软键盘隐藏多行 EditText 下方的按钮？

Question

我有一个RelativeLayout与EditText具有Button下方。理想情况下，当用户单击EditText并填充多行文本时，RelativeLayout也会随着行的增加而扩展。但是，我现在的行为是，在EditText填充了 的第一行后，键盘开始覆盖其Button下方，并且在 中的 3-4 行文本之后EditText，Button消失在键盘下方。有没有办法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" />

评论.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>

我试图添加一个android:isScrollContainer="true"想法，即它会创建一个滚动容器，EditText以便它有助​​于扩展布局，但这似乎不起作用。任何帮助，将不胜感激。谢谢！

编辑：根据 Jaydroider 的要求，我附上了一张照片来展示我的问题。如果我可以制作 GIF 或其他东西，如果我在EditText字段中添加更多文本，该Send按钮将在键盘下方消失，除非我从 中删除文本，否则EditText无法按下“发送”：

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

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);
    }

我已经尝试过你的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使用更多属性来android:configChanges.

在您的文件中执行此操作android manifest.xml。

     <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。

I have tested with above changes and it's just working fine you can see below.

希望这将帮助您解决您的问题。
