Android :: Using Edittext - Create A Login Screen
Jun 21, 2010
I've got a few questions about edittext..
I'm trying to create a login screen on Android. I'm taking in a username and a password and then sending the results to another method. I've just got a few questions about it...
1) If I have two edittext's and the user enters values in both and then hits a "login" button, I want the button to take the values that were entered in the 2 edittext boxes, convert and save them to a string and then pass them to a function. I'm unsure how I'd construct this button. The problem I'm having is making it a string I'm currently doing this.. String user = edittext.getText();
But that doesn't seem to work. Also I'm unsure what way Android saves Edittext inputs.. Will it just automatically save it to the string once the user is no longer working out of the box? e.g will...
CODE:........
work? If not how would I define it?

I've downloaded a few networking apps (games) that have you log in, then take you to a "home" type screen where you can change your settings, or start a new game, or view your buddies etc.My question is two-part:
1) how are these "multipanel" apps created? Is each panel its own activity? I've tried adding different panels through Views, but on the apps I described above, when I hit the back button on my phone, it takes me to the previous screen and in my apps, it just takes me out of the app when I hit back (again I'll I've done are add separate views). Can someone point me in the right direction of what I need to do to create a multipanel application that when I click a button, a new panel loads, then when I hit back on the phone, it takes me to the previous panel?
2) one of my panels will be a login page which I will post the log-in credentials via http post to my server for authentication. I would like to remember the log-in "token" that is passed back to the client so they don't have to log in every time they use my application. Again, referring to some of the apps that I have, they offer this feature but I can not locate anything on the phone where it would be saved. Is this done with xml usually?

Is it possible to create a custom dictionary for an edittext? In other words, can I create a custom list and have the edittext only suggest names from that list? I don't need it popping up useless word suggestions when the user is inputting specific names of people.

I managed to create the logic for the function but I have no idea how to match it with the database. I only know how to do it the hardcoding way.
Below is how I did it. I believe an sql statement should be inserted there am I right? And I know I missed out something. Before I match the username and password, I should check whether the user exist in the database first, and then check whether the password match with the username.
So in conclusion I need help on the 'if else' statement.

I don't have my phone encrypted but I always have it password protected. I updated my Droid RAZR MAXX HD to KitKat 4.4.2 and discovered Swype was no longer bundled with Android. Straight to the PlayStore to get Google Keyboard (aka the old familiar Swype but significantly upgraded). As I had configured previously before the KitKat update, I had Swype as my default keyboard and all other keyboards disabled. So I went to settings disabled the default keyboard and enabled Google Keyboard and Voice Input. Later I went to use my phone and was presented with the expected login screen but saw a spinning red microphone with "Speak Now" and "Waiting for results". No keyboard. Tapping on the red microphone did nothing. Calling the Droid from another phone allowed a keyboard icon to appear to the left but tapping it did nothing (since it was disabled).
It appeared to me after research for several hours most people had not disabled their Default Keyboard and could recover from this. Since I had disabled mine, I have concluded that mine was bricked and left with only a factory reset.
In conclusion, Google Keyboard still has some bugs if it can't handle the login screen. This seems like a precondition to releasing this keyboard software to the community.

In most tutorials is how to display only one of them, I noticed to display an array, main class should use interface from ListActivity, but when i try display something else (like my edittext box) program crashes.
Somebody suggest me To display an array like that:
ArrayAdapter<String> myAdaptor = new ArrayAdapter<String>(this,R.layout.test,myStrings); myListView.setAdapter(myAdaptor);
but this is not doing anything.
Can anyone tell Me what is wrong in this lines or explain me how to solve my problem?

Adding an image on EditText works fine. However, copying an image is another problem. When I insert an image on EditText by using ImageSpan it shows correctly, but I copy inserted image, EditText shows me only 'obj'.

I want an EditText to look like TextView but still behave like EditText. I've tried applying TextView style to my EditText in my layout.xml file, like this:
CODE:............
But I get an error within xml editor: "Error: No resource found that matches the given name (at 'style' with value '@android:style/ Widget_TextView')." It is strange because @android:style/ Widget_TextView definitively exists - I double checked it in code via android.R.style.Widget_TextView. Another strange thing is that I don't get android:style offered in the xml editor while typing? There is android:id, android:text and everything else.. but not android:style?
I consider the hard way (making EditText look like TextView) to be: extending EditText and overriding it's onDraw method.

