Question

Hi everybody I have been working on the same issue for hours.What I wanted to achieve is to set my fonts to TextView and Its finally done.However I am having trouble with RadioGroupThe problem is that when I run my app and checked RadioButton It seems working.Then I have noticed that the other RadioButton is not working.I wasnt able to set anything to Textview When I click on that What am i doing wrong here

Here what I have so far

@EDIT

@Override
    public void onCheckedChanged(RadioGroup rdg, int arg1) {

        ///this is where I need help.How can i set returning values
        RadioButton Che= (RadioButton) findViewById(R.id.Che);
        RadioButton Ser= (RadioButton) findViewById(R.id.ser);

         if(arg1 ==R.id.Che ){
              cutomfonts=getFirstFont();
              myTextView.setTypeface(cutomfonts);
        }else if(arg1 == R.id.ser){
              cutomfonts=getSecondFont();
              myTextView.setTypeface(cutomfonts);
        }   



}

This is Xml File

<RadioGroup
    android:id="@+id/radioGroup1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="68dp"
    android:layout_marginTop="158dp" >

    <RadioButton
        android:id="@+id/Che"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:checked="true"
        android:text="RadioButton" />

    <RadioButton
        android:id="@+id/ser"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="RadioButton" />

</RadioGroup>

<TextView
    android:id="@+id/my_textview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/radioGroup1"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="23dp"
    android:layout_marginTop="57dp"
    android:text="Small Text"
    android:textAppearance="?android:attr/textAppearanceSmall" />

As per my knowledge your you are not register Che or ser radiobutton, Eclipse not find xml defined Che and ser RadioButton value in java file. So you first register do following things,

Che= (RadioButton) findViewById(R.id.Che);
ser= (RadioButton) findViewById(R.id.ser);

after using above code you can try to run it's work perfect. also i put my own code using if else this is also work for you, Now you can implement onCheckedChanged() override method in following way,

@Override
public void onCheckedChanged(RadioGroup arg0, int arg1) {
    if(arg1 == R.id.Che){
          cutomfonts=getFirstFont();
          myTextView.setTypeface(cutomfonts);
    }else if(arg1 == R.id.ser){
          cutomfonts=getSecondFont();
          myTextView.setTypeface(cutomfonts);
    }   
}

Hope this help you!
