Download Code<\/a> ?<\/a><\/p>\n Step 1:<\/strong><\/span>\u00a0Create a new project and name it DynamicRelativeLayout.<\/p>\n Step 2:<\/strong><\/span>\u00a0Open res -> layout ->activity_main.xml (or) main.xml and add following code:<\/p>\n In this step we open xml file and then add RelativeLayout as main layout in which we add views programmatically means in java class.<\/p>\n Step 3:<\/strong><\/span>\u00a0Open\u00a0 \u00a0src -> package -> MainActivity.java<\/p>\n In this step Firstly we get the reference of RelativeLayout. After that we add the code to create ImageView<\/a> and a Button<\/a> one after another. We also set the different properties of ImageView and Button. Finally we perform onClick event listener on Button so whenever a user click on Button a message \u201c Button Clicked\u201d is displayed on screen by using a Toast.<\/p>\n Output:<\/strong><\/p>\n Now run the App and you will see one image and a Button which is created dynamically i.e. programmatically in JAVA.<\/p>\n Below is the example of Dynamic RelativeLayout aka programmatically. In this example we created dynamic view\u2019s (ImageView and Button) programmatically in Java class. For creating views programmatically firstly we define the Relative Layout in our xml file and then add the code in java class to create ImageView and a Button one after another.
