当软键盘处于活动状态并且我已成功实现它时,我已经研究了很多调整布局但是当我在清单文件中的活动标记中使用android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
时会出现问题。
为此,我使用android:windowSoftInputMode="adjustPan|adjustResize|stateHidden"
使用了不同的选项,但没有运气。
之后我以编程方式实施了FullScreen
并尝试了各种布局以便与FullScreen
一起使用,但都是徒劳的。
我引用了这些链接,并在此处查看了许多与此问题相关的帖子:

根据yghm的解决方法,我编写了一个便利类,允许我用一行代码解决问题(当然,在将新类添加到我的源代码之后)。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);
}
}
希望这有助于某人。

答案 2 :(得分:34)
由于答案已被挑选并且已知问题是一个错误,我想我会添加一个“可能的工作”。
显示软键盘时,您可以切换全屏模式。这允许“adjustPan”正常工作。
换句话说,我仍然使用 @android:style / Theme.Black.NoTitleBar.Fullscreen 作为应用主题的一部分, stateVisible | adjustResize 作为活动窗口软输入模式的一部分,但要让它们一起工作,我必须在键盘出现之前切换全屏模式。
使用以下代码:
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

我尝试了solution from Joseph Johnson,但与其他人一样,我遇到了内容与键盘之间的差距问题。出现此问题的原因是,在使用全屏模式时,软输入模式始终为 pan 。当您激活将被软输入隐藏的输入字段时,此平移会干扰Joseph的解决方案。
当出现软输入时,首先根据其原始高度平移内容,然后按照Joseph解决方案请求的布局调整内容大小。调整大小和后续布局不会撤消平移,这会导致间隙。事件的完整顺序是:
无法禁用平移,但可以通过更改内容的高度来强制平移偏移为0。这可以在侦听器中完成,因为它在平移发生之前运行。将内容高度设置为可用高度可以获得流畅的用户体验,即没有闪烁。
我也做了这些改变。如果其中任何一个引入问题,请告诉我:
getWindowVisibleDisplayFrame
的可用高度。 Rect
被缓存以防止一点不需要的垃圾。已经在Nexus 5和运行API级别为16-24的模拟器上进行了测试,屏幕尺寸从小到大。
代码已移植到Kotlin,但将我的更改移植回Java很简单。如果您需要帮助,请告诉我们:
class AndroidBug5497Workaround constructor(activity: Activity) {
private val contentContainer = activity.findViewById(android.R.id.content) as ViewGroup
private val rootView = contentContainer.getChildAt(0)
private val rootViewLayout = rootView.layoutParams as FrameLayout.LayoutParams
private val viewTreeObserver = rootView.viewTreeObserver
private val listener = ViewTreeObserver.OnGlobalLayoutListener { possiblyResizeChildOfContent() }

// Change the bounds of the root view to prevent gap between keyboard and content, and top of content positioned above top screen edge.

