我在新的Android KitKat（4.4）和windowSoftInputMode="adjustResize"中遇到了半透明动作条/导航栏的问题。
Normaly将InputMode更改为adjustResize，应用程序应该在键盘显示时自行调整大小......但是在这里它不会！如果我删除透明效果的行，则调整大小正常。
因此，如果键盘可见，我的ListView就在它下面，我无法访问最后几个项目。 （只能手动隐藏键盘）

有没有想法解决这个问题？
您缺少以下属性：
android:fitsSystemWindows="true"
在片段.xml布局的根RelativeLayout中。
更新：
去年Chris Bane发表了一篇有趣的演讲，详细解释了这是如何工作的：
最佳实践允许用户在显示键盘时滚动内容。因此，要添加此功能，您需要将根布局放在public final class ZeroInsetsFrameLayout extends FrameLayout {
private int[] mInsets = new int[4];
public ZeroInsetsFrameLayout(Context context) {
super(context);
}
public ZeroInsetsFrameLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ZeroInsetsFrameLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public final int[] getInsets() {
return mInsets;
}
@Override
public WindowInsets computeSystemWindowInsets(WindowInsets in, Rect outLocalInsets) {
outLocalInsets.left = 0;
outLocalInsets.top = 0;
outLocalInsets.right = 0;
return super.computeSystemWindowInsets(in, outLocalInsets);
}
@Override
protected final boolean fitSystemWindows(@NonNull Rect insets) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
// Intentionally do not modify the bottom inset. For some reason,
// if the bottom inset is modified, window resizing stops working.
// TODO: Figure out why.
mInsets[0] = insets.left;
mInsets[1] = insets.top;
mInsets[2] = insets.right;
insets.left = 0;
insets.top = 0;
insets.right = 0;
}
return super.fitSystemWindows(insets);
}
}
中并使用<com.dhna.widget.ZeroInsetsFrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:background="@color/white">
<!-- your xml code -->
</ZeroInsetsFrameLayout>
活动方法。
但是如果你想在Android 5上使用ScrollView旗帜这个功能，内容将无法滚动，并且会与键盘重叠。
要解决此问题，请检查此windowSoftInputMode="adjustResize"
它不适用于半透明状态栏;该设置强制窗口进入全屏模式，该模式不适用于adjustResize。
您可以使用adjustPan或使用fitsSystemWindows属性。我建议阅读有关该功能，但它有很多副作用：
<item name="android:windowTranslucentStatus">true</item>
XML
answer
活动
https://medium.com/google-developers/why-would-i-want-to-fitssystemwindows-4e26d9ce1eec
创建了Func
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<!-- Your xml -->
</RelativeLayout>
最后在清单中添加一些行
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView("Your Activity");
setAdjustScreen();
}
我有同样的问题。我已经解决了使用coordinatorlayout
activity.main.xml
protected void setAdjustScreen(){
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
/*android:windowSoftInputMode="adjustPan|adjustResize"*/
}
content_main2.xml
<activity
android:name="Your Activity"
android:windowSoftInputMode="adjustPan|adjustResize"
android:screenOrientation="portrait"></activity>
main activity.Java
现在添加此行linearLayoutManager.setStackFromEnd（true）;
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:layout_height="match_parent" android:layout_width="match_parent"

有一个相关的错误报告here。我找到了一种解决方法，从有限的测试来看，似乎没有任何影响。使用下面的逻辑添加你的根ViewGroup的自定义实现（我几乎总是使用FrameLayout，所以这是我测试过的）。然后，使用此自定义布局代替根布局，并确保设置android:fitsSystemWindows="true"。然后，您可以在布局后随时调用getInsets()（例如，添加OnPreDrawListener）以调整布局的其余部分以考虑系统插入，如果需要。

public final class CustomInsetsFrameLayout extends FrameLayout {
private int[] mInsets = new int[4];

mInsets[0] = insets.left;
mInsets[1] = insets.top;
mInsets[2] = insets.right;
insets.left = 0;
insets.top = 0;
insets.right = 0;
}
return super.fitSystemWindows(insets);
}
}
由于fitSystemWindows已弃用，请参阅以下答案以完成解决方法。
@kcoppock的回答非常有用，但是在API级别20中不推荐使用fitSystemWindows
因此，自API 20（KITKAT_WATCH）以来，您应该覆盖onApplyWindowInsets
@Override
public final WindowInsets onApplyWindowInsets(WindowInsets insets) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
return super.onApplyWindowInsets(insets.replaceSystemWindowInsets(0, 0, 0,
insets.getSystemWindowInsetBottom()));
} else {
return insets;
}
}
这对我来说在片段中有半透明状态栏和adjustResize：
public class CustomRelativeLayout extends RelativeLayout {
private int[] mInsets = new int[4];
public CustomRelativeLayout(Context context) {
super(context);
}
public CustomRelativeLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomRelativeLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
public CustomRelativeLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}
@Override
public final WindowInsets onApplyWindowInsets(WindowInsets insets) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
mInsets[0] = insets.getSystemWindowInsetLeft();
mInsets[1] = insets.getSystemWindowInsetTop();
mInsets[2] = insets.getSystemWindowInsetRight();
return super.onApplyWindowInsets(insets.replaceSystemWindowInsets(0, 0, 0,
insets.getSystemWindowInsetBottom()));
} else {
return insets;
}
}
}
然后在xml中，
<com.blah.blah.CustomRelativeLayout 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:fitsSystemWindows="true">
</com.blah.blah.CustomRelativeLayout>
如果要自定义插图并且您的目标是API级别> = 21，则无需创建自定义视图组即可完成此操作。通过设置fitsSystemWindows填充默认情况下将应用于容器视图，您可能不需要。
版本检查内置于此方法中，只有设备> = 21才会执行lambda中的代码。科特林的例子：
ViewCompat.setOnApplyWindowInsetsListener(container) { view, insets ->
insets.replaceSystemWindowInsets(0, 0, 0, insets.systemWindowInsetBottom).apply {
ViewCompat.onApplyWindowInsets(view, this)
}
}
确保您的布局仍设置fitsSystemWindows标志，否则将不会调用窗口insets侦听器。
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
/>

我有同样的问题，我的活动有一个ScrollView作为根视图和半透明状态栏激活它没有正确调整大小键盘显示...并且因此屏幕没有滚动隐藏输入视图。
解决方案：将所有内容（布局和活动逻辑）移动到新的片段中。然后将Activity更改为仅包含此Fragment。现在一切都按预期工作！
这是活动的布局：
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/contentView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true" />
基于约瑟夫约翰逊在Android How to adjust layout in Full Screen Mode when softkeyboard is visible的解决方法
在你的活动中在onCreate()之后在setContentView()中称呼这个。
AndroidBug5497Workaround.assistActivity(this);
与qazxsw poi中的qazxsw poi取代return (r.bottom - r.top);有点不同
出于某种原因，我必须将我的活动return r.bottom;属性设置为computeUsableHeight()。
这个解决方法救了我。它对我有用。希望可以帮到你。
实现类是：
fitsSystemWindowsAndroidBug5497Workaround.java注意内存泄漏。需要下面的代码
false我的示例使用RxJava在Activity的生命周期中的onPause（）时自动调用removeOnGlobalLayoutListener（）
public class AndroidBug5497Workaround {
// For more information, see https://code.google.com/p/android/issues/detail?id=5497
// 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;
}
}
我有一个问题。
我将windowDrawsSystemBarBackgrounds设置为'true'，我的应用程序应显示在状态栏下。
