Android Check Box
A checkbox in Android development is a user interface element that allows users to select one or more items from a list of options. When a checkbox is selected, a checkmark appears in the box, indicating that the item has been chosen.
Check Box Uses
- Allow users to select one or more options from a list.
- Provide users with an easy way to make a yes or no decision.
- Enable users to choose from a limited number of options.
- Enable or disable certain features in an app based on user selection.
Example: Here is an example of how to create a checkbox in an Android app:
1. Add the following code to your app's XML layout file:
<CheckBox
android:id="@+id/my_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Select Me" />
2. In your app's Java code, add the following code to handle checkbox clicks:
CheckBox checkBox = findViewById(R.id.my_checkbox);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
// Do something when checkbox is checked
} else {
// Do something when checkbox is unchecked
}
}
});
This code sets up a listener that detects when the checkbox is checked or unchecked and executes code accordingly.
