Crear un diálogo personalizado con la lista de botones de radio.

Question

Tengo un método en el que tengo una lista de valores:

 /**
* ISO
* */
public void getISO(View view) {
// Open dialog with radio buttons
List<String> supported_isos = preview.getSupportedISOs();
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(MainActivity.this);
String current_iso = sharedPreferences.getString(MainActivity.getISOPreferenceKey(), "auto");
}

Este método se inyecta en onClick () de un ImageButton :

android:onClick="getISO"

Pero necesito presentar esta lista en un diálogo con los botones de radio. Posiblemente los valores de preferencia ya deberían estar seleccionados en el diálogo. ¿Es posible?

Answer 1

Esto funcionó para mí:

final CharSequence[] items = {"Option-1", "Option-2", "Option-3", "Option-4"};
AlertDialog.Builder builder = new AlertDialog.Builder(ShowDialog.this);
builder.setTitle("Alert Dialog with ListView and Radio button");
builder.setIcon(R.drawable.icon);
builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
}
});
builder.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Toast.makeText(ShowDialog.this, "Success", Toast.LENGTH_SHORT).show();
}
});
builder.setNegativeButton("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Toast.makeText(ShowDialog.this, "Fail", Toast.LENGTH_SHORT).show();
}
});
AlertDialog alert = builder.create();
alert.show();

Answer 2

Llame a showRadioButtonDialog() desde el botón.

Esto es solo un ejemplo:

private void showRadioButtonDialog() {
// custom dialog
final Dialog dialog = new Dialog(mActivity);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.radiobutton_dialog);
List<String> stringList=new ArrayList<>(); // here is list
for(int i=0;i<5;i++) {
stringList.add("RadioButton " + (i + 1));
}
RadioGroup rg = (RadioGroup) dialog.findViewById(R.id.radio_group);
for(int i=0;i<stringList.size();i++){
RadioButton rb=new RadioButton(mActivity); // dynamically creating RadioButton and adding to RadioGroup.
rb.setText(stringList.get(i));
rg.addView(rb);
}
dialog.show();
}

Su vista de diseño: radiobutton_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioGroup
android:id="@+id/radio_group"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:orientation="vertical">
</RadioGroup>
</LinearLayout>

Nota: puede personalizar su vista de diálogo (como configuración de título, mensaje, etc.)

Editar: Para recuperar el valor del RadioButton seleccionado, debe implementar setOnCheckedChangeListener listener para su RadioGroup como:

 rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
int childCount = group.getChildCount();
for (int x = 0; x < childCount; x++) {
RadioButton btn = (RadioButton) group.getChildAt(x);
if (btn.getId() == checkedId) {
Log.e("selected RadioButton->",btn.getText().toString());
}
}
}
});

Mejor y mas facil manera ......

void dialog(){
AlertDialog.Builder alt_bld = new AlertDialog.Builder(this);
//alt_bld.setIcon(R.drawable.icon);
alt_bld.setTitle("Select a Group Name");
alt_bld.setSingleChoiceItems(grpname, -1, new DialogInterface
.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
Toast.makeText(getApplicationContext(),
"Group Name = "+grpname[item], Toast.LENGTH_SHORT).show();
dialog.dismiss();// dismiss the alertbox after chose option
}
});
AlertDialog alert = alt_bld.create();
alert.show();
///// grpname is a array where data is stored...
}

Answer 4

Mira esto. Esta es la fila personalizada dialog_row.xml que debe usar en CustomAdapter:

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioButton
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>

Luego en el método onclick:

@Override
public void onClick(View arg0) {
// custom dialog
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom_layout); //Your custom layout
dialog.setTitle("Title...");
Listview listview= (ListView) dialog.findViewById(R.id.listview);
CustomAdapter adapter=new CustomAdapter(context,your_list);
listview.setadapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Do something
}
});
dialog.show();
}

Una forma limpia es así:

developer.android.com/guide/topics/ui/dialogs.html

Extracto de (Agregar una opción múltiple persistente o una lista de opción única)

mSelectedItems = new ArrayList(); // Where we track the selected items
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Set the dialog title
builder.setTitle(R.string.pick_toppings)
// Specify the list array, the items to be selected by default (null for none),
// and the listener through which to receive callbacks when items are selected
.setMultiChoiceItems(R.array.toppings, null,
new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which,
boolean isChecked) {
if (isChecked) {
// If the user checked the item, add it to the selected items
mSelectedItems.add(which);
} else if (mSelectedItems.contains(which)) {
// Else, if the item is already in the array, remove it
mSelectedItems.remove(Integer.valueOf(which));
}
}
})
// Set the action buttons
.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
// User clicked OK, so save the mSelectedItems results somewhere
// or return them to the component that opened the dialog
...
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
...
}
});
return builder.create();

Lea sobre http://developer.android.com/reference/android/app/AlertDialog.Builder.html#setSingleChoiceItems(int, int, android.content.DialogInterface.OnClickListener)

No es necesaria una vista personalizada.

cuando desee mostrar datos de la base de datos SQLIte el

private void showRadioButtonDialog() {
// custom dialog
final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.radiobutton_dialog);
List<String> stringList=new ArrayList<>(); // here is list
if (cursor.moveToFirst()) {
do {
String a=( cursor.getString(0).toString());
String b=(cursor.getString(1).toString());
String c=(cursor.getString(2).toString());
String d=(cursor.getString(3).toString());
stringList.add(d);
} while (cursor.moveToNext());
}
RadioGroup rg = (RadioGroup) dialog.findViewById(R.id.radio_group);
for(int i=0;i<stringList.size();i++) {
RadioButton rb=new RadioButton(this); // dynamically creating RadioButton and adding to RadioGroup.
rb.setText(stringList.get(i));
rg.addView(rb);
}
dialog.show();
rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
int childCount = group.getChildCount();
for (int x = 0; x < childCount; x++) {
RadioButton btn = (RadioButton) group.getChildAt(x);
if (btn.getId() == checkedId) {
Toast.makeText(getApplicationContext(), btn.getText().toString(), Toast.LENGTH_SHORT).show();
}
}
}
});
