android.view.View is a class in the Android SDK that represents a basic UI component. It serves as a superclass for many other UI components in the Android framework, such as TextView, Button, and EditText.
Here are some examples of using android.view.View in Java:
Example 1: Creating a Button Widget
Button myButton = new Button(context); myButton.setText("Click me"); myButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // Code to handle button click } });
This example demonstrates how to create a Button widget, set its text, and add a click listener to it. The View.OnClickListener.onClickListener() method is a callback method that is triggered when the button is clicked.
Example 2: Adding a View Programmatically
LinearLayout myLayout = new LinearLayout(context); TextView myText = new TextView(context); myText.setText("Hello, world!"); myLayout.addView(myText);
This example shows how to create a LinearLayout widget programmatically, create a TextView widget, set its text, and add it to the LinearLayout. This can be useful for creating dynamic UIs where the layout components are not known in advance.
