I have a problem to start/create Activity in landscape mode. My Activity need to start in landscape mode and be used in landscape mode by users. So far, I used setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) to force screen orientation of my Activity to landscape mode in onCreate() method.
In addition to this screen mode requirement, my application need to start another background thread in onResume() method, and this thread takes some seconds in order to finish an initialization process, and it is not desirable to to stop/restart this thread's service during the initialization process.
However setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) forces my Activity restart in a very little while (means onCreate->onResume->onPause->onStop are executed twice at the first place). As a result, my background thread be stopped/restarted during the initialization process, and this makes me a mess at this moment.
My activity contains an editable text view and I would like to automatically show the soft keyboard when the activity start. Anyone knows how to do it?
I tried this:

I am using android vnc viewer on my G1. But for some reason, that application always in landscape mode despite my G1 is in portrait mode. Since android vnc viewer is open source, I would like know how is it possible hard code an activity to be 'landscape'. I would like to change it to respect the phone orientation.

View 5 Replies View RelatedI have an Android application with a main activity that is the tabhost. I'm adding multiple tabs to the tabhost with an intent to several activities.
My problem is that these activities are not created (onCreate is not called) until I click on the tab. This is a problem because I need to register broadcastreceivers: there may be broadcasts that are sent -before- a particular tab is opened.
I tried to work around this by:
Setting my receivers as static and registering from somewhere else. This is not possible because I need to call into methods.
Calling into tabHost.setCurrentTabByTag(the_tag) and then switching back to my root tab. This only works sometimes and this is a very ugly solution imo.
Not using activities but just using views instead. Also not a very elegant solution because it turns my tabHost activity into one huge master class doing all kinds of unrelated things.
It is observed that while entering text in password mode, first the text is displayed and then after 1 second the asterisk (star) is displayed. Is there no way to directly display the asterisk? code: mInputPwd.set Transformation Method (android.text.method.PasswordTransformationMethod.getInstance()); in xml: android: password = "true"
My application contains 2 activities A and B. B is opened with startActivity(intent) in A, when B is closed with finish(), I found the method finalize() of B is not called.
My question is: How to force Activity to call finalize() when it is closed with finish()?
I'm writing a widget with a configuration activity which calls the following method when its OK button is clicked:
CODE:..............
This is almost verbatim from the documentation. widget_id holds the widget ID that was dug up during the activity's onCreate().
When I place an instance of the widget on the home screen, I've verified that I get the expected sequence of events:
onReceive() gets an ACTION_APPWIDGET_ENABLED if it's the first one.
onUpdate() gets called (in which I detect that the widget isn't configured and draw something as a default action).
The configuration activity appears.
When I press OK, the ok() method above gets called.
The method gets all the way through to the finish() and the configuration activity goes away, but there's no call to onUpdate() or onReceive() after this point. (The widget itself has no updatePeriodMillis.) I end up with a widget on the screen that has the results of my default action but never gets updated.
If I set the widget up without a configuration activity, it gets updated when created and everything works as expected (just without the configured bits).
For an unknown reason, I can't get my application leaving properly so that when I push the home button and the app icon again I resume where I was in the app....But I would like to force the application to restart at the first activity...I suppose this has something to do with onDestroy() or maybe onPause() but I don't know what to do..

I got a TabHost, and 2 tabs in it, from the tabs you can get to settings.
Refreshing the TabHost isn't an issue, as it's fairly small, however both the 2 tabs are quite large views, and having a function to manually update all the strings seem unnecessarily difficult. Is there any way to force the activity to recreate itself and trigger a new onCreate?
I tried having a static function in the tabhost that clears all tabs and recreates them, this refreshes the tab titles, but not the content in the tabs.
I have tab bar in my application .In this I have three tab .it will call three activity .in activity i have the list view .if i click the list view it will call different activity other than tab activity.can anybody tell how to display tab bar for other activity give example?

package com.mhe.test.scan;

import android.widget.Button;
import android.widget.EditText;

/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

public void onClick(View v) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
startActivityForResult(intent, 0);
} } );
} EditText totalbox = (EditText) findViewById(R.id.totalbox);
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) { if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
// Handle successful scan totalbox.setText(contents)
} else if (resultCode == RESULT_CANCELED) {

Essentially it is supposed to call zxing Barcode Scanner to scan a barcode on a button click and return the result into an EditText field.
A button on our screen causes an activity to be shown that has a "dialog" theme. We are having an issue were if you click the button quickly twice in a row, the dialog activity is opened twice.
Typically I would expect that when a new activity is started, the underlying activity is immediately stopped, and thus accepts no further input.
However, since the dialog themed activity does not take over the whole screen, I think the underlying activity is only paused, not stopped and thus the buttons are still accessible.
Which brings me to my question... Is there a way to force the dialog themed activity into a modal state where the user can't click the buttons on the activity below?
I could probably manually accomplish this by disabling everything in onPause, and reenabling it in onResume, but this seems like a lot of work!

View 6 Replies View RelatedSo I read through the SDK docs and I thought that calling a new activity(browser) as part of a task (myTask) will mean that activity* (browser) will close when a user closes the task (myTask) But I am left with a browser window.

I was wondering if it is possible to force the RecognizerIntent Activity (or any other Activity) to stay cached so that the launch time would be faster.
View 2 Replies View RelatedI have a language setting in my application. When the language is switched, I would like all the textviews etc to change language immediately. Currently I just change the locale in the configuration, so the language has changed when the user restarts the activity.
Solution to my problem would be to make each textview load the new resources each time the language is changed. Is there a better solution? Perhaps a neat way to discretely restart the activity? Or maybe just force reload of the resources?
I am new to android.I have a list view in one activity. Displaying data in it... I want to use another activity as a tab-bar for 1st activity which allow user to switch to other activity... Is there any way so that 2 different views can be displayed in 1 activity. And then how can i start a new activity inside this activity. Like when user click on any button in tab-bar the corresponding activity should be start but we should not Re-initiate tab-bar view...
