Question

我需要在TextView内创建类似滚动ScrollView ...就像可滚动ScrollView内的1个主TextView我已将此代码放入RelativeLayout

  <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/img_view_flag"
        android:layout_marginTop="17dp" 
        android:paddingBottom="20dip">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical" >



                <TextView
                    android:id="@+id/tv_desc"
                    android:layout_width="wrap_content"

        </LinearLayout>
    </ScrollView>

但不适合我.... 主滚动条工作

Answer 1

这个问题有点复杂，我没有足够的时间来解释，但你可以通过在onCreat类或onCreatView类的末尾添加这些onTouch类来轻松摆脱它（如果你使用的是片段）。

scrollview1.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                tv_desc.getParent().requestDisallowInterceptTouchEvent(false);

                return false;
            }
        });

tv_desc.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                tv_desc.getParent().requestDisallowInterceptTouchEvent(true);

                return false;
            }
        });

以及其他文字视图。

Answer 2

只需设置

即可

android:maxLines = "AN_INTEGER"

android:scrollbars = "vertical"

布局的xml文件中TextView的属性。

然后使用：

tv_desc.setMovementMethod(new ScrollingMovementMethod());


scrollview.setOnTouchListener(new OnTouchListener() { 

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            tv_desc.getParent().requestDisallowInterceptTouchEvent(false);

            return false;
        }
    });

tv_desc.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            tv_desc.getParent().requestDisallowInterceptTouchEvent(true);

            return false;
        }
    });

希望它能运作

Answer 3

实际上，使TextView / EditText在ScrollView中滚动的唯一方法（对我有用）是

public class Utils {
    public static void enableScroll(View view) {
        if (view instanceof TextView) {
            TextView textView = (TextView) view;
            textView.setMovementMethod(new ScrollingMovementMethod());
        }

        view.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                v.getParent().requestDisallowInterceptTouchEvent(true);
                switch (event.getAction() & MotionEvent.ACTION_MASK) {
                    case MotionEvent.ACTION_UP:
                        v.getParent().requestDisallowInterceptTouchEvent(false);
                        break;
                }
                return false;
            }
        });
    }
}

使用

<TextView
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:scrollbars="vertical" />

（无需设置android:maxLines属性）

使用

TextView textView = findViewById(R.id.textView);
Utils.enableScroll(textView);

Answer 4

您还可以简单地向textView添加一点高程。

    <TextView
        android:id="@+id/tv_composer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:elevation="1dp"
        android:layout_below="@+id/textView3"
        android:text="Small Text"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:textColor="@color/black" />

这对我有用。：）

Answer 5

首先，设置android:scrollbars="vertical"：

<AppCompatTextView
    android:id="@+id/actv"
    ...
    android:scrollbars="vertical" />

此外，添加此扩展功能：

/**
 * If this [AppCompatTextView] is placed inside ScrollView then we allow it get scrolled inside
 * that ScrollView
 */
fun AppCompatTextView.makeScrollableInsideScrollView() {
    movementMethod = ScrollingMovementMethod()
    setOnTouchListener { v, event ->
        v.parent.requestDisallowInterceptTouchEvent(true)
        when (event.action and MotionEvent.ACTION_MASK) {
            MotionEvent.ACTION_UP -> {
                v.parent.requestDisallowInterceptTouchEvent(false)
                //It is required to call performClick() in onTouch event.
                performClick()
            }
        }
        false
    }

然后致电：

actv.makeScrollableInsideScrollView()

在scrollview里面的android可滚动textview
