Here is an example of uploading Json Data to a MySQL database on a website/Server from a Android phone. This is great to upload user data from the phone to a website. The bad thing is that you have to use a different Thread instead of the main UI thread. It fairly simple to multithread even though some examples makes it pretty complicated. Check out my attempted to explain an example of using the Android Thread class.
Here is an example of how to select a game object by touch using Unity 3d’s Physics Raycast. The first part is to find the game object that the user is touching with their finger. This is done by a raycast. If that is all you want to do then you can skip the inner ‘if statement.’ The next step is to get the finger’s position in pixels and then convert it to game world coordinates.
If you want to add text to a picture that you took from your Android camera app that you built then you came to the right spot. This is an addition to my post Camera Application in Android Example. So if you do not have a working camera app yet then I would recommend using the code posted there. It is only small addition and you should not have an issue adding the code to your existing code. Here is an example of a picture with text printed on the picture:
Here is a full example of building a camera app in Android that was taken from the Google tutorial.This is the complete tested camera code all in one place with no errors. There was a few errors i got from copying and pasting the code from the Google tutorial but they are fixed in this example. I also added code to display the last image taken so the user can open the picture in a image viewer. I removed excess code without testing so comment if you are having issues so I can make corrections.
Here is how to center 2 buttons inside a layout. These do not have to be buttons but can be any type of view. The idea behind it is to create a layout and add two horizontal Linear Layout inside and assign the same weight to both. When the buttons are inside then center the buttons inside the layout. Since each layout is set to ‘match_parent’ then it will scale to any screen size.
We took a trip to look for an abandon Engine in a field today but was surprise to also find the abandon Roosevelt railroad M line. This was a 7 mile rail line that President Roosevelt took as he went down to Warm Springs Georgia. The President rode the line around 50 times and his funeral train rode this line. There use to be a Museum at this location but also has become abandon. The engine in the photo was built in 1892. There is another image of a cart that they was planning on taking tours on. I found some 2009 Youtube videos of maintenance workers using it and traveling down the rail line.
Here is a an example of repeating a cell/layout inside of a layout. The hard part I found was trying to get the text from the Edit Text field since using the id will not work. You can use the position of the cell but since the list can get rearranged due to the soft keyboard popping up. Setting a tag to the edit text field will work better.
I created two different ways to gather the input: using a holder inside the adapter and using a TextWatcher. A TextWatcher will grab the input in real time unlike a holder which will update when the focus changes.
