Now here is the cool part. The important parts of using fragments are creating our master and detail fragments and using fragment transactions to insert them into their respective containers. We can use fragment callbacks to pass the item ID up to the activity. We can then add a public method on DetailFragment for the activity to pass the ID to the detail fragment. This is a good initial guess at tablet size.

Again, we still have two containers for master and detail fragments. We also need the Toolbar. This is really up to you. You may decide to just wrap the width of the master container and give all the remaining width to the detail.
Your choice. Now we need to head back to our Activity and make sure it can handle this new layout. We need to make just a few changes:.

All we need to do is null check drawerLayout before setting up drawer view and menu icon before we try to close the drawer. At this point, we are almost wrapped up.
Using Fragments to Simplify the Android Navigation Drawer
Checking our results on several phones and tablets indicates things are working as expected. Navigation drawer looks terrible on devices API 19 and newer. Looks fine on devices older than API However on these newer devices, if our drawer content is too near the top it will get partially obscured by the status bar. Fixing this problem is quite easy though. This works because smallest width qualifiers are checked before API version qualifiers. Navigation drawer finally looks good on phones that are API 19 and newer. Tags: andriod studio navigation drawer android go programming language navigation drawer.

Android development continues to get more productive as we move forward and as some great software engineers step up to…. In this post, I'll cover how to make an Android To Do application that keeps track of your tasks.
Hello, thanks for your time writing this down. Would it be possible have this example as a download file somewhere, or do you have it on github? It would make it easier to check everything out as it should be. Hope that helps! Note that because I have two different fragments, I had to implement the interfaces for both FragmentOne. This also prevents any possible jankiness that you could see when launching a new activity.
One last thing to note is that if you switch to a different fragment and then rotate the device or cause another recreation of the activity, the code above will cause the first fragment to be reloaded. One easy way to deal with that is to wrap the fragment block in the onCreate method in a check to see if the savedInstanceState is not null like this:.
One actual last thing is that there are definitely optimizations you could make on the code and event handling here but this is a good start.
