String concatenate is not working in Android Linear layout

Question

I need to concatenate two string and display with single text view. That string concatenate is working fine within Relative Layout. But i want to concatenate within Linear layout.

Here my code:

<LinearLayout 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/l1"
    android:id="@+id/ll"
    android:orientation="vertical"
>
    <TextView
        android:id="@+id/hubraum"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="8dp" 
        android:text="Hubraum :"
        android:textColor="#000"
        android:textSize="12dp" 
        android:layout_gravity="left"
    />
</LinearLayout>

.java

String title  = "Hubraum: ";
String value  = bikeItemList.getHubraum();
String result = title + value;          
txtCapacity.setText(result);

I tried the above type and following type also

txtCapacity.setText("Hubraum: " +","+ bikeItemList.getHubraum());

But it only display bikeItemList.getHubraum(). the "Hubraum:" is not display.

I tried with using append also but it display bikeItemList.getHubraum() this text only.

Any one can know the reason.

what is bikeItemList? Is it List? getHubraum returns what type? Please specify this things — Scorpion

StringBuilder b = new StringBuilder(128);

b.append(title).append(value);

b.toString();

Please try following way,

String str = "Hubraum: " +","+ bikeItemList.getHubraum().toString();
txtCapacity.setText(str);

Just use append properties of tectview for only value bcz title is already you have given in xml

    String title="Hubraum: ";
    String value = bikeItemList.getHubraum().toString();
    txtCapacity.append(value);

Check to see if it is called from the UIThread, also you can try

txtCapacity.invalidate();

to force a refresh/redraw.

There's also a chance that your Java code is not called at all, try change the default text from

android:text="Hubraum :"

to something else, and see if it's the default text that's being shown.

You can also use StringBuffer and append the string. display txtCapacity.setText(strbuf.toString());
