Add a Textview to a FrameLayout in a determined position

Question

I'm trying to add a textView to a frameLayout. The TextView has wrap_content properties, so it grows when the text grows. I'm adding it to a FrameLayout with this function:

((FrameLayout) findViewById(R.id.mainLayout)).addView(mEditText);

This is the xml of the frame layout:

<FrameLayout  
xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/mainLayout"
android:layout_width="wrap_content"  
android:layout_height="wrap_content"> 
</FrameLayout>

The textView always appears in the top left corner of the screen. I'd like to position it in the middle, or top middle. How can this be done?
I looked over the answers in How can I dynamically set the position of view in Android? and they weren't much help :( Mainly caused crashes..

Try this:

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, Gravity.CENTER);

((FrameLayout) findViewById(R.id.mainLayout)).addView(mEditText, params);

Change Gravity to suit your need.

BTW, the frame layout should use fill_parent for width and height

Thanks, this is the only thing that worked!! Changing the frame layout to fill_parent ruins stuff for me, it doesn't show the views that are under this view. – n00b programmer Jun 18 '12 at 16:06
instead of fill_parent better to use match_parent. – drdrej May 01 '14 at 18:09
You might also use `LayoutParams.WRAP_CONTENT` for `width` property in case your textview has a small text. – Nelson Almendra Apr 05 '17 at 17:08

Try to gravity or Layout gravity to your Framelayout or the Textview. It makes your Layout to the center of the screen. Use like this,

android:layout_gravity="center"

or

android:gravity="center"

you can try it by set the gravity of text use it like-

textview.setGravity(Gravity.center);

othervise by xml set gravity to center so it will display you in center and if you'll use centerinparents so it will always apperas at the center of screen.

Doesn't work. The view still appears at the top left, but the cursor is now in the middle of the view – n00b programmer Jun 18 '12 at 15:44

Set FrameLayout properties android:layout_width and android:layout_height to fill_parent and also set TextView property LayoutGravity . such as Center, Right or Top.

Thanks

Add android:layout_gravity="center" in your frame layout

<FrameLayout  
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/mainLayout"
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"
    android:layout_gravity="center" > 
</FrameLayout>

Setting the gravity programatically definitely works Please set the layout_gravity to right in the xml TextView.setGravity(Gravity.RIGHT);
