Question

我正在使用此库：https://github.com/yshrsmz/KeyboardVisibilityEvent来检测键盘何时打开或关闭，这依赖于android:windowSoftInputMode="adjustResize"输入到Android清单。

这个库非常适合检测软键盘的打开和关闭事件，但由于adjustResize参数，我的内容被推出视图。

Java：

KeyboardVisibilityEvent.setEventListener(
        AddActivity.this,
        new KeyboardVisibilityEventListener() {
            @Override
            public void onVisibilityChanged(boolean isOpen) {
                // some code depending on keyboard visiblity status
                if (noteEditText.isFocused()) {
                    if (isOpen) {
                        Log.d("KB", "Keyboard is open");
                        noteEditText.setLines(12);
                        noteEditText.setCursorVisible(true);
                    } else {
                        Log.d("KB", "Keyboard is closed");
                        noteEditText.setLines(50);
                        noteEditText.setCursorVisible(false);
                    }
                }
            }
        });

noteEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        Log.d("KB", "onFocusChange");

        if (firstStart) {
            noteEditText.setLines(12);
            noteEditText.setCursorVisible(true);
            firstStart = false;
        }
    }
});

XML：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/add_record"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="20dp"
android:windowSoftInputMode="stateHidden">

<EditText
    android:id="@+id/title_edittext"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:hint="@string/enter_title"
    android:inputType="textCapSentences"
    android:textColor="@color/fontPrimary"
    android:theme="@style/EditTextCustomCursor">

    <requestFocus />
</EditText>

<EditText
    android:id="@+id/note_edittext"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@null"
    android:ellipsize="end"
    android:gravity="top|left"
    android:hint="@string/enter_note"
    android:inputType="textCapSentences|textMultiLine"
    android:lines="50"
    android:maxLines="20"
    android:minLines="5"
    android:paddingLeft="5dp"
    android:scrollHorizontally="false"
    android:scrollbars="vertical"
    android:textColor="@color/fontPrimary"
    android:theme="@style/EditTextCustomCursor" />

所以这可以通过调整第二个EditText的行来实现，然后我在键盘上方键入，但是当我关闭键盘时，滚动到EditText的底部并单击底部，EditText光标放在哪里我点击但是然后它将第一个EditText和Support ActionBar推出视图并在底部留下一个大的间隙（如下图中的图像（图像2）所示，因为选择了'F'，即EditText的底部）。

所需效果（全部位于正确位置）
实际效果（支持ActionBar和顶部EditText移出视图）

我还尝试过使用'adjustNothing'并执行以下操作，但这似乎不起作用，因为EditText高度在更改行数并且仅在更改行数时才会更改它知道键盘是打开还是关闭。

private void setupListeners() {

    final View activityRootView = getWindow().getDecorView().findViewById(android.R.id.content);
    activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {

            View mainView = (LinearLayout) findViewById(R.id.add_record);
            int heightDiff = mainView.getHeight() - noteEditText.getHeight();
            Log.d("KB", "HeightDiff: " + heightDiff);
            if (heightDiff > 1000 || keyboardShown) { // 99% of the time the height diff will be due to a keyboard.
                Log.d("KB", "Keyboard is open");

                if (isKeyboardVisible) {
                    noteEditText.setLines(12);
                    noteEditText.setCursorVisible(true);
                    noteEditText.requestLayout();
                    isKeyboardVisible = false;
                }
            } else {
                Log.d("KB", "Keyboard is closed");

                if (!isKeyboardVisible) {
                    noteEditText.setLines(50);
                    noteEditText.setCursorVisible(false);
                    noteEditText.requestLayout();
                    isKeyboardVisible = true;
                }
            }
        }
    });

    noteEditText.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            numTimesClicked++;
            Log.d("KB", "onClick: " + numTimesClicked);

            if (clicked) {
                // Run function
                Log.d("KB", "clicked");
                InputMethodManager imm = (InputMethodManager) AddActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);

                if (imm.isAcceptingText()) {
                    Log.d("KB", "Software Keyboard was shown");
                    isKeyboardVisible = true;
                    keyboardShown = true;
                } else {
                    Log.d("KB", "Software Keyboard was not shown");
                    isKeyboardVisible = false;
                    keyboardShown = false;
                }
            } else {
                Log.d("KB", "scroll");
                clicked = true;
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        clicked = false;
                    }
                }, 3 * 1000);
            }
        }
    });

    noteEditText.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
                Log.d("KB", "closeKeyboard");
                noteEditText.setLines(50);
                noteEditText.setCursorVisible(false);
                noteEditText.requestLayout();
                isKeyboardVisible = false;
            }
            return false;
        }
    });

