How to inflate new copies of an ImageView object on a layout?

Question

What I am trying to do is create N (in this case 9) copies of the ImageView object R.id.tile, place each of them at different coordinates on the layout

Answer 1

Edit:

First create a layout with one ImageView with the properties you like

Example:

create file in res/layout/singleimage.xml

<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
           android:id="@+id/image2"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:src="@drawable/ic_launcher"
           android:contentDescription="Sample"/>

And then inflate the ImageView to get the copies of it like this

View[] tiles = new ImageView[9];
// get reference to LayoutInflater
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

for(int i = 0; i<tiles.length; i++) {
    //Creating copy of imageview by inflating it
    ImageView image = (ImageView) inflater.inflate(R.layout.singleimage, null);
    tiles[i] = image;
    tiles[i].setId(i);
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(-1, 345);
    params.leftMargin = 32*2*3;
    params.topMargin = 34*2*3;
    layout.addView(tiles[i]);
}

You have set id to i value here

tiles[i].setId(i);  

But you are (incorrectly) trying to get it from your other resource (the one you wanted to 'clone'):

layout.addView(tiles[i] = (ImageView) findViewById(R.id.tile)); // INCORRECT

Instead, set the id manually as above, and then:

layout.addView(tiles[i]);

And there is no need to call findViewById()
