Android如何在软键盘可见时以全屏模式调整布局

我已经研究了很多东西来调整软键盘活动时的布局,并且我已经成功实现了它,但是当我在清单文件的activity标签中使用android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

为此,我使用了不同的选项android:windowSoftInputMode="adjustPan|adjustResize|stateHidden" ,但没有运气。

之后,我以编程方式实施FullScreen并尝试使用FullScreen各种布局,但都徒劳无功。

我介绍了这些链接,并在这里查看了许多与此问题相关的帖子:

这里是xml代码:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/masterContainerView"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="#ffffff">

    <ScrollView android:id="@+id/parentScrollView"
        android:layout_width="fill_parent" android:layout_height="wrap_content">

        <LinearLayout android:layout_width="fill_parent"

            <TextView android:id="@+id/setup_txt" android:layout_width="wrap_content"
                android:layout_height="wrap_content" android:text="Setup - Step 1 of 3"
                android:textColor="@color/top_header_txt_color" android:textSize="20dp"
                android:padding="8dp" android:gravity="center_horizontal" />

            <TextView android:id="@+id/txt_header" android:layout_width="fill_parent"

                android:textStyle="bold" android:padding="10dp"

            <EditText android:id="@+id/edit_message"
                android:layout_width="fill_parent" android:layout_height="wrap_content"
                android:text="Some text here." android:textSize="16dp"
                android:textColor="@color/setting_editmsg_color" android:padding="10dp"
                android:minLines="5" android:maxLines="6" android:layout_below="@+id/txt_header"
                android:gravity="top" android:scrollbars="vertical"
                android:maxLength="132" />

            <ImageView android:id="@+id/image_bottom"
                android:layout_width="fill_parent" android:layout_height="wrap_content"
                android:layout_below="@+id/edit_message" />

        </LinearLayout>
    </ScrollView>

    <RelativeLayout android:id="@+id/scoringContainerView"
        android:layout_width="fill_parent" android:layout_height="50px"
        android:orientation="vertical" android:layout_alignParentBottom="true"
        android:background="#535254">

        <Button android:id="@+id/btn_save" android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:layout_alignParentRight="true"
            android:layout_marginTop="7dp" android:layout_marginRight="15dp"
            android:layout_below="@+id/edit_message"
            android:text = "Save" />

        <Button android:id="@+id/btn_cancel" android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:layout_marginTop="7dp"
            android:layout_marginRight="10dp" android:layout_below="@+id/edit_message"
            android:layout_toLeftOf="@+id/btn_save" android:text = "Cancel" />

    </RelativeLayout>
</RelativeLayout>

当软键盘进入画面时,我希望底部的2个按钮应该向上。

基于yghm的解决方法,我编写了一个便利课程,让我可以用一行代码解决问题(将新课程添加到我的源代码当然)。 单线是:

     AndroidBug5497Workaround.assistActivity(this);

实现类是:


public class AndroidBug5497Workaround {

    // For more information, see https://issuetracker.google.com/issues/36911528
    // To use this class, simply invoke assistActivity() on an Activity that already has its content view set.

    public static void assistActivity (Activity activity) {
        new AndroidBug5497Workaround(activity);
    }

    private View mChildOfContent;
    private int usableHeightPrevious;
    private FrameLayout.LayoutParams frameLayoutParams;

    private AndroidBug5497Workaround(Activity activity) {
        FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);
        mChildOfContent = content.getChildAt(0);
        mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            public void onGlobalLayout() {
                possiblyResizeChildOfContent();
            }
        });
        frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();
    }

    private void possiblyResizeChildOfContent() {
        int usableHeightNow = computeUsableHeight();
        if (usableHeightNow != usableHeightPrevious) {
            int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();
            int heightDifference = usableHeightSansKeyboard - usableHeightNow;
            if (heightDifference > (usableHeightSansKeyboard/4)) {
                // keyboard probably just became visible
                frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
            } else {
                // keyboard probably just became hidden
                frameLayoutParams.height = usableHeightSansKeyboard;
            }
            mChildOfContent.requestLayout();
            usableHeightPrevious = usableHeightNow;
        }
    }

    private int computeUsableHeight() {
        Rect r = new Rect();
        mChildOfContent.getWindowVisibleDisplayFrame(r);
        return (r.bottom - r.top);
    }
}

希望这可以帮助某人。


由于答案已经被选中,而且问题已知是一个错误,我想我会添加一个“可能的解决方法”。

显示软键盘时,您可以切换全屏模式。 这使“adjustPan”能够正常工作。

换句话说,我仍然使用@android:style / Theme.Black.NoTitleBar.Fullscreen作为应用程序主题的一部分,并将stateVisible | adjustResize作为活动窗口软输入模式的一部分,但让它们一起工作我必须切换全屏模式在键盘出现之前。

使用下面的代码:

关闭全屏模式

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

打开全屏模式

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

注意 - 灵感来自:以全屏模式隐藏标题
