TexView scrollt nicht reibungslos

Question

Ich habe versucht, scrollView mit dem textView, aber es funktioniert nicht reibungslos. In dem Code, der Textview i bewegen wollen "writeCodeTV"

activity_program.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
android:orientation="vertical" 
tools:context="com.example.abhishek.canddatastructureprograms.ProgramActivity"> 

<TextView 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:id="@+id/tV1" 
android:text="CODE" 
android:textColor="@android:color/holo_blue_dark" 
android:textStyle="bold" 
android:paddingTop="10dp" 
android:paddingBottom="10dp" /> 
<ScrollView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"> 
<HorizontalScrollView 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 

> 

<TextView 
    android:padding="5dp" 
    android:layout_width="match_parent" 
    android:layout_height="300dp" 
    android:textColor="@android:color/black" 
    android:scrollHorizontally="true" 

    android:scrollbars="vertical|horizontal" 
    android:id="@+id/writeCodeTV" 
    android:text="CODE" 
    /> 
</HorizontalScrollView> 
</ScrollView> 

<TextView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/tV2" 
    android:text="OUTPUT" 

    android:textColor="@android:color/holo_blue_dark" 
    android:textStyle="bold" 
    android:paddingBottom="10dp" 
    android:paddingTop="10dp" /> 
<TextView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:padding="5dp" 
    android:scrollbars="horizontal|vertical" 
    android:id="@+id/writeOutputTV" 
    android:textColor="@android:color/black" 
    android:text="CODE" 
    /> 
</LinearLayout> 

Auch setMovementMethod für die Textview verwendet

ProgramActivity.java

writeCodeTV.setMovementMethod(new ScrollingMovementMethod()) 

Was mache ich möglicherweise falsch?

Answer 1

Ich änderte das Layout ein bisschen und es funktionierte, änderte ich die Eltern von scrollView zu HorizontalScrollView und es funktionierte.

<TextView 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:id="@+id/tV1" 
android:text="CODE" 
android:textColor="@android:color/holo_blue_dark" 
android:textStyle="bold" 
android:paddingTop="10dp" 
android:paddingBottom="10dp" /> 
<HorizontalScrollView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"> 
<ScrollView 
    android:layout_width="fill_parent" 
    android:layout_height="300dp" 
    > 


<TextView 
    android:padding="5dp" 
    android:layout_width="fill_parent" 
    android:layout_height="300dp" 
    android:textColor="@android:color/black" 
    android:scrollHorizontally="true" 

    android:scrollbars="vertical|horizontal" 
    android:id="@+id/writeCodeTV" 
    android:text="CODE" 
    /> 

</ScrollView> 
</HorizontalScrollView> 

<TextView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/tV2" 
    android:text="OUTPUT" 

    android:textColor="@android:color/holo_blue_dark" 
    android:textStyle="bold" 
    android:paddingBottom="10dp" 
    android:paddingTop="10dp" /> 
<TextView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:padding="5dp" 
    android:scrollbars="horizontal|vertical" 
    android:id="@+id/writeOutputTV" 
    android:textColor="@android:color/black" 
    android:text="CODE" 
    />
