How do I get each textview resource amount and add them all together into a single variable to be converted into a two sliced pie chart?

This is the code I have been working on for a while. The only issue is I cannot seem to be able to get the sum of values input into the editText fields that are dynamically added into the program and then place them into a pie chart. The data is to be transferred from the second activity to the third where the third activity will add up all resource amounts and display them into a pie chart.

Create an interface class like this;
You can set many kind of information as a parameter about your deleted item and send it to your activity.
public interface ItemSelectedListener{
void onItemSelected(boolean isDeleted);
}
In your adapter initialize your interface;
private List<ItemSelectedListener> mItemSelectedSubscribers = new ArrayList<ItemSelectedListener>();
Add this method in your adapter ;
public void subscribeItemSelection(ItemSelectedListener listener) {
mItemSelectedSubscribers .add(listener);
}
Set this loop in your click events;
tv_delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for (ItemSelectedListener listener : mItemSelectedSubscribers ) {
listener.onItemSelected(true);
}
list.remove(position);
b.setText("Show me~~~~ u r change!!!");
notifyDataSetChanged();
Log.d(TAG, "onClick: What is you?"+list.size());
}
});
In your activity, implement your interface and you will set a implemented methods. this methods look like this;
boolean isDeleted;
#Override
public void onItemSelected(boolean isDeleted) {
this.isDeleted = isDeleted;
}
You know now item is deleted or not. When a button deleted you can change text by using your method.
if(isDeleted){
btn.setText(changeText)
}
Hope this help!

Just ask for more detailed, thanks

Just add tab Layout change listener and hide and show icon according to the requirement.

Navigation is in hidden mode, change it to visible.. it will work

ANdroid not display custom adapter

i work about a vtc app and I need to display on the main screen the orders of the client.
I chose the way of customing the list view with an adapter but when i launch the app nothing on the screen except the title of the page.

I hope you will help me to find the error and if you want more, try to explain me how i can optimize my code. TY

You should call notifyDataSetChanged() in the ResponseListener after filling your list.
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
boolean success = jsonObject.getBoolean("success");
if(success){
int count = jsonObject.getInt("count");
for(int i=0; i<count; i++) {
...
coursesList.add(course);
}
//notify adapter about change in data
coursesAdapter.notifyDataSetChanged();
}else{
NoCommand.setEnabled(true);
NoCommand.setText("Oups... Vous n'avez commandé aucune course pour le moment.");
}
} catch (JSONException e) {
e.printStackTrace();
}

Android how to load image from url and put it on top

Actually I have done the "load from url" part but the result is not satisfying.
I wnat the image placed on the top. However, when it loaded the image, it automatically align to center but I have declared android:layout_alignParentTop="true" .
Besides, I'd like to have some text on the image but the text are always on the top left corner..........
here are my codes:
(xml)
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/list_detail"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ImageView
android:id="#+id/product_image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:src="#drawable/white" />
<TextView
android:id="#+id/product_price"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/product_image"
android:text="#string/hello_world" />
<TextView
android:id="#+id/product_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/product_price"
android:text="#string/hello_world" />
</RelativeLayout>

You should use wrap_content instead match_parent for product_image's android:layout_width, and you should use FrameLayout if you want put text on the ImageView. like:
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:layout_width="wrap_content"
android:src="#drawable/ic_launcher"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:text="test"
android:layout_height="wrap_content" />
</FrameLayout>
