Question

我尝试使用带有textView的scrollView但它运行不顺畅。在代码中，我要滚动的textView是“writeCodeTV”

activity_program.xml

writeCodeTV.setMovementMethod(new ScrollingMovementMethod())

还将textMovementMethod用于TextView

ProgramActivity.java

我可能做错了什么？

我稍微更改了布局并且工作正常，我将父级从scrollView更改为HorizontalScrollVIew并且它工作正常。

<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"
    />

TextView不能平滑滚动