如果您使用系统UI方法(https://developer.android.com/training/system-ui/immersive.html),我刚刚找到了一个简单可靠的解决方案。
适用于使用View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
的情况,例如如果您使用CoordinatorLayout
。
它不会适用于WindowManager.LayoutParams.FLAG_FULLSCREEN
(您也可以使用android:windowFullscreen
在主题中设置的那个),但您可以使用SYSTEM_UI_FLAG_LAYOUT_STABLE
(&#34}实现类似效果;具有相同的视觉效果&#34; according to the docs),此解决方案应该再次起作用。
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION /* If you want to hide navigation */
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE)
我在运行Marshmallow的设备上测试了它。
关键是软键盘也是系统窗口之一(例如状态栏和导航栏),因此系统调度的WindowInsets
包含准确可靠的信息。
对于我们试图在状态栏后面绘制的DrawerLayout
中的用例,我们可以创建一个只忽略顶部插图的布局,并应用底部插图来说明软键盘。
这是我的自定义FrameLayout
:
/**
* Implements an effect similar to {@code android:fitsSystemWindows="true"} on Lollipop or higher,
* except ignoring the top system window inset. {@code android:fitsSystemWindows="true"} does not
* and should not be set on this layout.
*/
public class FitsSystemWindowsExceptTopFrameLayout extends FrameLayout {
public FitsSystemWindowsExceptTopFrameLayout(Context context) {
super(context);
}
public FitsSystemWindowsExceptTopFrameLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public FitsSystemWindowsExceptTopFrameLayout(Context context, AttributeSet attrs,
int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@RequiresApi(Build.VERSION_CODES.LOLLIPOP)
public FitsSystemWindowsExceptTopFrameLayout(Context context, AttributeSet attrs,
int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}
@Override
public WindowInsets onApplyWindowInsets(WindowInsets insets) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
setPadding(insets.getSystemWindowInsetLeft(), 0, insets.getSystemWindowInsetRight(),
insets.getSystemWindowInsetBottom());
return insets.replaceSystemWindowInsets(0, insets.getSystemWindowInsetTop(), 0, 0);
} else {
return super.onApplyWindowInsets(insets);
}
}
}
使用它:
<com.example.yourapplication.FitsSystemWindowsExceptTopFrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Your original layout here -->
</com.example.yourapplication.FitsSystemWindowsExceptTopFrameLayout>
理论上,这应该适用于任何没有疯狂修改的设备,比试图将随机1/3
或1/4
屏幕尺寸作为参考的任何黑客都要好得多。
(它需要API 16+,但我只在Lollipop +上使用全屏来绘制状态栏,因此在这种情况下它是最佳解决方案。)

我也不得不面对这个问题并且有一个工作,我检查了HTC one,galaxy s1,s2,s3,note和HTC感觉。
在布局的根视图上放置一个全局布局侦听器
mRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener(){
public void onGlobalLayout() {
checkHeightDifference();
}
});
并且在那里我检查了高度差,如果屏幕的高度差大于屏幕高度的三分之一,那么我们可以假设键盘是打开的。 从this answer获得了它。
private void checkHeightDifference(){
// get screen frame rectangle
Rect r = new Rect();
mRootView.getWindowVisibleDisplayFrame(r);
// get screen height
int screenHeight = mRootView.getRootView().getHeight();
// calculate the height difference
int heightDifference = screenHeight - (r.bottom - r.top);
// if height difference is different then the last height difference and
// is bigger then a third of the screen we can assume the keyboard is open
if (heightDifference > screenHeight/3 && heightDifference != mLastHeightDifferece) {
// keyboard visiblevisible
// get root view layout params
FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
// set the root view height to screen height minus the height difference
lp.height = screenHeight - heightDifference;
// call request layout so the changes will take affect
.requestLayout();
// save the height difference so we will run this code only when a change occurs.
mLastHeightDifferece = heightDifference;
} else if (heightDifference != mLastHeightDifferece) {
// keyboard hidden
PFLog.d("[ChatroomActivity] checkHeightDifference keyboard hidden");
// get root view layout params and reset all the changes we have made when the keyboard opened.
FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
lp.height = screenHeight;
// call request layout so the changes will take affect
mRootView.requestLayout();
// save the height difference so we will run this code only when a change occurs.
mLastHeightDifferece = heightDifference;
}
}
这可能不是防弹,也许在某些设备上它不起作用,但它对我有用,并希望它也会帮助你。

请注意,为活动设置android:windowSoftInputMode="adjustResize"
时,WindowManager.LayoutParams.FLAG_FULLSCREEN
不起作用。 您有两种选择。
为您的活动禁用全屏模式。在全屏模式下不会调整活动的大小。您可以在xml中(通过更改活动的主题)或在Java代码中执行此操作。在onCreate()方法中添加以下行。
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);`
或强>
使用其他方法实现全屏模式。在onCreate()方法中添加以下代码。
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);`
请注意,方法2仅适用于Android 4.1及更高版本。

