He loves to blog about what he learns and what he’s up to. For the past six years he’s been working as a web-developer working in the JavaScript ecosystem, and developing web-apps in ReactJS, NodeJS, GraphQL. Nabendu has been working in the software industry for the past 15 years, starting as a C++ developer, then moving on to databases. We've also learned about the built-in toast messages for Android.Īdditionally, we tested the app through Jest, and we learned we also can test the app with the no-code testing platform Waldo. First, we built custom toast messages, which work on both Android and iOS platforms. In this post, we've learned about creating toast messages in React Native. So, create a free Waldo account here to test its features. After that, the test cases will be generated automatically, and our testing will be done automatically. We can then do user iteration like clicking on the button. With this platform, we just need to upload the APK or IPA file. To do this, we can use the no-code testing platform Waldo instead of writing all test cases manually. However, adding the Toast.js component to the testing would require us to write a very complicated test case. To pass the Android dropdown menu to Java, you have to define a Spinner object. However, if you still get a Syntax error, you can always hover your mouse over it and then press Alt-Enter to import the relevant class for your code. Then, clear the interval by using clearInterval.įinally, in the onNewToast(), check if the duration is passed and set it to the timeOut variable. import It’s best that these classes are imported beforehand to avoid any syntax errors later on. In the closeToast(), set the message to null and, again, set the timeOut variable to 4,000 milliseconds. If it becomes 0, which means it ran four times, we're calling the closeToast function. We've also made it equal to the timeOutRef varible declared earlier, each time reducing 1,000 milliseconds from the timeOut state variable. Here, we'll use the setInterval function to run every 1,000 milliseconds. It's required to create a ref because we'll use it at different places in our code.

We've also created a ref with the name timeOutRef. Here, we'll use a new state variable called timeOut, which has an initial value of 4,000 milliseconds.

So, let's add this feature in the Toast.js file. Package import import import import import import import android.os.Bundle import import import import import .Our toast message will be shown continuously, but a toast message needs to disappear after some time.
