Deleting an Item from Listview by Clicking on ImageView widget

Deleting an Item from Listview by Clicking on ImageView widget - android

I'm trying to delete an item from ListView by Clicking on a picture (imageView). I must do it this way, I've managed to do it by click on the item itself but for this project I'm not allowed to do that.
My Adapter extends BaseAdapter and my TaskListItem extends Relative Layout
I'm using a custom layout xml.
protected void onFinishInflate() {
super.onFinishInflate();
textV = (TextView)findViewById(R.id.textViewTask);
textP = ((TextView)findViewById(R.id.textPriority));
textR = ((TextView)findViewById(R.id.textResponsible));
imageD = ((ImageView)findViewById(R.id.imageDeleteTask));
imageD.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
deleteTask();
}
});
}
and the deleteTask() method:
protected void deleteTask() {
//MainActivity.adapter.clear(position)
Toast.makeText(getContext(), "Task Deleted", Toast.LENGTH_SHORT).show();
MainActivity.adapter.notifyDataSetChanged();
}
my problem is the variable position. I cannot find a way to get the position of the item selected (by clicking on the imageView widget).
Finally, here's my adapter code. Any help will be much appreciated:
public class TaskListAdapter extends BaseAdapter {
private ArrayList<Task> tasks;
private Context context;
public TaskListAdapter(ArrayList<Task> tasks, Context context) {
super();
this.tasks = tasks;
this.context = context;
}
#Override
public int getCount() {
return tasks.size();
}
#Override
public Task getItem(int position) {
return (null==tasks)? null: tasks.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TaskListItem tli;
Log.v("test","dasfsd");
if (null == convertView) {
tli = (TaskListItem)View.inflate(context, R.layout.task_list_item, null);
}
else {
tli = (TaskListItem)convertView;
}
tli.setTask(tasks.get(position));
return tli;
}
public void forceReload() {
notifyDataSetChanged();
}
public void clear(int position) {
tasks.remove(position);
}
Update Code for OnClickListener on ImageView
public void setTask(final Task task) {
this.task = task;
//textV.set(task.isComplete());
textV.setText(task.getName());
textP.setText(task.getPriority());
textR.setText(task.getResponsible());
imageD.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// probably get position
// deleteTask();
MainActivity.adapter.notifyDataSetChanged();
}
});
}
protected void deleteTask() {
int position=0;
MainActivity.adapter.clear(position);
Toast.makeText(getContext(), "Task Deleted", Toast.LENGTH_SHORT).show();
MainActivity.adapter.notifyDataSetChanged();
//testing - problem cannot delete item.
}

To get position , Add position as Tag of view
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TaskListItem tli;
Log.v("test","dasfsd");
if (null == convertView) {
tli = (TaskListItem)View.inflate(context, R.layout.task_list_item, null);
}else {
tli = (TaskListItem)convertView;
}
tli.setTask(tasks.get(position) , position);
return tli;
}
public void setTask(final Task task , int position) {
this.task = task;
//textV.set(task.isComplete());
textV.setText(task.getName());
textP.setText(task.getPriority());
textR.setText(task.getResponsible());
imageD.setTag(new Integer(position));
imageD.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int position = (Integer) v.getTag();
deleteTask(position);
MainActivity.adapter.notifyDataSetChanged();
}
});
}
protected void deleteTask(int position) {
MainActivity.adapter.clear(position);
Toast.makeText(getContext(), "Task Deleted", Toast.LENGTH_SHORT).show();
MainActivity.adapter.notifyDataSetChanged();
//testing - problem cannot delete item.
}

How to change text of child view onclick of recycler view?

I have it clicked and it gets up to it and shows the right getText() method but the setText method is not working...

Here is the adapter class:

#Override

}
}

your dbUsersList is not updating. please check your user object in dbUsersList after notify data set change.

What ended up being the problem is that I had passed in the followingList, so I never re-called to grab the new following from the db on update. The update was happening I just had to re-grab the followingList from the db to have an updated list to check against like so in a new method that was passing the list back to the contains method.
db.grabFollowersList();

Set text to TextView at a particular position inside a ListView

I am using a ListView with a custom Adapter. I have two TextView inside each row. I need to change the text of these TextView only for the textViews which I click. How can I achieve it?
I have a method inside my CustomAdapter where I initialise the TextView's
public class MainListAdapter extends BaseAdapter {

showResult.setVisibility(View.VISIBLE);
//set text here based on the position
showResult.setText("SENDING");
}
#Override

int post = position[0];
int respCode = 0;
//perform my network operations
return respCode;
}
#Override

switch(response) {
case 1:
//set text here
showResult.setText("SENT");
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
showResult.setVisibility(View.GONE);
itemName.setVisibility(View.VISIBLE);

break;
case 2:
//set text here
showResult.setText("PLEASE WAIT!");
handler = new Handler();
handler.postDelayed(new Runnable() {

}
}, 2000);
break;
default:
break;
}
}
}
}
Now I need to change the itemName and showResult's text based on the position where the user clicks. The itemName.setOnClickListener has the AsyncTask where I will changing the text of these textViews.
Currently it changes for the last row of the listView.
How do I change it for the position selected.
Thanks in advance.