I found that when EditText in placing at the bottom of screen, and the activity's android:windowSoftInputMode="adjustPan", and the apps run in ldpi(240*320) mode, then when EditText has focus, the content of the activity is panned too far to the above, thus leaving a blank screen between the content of the window and the soft input panel.
You can see the screenshot of this problem at
https://sites.google.com/site/wilderwang/android
Also, the source code to repro this problem can also be get at
https://sites.google.com/site/wilderwang/android
When I test further, if the same apps run in hdpi(480*800), when EditText got focus, the content of the window panned too small thus causing the soft input window cover the EditText view. It seems the distance of the window panned not compute the screen density.

Hopefully this is just something easy since I'm still wet behind the ears with programming for android. My issue is that i have a couple EditText boxes at the bottom of my layout. When in the emulator they work as expected, you touch the edittext and the screen scrolls up so you can see the content. However when i try it on my droid inc the edittext is covered by the keyboard.

I have a long scrolling list of EditText items created by a SimpleCursorAdapter and prepopulated with values from an SQLite database. I make this by: cursor = db.rawQuery("SELECT _id, criterion, localweight, globalweight FROM " + dbTableName + " ORDER BY criterion", null); startManagingCursor(cursor); mAdapter = new SimpleCursorAdapter(this, R.layout.weight_edit_items, cursor, new String[]{"criterion","localweight","globalweight"}, new int[]{R.id.criterion_edit, R.id.localweight_edit, R.id.globalweight_edit}); is.setListAdapter(mAdapter); The scrolling list is several emulator screens long. The items display OK - scrolling through them shows that each has the correct value from the database. I can make an edit change to any of the EditTexts and the new text is accepted and displayed in the box. if I then scroll the list far enough to take the edited item off the screen, when I scroll back to look at it again its value has returned to what it was before I made the changes, ie. my edits have been lost. In trying to sort this out, I've done a getText to look at what's in the EditText after I've done my edits (and before a scroll) and getText returns the original text, even though the EditText is displaying my new text. It seems that the EditText has only accepted my edits superficially and they haven't been bound to the EditText, meaning they get dropped when scrolled off the screen. Can anyone please tell me what's going on here and what I need to do to force the EditText to retain its edits?

Our app (WordPress for Android) uses a ScrollView for the new blog post view. The issue is that if a user writes a lengthy blog post in the EditText, they are unable to scroll inside of the EditText because the ScrollView seems to be taking over the scrolling action, even when you are in the EditText.
Here's the layout XML (the EditText in question is @id/content):

Every time I put a TextView before an EditText element in a LinearLayout, the EditText does not show. When I don't, it does.
I've narrowed the problem down to the TextView's layout_width attribute. If I give it "wrap_content", it works, but doesn't "block" down, and it appears on the same line as the EditText.

Whenever I add an EditText widget to the layout of my home screen widget (confusing how the term "widget" is being used twice in the Android lexicon :-/ ), I receive the "Problem Loading Widget" error box.
Here is the layout I'm attempting; if you remove the EditText, it works.... code...
Now, the Google Search home screen widget has an EditText, so it's obviously legal to implement. Any thoughts on why this is not working?

CODE:............
I have this at the top of my application. When the application starts, the EditText is orange highlighted and has a cursor in it; when the EditText is tapped, the soft keyboard pops up. The user uses it to type into the EditText.
However, when they click the Button, my onClick method fires and does everything it's supposed to, however the soft keyboard stays on screen and the EditText is still highlighted with its cursor.
I also have, at the top of the Button onclick: findViewById(R.id.name).clearFocus();
In spite of this, the EditText does not seem to clear its focus. How do I make the button actually act as if it is submitting the form?
Also, I do not transition to a different Activity on the click of the Button. I suppose that is the typical case, and probably the reason why they don't bother hiding the keyboard. However I want to keep the search box and button at the top of the screen, so I just dynamically fill and add views to the screen when the Button is pressed. How can I achieve my desired behavior?
