<item android:state_selected="true" android:color="#000000"/>
<item android:color="#d3d3d3"></item>
</selector>

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.

SqlLiteExample.java :
public class SqlLiteExample extends Activity implements OnClickListener, OnCheckedChangeListener {
Button sqlUpdate, sqlView;
EditText etName,etAge,etContact;
RadioGroup rdgrp;
RadioButton selectedRadioButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sqlliteexample);
sqlUpdate = (Button) findViewById(R.id.savebutton);
etName = (EditText) findViewById(R.id.editName);
etAge = (EditText) findViewById(R.id.editAge);
etContact = (EditText) findViewById(R.id.editContact);
rdgrp.setOnCheckedChangeListener(this);
sqlView = (Button) findViewById(R.id.viewbutton);
sqlView.setOnClickListener(this);
sqlUpdate.setOnClickListener(this);
}
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
switch(arg0.getId()){
case R.id.savebutton:
boolean didWork = true;
try{
String name = etName.getText().toString();
String age = etAge.getText().toString();
String contact = etContact.getText().toString();
MyDB entry = new MyDB(SqlLiteExample.this);
entry.open();
entry.createEntry(name,age,contact);
entry.close();
}catch(Exception e){
didWork = false;
String error = e.toString();
Dialog d = new Dialog(this);
d.setTitle("Error");
TextView tv = new TextView(this);
tv.setText(error);
d.setContentView(tv);
d.show();
}finally{
if(didWork){
Dialog d = new Dialog(this);
d.setTitle("Updated");
TextView tv = new TextView(this);
tv.setText("Success");
d.setContentView(tv);
d.show();
}
}
break;
case R.id.viewbutton:
Intent i = new Intent("com.bysakiralam.mydatabase.DISPLAYRECORDS");
startActivity(i);
break;
}
}
#Override
public void onCheckedChanged(RadioGroup arg0, int arg1) {
// TODO Auto-generated method stub
switch(arg1){
case R.id.malebutton:
break;
case R.id.femalebutton:
break;
}
} }

There is no need to override onCheckedChanged() use following in your on savebutton click
rdgrp=(RadioGroup)findViewById(R.id.RadioGroup01);
String radiovalue= (RadioButton)this.findViewById(rdgrp.getCheckedRadioButtonId())).getText().toString();
and now use radiovalue to store in database
Edit: forget (
rdgrp=(RadioGroup)findViewById(R.id.RadioGroup01);
String radiovalue= ((RadioButton)this.findViewById(rdgrp.getCheckedRadioButtonId())).getText().toString();

try this
myRadioGrp=(RadioGroup)findViewById(R.id.RadioGroup01);
String radiovalue= ((RadioButton)this.findViewById(myRadioGrp.getCheckedRadioButtonId())).getText().toString();

TableLayout inside ListView

There is a page in my android application which has a slide out menu and some data that needs to be displayed in the main screen. The slide out menu has the required menu options.
the main page is in ListView format. I want a TableLayout format layout inside this ListView.
The problem is when i change the layout to TableLayout, it messes up with my java activity file.
I want to display data extracted from an external source on the main screen of this page in table format.
The XML and Java Activity files are enclosed.
Thanks in advance.

I Used MultiColumn ListView Instead.

half or quarter black screen in 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
