I want to pass a reference of the current activity to a method of a class not extending Activity. I need to use this reference to the active activity so that I can use getWindow().addFlags(LayoutParams.FLAG_KEEP_SCREEN_ON);
I pass both the current context and activity to the class object using these setter methods in the class:
public class VersionCheck {
public Context context;
public Activity activity;
//---------------------------------------------------------------------------------------------------------
//set the current context
//---------------------------------------------------------------------------------------------------------
public void setContext(Context context) {
this.context = context;
}
//---------------------------------------------------------------------------------------------------------
//set the current activity
//---------------------------------------------------------------------------------------------------------
public void setActivity(Activity activity) {
this.activity = activity;
}
The reference to the activity is used in an AsyncTask in the class (extract below):
//---------------------------------------------------------------------------------------------------------
//asynchronous task to check if there is a newer version of the app available
//---------------------------------------------------------------------------------------------------------
private class UpdateCheckTask extends AsyncTask<String, Void, String> {
HttpClient httpclient;
HttpPost httppost;
HttpResponse response;
InputStream inputStream;
byte[] data;
StringBuffer buffer;
protected void onPreExecute ()
{
VersionCheck vc = new VersionCheck();
//do not lock screen or drop connection to server on login
activity.getWindow().addFlags(LayoutParams.FLAG_KEEP_SCREEN_ON);
//initiate progress dialogue to block user input during initial data retrieval
ProcessingDialog = ProgressDialog.show(context, "Please Wait", "Checking for Updates", true,false);
}
@Override
protected String doInBackground(String... currentVersion)
{
How do I get a reference to the Activity so that I can pass it to the setActivity(Activity) method? I use myActivity.this as reference for the context. Is it the same for Activity?
