Question

My button is:

  <Button
      android:text=""
      android:id="@+id/b1"
      android:gravity="center_horizontal"
      android:layout_width="100dp"
      android:layout_height="100dp"
      android:background="@drawable/the_border"
      android:textSize="75sp"/>

And I have many of them (b0, b1, b2)…

My java:

    for(int index = 0; index < 9; index++)
    {
        places[index] = (Button) findViewById(R.id.b + index);
        places[index].setOnClickListener(this);
    }

How could I do this? findViewById(R.id.b + index) needs to be changed. Is it possible? Thanks

Use the tag property to give them sequential tags of 0, 1, 2, etc., then findViewWithTag() in a loop to build an array. Note that tag is a string, it’s not numeric.
