How to add a check box to an alert dialog
Currently when the user opens my app, an AlertDialog
opens, asking them if they would like to upgrade to the pro version.
I need to add a CheckBox
to the AlertDialog
that will make the app no longer show the AlertDialog
when the user opens the app.
Here is what I have for the AlertDialog
now:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(" MY_TEXT");
builder.setMessage(" MY_TEXT ")
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Uri uri = Uri.parse("market://details?id=MY_APP_PACKAGE");
Intent intent = new Intent (Intent.ACTION_VIEW, uri);
startActivity(intent); }
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
}).show();
How do I add a CheckBox
to the AlertDialog
that will make the app no longer show the AlertDialog
when the user opens the app?
Solution 1:
You have to use the method setView(View)
on the AlertDialog.Builder
object. This will put the passed in View
between the message area and buttons. Simply inflate a View
with a CheckBox
and pass that in. Here's an example:
checkbox.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<CheckBox
android:id="@+id/checkbox"
style="?android:attr/textAppearanceMedium"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp" />
</FrameLayout>
Code in your Activity
View checkBoxView = View.inflate(this, R.layout.checkbox, null);
CheckBox checkBox = (CheckBox) checkBoxView.findViewById(R.id.checkbox);
checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// Save to shared preferences
}
});
checkBox.setText("Text to the right of the check box.");
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(" MY_TEXT");
builder.setMessage(" MY_TEXT ")
.setView(checkBoxView)
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Uri uri = Uri.parse("market://details?id=MY_APP_PACKAGE");
Intent intent = new Intent (Intent.ACTION_VIEW, uri);
startActivity(intent); }
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
}).show();
Solution 2:
The way to make a checkbox list is to use setMultiChoiceItems
in the AlertDialog
.
// Set up the alert builder
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Choose some animals");
// Add a checkbox list
String[] animals = {"horse", "cow", "camel", "sheep", "goat"};
boolean[] checkedItems = {true, false, false, true, false};
builder.setMultiChoiceItems(animals, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
// The user checked or unchecked a box
}
});
// Add OK and Cancel buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// The user clicked OK
}
});
builder.setNegativeButton("Cancel", null);
// Create and show the alert dialog
AlertDialog dialog = builder.create();
dialog.show();
Here I hard coded which items in the list were already checked. It is more likely that you would want to keep track of them in an ArrayList<Integer>
. See the documentation example for more details. You can also set the checked items to null
if you always want everything to start unchecked.
For context
, you can use this
if you are in an Activity.
My fuller answer is here.
Kotlin version
// Set up the alert builder
val builder = AlertDialog.Builder(context)
builder.setTitle("Choose some animals")
// Add a checkbox list
val animals = arrayOf("horse", "cow", "camel", "sheep", "goat")
val checkedItems = booleanArrayOf(true, false, false, true, false)
builder.setMultiChoiceItems(animals, checkedItems) { dialog, which, isChecked ->
// The user checked or unchecked a box
}
// Add OK and Cancel buttons
builder.setPositiveButton("OK") { dialog, which ->
// The user clicked OK
}
builder.setNegativeButton("Cancel", null)
// Create and show the alert dialog
val dialog = builder.create()
dialog.show()
