android-radiobutton

问题 In my android application using radio buttons to select screen view. I want radio button equally aligned horizontal. I tried layout xml shown below. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Views" android:paddingLeft="10dp"

问题 I'have tried lot of combination both with xml and programmatically but nothing to do yet. This is the scenario (pay attention to the small red arrow): I have some RadioButtons inside a radio group, in xml this scenario could be represented as: <RadioGroup android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:id="@+id/radiobuttons" android:paddingBottom="@dimen/activity_vertical_margin" android:dividerPadding="30dp"> <RadioButton android

问题 I'm trying to make a custom RadioButton like this: I tried making a RadioGroup with three RadioButton in it with the background of the RadioGroup being a rectangle and the background of the RadioButton would be a blue rectangle when checked and white when not but it doesn't seem to be working. <RadioGroup android:id="@+id/Frequency" android:layout_width="370dp" android:layout_height="40dp" android:background="@drawable/radiorectangle" android:orientation="horizontal" app:layout

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 I can set the shared preferences in a AlertDialog with some radio buttons: public void ShowRadioDialog() { SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this); final SharedPreferences.Editor editor = preferences.edit(); SharedPreferences choiceSettings = getSharedPreferences("currentChoice", 0); final int[] currentChoice = {choiceSettings.getInt("currentChoice", 0)}; final CharSequence[] items={"Rosso","Verde","Blu","Giallo","Arancione"}; AlertDialog.Builder

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...),