实际上,无论我在Activity
模式中选择windowSoftInputMode
,我都会以任何方式影响软键盘外观。FullScreen
虽然我找不到关于这个属性的很多文档,但我认为FullScreen

在打开键盘之前创建容器高度的静态值
键盘打开时根据usableHeightSansKeyboard - heightDifference
设置容器高度,关闭时将其设置回保存的值
if (heightDifference > (usableHeightSansKeyboard / 4)) {
// keyboard probably just became visible
frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
int mStatusHeight = getStatusBarHeight();
frameLayoutParams.topMargin = mStatusHeight;
((MainActivity)activity).setMyMainHeight(usableHeightSansKeyboard - heightDifference);
if(BuildConfig.DEBUG){
Log.v("aBug5497", "keyboard probably just became visible");
}
} else {
// keyboard probably just became hidden
if(usableHeightPrevious != 0) {
frameLayoutParams.height = usableHeightSansKeyboard;
((MainActivity)activity).setMyMainHeight();
}
frameLayoutParams.topMargin = 0;
if(BuildConfig.DEBUG){
Log.v("aBug5497", "keyboard probably just became hidden");
}
}
MainActivity中的方法
public void setMyMainHeight(final int myMainHeight) {
runOnUiThread(new Runnable() {
@Override
public void run() {
ConstraintLayout.LayoutParams rLparams = (ConstraintLayout.LayoutParams) myContainer.getLayoutParams();
rLparams.height = myMainHeight;
myContainer.setLayoutParams(rLparams);
}
});
}
int mainHeight = 0;
public void setMyMainHeight() {
runOnUiThread(new Runnable() {
@Override
public void run() {
ConstraintLayout.LayoutParams rLparams = (ConstraintLayout.LayoutParams) myContainer.getLayoutParams();
rLparams.height = mainHeight;
myContainer.setLayoutParams(rLparams);
}
});
}
示例容器XML
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.constraint.ConstraintLayout
android:id="@+id/my_container"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintHeight_percent=".8">
如果需要,可以添加页边距...
另一个考虑因素是使用填充,可以在以下位置找到其示例:

1)创建KeyboardHeightHelper:
public class KeyboardHeightHelper {
private final View decorView;
private int lastKeyboardHeight = -1;
public KeyboardHeightHelper(Activity activity, View activityRootView, OnKeyboardHeightChangeListener listener) {
this.decorView = activity.getWindow().getDecorView();
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(() -> {
int keyboardHeight = getKeyboardHeight();
if (lastKeyboardHeight != keyboardHeight) {
lastKeyboardHeight = keyboardHeight;
listener.onKeyboardHeightChange(keyboardHeight);
}
});
}
private int getKeyboardHeight() {
Rect rect = new Rect();
decorView.getWindowVisibleDisplayFrame(rect);
return decorView.getHeight() - rect.bottom;
}
public interface OnKeyboardHeightChangeListener {
void onKeyboardHeightChange(int keyboardHeight);
}
}
2)让您的活动全屏显示:
activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
3)监听键盘高度的变化并为视图添加底部填充:
View rootView = activity.findViewById(R.id.root); // your root view or any other you want to resize
KeyboardHeightHelper effectiveHeightHelper = new KeyboardHeightHelper(
activity,
rootView,
keyboardHeight -> rootView.setPadding(0, 0, 0, keyboardHeight));
因此,每次键盘出现在屏幕上-您视图的底部填充都会更改,内容也会重新排列。

