Edittext “lag” android

由 醉酒当歌 提交于 2019-12-06 10:44:30
The first time i focus an edittext view i notice a lag of one or two seconds before i can write anything in the textbox. I notice this behavior even on an app without any code more than what's nessecary to initialize the application. What am i doing wrong? I've INSTANTLY fixed this issue for me; I saw in the DDMS that a lot of redraw's and recalculations were occurring while entering text, and a lot of info about RelativeLayouts were being called. So, I checked my layout; i had some Multi-Line EditText's who were direct children of a RelativeLayout. So, I wrapped those up into a Linear Layout,

问题 I have a EditText that should not allow the user to input anything through the keyboard (soft or hard).

问题 I have an activity that only has a EditText. I want the soft keyboard to show up automatically. How can I do this? 回答1: You can use this onResume: InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); imm.showSoftInput(((EditText) findViewById(R.id.your_view)),InputMethodManager.SHOW_FORCED); I suggest that you check if there is a Hardware keyboard before you force the keyboard to appear. To hide: ((InputMethodManager) YourActivity.this.getSystemService

问题 I'm trying to implement android:scrollbars="vertical" in XML by Java code. I've tried method setVerticalScrollBarEnabled(true) but it doesn't work. Anyone can give me a suggestion?

EditText data is lost on rotating the device

由 筅森魡賤 提交于 2019-12-06 08:30:01
OK guys, I am done with it. I have been googling for last 2 days but I can't find the exact solution. Everyone is talking about configChanges and all those cliche things which do not seem to work in my case . I have a login screen which consists of 2 EditTexts. Now this login screen has different layout for both Portrait and Landscape orientation . So I had to create one login.xml in layout folder and another login.xml in layout-land folder. And to support orientation changes I overrid onConfigurationChanged() method in LoginActivity class. In this method I call setContentView(R.layout.login)

Android Create aligned fields Layout

由 一世执手 提交于 2019-12-06 08:14:01
Here's my issue I have a login and want to line up the EditText fields. See the mockup picture attached . I have tried a few ways and cannot figure out how to make the fields lineup. I really hate layouts in Android I spend more time just messing with things to line up right. Wish they would just scrap it and use something more intuitive, as its more like using tables in HTML. So in advance thanks for your help and cheers! You could probably play around with RelativeLayout and get just what you want. Here's an approximation with TableLayout . <?xml version="1.0" encoding="utf-8"?>
