialog.findViewById(R.id.spinner);
String arr[] = { "1", "2", "3" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
CameraActivity.this, R.layout.spinner_row, R.id.tvCust,arr);
spinner.setAdapter(adapter);
Now as you can see in below screenshot, radio button is getting displayed on spinner which is actually a part of spinner_row.xml. Note that textview width is 200dp while spinner is only 130dp long, so that radio button should not have been displayed on spinner. How can I remove it?
Also, when I click any of the spinner item, spinner pop-up doesn't get disappeared as expected.(note all 3 check-boxes are checked in spinner items list). setOnItemSelectedListener is not getting called on item click.
Any help appreciated.
Edit 1
As per farrukh's suggestion, I tried his code and following is the result.

thanks
So the button is in R.layout.user? If so I think you may need to extend SimpleCursorAdapter and in the getView() method you can find the view and add the listener. Something like this:
public class MyCursorAdapter extends SimpleCursorAdapter {
public MyCursorAdapter(...) {
super(...);
}
public void getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
Button button = (Button) view.findViewById(R.id.???);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
...
}
});
}
}
That way your 'find' is scoped to one row in the list. You can't add the listener where you have the code currently because there will be multiple Views with the same ID.
to define onClick to more than one object , your class should implement the interface OnClickListener , and override the method onClick(View v) , like this :
public class MyActivity extends Activity implements OnClickListener{
#Override
public void onCreate(Bundle savedInstance){
....
//add listeners to your buttons
btn1.setOnClikListener(this);
btn2.setOnClickListener(this);
....
}
#Override
public void onClick(View v ) {
if(v==btn1)
// treatement 1
if(v== btn2)
//treatment 2
...etc
}
friends,
i have created very simple custom listview adapter with ratingBar in it.
now i have noticed one thing i cannot rate those rating bars in listview because
when i click on listview that row particular row gets selected.
any one guide me how to select individual items in android listview?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"

any help would be appreciated.
Dear UMAR
In order to implement the listeners to the each element to the listview(Single row) use Custom adapter and in the getview(....) method of the custom adapter ,implements the listeners which u want.. sample code `public class FindFriendsListAdapter extends BaseAdapter {
private ArrayList<SingleElementDetails> allElementDetails;
private LayoutInflater mInflater;
private Context context;
private String userid1;
private int usersno1;
private DBAdapter db;
public FindFriendsListAdapter(Context context, ArrayList<SingleElementDetails> results,String userid,int usersno) {
this.context=context;
this.userid1=userid;
this.usersno1=usersno;
allElementDetails = results;
mInflater = LayoutInflater.from(context);
db=new DBAdapter(context);
db.open();
}
public int getCount() {
return allElementDetails.size();
}
public Object getItem(int position) {
return allElementDetails.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent)
{
convertView = mInflater.inflate(R.layout.friendlisthelper, null);
ImageView imageview = (ImageView) convertView.findViewById(R.id.friendimageview);
TextView textview = (TextView) convertView.findViewById(R.id.friendtextview);
Button button=(Button)convertView.findViewById(R.id.friendbutton);
convertView.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
//do what u want
}
});
button.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
// do what u want
}
});
return convertView;
}
}
`
android:isIndicator="false" in order to rate it. and listview selection will be gone automatically and control will be transferred to that rating control.
Try this
ListView lv_party;
lv_party.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, final int position,long id)
{
// TODO Auto-generated method stub
view.findViewById(R.id.btn_del).setOnClickListener(new View.OnClickListener(){
//your code
}
