Android 如何在滚动视图内滚动编辑文本

How to scroll the edittext inside the scrollview

提问by Maveňツ

I have a scrollview inside which there is a editext which is multiline. I want to scroll the edittext to see the lower content but it can't be done.

我有一个滚动视图，里面有一个多行的 editext 。我想滚动编辑文本以查看较低的内容，但无法完成。

android:scrollbarStyle="insideInset"
android:scrollbars="vertical"

Example

例子

First add this at XML

首先在 XML 添加这个

android:scrollbarStyle="insideInset"
android:scrollbars="vertical" 
android:overScrollMode="always"

Then add the same above "OnTouch" but make it return "false" not "true"

然后在“OnTouch”上方添加相同的内容，但使其返回“false”而不是“true”

public boolean onTouch(View view, MotionEvent event) {

                    if (view.getId() == R.id.DwEdit) {
                        view.getParent().requestDisallowInterceptTouchEvent(true);
                        switch (event.getAction()&MotionEvent.ACTION_MASK){
                        case MotionEvent.ACTION_UP:
                            view.getParent().requestDisallowInterceptTouchEvent(false);
                            break;
                        }
                    }
                    return false;
}

you should use NestedScrollView class. This class support child scrolling inside parent scrolling. This class can be a child or a parent.

你应该使用 NestedScrollView 类。此类支持父滚动内的子滚动。这个班级可以是孩子或家长。

<android.support.v4.widget.NestedScrollView         
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#d6d8d9">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:maxLines="512"
                android:text=" your content"/>
        <android.support.v4.widget.NestedScrollView
            android:layout_below="@id/ll_button"

Building upon the answer by @Ayman Mahgoub and @Hariharan. The solution worked great except while scrolling the edit text there is no scroll momentum. As soon as the finger lifts up, the scrolling immediately stops.

基于@Ayman Mahgoub 和@Hariharan 的回答。该解决方案效果很好，除了在滚动编辑文本时没有滚动动力。手指一抬起，滚动立即停止。

To gain scroll momentum wrap a scrollview around the EditText and let the EditText's height wrap content (set minHeight if you'd like). Remove the following lines from the edit text:

为了获得滚动动力，在 EditText 周围包裹一个滚动视图，让 EditText 的高度包裹内容（如果你愿意，可以设置 minHeight）。从编辑文本中删除以下行：

android:scrollbarStyle="insideInset"
android:scrollbars="vertical" 
android:overScrollMode="always"

Now the nested ScrollView wrapped around the EditText takes care of the scrolling. Update the onTouch handler to take into account the updated view hierarchy:

现在包裹在 EditText 周围的嵌套 ScrollView 负责滚动。更新 onTouch 处理程序以考虑更新的视图层次结构：

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

Be warned, this solution is now tightly coupled to the view hierarchy.

请注意，此解决方案现在与视图层次结构紧密耦合。

I would vote up the updated answer provided by @Ayman Mahgoub, but I do not have a high enough reputation. His code works. I had to change return true to return false. You put the .setOnTouchListener() method in your java class and put the three lines:

我会投票支持@Ayman Mahgoub 提供的更新答案，但我的声誉不够高。他的代码有效。我不得不改变 return true 返回 false。您将 .setOnTouchListener() 方法放在您的 java 类中并放置三行：

android:scrollbarStyle="insideInset"
android:scrollbars="vertical" 
android:overScrollMode="always"

in the corresponding xml file. You can see the implementation in the android emulator, and on the android phone you use for testing. Thank you so much @Ayman Mahgoub and @Hariharan!

在相应的 xml 文件中。您可以在 android 模拟器和用于测试的 android 手机上查看实现。非常感谢@Ayman Mahgoub 和@Hariharan！

Below Answer will help you to make Edit Text scrollable inside Scroll View and also show Count of it.

下面的答案将帮助您使编辑文本在滚动视图内可滚动并显示它的计数。

1.Make one rectangle_with_border_gray.xml file in @drawable folder.

1.在@drawable 文件夹中制作一个 rectangle_with_border_gray.xml 文件。

 <?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="rectangle">
        <corners android:radius="0dp"/>
        <solid android:color="#FFFFFF"/>
        <stroke android:color="#7f848686"
            android:width="0.01dp"/>
    </shape>

2.Then, In @layout write below code in scroll view.

