How to get ID of imagebutton when it is clicked

public void onClick(View v) {

    int id = v.getId();
    switch(id) {
        case R.id.a :
        String textans = ans.getText().toString();
        ans.setText(textans +id);
    }
}

I am creating an android application in which i have 5 ImageButtons and a TextView.

ImageButtons are having alphabet images i.e A, B, C, D, E and their ID's in XML are a, b, c, d, e as follows

<ImageButton
        android:id="@+id/a"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_marginBottom="170dp"
        android:layout_marginLeft="18dp"
        android:src="@drawable/a" />

    <ImageButton
        android:id="@+id/b"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/imageButton5"
        android:layout_toRightOf="@+id/imageButton5"
        android:src="@drawable/b" />

    <ImageButton
        android:id="@+id/c"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/imageButton2"
        android:layout_toRightOf="@+id/imageButton2"
        android:src="@drawable/c" />

    <ImageButton
        android:id="@+id/d"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/imageButton3"
        android:layout_toRightOf="@+id/imageButton3"
        android:src="@drawable/d" />

    <ImageButton
        android:id="@+id/e"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/a"
        android:layout_toRightOf="@+id/a"
        android:src="@drawable/e" />

What I want is when I click an ImageButton the respective letter must be set in TextView. For this purpose I have used a switch in onClick method and tended to get the ID of the button and set it in TextView but id is something in int.

My question is this "How can I get the name of the ID of button clicked". For example when Iclick button having image A, the id of ImageButton is "a", so it must be stored in a variable and then it is set to TextView.

Hopefully my question is much clear.

If you want to set the ID of the clicked button to your TextView you could use something like this

String resourceName = getResources().getResourceEntryName(int resId);

Use in your solution

public void onClick(View v) {

    int id = v.getId();
    switch(id) {
        case R.id.a:
            String resourceName = getResources().getResourceEntryName(id);
            textView.setText(resourceName);
            break;
    }
}
