问题 UPDATE - my working solution: https://stackoverflow.com/a/21233824/902172 I am trying to implement the layout below: I guess GridLayout is suitable for my needs but after 2 hours of struggle I couldn't create even a similar layout.. The layout is resizing itself wrongly , it exceeds the screen of the phone and it also does not span the specified rows and columns.

问题 I am using a web view in which I am adding an image view. How can I set the background of this image view to transparent? I have tried this: mImageview.setBackgroundResource(R.color.trans); Where trans → <color name="trans">#00000000 </color> . 回答1: In your XML set the Background attribute to any colour, White(#FFFFFF) shade or Black(#000000) shade. If you want transparency, just put 80 before the actual hash code: #80000000 This will change any colour you want to a transparent one.. :) 回答2:

问题 I have an EditText field for the user to enter their weight in lbs. How can I override the traditional keyboard and display the numeric keypad instead? 回答1: This didn't work for me. However, I was able to accomplish the aforementioned by either of the following lines: // TYPE_CLASS_NUMBER: Class for numeric text. This displays the numbers/symbols keyboard. editText.setInputType(InputType.TYPE_CLASS_NUMBER); // TYPE_CLASS_PHONE: Class for a phone number. This displays the phone number keypad.

问题 I want to force a widget to appear on the lock screen in Android. Any ideas or code examples? Thanks in advance. 回答1: First, the standard Android lockscreen framework only supports app widgets from Android 4.1 through 4.4, which is a steadily shrinking portion of the Android device ecosystem. Second, there is no programmatic means, in standard Android, to force the user to add an app widget to the home screen or to the lockscreen. 来源： https://stackoverflow.com/questions/41840622/how-to-force

问题 I am trying to make the Gallery scroll with animation to left or right when user click on either the left or right buttons. It works well if I use the below code to invoke the keyevent to scroll the gallery: gallery.onKeyDown(KeyEvent.KEYCODE_DPAD_LEFT, new KeyEvent(0, 0)); or KeyEvent evtKey = new KeyEvent(0, KeyEvent.KEYCODE_DPAD_RIGHT); gallery.dispatchKeyEvent(evtKey); But once I set any value to the Gallery spacing, the code above stop working.

问题 I have a ExpandableListView that works properly with JSONObject. When I click on group, the children are showed. Children represent comments and, in my case, the last child is ever a EditText. By this EditText I can insert a new comment. The problem is this: if in my adapter I use myEditText.requestFocus() the keyboard works, I mean when I type on it editText is update with characters, but often I have to push more than once on EditText to see the keyboard. If in my adapter I don't use

问题 According to the documentation on onAppWidgetOptionsChanged in AppWidgetProvider: "This is called when the widget is first placed and any time the widget is resized." However, when I place my widget on the stock launcher in Android 4.2 and 4.3, this method is not being called immediately (only after I resize the widget). I tried it on my own app, as well as CommonsWare's https://github.com/commonsguy/cw-omnibus/tree/master/AppWidget/Resize Is there something I am missing? EDIT: The only
