    Remove view from parent on Android:

    View myView = findViewById(R.id.my_view);
ViewGroup parent = (ViewGroup) myView.getParent();
parent.removeView(myView);

    Android remove all child views:

    LinearLayout formLayout = (LinearLayout)findViewById(R.id.formLayout);
formLayout.removeAllViews();

    Add view to parent on Android:

    Button myButton = new Button(getApplicationContext());
myButton.setLayoutParameters(new LinearLayout.LayoutParams(
                                     LinearLayout.LayoutParams.FILL_PARENT,
                                     LinearLayout.LayoutParams.FILL_PARENT));

myLayout.addView(myButton);

    you can use:

    LinearLayout.LayoutParams.FILL_PARENT

    or

    LinearLayout.LayoutParams.WRAP_CONTENT
