软键盘隐藏多行 EditText 下方的按钮？

Question

我有一个 RelativeLayout 和一个 EditText 下面有一个 Button。理想情况下，当用户单击 EditText 并填写多行文本时，RelativeLayout 也会随着行数的增加而扩展。然而，我现在的行为是，在 EditText 的第一行被填充后，键盘开始覆盖它下面的 Button 和 [=15= 中的 3-4 行文本之后]，Button 消失在键盘下方。有什么办法可以让它在我输入文本时，整个布局的大小增加，以便按钮保持在键盘上方？这是我的代码：

AndroidManifest.xml:

    <activity
        android:name="<Name of project>.activity.Comments"
        android:configChanges="orientation|keyboardHidden"
        android:label="Comments"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme.NoActionBar"
        android:windowSoftInputMode="stateHidden|adjustResize" />

Comments.xml:

<RelativeLayout
        android:id="@+id/send_message"
        android:layout_width="match_parent"
        android:layout_height="90dp"
        android:layout_margin="4dp"
        android:layout_alignParentBottom="true">

        <EditText
            android:fontFamily="sans-serif"
            android:id="@+id/write_comment"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="12dp"
            android:gravity="left"
            android:textSize="16sp"
            android:textColor="@color/black"
            android:cursorVisible="false"
            android:textColorHint="@color/material_color_grey_300"
            android:hint="@string/commentBack"
            android:background="@drawable/edittext_bg"
            android:inputType="textMultiLine"
            android:isScrollContainer="true"
            android:maxLength="200"
            android:scrollHorizontally="false" />

        <Button
            android:fontFamily="sans-serif-medium"
            android:id="@+id/send_comment"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="16sp"
            android:textColor="@color/colorPrimary"
            android:layout_marginTop="8dp"
            android:text="@string/send"
            android:background="@null"
            android:layout_below="@id/write_comment"
            android:layout_alignParentRight="true"
            android:layout_alignParentBottom="true"
            android:textAllCaps="false" />
    </RelativeLayout>

我试图添加 android:isScrollContainer="true"，认为它会在 EditText 中创建一个滚动容器，这样它会帮助扩展布局，但似乎没有用。任何帮助，将不胜感激。谢谢！

编辑：应 Jaydroider 的要求，我附上了一张照片来说明我的问题。如果我可以制作 GIF 或其他东西，如果我向我的 EditText 字段添加更多文本，Send 按钮将在键盘下方消失，除非我从 EditText 中删除文本，`无法推送发送：

编辑：如果有帮助，我还展示了当我单击此处的 EditText 时如何滚动到 ListView 的底部。

public void setupComment(final EditText comment) {
        //Once we send the post, we want to scroll to bottom of listview
        comment.setOnEditorActionListener(new TextView.OnEditorActionListener() {

            @Override
            public boolean onEditorAction(TextView v, int actionId,
                                          KeyEvent event) {
                if (event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
                    comment.setImeOptions(EditorInfo.IME_ACTION_DONE);
                    resetKeyboardSettings();
                }
                return false;
            }
        });

        //Hide the cursor until view is clicked on
        View.OnTouchListener onTouchListener = new View.OnTouchListener(){
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                System.out.println("Touched");
                if (v.getId() == comment.getId()) {
                    comment.setCursorVisible(true);
                }
                commentsView.postDelayed(new Runnable() {
                    @Override
                    public void run() {

                        commentsView.smoothScrollToPosition(commentsView.getAdapter().getCount());
                    }
                }, 750);
                return false;
            }
        };
        comment.setOnTouchListener(onTouchListener);
    }

试试这个：

<RelativeLayout
        android:id="@+id/send_message"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="4dp"
        android:layout_alignParentBottom="true">

        <EditText
            android:fontFamily="sans-serif"
            android:id="@+id/write_comment"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="12dp"
            android:gravity="left"
            android:textSize="16sp"
            android:textColor="@color/black"
            android:cursorVisible="false"
            android:textColorHint="@color/material_color_grey_300"
            android:hint="@string/commentBack"
            android:background="@drawable/edittext_bg"
            android:inputType="textMultiLine"
            android:isScrollContainer="true"
            android:maxLength="200"
            android:scrollHorizontally="false" />

        <Button
            android:fontFamily="sans-serif-medium"
            android:id="@+id/send_comment"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="16sp"
            android:textColor="@color/colorPrimary"
            android:layout_marginTop="8dp"
            android:text="@string/send"
            android:background="@null"
            android:layout_below="@id/write_comment"
            android:layout_alignParentRight="true"
            android:layout_alignParentBottom="true"
            android:textAllCaps="false" />
    </RelativeLayout>

将所有编辑文本和按钮放在滚动视图中。

<ScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical">
               <Edittext
               <EditText
               <EditText
               <Btn
             </LinearLayout
        </scrollview

Answer 3

我的解决方案是在您的布局中添加 ScrollView 作为根视图，并将覆盖视图的 onSizeChanged method. If height of EditText increases and Keyboard is blocking your button, Smooth Scroll 添加到您的按钮。

希望对您有所帮助。

我试过你的 Layout 一切都很完美，这不是问题。

But you need to make changes to your manifest where you declared your activity using more properties to android:configChanges.

Do this inside your android manifest.xml file.

     <activity
            android:name="<Name of project>.activity.Comments"
            android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
            android:label="Comments"
            android:screenOrientation="portrait"
            android:theme="@style/AppTheme.NoActionBar"
            android:windowSoftInputMode="stateHidden|adjustResize"/>

这是我使用的XML。

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
