Android :: Alert Dialog (As Login Or Pin Code) Input Text

Jun 10, 2010

I'd like to use AlertDialog as a Login or pin code or password dialog. Here is my code -

AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Login"); alert.setMessage("Enter Pin :");
// Set an EditText view to get user input final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText().toString();
Log.d( TAG, "Pin Value : " + value); return;
} } );
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub return;
} } );
alert.show();

How to code that all input text will appear like ' * ' - asterisk. I can't get my pin code value although it shows into asterisk. my code is below

private void accessPinCode_2() {
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.dialog_login, null);
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Login"); alert.setMessage("Enter Pin :");
alert.setView(textEntryView);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//String value = input.getText().toString();
EditText mUserText;
mUserText = (EditText) textEntryView.findViewById(R.id.txt_password);
String strPinCode = mUserText.getText().toString();
Log.d( TAG, "Pin Value : " + strPinCode); return;
} } );
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub return;
} } ); alert.show(); } } dialog_login.xml
<?xml version="1.0" encoding="utf-8"?><EditText xmlns:android="http://schemas.android.com/apk/res/android"
id="@+id/txt_password"
android:password="true"
android:layout_height="wrap_content"
android:layout_width="250px"
android:layout_centerHorizontal="true"
android:layout_below="@+id/password_text"
android:singleLine="true" />

I entered the value, but get null! How to solve? Debugging is stopped at this statement. When I pointed above mUserText null value being shown in popup.
String strPinCode = mUserText.getText().toString();
I use Android 1.6. Does it depend on Version?

Android :: Difficulty Displaying Alert Dialog - Why Does This Code Force Close App?

Jul 18, 2010

I'm very new to Android so I've been working primarily with information from the android developer's page. Everything was going great until I added the code from the alert dialog section. The code they give alone gives me an error when I try to run it on the last line, saying I must initialize dialog, but I feel like I'm getting the NullPointerException no matter what the case is.If I don't instantiate "dialog" to "null" at the beginning, I cannot run the program. I'm not even trying to do anything crazy yet, any help would be great because I'm having alot of trouble trying to figure out what exactly this code is trying to do.

Android :: Error Using A Custom Text For Alert Dialog

Apr 3, 2010

My requirement was to invoke a alert dialog with a string text that gets modified dynamically when the user hits a button every time
for example:
string str="you have clicked "+ count + "times";
where count is an integer variable that gets incremented every time the user hits a button. and when i assign this string to the text of an alert-dialog ,i get the alert-dialog at runtime but with an empty text value...ie. a naked alert-dialog with just OK cancel button.

Android : Alert Dialog With Dynamically Changing Text On Every Request

Jun 5, 2009

I want to show an AlertDialog with one option that might change on every request. So for example at one time I want to show the option "add to contacts" while another time it should be "remove from contacts".

My code does work on the first time, however Android seems to cache the AlertDialog so that onCreateDialog is not executed next time. Therefore the option doesn't change anymore. Can I prevent this caching, or is there just another way of changing the option?

I am working with SDK 1.5 but using 1.1. Code...

General :: Black Text On Dark Background In Alert Dialog On Gingerbread?

Jan 17, 2013

I'm on JellyBlast 3 (Gingerbread, I guess) with my Galaxy Y and I'm a little unhappy with the theme that comes with JellyBlast. I have fixed some issues but I cannot figure out how to avoid black text on dark background in Alert Dialogs. This issue makes some dialogs of the hololauncher and some other apps completely ureadable if you do not turn the screen to full brightness (what I normally don't do).

What I've found out so far: In the Gingerbread source the Theme for the the Alert Dialog is hard coded:

Code:

protected AlertDialog(Context context) {
this(context, com.android.internal.R.style.Theme_Dialog_Alert);
}

I'm not yet allowed to post external links... I found the above on github in the gingerbread branch in platform_frameworks_base -> core -> java -> android -> app -> AlertDialog.java

The hololauncher uses the AlertDialog.Builder class to create the Dialogs and it uses a TextView Widget to display the text. The layout looks like this:

Code:
<?xml version="1.0" encoding="utf-8"?>
<TextView android:textAppearance="?android:textAppearanceLargeInverse" android:gravity="center_vertical" android:paddingLeft="15.0dip" android:paddingRight="15.0dip" android:layout_width="fill_parent" android:layout_height="wrap_content" android:minHeight="?android:listPreferredItemHeight" android:drawablePadding="14.0dip" />

Here you see, that the textAppearanceLargeInverse definition of the theme is used as text color. And the theme should always be "Theme.Dialog.Alert" since this is hardcoded.

I assume that com.android.internal.R.style.Theme_Dialog_Alert refers to the Theme.Dialog.Alert styledefinition in the ROMs framework-res.apk. So I added the following line to the styles.xml in framework-res.apk -> values/styles.xml inside Theme.Dialog.Alert:

Code:
<item name="textAppearanceLargeInverse">@style/TextAppearance.Large</item>

I hoped that this would overwrite the definition of textAppearanceLargeInverse for the AlertDialog so that I will not use the inherited definition of the dark theme. The color that's referenced by @style/TextAppearance.Large is (contrary to ...Large.Inverse) is #FFFFFFFF or at least close to it.

Unfortunately this does not work and I do not understand why. I got that far to figure all this stuff out and my phone seems little impressed by my effort. It still displays dark text on dark background.

Android :: How To Repeat Login Dialog And Progress Dialog?

Jan 25, 2010

I am having a problem about repeating Login dialog (an AlertDialog) and progress dialog, coordinating with http thread. I suppose repetitive Login dialog (if fail, continue) handling should be common and straightforward. I guess my approach must be wrong somewhere. I already spent 2 days on this and am desperate. So please help. User starts the app, the main activity starts.Show a login dialog (generated by the main thread, i.e. from on Create. The main thread then starts a wait_thread, which will wait for http to return data and check the data and decide what to do.After user input username/password and press login, a progress dialog starts.The progress dialog starts an http_thread to talk to the server and get replies. Once done, it will notify the waiting thread.If the user type in the right username password first time, the code works fine.But it always fail for 2nd time Login, i.e. When first login fail(wrong username/ password),the wait_thread will generate 2nd Login dialog to let user repeat the login process. But after user hit the login on this 2nd Login dialog, the system always crashes.

Android :: Invisible Alert Dialog?

Oct 22, 2010

Believe me, I am not trying to create an invisible AlertDialog. But I believe I have one. I'm not making this up. Behavior: main activity starts and is completely unresponsive. No dialog appears. No Force close/ANR appears even after much time in this state. But if I push the back button, it becomes responsive again. This does not occur when debuggable is true in the manifest, so I can't investigate using the debugger. But I found out the following with log statements. MainActrivity:OnCreate starts another activity, a welcome screen. Main Activity: OnResume is called while the other activity is visible. OnResume creates the dialog and calls dlg.Show(); WelcomeActivity is dismissed. MainActivity:OnResume is called. The OnResume method is smart enough to note that the dialog has already been shown and does not create it again. MainActivity is unresponsive. No dialog in sight. When I push the back button, a log statement confirms that the OnCancelListener is called on the dialog. This is Nexus One with 2.2.1. As cool as an invisible dialog is, I'd rather not have it. Can I fix it?

Android :: Results From Alert Dialog Inline

Oct 10, 2010

Is there a way to get alert dialog results inline (like you can with most dialogs)? I want to determine what to do next inwith a dialog, but I can't figure out how to get the results back in the same method that I create the dialog from thus allowing me to continue in my logic flow.

void doStuff() { dlg = CreateDialog() dlg.show(); // shows the dialog and doesn't return till the dialog is dismissed

if dlg.getResults() == this) { doThis(); } else { doThat(); }

}

Android :: Button Mashing Alert Dialog

Sep 24, 2010

So I have a fairly simple droid app. Part of it is a waterfall of alertdialog boxes makeing sure everything is ready to show the final display. Example Check GPS If (no GPS){ alert.show} The alert has one button that first dismisses the dialog, then performs the check again, and displays another dialog box if GPS is still not enabled.

This all works great if I go at a normal pace. But if I button mash the alert dialog button, eventually I get many alert dialog buttons on top of each other. The program still works, ya just gotta close all of them. .............

Android :: Using Cursor With SetMultiChoiceItems In Alert Dialog

Aug 30, 2010

I want to display a multichoice list in an alert dialog box. If I'm using an array to store the list of items, then it is working fine :

d.setMultiChoiceItems(R.array.items,
new boolean[]{false, true, false, true, false, false, false},
new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int whichButton,
boolean isChecked) {

/* User clicked on a check box do some stuff */
}
})

But in my case, the item list is dynamic, which I'm geting from a database. The database keeps on updating its contents and hence the list is also updating at a fixed interval of time. So, instead of using an array I would like to use a cursor in the argument of setMultiChoiceItems.
