问题描述
我已经研究了很多来调整软键盘激活时的布局并且我已经成功实现它但是当我使用 android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 时出现问题清单文件中我的活动标记中的代码.
I have researched a lot to adjust the layout when softkeyboard is active and I have successfully implemented it but the problem comes when I use android:theme="@android:style/Theme.NoTitleBar.Fullscreen" this in my activity tag in manifest file.
为此，我使用了 android:windowSoftInputMode="adjustPan|adjustResize|stateHidden" 不同的选项，但没有运气.
For this I have used android:windowSoftInputMode="adjustPan|adjustResize|stateHidden" with different options but no luck.
在那之后，我以编程方式实现了 FullScreen 并尝试了各种布局来使用 FullScreen 但一切都是徒劳的.
After that I implemented FullScreen programmatically and tried various layout to work with FullScreen but all in vain.
我参考了这些链接，并在此处查看了许多与此问题相关的帖子:
I referred these links and have looked many posts here related to this issue:

这里是xml代码:

android:layout_width="fill_parent" android:layout_height="wrap_content">

android:layout_height="fill_parent" android:orientation="vertical">
<TextView android:id="@+id/setup_txt" android:layout_width="wrap_content"

android:layout_width="fill_parent" android:layout_height="50px"

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>
我希望当软键盘出现时，底部的 2 个按钮应该向上.
I want the bottom 2 buttons should go upward when the softkeyboard comes in picture.
推荐答案
基于 yghm 的变通方法，我编写了一个方便的类，可以让我用单线解决问题(在将新类添加到我的源代码后当然).单线是:
Based on yghm's workaround, I coded up a convenience class that allows me to solve the problem with a one-liner (after adding the new class to my source code of course). The one-liner is:
AndroidBug5497Workaround.assistActivity(this);
而实现类是:
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);
}
}
希望这对某人有所帮助.
