half or quarter black screen in android - android

I have an android activity that when I launch sometimes (about 1 in 4 times) it only draws quarter or half the screen before showing it. When I change the orientation or press a button the screen draws properly.
I'm just using TextViews, Buttons, Fonts - no drawing or anything like that.
All of my code for initialising is in the onCreate(). In this method I'm loading a text file, of about 40 lines long, and also getting a shared preference. Could this cause a delay so that it can't draw the intent?
Thanks in advance if anyone has seen anything similar.
EDIT - I tried commenting out the loading of the word list, but it didn't fix the problem.
EDIT 2 - I didn't manage to resolve the problem, but managed to improve it by adding a timer right at the end of the onCreate. I set a low refresh rate and in the tick changed the text of one of the controls. This then seemed to redraw the screen and get rid of the black portions of the screen.
Here is the activity

Then my code that says or go data :
public class DetailEtab extends Activity {
private TextView tv;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.etabdetail);
tv = (TextView) findViewById(R.id.tvl);
tv.setText(search_ville.etabSELECT.getLibelle());
tv = (TextView) findViewById(R.id.tvcp);
tv.setText(search_ville.etabSELECT.getCp());
tv = (TextView) findViewById(R.id.tvv);
tv.setText(search_ville.etabSELECT.getVille());
tv = (TextView) findViewById(R.id.tvp);
tv.setText(search_ville.etabSELECT.getPresentation());
Button btnSa = (Button) findViewById(R.id.btnMa);
btnSa.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(DetailEtab.this, MaterielAssocie.class);
startActivity(intent);
Log.i("ETAB", "servcies associes");
Toast toast = Toast.makeText(getApplicationContext(), "services associes", Toast.LENGTH_SHORT);
toast.show();
}
});
}
}
If anyone can tell me why it does that thanks

You have problems with your layouts. I recommend you to wrap every line into separate LinearLayout and then use LinearLayout to wrap all new LinearLayouts. Also due to long text it's better to wrap parent LinearLayout into Scroll.
NOTE: This is just example that was written inside text box that simply shows main idea and may contain mistakes
Something like this:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/tvd"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Détail de l'établissement"
android:textSize="20dp"
android:textStyle="bold"/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/textView3"

You are assigning tv to multiple different TextViews and then you are assigning multiple values to the last TextView you assign it to.

How to position an ImageView in the same place in different screen sizes?

I been working on a simple android app that calculates a person's Body Mass Index, I have all the features working but positioning the arrow in the right place in the color bar corresponding to the user's screen size is what Im stuck on. I have it working by setting the X and Y values of the arrow ImageView but obviously the place of the arrow changes when i test my application in different screen sizes even though im coverting a dp value to pixels. How can I position the arrow ImageView so that it stays the same in different screen sizes?

Add Linearlayout as subparent of childview,use its orientation and gravity attribute you can easily get the design in more optimize way and suitable for everyscreen size.
here i have used RelativeLayout as Parent and LinearLayout as sub-parent of childview.

The parent RelativeLayout has:
android:layout_width="fill_parent"
And, indeed, in your image, it does will the parent's width. At the least, you will need to change that to:
android:layout_width="wrap_content"
It would also be good practice to define the relative layout fully:
<TextView
android:id="#+id/tvname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:fontFamily="georgia"
android:paddingBottom="29dip"
android:text="#string/strname"
android:textColor="#000000"
android:textSize="14sp"
android:textStyle="bold"
android:typeface="serif" />
<TextView
android:id="#+id/tvdate"
android:layout_marginTop="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_marginRight="10dp"
android:text="#string/strtime"
android:textColor="#FFFFFF"
android:textSize="9sp"
/>
<TextView
android:id="#+id/tvmessage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="28dp"
android:layout_marginLeft="5dp"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_below="#id/tvname"
android:text="#string/strstatus"
android:textColor="#B5ACAF"
android:textSize="15dip"
/>
I know is bit late but may help others with the problem.
bg.setBackgroundResource(R.drawable.bubble_green);
Isn't set in the viewHolder so isn't resizing.
Declare the bg layout in the viewHolder and call it:
holder.bg.setBackgroundResource(R.drawable.bubble_green);

detecting a component click in a custom listview item

I Have a ListView. In my listview I create a custom items on every rows. this custom item as some textviews and two buttons. The problem I have now is I want to detect when the user clicks on the buttons in the listview items.
But My code is not working.
Please don't mind the numerouse text views that are to be hidden from the user only one is to be seen by the user and the two buttons are visible.
Each time I click the button nothing happens, no response

My activity code is also pasted below. The OnItemClickListener of the ListView component, is what is below :
private AdapterView.OnItemClickListener itemclickListener = new AdapterView.OnItemClickListener(){
String drugID = null,drugName = null, drugPrecription = null, drugManufacturedate = null, drugExpiratorydate = null,drugCode = null, nafdacNo=null,drugageRange = null;
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
drugID = ((TextView)view.findViewById(R.id.drugID)).getText().toString();
drugName = ((TextView)view.findViewById(R.id.itemname)).getText().toString();
drugPrecription =((TextView)view.findViewById(R.id.itemprescrip)).getText().toString();
drugManufacturedate = ((TextView)view.findViewById(R.id.itemanufac)).getText().toString();
drugExpiratorydate = ((TextView)view.findViewById(R.id.itemexdate)).getText().toString();
drugCode = ((TextView)view.findViewById(R.id.itemdcode)).getText().toString();
nafdacNo = ((TextView)view.findViewById(R.id.textViewName)).getText().toString();
drugageRange = ((TextView)view.findViewById(R.id.agerange)).getText().toString();
orderButton = (ImageButton)parent.getChildAt(9);//view.findViewById(R.id.ordernow);
detailsButton = (ImageButton)parent.getChildAt(0);//view.findViewById(R.id.details);
Object o = orderButton.getClass();
Toast.makeText(context, o.toString(), Toast.LENGTH_SHORT).show();
//Now we are going check for the button that would clicked
//int elementID = view.getId();
//this.detectItemClicked(elementID);
}
