How to dismiss AlertDialog.Builder?

What didn't work about dismiss()?

You should be able to use either Dialog.dismiss(), or Dialog.cancel()

alertDialog.setNeutralButton("Cancel", new DialogInterface.OnClickListener() { // define the 'Cancel' button    public void onClick(DialogInterface dialog, int which) {        //Either of the following two lines should work.        dialog.cancel();        //dialog.dismiss();    } });

With the following code you can show a ListBox AlertDialog and when you press on a item you dismiss the Dialog. The order of code is importan.

AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext);String names[] ={"A","B","C","D"};ArrayAdapter<String> adapter = new ArrayAdapter<String>(mContext,android.R.layout.simple_list_item_1,names);LayoutInflater inflater = getLayoutInflater();View convertView = (View)inflater.inflate(R.layout.list_layout, null);ListView lv = (ListView) convertView.findViewById(R.id.listView1);lv.setAdapter(adapter);alertDialog.setView(convertView);alertDialog.setTitle("List");final AlertDialog ad = alertDialog.show();lv.setOnItemClickListener(new AdapterView.OnItemClickListener(){    @Override    public void onItemClick(AdapterView<?> parent, View view, int position, long id)    {        //Toast.makeText(mContext, position, Toast.LENGTH_LONG).show();        ad.dismiss();    }});

The code is very simple:

final AlertDialog show = alertDialog.show();

finally in the action of button for example:

show.dismiss();

For example with a custom alertdialog:

Code on java, you could create a Object AlertDialog:

public class ViewAlertRating {    Context context;    public ViewAlertRating(Context context) {        this.context = context;    }    public void showAlert(){        AlertDialog.Builder alertDialog = new AlertDialog.Builder(context);        LayoutInflater inflater = ((Activity) context).getLayoutInflater();        View alertView = inflater.inflate(R.layout.layout_test, null);        alertDialog.setView(alertView);        final AlertDialog show = alertDialog.show();        Button alertButton = (Button) alertView.findViewById(R.id.btn_test);        alertButton.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                show.dismiss();            }        });    }}

Code XML layout_test.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="match_parent"    android:layout_height="wrap_content">    <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="Valoración"        android:id="@+id/text_test1"        android:textSize="20sp"        android:textColor="#ffffffff"        android:layout_centerHorizontal="true"        android:gravity="center_horizontal"        android:textStyle="bold"        android:paddingTop="10dp"        android:paddingBottom="10dp"        android:background="#ff37dabb"        android:paddingLeft="20dp"        android:paddingRight="20dp" />    <LinearLayout        android:orientation="vertical"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:paddingLeft="20dp"        android:paddingRight="20dp"        android:layout_marginTop="15dp">        <EditText            android:layout_width="match_parent"            android:layout_height="120dp"            android:id="@+id/edit_test"            android:hint="Descripción"            android:textColor="#aa000000"            android:paddingLeft="10dp"            android:paddingRight="10dp"            android:textColorHint="#aa72777a"            android:gravity="top" />    </LinearLayout>    <LinearLayout        android:orientation="horizontal"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:gravity="center_horizontal"        android:paddingTop="10dp"        android:paddingLeft="15dp"        android:paddingRight="15dp"        android:paddingBottom="15dp" >        <LinearLayout            android:orientation="horizontal"            android:layout_width="match_parent"            android:layout_height="match_parent" >            <LinearLayout                android:orientation="horizontal"                android:layout_width="match_parent"                android:layout_height="match_parent"                android:weightSum="1.00"                android:gravity="right" >                <Button                    android:layout_width="match_parent"                    android:layout_height="wrap_content"                    android:text="Enviar"                    android:id="@+id/btn_test"                    android:gravity="center_vertical|center_horizontal"                    android:textColor="#ffffffff"                    android:background="@drawable/btn_flat_blue_selector" />            </LinearLayout>        </LinearLayout>    </LinearLayout></LinearLayout>

finally, call on Activity:

ViewAlertRating alertRating = new ViewAlertRating(this);alertRating.showAlert();
