Question

In the following code:

<ScrollView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        xmlns:android="http://schemas.android.com/apk/res/android">

    <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingLeft="16dp"
            android:paddingRight="16dp"
            android:orientation="vertical">

        <TextView
                android:layout_marginTop="20dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="27sp"
                android:text="@string/create_card_text"/>

        <TextView
                android:layout_marginTop="20dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="24sp"
                android:textColor="#ff949494"
                android:text="@string/create_card_info_text_one"/>

        <EditText
                android:id="@+id/name"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="40dp"
                android:hint="Name"/>

        <EditText
                android:id="@+id/email"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="20dp"
                android:inputType="textEmailAddress"
                android:hint="Email"/>

        <TextView
                android:id="@+id/phone_number"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:textSize="20sp"
                android:layout_marginLeft="10dp"
                android:layout_marginTop="20dp"
                android:hint="Phone Number"/>

        <Button
                android:id="@+id/next_button"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginTop="20dp"
                android:layout_marginLeft="280dp"
                android:text="@string/create_card_next_button"
                android:onClick="next"/>

    </LinearLayout>

</ScrollView>

The button just does not shows up. What could be wrong?

Answer 1

Try like this.

You have set android:layout_marginLeft="280dp" so replace this with

android:layout_marginLeft="20dp" or something else

so basically your button's code will look something like this

<Button
     android:id="@+id/next_button"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_marginTop="20dp"
     android:layout_marginLeft="20dp"
     android:text="@string/create_card_next_button"
     android:onClick="next"/>

I think you have set margin left to 280dp which is causing problem and making it out of your screen set it to 20dp or as per your screen requirement as you have set other and it should work.