今天对于全屏问题,adjustResize对于android sdk来说是实际的。
从答案中我发现:
the solution -但是解决方案在图片上显示了这个问题:
比我发现the solution 并删除了一项不必要的操作:
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
因此,请在Kotlin上查看我的固定解决方案代码:
class AndroidBug5497Workaround constructor(val activity: Activity) {
private val content = activity.findViewById<View>(android.R.id.content) as FrameLayout
private val mChildOfContent = content.getChildAt(0)
private var usableHeightPrevious: Int = 0
private val contentContainer = activity.findViewById(android.R.id.content) as ViewGroup
private val rootView = contentContainer.getChildAt(0)
private val rootViewLayout = rootView.layoutParams as FrameLayout.LayoutParams
private val listener = {
possiblyResizeChildOfContent()
}
fun addListener() {
mChildOfContent.apply {
viewTreeObserver.addOnGlobalLayoutListener(listener)
}
}
fun removeListener() {
mChildOfContent.apply {
viewTreeObserver.removeOnGlobalLayoutListener(listener)
}
}
private fun possiblyResizeChildOfContent() {
val contentAreaOfWindowBounds = Rect()
mChildOfContent.getWindowVisibleDisplayFrame(contentAreaOfWindowBounds)
val usableHeightNow = contentAreaOfWindowBounds.height()
if (usableHeightNow != usableHeightPrevious) {
rootViewLayout.height = usableHeightNow
rootView.layout(contentAreaOfWindowBounds.left,
contentAreaOfWindowBounds.top, contentAreaOfWindowBounds.right, contentAreaOfWindowBounds.bottom);
mChildOfContent.requestLayout()
usableHeightPrevious = usableHeightNow
}
}
}

请勿使用:
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
因为效果不好。 代替该使用:
fun setFullScreen(fullScreen: Boolean) {
val decorView = getWindow().getDecorView()
val uiOptions : Int
if(fullScreen){
uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN // this hide statusBar
toolbar.visibility = View.GONE // if you use toolbar
tabs.visibility = View.GONE // if you use tabLayout
} else {
uiOptions = View.SYSTEM_UI_FLAG_VISIBLE // this show statusBar
toolbar.visibility = View.VISIBLE
tabs.visibility = View.VISIBLE
}
decorView.setSystemUiVisibility(uiOptions)
}

private void resizeWindowOnKeyboardVisible() {
RelativeLayout rootLayout;
rootLayout = findViewById(R.id.rootLayout);
this.getWindow().getDecorView().getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
ViewGroup.LayoutParams layoutParams = rootLayout.getLayoutParams();
int height ;
@Override
public void onGlobalLayout() {
Rect r = new Rect();
getWindow().getDecorView().getWindowVisibleDisplayFrame(r);
int screenHeight = rootLayout.getContext().getResources().getDisplayMetrics().heightPixels;
int heightDiff = screenHeight - r.bottom;
if (heightDiff > screenHeight*0.15)
{
height = screenHeight - heightDiff;
layoutParams.height=height;
rootLayout.setLayoutParams(layoutParams);
}else{
height=ViewGroup.LayoutParams.MATCH_PARENT;
if( height!=layoutParams.height) {
layoutParams.height = height;
rootLayout.setLayoutParams(layoutParams);
}
}
}
});
}
使用 android:windowSoftInputMode="adjustResize|stateHidden 可能不适用于所有情况,而且 android:fitsSystemWindows="true 在您使用 SYSTEM_UI_FLAG_FULLSCREEN 标签时也无济于事。要在键盘可见时调整视图/窗口/网络视图,请执行以下操作。
它也适用于 Android 11 (API 30)。

