I tried to inflate this [constrains layout](https://i.stack.imgur.com/C891I.png) into another constrains layout.

but when I run it i got only get the [pink card](https://i.stack.imgur.com/osgOi.png) the four ImageView doesn't appear inside the card .

here is the main XML file which I need to inflate another layout inside it.

```

here is java class related to the previous main XML

```
public class StepThreeActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_step_three);

    initialization();
    characterInitialization();

    LayoutInflater inflater =
            (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
      inflater.inflate(R.layout.card1,
              constraintLayout, true);  
}

```

here is card1.xml code
