How to concat text in Android TextView?

I want to concat two text and display with single TextView in Android. I have tried following type. It displays in logcat only, but it isn't concat in XML textview.

Here is my code:

<TextView
              android:id="@+id/heizgriffe"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="Heizgriffe"
              android:textColor="#000"
              android:textSize="12dp"
              android:textStyle="bold"

              android:layout_below="@+id/txt"/>

in Java class:

txtConcat = (TextView)findViewById(R.id.txt);
String hub="Hubraum:";
            String str= ItemList.getTxt(); // fetting from webservice
            txtConcat .setText(hub + str );

Anything wrong here?

What you intend to do is not as complicated as you see, it is true that the result you are getting is not what you want, looking at your code I can say that not even the program should compile because it must be generating a syntax error. This is because you cannot concatenate the text using setText. The solution can be the following.

XML file:

<TextView
android:id="@+id/tvInfo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="TextView" />

Java Class:

public TextView tvInfo;
private java.lang.CharSequence ID = "8945213624";

TextView tvInfo = (TextView)findViewById(R.id.tvInfo);
tvInfo.setText("My ID number is: ");
tvInfo.append(ID);

The result is as follows:

My ID number is: 8945213624

There is nothing wrong with your code, you just have to make proper use of the elements of concatenation, in this case that I show I use append to be able to concatenate the elements.

txtConcat = (TextView)findViewById(R.id.txt);

Shouldn't it be: txtConcat = (TextView)findViewById(R.id.heizgriffe);

txtConcat = (TextView)findViewById(R.id.txt); // initialize
String hub="Hubraum:";
String str= ItemList.getTxt(); // fetching from webservice
txtConcat .setText(hub + str );
