Detecting the check status of a checkbox in react native: a complete guide

I'm currently working on a scenario where I need to implement logic for checking or unchecking a checkbox in React Native. If the checkbox is checked, I want to print one string, and if it's unchecked, I want to print something else. How can I achieve this in React Native?

Below is my code snippet:

checked={this.state.checked}
                onPress={() => {
                  this.actiondone();
                }}

actiondone(){
   //Need to determine if checkbox is checked or not and perform actions accordingly
}

android ios typescript react-native

Answer №1

To achieve this functionality, you can manipulate the state of your checkbox based on its current status. If the checkbox is checked (i.e., this.state.checked = true) and you want it to be unchecked when pressed, then you need to set the state to unchecked, and vice versa. Simply invert the current state of the checkbox and update the state accordingly.

In essence, you will reverse the current state of the checkbox and then assign the desired state asynchronously.

Here is an example implementation:

<CheckBox
  checked={this.state.checked}
  onPress={() => this.performAction()}
/>

performAction() {
    if (this.state.checked) {
        // Code for handling checkbox being unchecked
    } else {
        // Code for handling checkbox being checked
    }

    // Update the checkbox state to the desired value
    this.setState({checked: !this.state.checked})
}