我尝试了许多解决方案,包括Joseph Johnson和Johan Stuyts。但结果是,在所有情况下,我在某些设备(如联想s820)上的内容和键盘之间都有一个空白区域。 所以我对他们的代码做了一些修改,最后得到了解决方案。
我的想法是在键盘显示时根据内容添加边距。
contentContainer.getWindowVisibleDisplayFrame(contentAreaOfWindowBounds);
int usableHeightNow = contentAreaOfWindowBounds.height();
if (usableHeightNow != usableHeightPrevious) {
int difference = usableHeightNow - usableHeightPrevious;
if (difference < 0 && difference < -150) {
keyboardShowed = true;
rootViewLayout.topMargin -= difference + 30;
rootViewLayout.bottomMargin += 30;
}
else if (difference < 0 && difference > -150){
rootViewLayout.topMargin -= difference + 30;
}
else if (difference > 0 && difference > 150) {
keyboardShowed = false;
rootViewLayout.topMargin = 0;
rootViewLayout.bottomMargin = 0;
}
rootView.requestLayout();
Log.e("Bug Workaround", "Difference: " + difference);
usableHeightPrevious = usableHeightNow;
}
正如您所看到的,我添加了30 px差异,因为屏幕顶部和内容区域之间有一个小的空白区域。而且我不知道它从哪里出现所以我决定将边距缩小,现在它的工作方式正是我需要的。

我只使用全屏模式隐藏状态栏。但是,我希望应用程序在显示键盘时调整大小。所有其他解决方案(可能由于帖子的年龄)都很复杂或不可能(我希望避免更改Java代码以解决PhoneGap Build的问题)。
我没有使用全屏,而是将我的Android配置修改为非全屏:
<preference name="fullscreen" value="false" />
并通过命令行添加cordova-plugin-statusbar
:
cordova plugin add cordova-plugin-statusbar
当app加载后,我简单地调用插件上的方法来隐藏自己,例如:
if (window.cordova && window.cordova.platformId == 'android' && window.StatusBar)
window.StatusBar.hide();
这就像一个魅力。唯一真正的缺点是,当应用程序加载时,状态栏是明显可见的。对于我的需求,这不是一个问题。

谢谢约瑟夫的回答。但是,在方法possibleResizeChildOfContent()中,部分
else {
// keyboard probably just became hidden
frameLayoutParams.height = usableHeightSansKeyboard;
}
对我不起作用,因为视图的下半部分被隐藏了。 所以我不得不采用全局变量restoreHeight,并在构造函数中插入最后一行
restoreHeight = frameLayoutParams.height;
然后我用
替换了前面提到的部分else {
// keyboard probably just became hidden
frameLayoutParams.height = restoreHeight;
}
但我不知道为什么你的代码对我不起作用。如果有人能够阐明这一点,那将是非常有帮助的。

您希望底栏粘在视图的底部,但是当显示键盘时,它们应向上移动以放置在键盘上方,对吧?
您可以尝试以下代码段:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
...>
<RelativeLayout
android:id="@+id/RelativeLayoutTopBar"
...>
</RelativeLayout>
<LinearLayout
android:id="@+id/LinearLayoutBottomBar"
android:layout_alignParentBottom = true
...>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="390dp"
android:orientation="vertical"
android:layout_above="@+id/LinearLayoutBottomBar"
android:layout_below="@+id/RelativeLayoutTopBar">
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:id="@+id/ScrollViewBackground">
...
</ScrollView>
</LinearLayout>
</RelativeLayout>
BottomBar将粘贴在视图的底部,包含ScrollView的LinearLayout将在顶部/底部栏和键盘显示后占据视图的左侧。如果它也适合你,请告诉我。

就我而言,一旦我将Crosswalk添加到我的Cordova应用程序中,这个问题就开始发生了。我的应用程序未在全屏和android中使用:windowSoftInputMode =“adjustPan”。
我已经在应用程序中安装了离子键盘插件,因此可以轻松检测键盘是上升还是下降:
// Listen for events to when the keyboard is opened and closed
window.addEventListener("native.keyboardshow", keyboardUp, false);
window.addEventListener('native.keyboardhide', keyboardDown, false);
function keyboardUp()
{
$('html').addClass('keyboardUp');
}
function keyboardDown()
{
$('html').removeClass('keyboardUp');
}
我尝试了上面的所有修复,但最后为我做的简单线就是这个css:
&.keyboardUp {
overflow-y: scroll;
}
希望这能节省你花在这上面的几天。 :)
