Question

I am trying to set gravity of the text view through java in the following way

if(check.equals("left")){           
        results.setGravity(Gravity.LEFT);           
    } else if(check.equals("center")){
        results.setGravity(Gravity.CENTER);
    } else if(check.equals("right")){
        results.setGravity(Gravity.RIGHT);
    }

But this does not work correctly.
and in XML file the gravity is pre-set to center.

Here the results is TextView type variable .

this is the parent XML code:

<TextView android:id="@+id/textView1" 
 android:layout_width="fill_parent" 
 android:layout_height="wrap_content" 
 android:gravity="center" 
 android:text="Text" android:textSize="30dp" />

Please help me

And whole Layout XML code is

<EditText
    android:id="@+id/etCommands"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="Type some commands"
    android:inputType="textPassword" >

</EditText>

   <LinearLayout 
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:orientation="horizontal"
       android:weightSum="100"
       >

<Button
    android:onClick="cmdClick"
    android:layout_weight="20"
    android:id="@+id/bResults"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textSize="30dp"
    android:text="Try Commond" />

<ToggleButton
    android:id="@+id/tgPassword"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:layout_weight="80"
    android:checked="true"
    android:paddingBottom="20dp"
    android:text="ToggleButton"
    android:onClick="togClick"
     />

 </LinearLayout>


    <TextView
       android:id="@+id/textView1"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"           
       android:gravity="center"
       android:text="Text" 
       android:textSize="30dp"
       />

Answer 1

Use a RelativeLayout, and in your TextView XML set
android:layout_centerVertical="true" android:layout_centerHorizontal="true"

Depending on your other code, try doing:

textView.setLayoutParams(new LayoutParams(Layout.CENTER_HORIZONTAL, Gravity.CENTER_VERTICAL));
