Android :: Blank Screen Appear When EditText Get Focus In IDPI Mode
Oct 10, 2010
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

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.

I had a older dinc. that had 2.1 on it and it got broke so i got a new incredible that has 2.2 factory on it. i went thru the root process, and rooted it using the guide and everythign looked ok and went thru fine. "s" off and everything. well when you go into recovery mode, it goes to a blank screen and has the two white bars on each side of the screen. i thought i had this fixed with a link that had a update that i ran. now it is happned again. also when i tried to download a new rom and went to install it gets hung up in the htc screen for 45 min and during the process it seems to have bries screen flashes of siff colors... im not a pro at this but when i had my old dinc, never had any problems rooting or changing roms or anything... is there something missing? should i downgrade to 2.1 on this on and try to go that route?

How can we prevent an edittext from getting focus and displaying the soft keyboard. I have an searchbox which should not be focused by default and should have focus only when user clicks on it to enter something. But right now it takes focus and shows the keyoard as soon as I open the activity. Is this a bug or can this be changed to behave in the way we want?

I have an activity with two edittext controls. I am calling the requestFocus on the second edittext field since by default the focus goes to the first edittext control. The focus appears to be in the second edittext field (the second one gets the highlighted border), but if we try to enter any characters using the hardware keyboard the text appears in the first edittext control.

In my application I have a single EditText together with some TextViews, button and a spinner. My EditText receives focus since it is the only focusable view in this activity, I believe. My EditText shows with an orange border and cursor on the field. Now I would like to remove the focus from this field (I don't want the cursor and border to show). Is there a way to do this? I have been able to focus on the button by doing button.seFocusableInTouchMode() and button.requestFocus(). But this highlights the button and is obviously not what I want.

If I want to enforce a maximum length of input in an EditText field, I can use the maxLength attribute. But if I want to enforce a minimum length (in my case, simply non-blank), I find no corresponding minLength attribute. I've also looked at the various 'inputType' attributes (phone, password, etc) but I don't see anything like 'required' or 'non-blank'. I can't believe this would require a custom input filter; it's more likely the answer is so obvious it just doesn't get written down in the form I'm asking the question.

The home screen of my Android application has three EditText views, meant to be used as three different search functions, each with a "Search" button. The app works perfectly on the device (G1) when using the trackball: I can move between the EditTexts with the trackball, all the events fire as expected, I can enter text using the physical keyboard in the selected EditText, Enter correctly submits the proper search, etc.
However, I can't switch between the EditText views using touches - only by using the trackball. Touches seem to be completely ignored by the EditText. Touches do fire for the buttons, but very hard - takes a lot of tries to make a touch register. In the simulator, clicking on any EditText does nothing - the first one always remains selected, and I never get a soft keyboard. This is all inside a TabHost - I've read there are some problems with that configuration, but it sounds like a slightly different issue (the EditText doesn't seem to lose focus - everything works perfectly with the trackball).

I make ListView that has some items that has one EditText and one ImageButton. When touch the EditText in ListView's Item, Keyboard was appeared but EditText lose focus. What can I do for resolve this problem? I can use ScrollView instead of ListView by addView in ScrollView. And in ScrollView, when I touch the EditText, keyboard was appeared and EditText keep the focus. But I must optimize the list because the list may has many items. In ListView, I can optimize list in getView. But in ScrollVIew, there was not way to optimaize list. So, I must use ListView.

I'm showing an input box using AlertDialog. The EditText inside the dialog itself is automatically focused when I call AlertDialog.show(), but the soft keyboard is not automatically shown. How do I make the soft keyboard automatically show when the dialog is shown? (and there is no physical/hardware keyboard). Similar to how when I press the Search button to invoke the global search, the soft keyboard is automatically shown.

I can't seem to focus on anything closer than 4 inches, even if there's nothing behind it. Touch-focus isn't helping either. Is there a macro mode?

This was reported in the other thread about X8 Issues, but thought to start a new one to gather feedback from users. It's about the ''black screen'' freezing issue encountered by some users. I have had this several times since owning the phone for a few weeks, so it is a recurring issue. Problem: The phone hangs or appears to be shut down or become unresponsive suddenly. Pressing the hardware buttons doesn't help as the phone doesn't react at all. Solution: Take out cover and battery and restart.Observations: From my own observations, it's not actually a shutdown but a major freezing/hanging. Sometimes when it happens, I can still see vague shades of the display at an angle. After leaving the phone for a while in the pocket, the phone comes back to normal again. Not sure if this is true for all users with this problem. Anyway, gathering more feedback to see how prevalent the problem is, to evaluate whether I should take it to the SE service centre, or whether doing so will help at all.