因此，我将如何实现调整EditText行（打开和关闭键盘时）所需的效果，而不是将其他内容推出视图？那么支持ActionBar和第一个EditText总是保持在同一个位置，当软键盘出现时只调整第二个EditText？

Answer 1

我不确定，但我相信如果您将布局内容保留在RewriteBase / RewriteRule !\.(html|php)$ - [S=6] RewriteRule ^([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_(.*)$ $1-$2-$3-$4-$5-$6-$7 [E=underscores:Yes] RewriteRule ^([^_]*)_([^_]*)_([^_]*)_([^_]*)_([^_]*)_(.*)$ $1-$2-$3-$4-$5-$6 [E=underscores:Yes] RewriteRule ^([^_]*)_([^_]*)_([^_]*)_([^_]*)_(.*)$ $1-$2-$3-$4-$5 [E=underscores:Yes] RewriteRule ^([^_]*)_([^_]*)_([^_]*)_(.*)$ $1-$2-$3-$4 [E=underscores:Yes] RewriteRule ^([^_]*)_([^_]*)_(.*)$ $1-$2-$3 [E=underscores:Yes] RewriteRule ^([^_]*)_(.*)$ $1-$2 [E=underscores:Yes] RewriteCond %{ENV:underscores} ^Yes$ RewriteRule (.*) http://www.askapache.com/$1 [R=301,L]下，并且每当用户输入新行或新词时，您都会设置ScrollView。另外，您可以使用scrollView.scrollTo(0,0)代替此库，参考here

您也可以使用ViewTreeObserver进行管理，这是一种更好的做法。

Answer 2

我现在设法解决了这个问题（不是最好的解决方案），但确实有效。现在，顶部的EditText和Support ActionBar永远不会被推出视图，第二个EditText会自行调整大小，无论选择哪一行。

清单：

<activity android:theme="@style/AppTheme"
        android:name=".activities.AddActivity"
        android:label="@string/add_record"
        android:windowSoftInputMode="stateVisible|adjustResize"
        android:parentActivityName=".MainActivity"
        android:excludeFromRecents="true"/>
    <activity android:theme="@style/AppTheme"
        android:name=".activities.ModifyActivity"
        android:label="@string/modify_record"
        android:windowSoftInputMode="stateAlwaysHidden|adjustResize"
        android:parentActivityName=".MainActivity"
        android:excludeFromRecents="true"/>

Java：

private void setupListeners() {

    final LinearLayout linearLayout = (LinearLayout) findViewById(R.id.add_record);
    if (linearLayout != null) {
        linearLayout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "Clicking ll");
                noteEditText.requestFocus();

                InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                inputMethodManager.toggleSoftInputFromWindow(linearLayout.getApplicationWindowToken(),
                        InputMethodManager.SHOW_FORCED, 0);
            }
        });
    }

    KeyboardVisibilityEvent.setEventListener(
            AddActivity.this,
            new KeyboardVisibilityEventListener() {
                @Override
                public void onVisibilityChanged(boolean isOpen) {
                    // some code depending on keyboard visiblity status
                    Log.d(TAG, "Keyboard visibility changed");

                    int currentLine = getCurrentCursorLine(noteEditText);

                    lineCount = noteEditText.getLineCount();

                    if (isOpen && keyboardActuallyOpen) {
                        Log.d(TAG, "Keyboard is open");
                        //keyboardActuallyClosed = false;

                            /*
                            scrollView.fullScroll(View.FOCUS_UP);
                            noteEditText.requestFocus();
                            */

                        if (currentLine < 25) {

                            getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_NOTHING);

public class ExtendedEditText extends EditText {

public ExtendedEditText(Context context, AttributeSet attrs, int defStyle) {

}

public ExtendedEditText(Context context, AttributeSet attrs) {
    super(context, attrs);

}

public ExtendedEditText(Context context) {
    super(context);

}

@Override
public boolean onKeyPreIme(int keyCode, KeyEvent event) {
    if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
        dispatchKeyEvent(event);
