Answer 1

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
