Question

I am trying to implement a android app. I have problems with TextView in a ScrollView. When I write some text into TextView according to its lenght some rows of the text at the top cannot be seen. I think they are occuluded with other things which resides in the top. Here is my xml file.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<RadioGroup
    android:id="@+id/RadioGroup1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <RadioButton
        android:id="@+id/SayisalRadioButton"
        android:layout_width="158dp"
        android:layout_height="wrap_content"
        android:checked="true"
        android:text="@string/SayisalLoto" />

    <RadioButton
        android:id="@+id/SuperLotoRadioButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/SuperLoto" />

</RadioGroup>

<TableRow
    android:id="@+id/KolonSayisiTableRow"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <EditText
        android:id="@+id/KolonSayisiEditText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:hint="@string/KolonSayisiHint"
        android:inputType="number"
        android:text="@string/Bos" >

        <requestFocus />
    </EditText>

    <Button
        android:id="@+id/SallaButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/Uret" />

    <ProgressBar
        android:id="@+id/SonucProgressBar"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="150dp"
        android:layout_height="wrap_content"
        android:visibility="invisible" />

</TableRow>

<ScrollView
    android:id="@+id/SonucScrollView"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="center" >
    <TextView
        android:id="@+id/SonucTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:editable="false"
        android:scrollbarAlwaysDrawVerticalTrack="true"
        android:text="@string/Bos"
        android:textAppearance="?android:attr/textAppearanceMedium" />

</ScrollView>

</LinearLayout>

For Example when I put a text with multiple lines into the TextView with ID : SonucTextView according to its size I cannot see the some parts of the text at the top. How can I solve this problem? Is it related to the layout that I am using?

Answer 1

Your question is related to this one. So I suggest you check out the accepted answer.

That answer states that all you have to do is to set the maximum lines you want it to display and give it a scrollbar like so:

<TextView
    android:id="@+id/SonucTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"     
    android:editable="false"    
    android:text="@string/Bos"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:maxLines="5"
    android:scrollbars="vertical" />

And then proceed to setting the event in the code :

TexView.setMovementMethod(new ScrollingMovementMethod())

I’d like to add that the ScrollView widget is to be used when you want your entire view to scroll, not a single widget.

Hope this helps!
