Mixing increase/decrease buttons with Edit Text (numbers)

Question

I have an online android app store and when a user tries to enter a large amount of Quantity he should keep clicking on increase buttons, (you can imagine how hard its if he wants to enter 100 items). So to resolve it I'm trying to add EditText to the increase and decrease buttons, the increase/decrease buttons work well. The problem is: When I enter a value by typing a quantity using EtideText, the value won't pass to the next activity

Layout:

                <LinearLayout
                android:id="@+id/ll_controller"
                android:layout_width="60dp"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:layout_margin="@dimen/value_3"
                android:layout_marginLeft="10dp"
                android:layout_marginRight="10dp"
                android:background="@drawable/cart_round_button"
                android:gravity="center"
                android:orientation="vertical"
                android:padding="@dimen/value_3">

                <ImageView
                    android:id="@+id/tvIncrement"
                    android:layout_width="45dp"

                    app:srcCompat="@drawable/ic_plus_sign" />


                <EditText

                <ImageView

Answer 1

you should implement it to your grade file

implementation 'com.github.travijuu:numberpicker:1.0.7'

in Xml Layout file.

<com.travijuu.numberpicker.library.NumberPicker
    android:id="@+id/number_picker"
    android:layout_width="130dp"
    android:layout_height="40dp"
    numberpicker:min="0"
    numberpicker:max="10"
    numberpicker:value="-5"
    numberpicker:unit="1"
    numberpicker:focusable="false"
    numberpicker:custom_layout="@layout/number_picker_custom_layout" />   

       

in java File.

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        NumberPicker numberPicker = (NumberPicker) findViewById(R.id.number_picker);
        numberPicker.setMax(15);
        numberPicker.setMin(5);
        numberPicker.setUnit(2);
        numberPicker.setValue(10);
    }
}
