Dynamic Xml, Changing Text

Hello I want to do this: I am pulling data from a server and I need when for example pull out the number 0 the textview to ber red color, on any other case to be green color. I do

Solution 1:

You need to to first instantiate your text view like

TextView tv = (TextView)findViewById(R.id.idOfTextViewInXML);

Now you can perform change this text view as you please . For example

if(var==0)
    tv.setText("VALUE IS ZERO");
else
    tv.setBackgroundResource(R.drawable.icon);

This is the way you need to change the features of views dynamically . You can't really change the XML itself dynamically .

All this must be performed in the Java class .

Solution 2:

Once u have data from sever in form of xml , parser the xml and process it (to check for your condition ).

Solution 3:

When you parse your xml in your code, just add a if statement.

if(number == 0){


 else{
 //do something
  }
