First Create a Button in your XML file.(activity_main.xml)

 <Button

                        android:id="@+id/show_alert"

                          android:layout_width="wrap_content"

                           android:layout_height="wrap_content"

                            android:text="Show Alert"

                             android:textSize="@dimen/text_size" />

Code for alert Dialog box 

MainActvity.java

.......................
...........................
Button showAlert=(Button) findViewById(R.id.show_alert);
holder.showAlert.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                AlertDialog.Builder builder1 = new AlertDialog.Builder(mContext);

                builder1.setMessage("Hello I'm Alert Box");

                builder1.setPositiveButton("Yes", new DialogInterface.OnClickListener() {

                    public void onClick(DialogInterface dialog, int ids) {

                        if (Utils.isNetworkAvailable(mContext)) {

                          ...............

                          ....................// Write Your Code here

                           .......................

                        } else {

                            Toast.makeText(mContext, mContext.getString(R.string.no_internet), Toast.LENGTH_SHORT).show();

                        }

                    }

                });

                builder1.setNegativeButton("No", new DialogInterface.OnClickListener() {

                    public void onClick(DialogInterface dialog, int id) {

                        dialog.cancel();

                    }

                });

                builder1.show();

            }

        });
