Programmatically loading parse images and text into linear layout

I am trying to create a list of items followed by their name and caloric value in a similar way to the image below.
However I am trying to do this while getting all my data from Parse. I have got it down for the most part but I have been stuck for hours trying to programatically add these two text views and image one after the other (text then view) as I loop through them.
I have been skeptical to make major changes to the code as I am not very proficient with android, however from what I have looked at so far my case seems to be unique in the sense that it involves both Parse and using textviews and imageviews together.
Below is what I've got so far on this activity:

itemCalories.setText(object.getString("calories") + " kcal");
itemCalories.setLayoutParams(new ViewGroup.LayoutParams(

linLayout.addView(itemCalories);
linLayout.addView(itemName);
file.getDataInBackground(new GetDataCallback() {

ViewGroup.LayoutParams.WRAP_CONTENT
));
imageView.setImageBitmap(bitmap);
linLayout.addView(imageView);
}
}
});
}
}
}
});
}
}
Right now what happens is all the text goes to the top and images goes to the bottom. I've also tried doing this:
file.getDataInBackground(new GetDataCallback() {
#Override
public void done(byte[] bytes, ParseException e) {
if (e == null && bytes != null){
Bitmap bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
imageView = new ImageView(getApplicationContext());
imageView.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT
));
imageView.setImageBitmap(bitmap);
linLayout.addView(imageView);
linLayout.addView(itemCalories);
linLayout.addView(itemName);
But then I get this Error:
The specified child already has a parent. You must call removeView() on the child's parent first.
and none of the answers to this error that I found seem to be helpful in this situation.
Long story short, I'm not even looking for something super complex or for it to look good, I am just a beginner. I just want to load the textviews and then the imageview one after the other, just like in the image, while using parse.
Any ideas?

Dynamically created Views don't appear in the GridLayout properly

I have a GridLayout in which I want dynamically generated TextViews to be displayed. At least the GridLayout can have 2 columns and at most it can have 3 columns.
I have a function called decide(int) that passes an integer argument to another function that actually generates the TextViews dynamically. This integer value is then tested to decide the number of columns and rows the GridLayout can have.
Following is my MainActivity.java

return super.onOptionsItemSelected(item);
}
private void init()
{
gridLayout = (GridLayout) findViewById(R.id.gridLayout);
}
public void handleClick()
{
}
private void decide(int num)
{
if((num%3)==0 || (num%2)==0)
generateView(num);
else
{

generateView(num);
}
}
public void generateView(int num)
{
if(((num%3)==0 && (num%2)==0) || (num%3)==0)
{
Toast.makeText(MainActivity.this,"3 has been executed", Toast.LENGTH_SHORT).show();

if(number>1)
{
gridLayout.setRowCount(number);

TextView tv = new TextView(this);
GridLayout.LayoutParams params = new GridLayout.LayoutParams();
params.height = ViewGroup.LayoutParams.WRAP_CONTENT;
params.width = GridLayout.LayoutParams.MATCH_PARENT;
tv.setLayoutParams(params);
tv.setText("HEY THERE!!!");
gridLayout.addView(tv);
}
}
}
And following is my content_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

tools:showIn="#layout/activity_main">
<GridLayout
android:id="#+id/gridLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="129dp">
</GridLayout>
</RelativeLayout>
This is the output I'm getting: -
My app is supposed to generate 6 Hey There!! TextViews, but instead it ends up generating just 2.
Where am I going wrong?
Thank you for your time!!

Make your gridlayout's height to wrap_content.
<GridLayout
android:id="#+id/gridLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="129dp">
</GridLayout>

Found the solution myself.
Changing
params.width = GridLayout.LayoutParams.MATCH_PARENT;
to
params.width = ViewGroup.LayoutParams.WRAP_CONTENT;
did the trick.

I am not receiving any logged input from the EditText in the logcat.
Any hints or help would be very appreciated!

You're using a view that is different from the one that's in the dialog.
Try casting the dialogInterface to Dialog:
taskDescription = (EditText) ((Dialog) dialogInterface).findViewById(R.id.task_description);

Form displays nothing when debugging android in Eclipse

The form for viewing has textviews, a listview and a button, but it only display a white blank form during debugging.

The display of the xml file for Expense_Calendar.java displays just fine during debugging, but upon "if(convDate1.equals(convDate2))" condition is true, the form view_date_e.xml displays next should have some textviews, a listview and a button displaying, but it only displays a blank form.
Any help would be greatly much appreciated

android - Toolbar not displaying in activity

working on a wallpaper app and working on moving to API 21 and removing the ActionBar in favor of Toolbar. That being said, I am trying to use the v7-support library. What happens is basically there is a grey outline of where the toolbar should be, but it never appears.

If I remove the setContentView from the onCreate method, I get an error:
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.CharSequence android.support.v7.widget.Toolbar.getTitle()' on a null object reference
Any ideas on what I can do to correct this?
Screenshot:

You need to add a android.supprt.v7.widget.Toolbar to your layout and then do this in the onCreate method of your ActionBarActivity
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActitionBar(toolbar);
Also, make sure your theme uses Theme.AppCompat.NoActionBar (or Theme.AppCompat.Light.NoActionBar)

FWIW - i just retrofitted some ABS stuff to the newer Toolbar stuff that you are on and had some issues with the Title not showing up in all Frgments, activities.... Some worked some did not. Very frustrating to have varied outcomes. Had to replicate the following code in places where i did not think it should be needed due to inheritance and due to calls to 'super.onCreate()'..
toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(true);
After populated the above code everywhere in those activities/frags where it did NOT show up, the issue resolved.
Really odd that ur title flashes up then disappear.. something is repainting the view!

I found out that I needed to
<include layout="#layout/toolbar_layout"/>
in my activity's layout file since I had my toolbar layout defined in its own xml file.
