android-relativelayout

问题 I'm trying to migrate from RelativeLayout to ConstraintLayout but I'm having problems adding the AdMob AdView to the bottom and the rest of the content above it. For example, using RelativeLayout was that simple. You only need to put android:layout_alignParentBottom="true" on the AdView and android:layout_above="@+id/adView" on the view which is containing the stuff. I'm trying to understand how to migrate this sample code and these two lines of code to the equivalent using a ConstraintLayout

问题 I need to place a TextView above the Button in RelativeLayout. But it is not working: TextView is always under the Button, even if I move it before the button. I also tried bringChildToFront() function to move textview on front, but no luck. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/rlBottom" android:layout_width="fill_parent" android:layout_height="match_parent"> <Button android:id="@+id/bVio" android:layout_width="wrap_content" android

What am I missing? public void onCreate(Bundle savedInstanceState) { super

问题 I've seen this subject about puting a border around an android textview, and I used it. But now, I would like to put a border around widgets which are situated into a relative layout. How can I do it? 回答1: in your res/drawable folder, create a new file background_border.xml In this file, you will define the background for widget like this: <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" > <!-- This is the stroke you want to define --> <stroke

问题 I have an ImageView and have set its layout_height to "100dp" and its layout_width to "wrap_content". The drawable used has bigger actual dimensions that are 130dp (width) X 215dp (height). When the ImageView is placed inside a LinearLayout , if I set adjustViewBounds to true, it gets a width that is measured according to the drawable's aspect ratio and the layout_width. However, when placed inside a RelativeLayout the ImageView gets the same width as the drawable (130dp), no matter the
