问题 I dynamically created buttons through code rather than from XML. The code is as below : dynamicview = (LinearLayout)findViewById(R.id.llayout); LinearLayout.LayoutParams lprams = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); for(int i=0;i<nob;i++){ Button btn = new Button(this); btn.setId(i+1); btn.setText("Button"+(i+1)); btn.setLayoutParams(lprams); dynamicview.addView(btn); } I am not finding a way in which I can implement

问题 I have a widget that is using a collection. What I need is to pass an id, from the widget, to an activity in my app when one of the rows of the widget ListView is selected. For some reason, when I debug activity, the wrong id is being sent. I've narrowed it down to something with the position. If I pass the position to my activity when I debug, it is the wrong position It may just be my misunderstanding of how a widget with a collection works, since it's my first one.

问题 How do I add a button to a widget, not for opening an activity or something? Just for toggling for example Wi-Fi :) Could it be done by a ImageButton or something like that? I just can't figure out how to add an onClickListener. 回答1: I have updated my answer now that I understand you are trying to write an AppWidget. AppWidgets support only a limited set of Views and ToggleButton is not one of them. The list of Views supported by AppWidgets can be found here: http://developer.android.com

问题 I have a simple DatePickerFragment that extends DialogFragment. I'm wanting to set a validation callback so I can prevent "OK" being selected if an invalid date is picked. I first tried setMaxDate and that grays out the invalid choices but still allows them to be selected and OK to be pressed.

问题 I am trying to place tabs on the bottom of the screen and have each tab display a different activity. However from what I have read you can only use this on phones 3.0+. When most phones I know are around 2.3 this seems a little ridiculous. Anyone have any ideas? 回答1: This can be implemented using the android usual tab,just you have to do is add some extra codes in the xml.I hope this piece of code will help you for getting it done... <TabHost android:layout_width="fill_parent" android:layout
