Android LayoutInflater - Dynamically Add and Remove Views using Java code

How to manipulate Android screen using predefined XML layouts? This can be done with the help of LayoutInflater. This class is used to instantiate layout XML file into its corresponding View objects. It is never to be used directly -- use getLayoutInflater() or getSystemService(String) to retrieve a standard LayoutInflater instance that is already hooked up to the current context and correctly configured for the device you are running on. For example:

LayoutInflater inflater = (LayoutInflater)context.getSystemService (Context.LAYOUT_INFLATER_SERVICE);

Click here if you are interested in generating layout views such as Button, TextView, EditText, RadioButton, CheckBox, ToggleButton, etc. programmatically in Java code.

  4. Thanks for this! I've been trying to understand WHY one uses LayoutInflater and this makes it very clear.

  5. Hi Nice example... thanks a lot

    But while remove we need to check this condition in java code. Otherwise it will throw NullPointerException.

    View myView = findViewById(;
    if(myView != null)
    System.out.println("---------view is not null");
    ViewGroup parent = (ViewGroup) myView.getParent();

    1. yes we need to check for the null condition else throws exeption....nice example

    for(int i = 0; i < appList.size(); i++) {
    TextView view=new TextView(getBaseContext());
    Integer color = Integer.parseInt("424242", 16)+0xFF000000;
