Android TextView text won't center

I am trying to make a PIN entry activity, but one little thing is not quite working for me. I can't get the text to center in the TextView's at the top of the screenshot here: The way it will work is when the user is entering a PIN, I will place a star in each TextView for visible feedback. The problem is, I want the star to be centered. I have tried layout_gravity="center", but it doesn't make a difference. Here's my current layout: ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:textAppearance="?android:attr/textAppearanceLarge" android:layout_height="wrap_content" android:id="@+id/textView1" android:text="PIN Required" android:layout_width="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginBottom="12sp" ></TextView> <LinearLayout android:layout_width="match_parent" android:id="@+id/linearLayout1" android:layout_height="wrap_content" android:layout_marginBottom="12sp" android:layout_gravity="center_horizontal" > <TextView android:id="@+id/text1" android:layout_height="32sp" android:layout_width="48sp" android:layout_weight="1" android:layout_marginRight="2sp" android:layout_marginLeft="48sp" android:background="#FFFFFF" android:text="X" android:layout_gravity="center" ></TextView> <TextView android:id="@+id/text2" android:layout_height="32sp" android:layout_width="48sp" android:layout_weight="1" android:layout_marginRight="2sp" android:layout_marginLeft="2sp" android:background="#FFFFFF" ></TextView> <TextView android:id="@+id/text3" android:layout_height="32sp" android:layout_width="48sp" android:layout_weight="1" android:layout_marginRight="2sp" android:layout_marginLeft="2sp" android:background="#FFFFFF" ></TextView> <TextView android:id="@+id/text4" android:layout_height="32sp" android:layout_width="48sp" android:layout_weight="1" android:layout_marginRight="48sp" android:layout_marginLeft="2sp" android:background="#FFFFFF" ></TextView> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:id="@+id/linearLayout2" android:layout_height="wrap_content" android:layout_marginBottom="12sp" > <Button android:text="1" android:textColor="#FFFFFF" android:id="@+id/button1" android:layout_height="32sp" android:layout_width="64sp" android:layout_weight="1" android:editable="false" android:layout_marginRight="2sp" android:layout_marginLeft="48sp" android:background="@drawable/action_background_gradient" android:onClick="ButtonClicked" ></Button> <Button android:text="2" android:textColor="#FFFFFF" android:id="@+id/button2" android:layout_height="32sp" android:layout_width="64sp" android:layout_weight="1" android:editable="false" android:layout_marginRight="2sp" android:layout_marginLeft="2sp" android:background="@drawable/action_background_gradient" android:onClick="ButtonClicked" ></Button> <Button android:text="3" android:textColor="#FFFFFF" android:id="@+id/button3" android:layout_height="32sp" android:layout_width="64sp" android:layout_weight="1" android:editable="false" android:layout_marginRight="48sp" android:layout_marginLeft="2sp" android:background="@drawable/action_background_gradient" android:onClick="ButtonClicked" ></Button> </LinearLayout> <!--... and so on for the rest of the buttons ... --> </LinearLayout> ``` I've got that android:text="X" in there for the first textview just so I can see if it is working. When I am done tweaking the layout, that will go away. What simple thing am I missing?
