Hi, I am making a simple application to experience material design. Unfortunately, after an incredible tutorial here and try the samples here (These are incredible sources for FYI in material design). I try my best to make the application toolbar work as it should. For example, the back button next to the title does not appear when a crash occurs. BUT I can just click on this area where it should be, and she answered.
So, there is a button, but it does not appear, and I cannot understand why. In addition, when the toolbar crashes, the toolbar does not change its color to the primary color that I set. contentScrim does not seem to respond to collapse mode, but I will post one more question for this.
Here is what it now looks like:
Now that the collapse, the name is noticeably far right. There is a button, I can click on it, it will return to the working screen of my application, but the "Back" icon does not exist.
Here is the layout file for the activity:
