java - Android - Center Textview in ImageView of Relative Layout -

-

i have relative layout imageview in , want center textview in side imageview, in activity layout xml file.

here image view , have tried textview

this inside of relative layout:

<imageview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:minheight="170dp"     android:minwidth="170dp"     android:id="@+id/logobackground"     android:layout_alignparenttop="true"     android:layout_alignparentleft="true"     android:layout_alignparentstart="true"     android:layout_marginleft="33dp"     android:layout_marginstart="33dp"     android:layout_margintop="33dp"     android:contentdescription="@string/content_description_useless"     android:background="#ffffd0cd" />  <textview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="@string/capital_u"     android:id="@+id/textview"     android:textsize="30sp"     android:layout_aligntop="@+id/logobackground"     android:layout_alignleft="@+id/logobackground"     android:layout_alignstart="@+id/logobackground"     android:layout_marginleft="43dp"     android:layout_marginstart="43dp"     android:layout_margintop="65dp"/>

it looks okay think margintop 65 shouldn't half of height of imageview?

thanks in advance.

it's not working because you're telling textview in center of parent relativelayout, imageview attached top-left of parent.

one approach force textview exact size of imageview using relativelayout's alignxyz properties. set gravity attribute center, , makes text appear in center of textview's bounds. should work long imageview larger textview in dimensions.

<textview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="@string/capital_u"     android:id="@+id/textview"     android:textsize="30sp"     android:layout_aligntop="@+id/logobackground"     android:layout_alignleft="@+id/logobackground"     android:layout_alignright="@+id/logobackground"     android:layout_alignbottom="@+id/logobackground"     android:gravity="center"/>

will work you?

i'm combining 3d content three.js html , svg content. three.js cssloader pretty job synchronizing placement of html , svg content in 3d world. but svg/html coordinate systems 'left-handed', whereas three.js coordinate system 'right-handed'. means y-axes reversed. in svg/html, y / top goes go down screen, , three.js uses more standard mathematical convention of y going down go down screen. i have continually convert 1 other, pretty error prone. know not first run (for example, look here ). has come general solution? here's tried: do in object3d .scale.y = -1 . may suspect, turns out disaster. turns inside-out, , don't try put camera in there. do in object3d .rotate.x = math.pi . more promising, z axis no longer consistent html concept of z-index. still, i'm using now. in html, don't use top , use bottom . in svg , inside <g transform="scale(1, -1)"> inside <g transform="translate(0, imageheight)"> . h...
