问题 How to smooth scroll to the next item in the listview after user click on yes or no radio buttons in radio group. For example. If user answered yes or no to the first question it should smooth scroll to the second question. I found the below code and it is working with static position value, but I don't know how to scroll to the next index(next question) on select of radio group(yes or no radio buttons). int index = 0; int h1 = simpleListView.getHeight(); int h2 = simpleListView.getHeight();

问题 I can't get the below dynamically generated RadioButtons to uncheck when I click on other RadioButton in the same RadioGroup. I have even resorted to writing my own handler that clears the RadioGroup (below), and tried another that make all RadioButtons .setChecked(false) but this still does not clear the RadioButton that I setChecked in PopulateAccessPoints. Any ideas? RelativeLayout rlaAccessPoints; RadioGroup rg; public void onRadioButtonClicked(View view) { // Is the button now checked?

问题 Is there a way to set the selected index of a RadioGroup in android, other than looping through the child radiobuttons and selecting checking the radio button at the selected index? Note: I am populating the Radio Button Group at run time. 回答1: If your radio group is defined in a layout xml file, each button can be assigned an id. Then you just check a button like this radioGroup.check(R.id.myButtonId); If you created your radio group programmatically (I'm not even sure how you do this...),

RadioGroup currencySettingRadioGroup = (RadioGroup) currency_settings_dialog.findViewById(R.id.rg_currency_symbol); currencySettingRadioGroup.removeAllViews(); RadioButton rb_none = new RadioButton(this); // Add the 'None' option at the start rb_none.setText("None"); if (v_currency_symbol.equals("")) rb_none.setChecked(true); currencySettingRadioGroup.addView(rb_none,0); String[] currency

问题 I am getting the value from DB and setting it to the respective button in the below format. Is there any optimised way to do the same. All these radio buttons are inside a radio group. if (bundlevalue.get(3).equalsIgnoreCase("Mr.")) { rg_nametitle.check(R.id.mr); } else if (bundlevalue.get(3).equalsIgnoreCase("Mrs.")) { rg_nametitle.check(R.id.mrs); } else if (bundlevalue.get(3).equalsIgnoreCase("Ms.")) { rg_nametitle.check(R.id.ms); } else { rg_nametitle.check(R.id.messrs); } 回答1: You can

问题 I want to achieve Single RadioGroup like below image for blood group selection. How can this be done? 回答1: I created my own RadioGridLayout which include RadioGroup code and extends GridLayout. You can copy this code. For me working well. After you can use this layout in your xml and customize like grid layout. For R.styleable.RadioGridLayout_checked I used code like this: <resources> <declare-styleable name="RadioGridLayout"> <attr name="checked" format="integer" /> </declare-styleable> <

问题 I'm trying to create a 2x2 array of radio buttons, but I don't know how to customize layout other than horizontal or vertical. Any ideas? I've only gotten A B C D and A B C D but I want to have A B C D EDIT: I resolved this issue. For anyone wondering, I set up two individual radio groups (i.e. one with AB and one with CD). I set onClickListener() for each RadioButton, and used clearCheck() on the second RadioGroup when a button in the first RadioGroup was clicked, and vice versa. 回答1: You