2.然后，在@layout 中在滚动视图中编写下面的代码。

First create a custom Scrollview class as given below:

首先创建一个自定义 Scrollview 类，如下所示：

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.ScrollView;

public class MyCustomScrollview extends ScrollView {

    public VerticalScrollview(Context context) {
        super(context);
    }

    public VerticalScrollview(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public VerticalScrollview(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        final int action = ev.getAction();
        switch (action)
        {
            case MotionEvent.ACTION_DOWN:
                Log.i("VerticalScrollview", "onInterceptTouchEvent: DOWN super false" );
                super.onTouchEvent(ev);
                break;

            case MotionEvent.ACTION_MOVE:
                return false; // redirect MotionEvents to ourself

            case MotionEvent.ACTION_CANCEL:
                Log.i("VerticalScrollview", "onInterceptTouchEvent: CANCEL super false" );
                super.onTouchEvent(ev);
                break;

            case MotionEvent.ACTION_UP:
                Log.i("VerticalScrollview", "onInterceptTouchEvent: UP super false" );
                return false;

            default: Log.i("VerticalScrollview", "onInterceptTouchEvent: " + action ); break;
        }

        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        super.onTouchEvent(ev);
        Log.i("VerticalScrollview", "onTouchEvent. action: " + ev.getAction() );
        return true;
    }
}

1. Now in the activity or fragment where you are using the EditText, write the following code for the EditText object that you want to scroll inside the Scrollview :

   import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.MotionEvent; import android.view.View; import android.widget.EditText;

   public class MainActivity extends AppCompatActivity {

   EditText et;
   VerticalScrollview sv;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
   
       init();
   }
   
   private void init() {
       sv = findViewById(R.id.sv);
       et = findViewById(R.id.et);
       et.setOnTouchListener(new View.OnTouchListener() {
           @Override
           public boolean onTouch(View v, MotionEvent event) {
               if (v.getId() == R.id.sv) {
                   v.getParent().requestDisallowInterceptTouchEvent(true);
                   switch (event.getAction() & MotionEvent.ACTION_MASK) {
                       case MotionEvent.ACTION_UP:
                           v.getParent().requestDisallowInterceptTouchEvent(false);
                           break;
                   }
               }
               return false;
           }
       });
   }
   

   }

2. 现在，在您使用 EditText 的活动或片段中，为要在 Scrollview 内滚动的 EditText 对象编写以下代码：

   导入 android.support.v7.app.AppCompatActivity; 导入 android.os.Bundle; 导入 android.view.MotionEvent; 导入 android.view.View; 导入 android.widget.EditText;

   公共类 MainActivity 扩展 AppCompatActivity {

   EditText et;
   VerticalScrollview sv;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
   
       init();
   }
   
   private void init() {
       sv = findViewById(R.id.sv);
       et = findViewById(R.id.et);
       et.setOnTouchListener(new View.OnTouchListener() {
           @Override
           public boolean onTouch(View v, MotionEvent event) {
               if (v.getId() == R.id.sv) {
                   v.getParent().requestDisallowInterceptTouchEvent(true);
                   switch (event.getAction() & MotionEvent.ACTION_MASK) {
                       case MotionEvent.ACTION_UP:
                           v.getParent().requestDisallowInterceptTouchEvent(false);
                           break;
                   }
               }
               return false;
           }
       });
   }
   

   }

3.The follwing xml is given below:

3.下面的xml如下：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <com.example.ayan.scrollableedittext.VerticalScrollview
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/sv">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="600dp"
                android:gravity="center">
                <EditText
                    android:id="@+id/et"
                    android:layout_width="200dp"
                    android:layout_height="80dp"
                    android:nestedScrollingEnabled="true"
                    android:gravity="start" />
            </LinearLayout>
        </LinearLayout>
    </com.example.ayan.scrollableedittext.VerticalScrollview>

</LinearLayout>

This will scroll the EditTextand make it editable:

这将滚动EditText并使其可编辑：

First in the XML file, add this:

首先在 XML 文件中，添加以下内容：

android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"

Then in the Java file, add this:

然后在 Java 文件中添加：

EditText.setOnTouchListener(new View.OnTouchListener() {
       @Override
       public boolean onTouch(View view, MotionEvent motionEvent) {
           view.getParent().requestDisallowInterceptTouchEvent(true);
           switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
               case MotionEvent.ACTION_SCROLL:
                  view.getParent().requestDisallowInterceptTouchEvent(false);
                   return true;
               case MotionEvent.ACTION_BUTTON_PRESS:
                   InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                   imm.showSoftInput(EditText, InputMethodManager.SHOW_IMPLICIT);
           }
           return false;
       }
});
