java - Enable a currently disabled Spinner in Android -


I was fooling around with Android and my Java knowledge was best (for example, I'm upset with this fact That it allows inline squares !?).

My question is as follows:

I have a layout where there are three dropdown menus, I initialize all three of them in the form ().

The first takes its value from a string-array; Second, however, depends on the first choice and the third depends on the choice of the other in turn!

I have some string-arrays for the second spinner, but I think that what would be the right way to implement the list of successively capable spinners, I just wanted to hack into it and work it I am trying, but I do not want to run the risk of being faulty and unstable.

For example, my case is like I have

in my resources I have an arrays.xml like:

In the onCreate method I started three: 

  @Override Public Zero OnCreate (bundled savedInstanceState) {super.onCreate (savedInstanceState); SetContentView (R.layout.main); Spinner spinner 1 = (spinner) Find VVBIID (RID planetpinner); Spinner Spinner 2 = (Spinner) Find VVBiID (RID. Moonspinner); Spinner Spinner 3 = (Spinner) Find VVBIID (RID Crater Spinner); Spinner2.setEnabled (false); Spinner3.setEnabled (false); ArrayAdapter adapter1 = ArrayAdapter.createFromResource (This, R.array.planets, android.R.layout.simple_spinary_item); Adapter1.setDropDownViewResource (android.R.layout.simple_spinner_dropdown_item); Spinner1.setAdapter (adapter1); Spinner1.setOnItemSelectedListener (New MyOnPlanetSelectedListener ()); }

is my listener class 

  public class MyOnPlanetSelectedListener applies OnItemSelectedListener {Public Zero onItemSelected (AdapterView & LT;? & Gt; Parents, View View , Int status, long id) {Toast.makeText (parent.getContext ()), "Planet" + parent.getItemAtPosition (POS) .toString (), Toast.LENGTH_LONG) .show (); } Nothing at public zero (adapterviewer parent) {// do nothing}}

So there it is. My question is, how and how to implement the listeners for continuous spinners so that they can be enabled after the first selection. My first estimate is: 

  Public class MyOnPlanetSelectedListener applies OnItemSelectedListener {Public Zero onItemSelected (AdapterView << Parents, View View, Status Int, Long ID?) {Toast.makeText (Parent.getContext ()), "Planets" + Parents. Gate IT status (pause) .toString (), Toast. LNNGH_LOG). Show (); Spinner2.setEnabled (true); } Nothing at public zero (adapterviewer parent) {// do nothing}}

But obviously this is wrong since spinner2 is not explained here.

Then, on the basis of spinners continuously, a string array for your adapter should be selected. Before selecting spinners

Thank you very much for your help.

for onprinted Code> onItemSelected >>> This is simple by event logic.

Create spinner 1, 2 and 3 members of the class (activity) 

  private spinner spinner 1;

Then compare the view against the ultimate 

  (see == this.spinner1) {// Spinner 1 // came out of the event, create a new adapter, repeat the new adapter to the spinner 2} and if (see == this.spinner2) {// event came from spinner 2}

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
