Layout inflater inflates FrameLayout instead of my custom view

Question

My aim is to inflate my custom view from layout

custom view layout:

<net.rhyboo.com.game_test.Piece xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:scaleType="fitXY"
    android:id="@+id/piece_view">

</net.rhyboo.com.game_test.Piece>

class associated with this layout:

package net.rhyboo.com.game_test;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;

public class Piece extends ImageView {

    public Piece(Context context, AttributeSet atrs) {
        super(context,atrs);
    }

    public Piece(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
}

But when I try to inflate with the code:

//get layout inflater
LayoutInflater li=(LayoutInflater)activity.getSystemService(Service.LAYOUT_INFLATER_SERVICE);
//parent view for my custom view
FrameLayout gf =(FrameLayout)fragment.getView().findViewById(R.id.game_field);
//inflation attempt
Piece p=(Piece) li.inflate(R.layout.piece_view,gf);

I got the error

java.lang.ClassCastException: android.widget.FrameLayout cannot be cast to net.rhyboo.com.game_test.Piece

Why layout inflater generates FrameLayout while type of my view is Piece which is subclass of the ImageView?

Answer 1

Instead of:

//get layout inflater
LayoutInflater li=(LayoutInflater)activity.getSystemService(Service.LAYOUT_INFLATER_SERVICE);
//parent view for my custom view
FrameLayout gf =(FrameLayout)fragment.getView().findViewById(R.id.game_field);
//inflation attempt
Piece p=(Piece) li.inflate(R.layout.piece_view,gf);

try

//get layout inflater
LayoutInflater li =(LayoutInflater)activity.getSystemService(Service.LAYOUT_INFLATER_SERVICE);
//parent view for my custom view
FrameLayout gf = (FrameLayout)fragment.getView().findViewById(R.id.item);
//inflation attempt
Piece p = li.inflate(R.layout.piece_view, null);
gf.addView(p);

EDIT: To see Image in original size add this parameters to ImageView :

android:scaleType="center"

I think you should try it in these two ways:

1. If you want your custom view to be added to the Frame Layout then use

View view = inflater.inflate(R.layout.your_custom_layout, mFrameLayout, true);

2. If you do not want your custom view to be added to the Frame Layout then use

View view = inflater.inflate(R.layout.your_custom_layout, parent, false);

Possible correction in your code:

View view =li.inflate(R.layout.piece_view,gf);

Or View view =inflater.inflate(R.layout.piece_view,gf);

Finally return view;

According to the error it seems you are wrongly casting Frame Layout to your custom layout here

//inflation attempt Piece p=(Piece) li.inflate(R.layout.piece_view,gf);