My app has one activity and one ContentProvider, the activity is simple in that it's just a splash screen at the moment with no other logic in it (I do intend to have more activities in the app). The ContentProvider uses SQLite as a back end and loads some static data from files on first install, a slow process due to file sizes and database initialization. My problem is that I want the activity to show up as soon as the install starts and maybe display a progress bar or dialog to show the user progress about the install. At the moment I get a blank (white) screen while the ContentProvider is initialising the data which takes quite a long time and I get "Activity idle timeout for history record" warning in LogCat. My splash screen only shows when the Content Provider is done, from the app standpoint this is undesirable behaviour. One potential solutions would be to manually start the provider via an AsyncTask but I have a feeling that this is a bad approach due to the fact that if the activity is interupted and restarted while the install is underway and a new AsyncTast is created through the activity's onCreate() then I'll have worst problems on my hands. Is there a way to start the content provider in the background and display my splash screen activity straight after the app is started? Note that this problem is only an issue on first install.

While opening my application from application launcher. Sometimes I am getting blank screen for long time (almost 3 min). If I perform some key events then I am getting ANR. Log is as follows.
I/ActivityManager( 57): Starting activity: Intent {
action=android.intent.action.MAIN categories ={android.intent.category.LAUNCHER} flags=0x10200000 comp={com.test/com.test.MyScreen} }
E/JavaBinder( 57): !!! FAILED BINDER TRANSACTION !!!
After this I am getting activity launch timeout and Idle timeout. Is there any design issue with my activity or problem with android environment.

I've got a basic list activity with a few images that when you select one starts a new activity with a SurfaceView (based on the Lunar Lander sample). Some times the screen is just blank, from some debugging I can see that the background .png is being loaded and doDraw() is being called by the activity doesn't display anything for anything from 4 to 20 seconds. Other times the game activity is loaded just fine. I assumed it was some kind of garbage collection problem but I can't see anything in LogCat and the second activity is actually loaded, just not displayed for some reason.

We are developing an application that requires a download of a music file (mp3). We are using the Browser Activity for the same.
The Browser Activity is invoked from the application and the download url is passed to it, like: startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(downloadurl)));
However, after downloading, on the download list page, if we press the Back button, a blank white screen is displayed. Only after we press the Back button a second time on this white screen, the application screen is displayed. This happens because the Browser Activity view is displayed before the actual downloading starts.
This is an issue in the application flow. We need to manage the flow in such a way that the 'Back' key press on the download list view will take the control to the application screen instead of the white screen.

Some background info: I got an HTC Evo a few days after the initial launch. I had no problems with the screen at first at least for a few weeks. Then all of a sudden, the screen would go blank after I took the phone off the charger, or would finish a call, and a few other instances. After dealing with that for a little over a week, I took the Evo back to sprint and got a brand new one. I looked all over the forums, but could not find any answers. I know some others are having this issue, but it doesn't seem that widespread. So I get the new phone, and for the first day, I don't install any of the apps I had on the last phone because of a lack of time. No problems to report the first day of use, so I think I'm in the clear. The next day I start installing all of the apps I had on the first Evo, and bang, it starts to happen again. The screen goes blank, and I can do nothing to turn it on except to pull the battery out and restart the phone which is a monster pain. After all of this, I have to think its a software issue. Some app I have running could be causing this? How likely is it that 2 Evo's have this exact same problem, and that it's hardware related? Here is a list of apps I have installed on my phone: maui9111's Apps on the phone. I tried uninstalling several of them, but still can't find the solution. Anyone have any ideas? I love this phone, but this issue is driving me nuts!

I'm running a standard camera preview (i use the camera api demo as a reference).
When i hit the capture button, there is a black screen for a good 1/2 second until the captured image appears.
My question is how can i freeze the last image being previewed on the screen while i do the capture work ? I don't mind that the quality of the displayed image is not as good.
If i hit camera.stopPreview() -> that goes into the black screen which i don't want.
