ProjectChooserHelper

public class ProjectChooserHelper extends Object
Helper class to deal with displaying a project choosing dialog that lists only the projects with the Android nature.

Fields Summary
private final org.eclipse.swt.widgets.Shell
mParentShell
private org.eclipse.jdt.core.IJavaProject[]
mAndroidProjects
List of current android projects. Since the dialog is modal, we'll just get the list once on-demand.
Constructors Summary
public ProjectChooserHelper(org.eclipse.swt.widgets.Shell parentShell)

        mParentShell = parentShell;
Methods Summary
public org.eclipse.jdt.core.IJavaProjectchooseJavaProject(java.lang.String projectName)
Displays a project chooser dialog which lists all available projects with the Android nature.

The list of project is built from Android flagged projects currently opened in the workspace.

param
projectName If non null and not empty, represents the name of an Android project that will be selected by default.
return
the project chosen by the user in the dialog, or null if the dialog was canceled.

        ILabelProvider labelProvider = new JavaElementLabelProvider(
                JavaElementLabelProvider.SHOW_DEFAULT);
        ElementListSelectionDialog dialog = new ElementListSelectionDialog(
                mParentShell, labelProvider);
        dialog.setTitle("Project Selection");
        dialog.setMessage("Select a project to constrain your search.");

        IWorkspaceRoot workspaceRoot = ResourcesPlugin.getWorkspace().getRoot();
        IJavaModel javaModel = JavaCore.create(workspaceRoot);

        // set the elements in the dialog. These are opened android projects.
        dialog.setElements(getAndroidProjects(javaModel));

        // look for the project matching the given project name
        IJavaProject javaProject = null;
        if (projectName != null && projectName.length() > 0) {
            javaProject = javaModel.getJavaProject(projectName);
        }

        // if we found it, we set the initial selection in the dialog to this one.
        if (javaProject != null) {
            dialog.setInitialSelections(new Object[] { javaProject });
        }

        // open the dialog and return the object selected if OK was clicked, or null otherwise
        if (dialog.open() == Window.OK) {
            return (IJavaProject) dialog.getFirstResult();
        }
        return null;
public org.eclipse.core.resources.IProjectgetAndroidProject(java.lang.String projectName)
Helper method to get the Android project with the given name

param
projectName the name of the project to find
return
the {@link IProject} for the Android project. null if not found.

        IProject iproject = null;
        IJavaProject[] javaProjects = getAndroidProjects(null);
        if (javaProjects != null) {
            for (IJavaProject javaProject : javaProjects) {
                if (javaProject.getElementName().equals(projectName)) {
                    iproject = javaProject.getProject();
                    break;
                }
            }
        }    
        return iproject;
public org.eclipse.jdt.core.IJavaProject[]getAndroidProjects(org.eclipse.jdt.core.IJavaModel javaModel)
Returns the list of Android projects.

Because this list can be time consuming, this class caches the list of project. It is recommended to call this method instead of {@link BaseProjectHelper#getAndroidProjects()}.

param
javaModel the java model. Can be null.

        if (mAndroidProjects == null) {
            if (javaModel == null) {
                mAndroidProjects = BaseProjectHelper.getAndroidProjects();
            } else {
                mAndroidProjects = BaseProjectHelper.getAndroidProjects(javaModel);
            }
        }
        
        return mAndroidProjects;
