Question

I've got a small problem.

Please help me guys! Thanks a lot of You can give me any idea of it. Cheers!

Answer 1

The problem is that your LinearLayout has a padding of 5dp, which keeps your "Invite Friends" TextView away from the edge.

Replace

<LinearLayout
        android:layout_height="150dp"
        android:orientation="vertical"
        android:padding="5dp"
        android:weightSum="1"
        android:layout_width="150dp">

with

<LinearLayout
        android:layout_height="150dp"
        android:orientation="vertical"
        android:paddingTop="5dp"
        android:paddingBottom="5dp"
        android:paddingEnd="5dp"
        android:weightSum="1"
        android:layout_width="150dp">

This way you will have no padding on the left. To compensate it on the description text, add android:paddingStart="5dp" to your TextView txtdesc

Answer 2

Although im fairly new to Android Studio, i'd recommend you to try changing the layout gravity property on that specific TextView to adjust itself to the left corner and/or try forcing a padding to the left aswell.

Though this is just a guess of what could solve it, i hope it helps

Answer 3

将该视图的布局重力设置为android:layout_gravity="left"

solution:--- Please add following property within name textview . android:gravity="center_horizontal"

your code:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

    android:layout_centerVertical="true"
    android:gravity="center"
    android:paddingBottom="10dp"
    android:paddingTop="10dp">

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"

            android:textSize="12sp"
            android:visibility="gone" />
    </LinearLayout>

    <LinearLayout

            android:textAllCaps="false"
            android:textSize="18sp"
            android:textStyle="normal|bold" />

            android:text="This is a description of the offer and this is just a demo to show off 3 lines stacking correctly on top of each other"
            android:textColor="#80869c" />
    </LinearLayout>

    <ImageView
        android:id="@+id/nextArrow"
        android:layout_width="32dp"
        android:layout_height="32dp"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_gravity="center"
        android:layout_marginRight="16dp"
        android:contentDescription="@string/app_name"
        android:rotation="180"
        android:visibility="gone" />

</LinearLayout>

Answer 5

The padding attribute for the linear layout encompassing the text and image view should be set to 0.

android:padding="5dp"

This includes paddings left & right, hence the purple colour has a slight gap, remove the padding and the purple shape will reach the sides of the container shape.

I noticed you only want the purple shape to touch the RHS, hence we only want to remove the paddingLeft.

  android:paddingRight="5dp"
  android:paddingLeft="0dp"
  android:paddingBottom="5dp"
  android:paddingTop="5dp"

The TextView's gravity attribute must then be set to 'left'

  android:gravity="left"
