You can’t increment alphanumeric values directly. if want to do so you need to write some lines of code for it
here is activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:orientation="vertical">
<TextView
android:id="@+id/txt_autoincreament"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="click"
android:onClick="Click"/>
</LinearLayout>
here is MainActivity.java
public class MainActivity extends AppCompatActivity {
TextView autoTextIncreament;
String stringValue="ABB";
long intValue=20180001;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
autoTextIncreament = findViewById(R.id.txt_autoincreament);
}
public void Click(View view){
autoTextIncreament.setText(getValue());
}
private String getValue() {
return stringValue+String.valueOf(intValue++);
}
}
hope this will help you.
