Body
I want to pass one or more variables between activities in android. One solution is to use global variables, and it is explained here: <a href="https://stackoverflow.com/questions/1944656/android-global-variable">Android global variable</a> which I repeat here: <hr> You can extend the base android.app.Application class and add member variables like so: <pre><code>public class MyApplication extends Application { private String someVariable; public String getSomeVariable() { return someVariable; } public void setSomeVariable(String someVariable) { this.someVariable = someVariable; } } </code></pre> Then in your activities you can get and set the variable like so: <pre><code>// set ((MyApplication) this.getApplication()).setSomeVariable("foo"); // get String s = ((MyApplication) this.getApplication()).getSomeVariable(); </code></pre> <hr> I want to use this and set a global variable in one of my activities when an item on a ListView is pressed. So I have this code: <pre><code> lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { . . . ((MyApplication) this.getApplication()).setSomeVariable("foo"); } }); </code></pre> However I get an error which says "The method getApplication() is undefined for the type new AdapterView.OnItemClickListener(){}". I would like to know what is the reason I get this error and how to fix it, or a better way of passing a variable from one activity to the other. Thanks, TJ

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