Override the getView(...) function of CustomAdapter,where one of the arguments is int position .
Don't forget to use convertView, holder and settag/gettag for smooth scrolling and correct references
Update:
in getView put:
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//perform update on textView here
}
});
Also we need reference of convertView in postExecute(). You can pass this reference in AsycTask arguments or set getter setter for the adapter and get clicked reference in asyctask postexecute()

create a model(POJO) class first
with your two strings and one boolean value call it as isChecked
add getters and setters to it
set values(list data) to your arraylist and keep setIsChecked value to false for the first time. like this
ArrayList<model> list = new ArrayList<model>();
list.add(new model("string1","string2",false);
list.add(new model("string11","string22",false);
and so on
now onItemClickListener use for loop like this
for(int i = 0 ; i < list.size; i++){
list.get(i).setIsChecked(false);
}
list.get(itemClickedPosition).setIsChecked(true);
youradapter.notifyDataSetChanged();
after that now come to the adapter class where you can set the selected textview as you want do like this
in getView method do this
if(list.get(position).getIsChecked()){
change your textview
}else{
leave as it is
}
done let me know if it helps you

Pass View in Async Task and then convert into textView and SetText in DoInBackground Method.
new PushTask().execute(v);
#Override
protected Integer doInBackground(final View position) {
runOnUiThread(new Runnable() {
public void run() {
// some code #3 (Write your code here to run in UI thread)
TextView txtName=(TextView)position;
txtname.setText(“android”):
}
});
}

How do I get a reference to the layout of the specific row I was touching?

I've created a custom adapter. Now, I would like to fade out a specific row layout when the user clicks the "cancel" button. The problem is I get only the last row created to fade out and not the row I was actually pressing in:
public class SwipeableRequestsAdapter extends SwipeAdapter {
private final Context ctx;
private final Followers[] values;
private final Typeface roboto;
private ImageView check;
private ImageView cancel;
private SwipeLayout swipeLayout;
public SwipeableRequestsAdapter(Context context, Followers[] items) {
ctx = context;
values = items;
roboto = Typeface.createFromAsset(ctx.getAssets(), "roboto_thin.ttf");
}
#Override
public int getSwipeLayoutResourceId(int position) {
return R.id.swipe;
}
#Override
public View generateView(int i, ViewGroup viewGroup) {
return LayoutInflater.from(ctx).inflate(R.layout.grid_item, null);
}
#Override
public void fillValues(int i, View view) {
swipeLayout = (SwipeLayout) view.findViewById(R.id.swipe);
swipeLayout.addSwipeListener(new SwipeLayout.SwipeListener() {
#Override
public void onClose(SwipeLayout swipeLayout) {
}
#Override
public void onUpdate(SwipeLayout swipeLayout, int i, int i2) {
}
#Override
public void onOpen(SwipeLayout swipeLayout) {
}
#Override
public void onHandRelease(SwipeLayout swipeLayout, float v, float v2) {
}
});
TextView requestText = (TextView) view.findViewById(R.id.sender);
requestText.setTypeface(roboto);
TextView requestPhone = (TextView) view.findViewById(R.id.phone);
requestPhone.setTypeface(roboto);
requestPhone.setText(values[i].getNumber_sender());
TextView currentState = (TextView) view.findViewById(R.id.currentState);
currentState.setTypeface(roboto);
TextView stateTitle = (TextView) view.findViewById(R.id.state);
stateTitle.setTypeface(roboto);
String state = values[i].getState();
if (state.equals("0")) {
currentState.setText("Pending");
} else if (state.equals("1")) {
currentState.setText("Accepted");
} else if (state.equals("2")) {
currentState.setText("Rejected");
} else if (state.equals("3")) {
currentState.setText("Track Back");
}
check = (ImageView) view.findViewById(R.id.approve);
check.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
scaleEffect(v);
Toast.makeText(ctx, "Approved", Toast.LENGTH_SHORT).show();
}
});
cancel = (ImageView) view.findViewById(R.id.trash);
cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
scaleEffect(v);
swipeLayout.animate().alpha(0f).setDuration(150).start();
Toast.makeText(ctx, "Canceled", Toast.LENGTH_SHORT).show();
}
});
}
#Override
public int getCount() {
return values.length;
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return position;
}
private void scaleEffect(final View view) {
view.setScaleX(1.5f);
view.setScaleY(1.5f);
new Thread(new Runnable() {
#Override
public void run() {
try {
Thread.sleep(100);
view.post(new Runnable() {
#Override
public void run() {
view.setScaleX(1f);
view.setScaleY(1f);
}
});
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
}
}

Yes!!! I've found the solution!
All I had to do was to climb up the view hierarchy - inside the list item I already set a button listener:
cancel = (ImageView) view.findViewById(R.id.trash);
cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {}
But now that I have the reference for that specific button through the View passed to the onClick - "v", I can ask to get it's parent view. Anyway, the complete code looks like this:
cancel = (ImageView) view.findViewById(R.id.trash);
cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
scaleEffect(v);
LinearLayout a = (LinearLayout) v.getParent();
SwipeLayout parent = (SwipeLayout) a.getParent();
parent.animate().alpha(0f).setDuration(300).start();
Toast.makeText(ctx, "Canceled", Toast.LENGTH_SHORT).show();
}
});

Progress dialog not showing in button click event in listview

I have a button in each list item of list view. In that button click event i have some codes to run. In click event im showing the progress dialog before the code runs. but its not getting shown. After all the codes in click event completes in the end progress dialog gets shown. Plz help me.
#Override
