EditText requestFocus()?

I got a problem with requestFocus.

First, this is my source code:

<EditText
    android:id="@+id/etGLNum2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_centerVertical="true"
    android:layout_toLeftOf="@+id/btGLCalculate"
    android:ems="10"
    android:hint="@string/gl_num2_hint"
    android:inputType="number" />

<EditText
    android:id="@+id/etGLNum1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/etGLNum2"
    android:layout_alignParentLeft="true"
    android:layout_toLeftOf="@+id/btGLCalculate"
    android:ems="10"
    android:hint="@string/gl_num1_hint"
    android:inputType="number">

    <requestFocus />
</EditText>

<TextView
    android:id="@+id/tvGLResult"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_below="@+id/etGLNum2"
    android:gravity="center"
    android:text="@string/result"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<Button
    android:id="@+id/btGLCalculate"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/tvGLResult"
    android:layout_alignParentRight="true"
    android:layout_alignTop="@+id/etGLNum1"
    android:text="@string/calculate" />

As you see, focus have to go to etGLNum1, but it always goes to etGLNum2.

I already tried adding etGLNum1.requestFocus(); from my java file but it didn't worked.

What should i do?

Thanks :)

With what i have experienced is, Android have a a default behavior of giving focus to the first focusable element found in the current surface(if we have not set any default element to focusable).
You can use etGLNum1.setFocusable(true) (before setContentView() call) then etGLNum1.requestFocus() (after setContentView() call) from your onCreate()..
It should work..

Add requestFocus in your Edittext. 

<EditText
    android:id="@+id/etGLNum2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_centerVertical="true"
    android:layout_toLeftOf="@+id/btGLCalculate"
    android:ems="10"
    android:hint="@string/gl_num2_hint"
    android:inputType="number">
    <requestFocus />
</EditText>

In your onCreate() write:

EditText etGLNum1 = (EditText)findViewById(R.id.etGLNum1);
etGLNum1.requestFocus();
etGLNum1.setOnFocusChangeListener(new OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) 
    {
        //enter code here
    }
});

 try this :-
 etGLNum2.setOnFocusChangeListener(new OnFocusChangeListener() {      
        @Override
        public void onFocusChange(View rv, boolean hasFocus) {

                       etGLNum2.clearFocus();
                   etGLNum1.requestFocus();



         }
      }
    });
