我在新的Android KitKat (4.4) 和windowSoftInputMode="adjustResize".

通常，将InputMode更改为adjustResize，应用程序应在显示键盘时自行调整大小，但在这里不会！如果我删除透明效果的线条，则调整大小正在起作用。

所以如果键盘是可见的，我ListView就在它下面，我不能访问最后几个项目（只能通过手动隐藏键盘）。

AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>

您缺少以下属性：

android:fitsSystemWindows="true"

在片段.xml 布局的根目录RelativeLayout中。

更新：

去年 Chris Bane 进行了一次有趣的演讲，详细解释了这是如何工作的：

这里有一个相关的错误报告。我从有限的测试中找到了一种解决方法，似乎可以解决问题而没有任何影响。使用以下逻辑添加根的自定义实现ViewGroup（我几乎总是在使用FrameLayout，所以这是我测试过的）。然后，使用这个自定义布局代替你的根布局，并确保你设置了android:fitsSystemWindows="true". 如果需要，您可以getInsets()在布局后的任何时间调用（例如添加一个OnPreDrawListener）来调整布局的其余部分以考虑系统插图。

@kcoppock 的回答真的很有帮助，但 fitSystemWindows 在 API 级别 20 中已被弃用

因此，从 API 20 (KITKAT_WATCH) 开始，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;
    }
}

如果您想自定义插图并且您的目标 API 级别 >=21，则无需创建自定义视图组即可完成此操作。默认情况下，只需设置fitsSystemWindows填充将应用于您的容器视图，您可能不希望这样做。

版本检查内置在此方法中，只有 >= 21 的设备将执行 lambda 中的代码。科特林示例：

ViewCompat.setOnApplyWindowInsetsListener(container) { view, insets ->
  insets.replaceSystemWindowInsets(0, 0, 0, insets.systemWindowInsetBottom).apply {
    ViewCompat.onApplyWindowInsets(view, this)
  }
}

确保您的布局仍然设置fitsSystemWindows标志，否则不会调用窗口插入侦听器。

<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    />

这对我来说有半透明的状态栏和片段中的adjustResize：

  1. 像@Victor91 和@kcoppock 所说的那样制作一个自定义的RelativeLayout。

  2. 使用 CustomRelativeLayout 作为片段的父布局。

  3. 用 android:windowTranslucentStatus = true 声明主题

  4. 容器 Activity 必须在 Manifest 中声明为 android:windowSoftInputMode="adjustResize" 并使用声明的主题

  5. 请在片段根布局上使用 fitSystemWindows！

    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>

我遇到了同样的问题，我的 Activity 有一个 ScrollView 作为根视图，并且激活了半透明状态栏，当键盘显示时它没有正确调整大小......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）移动到一个新的 Fragment 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" />

由and方法弃用引起的有用的@Victor Rendina答案的小更新。replaceSystemWindowInsetssystemWindowInsetBottom

先决条件：

  • API >= 21
  • implementation 'androidx.core:core-ktx:1.5.0-alpha02'至少

Kotlin 扩展：

fun View?.fitSystemWindowsAndAdjustResize() = this?.let { view ->
    ViewCompat.setOnApplyWindowInsetsListener(view) { v, insets ->
        view.fitsSystemWindows = true
        val bottom = insets.getInsets(WindowInsetsCompat.Type.ime()).bottom

        WindowInsetsCompat
            .Builder()
            .setInsets(
                WindowInsetsCompat.Type.systemBars(),
                Insets.of(0, 0, 0, bottom)
            )
            .build()
            .apply {
                ViewCompat.onApplyWindowInsets(v, this)
            }
    }
}

用法：

rootView.fitSystemWindowsAndAdjustResize()

rootView从字面上看，布局的根视图在哪里:)

注意： 如果扩展不适用于您的根视图（我在使用ConstraintLayoutas时遇到了这种情况rootView）用 a 包裹整个布局，FrameLayout以便FrameLayout成为新的根视图。

首先将其添加到您的根布局中。

android:fitsSystemWindows="true"

当您使用这种方法时，您有责任确保应用程序 UI 的关键部分（例如，地图应用程序中的内置控件）最终不会被系统栏覆盖。这可能会使您的应用程序无法使用。在大多数情况下，您可以通过将 android:fitsSystemWindows 属性添加到 XML 布局文件中来处理这个问题，并将其设置为 true。这会调整父 ViewGroup 的填充以为系统窗口留出空间。这对于大多数应用程序来说已经足够了。

但是，在某些情况下，您可能需要修改默认填充以获得应用所需的布局。要直接操纵您的内容相对于系统栏的布局方式（占据称为窗口“内容插入”的空间），请覆盖 fitSystemWindows(Rect insets)。当窗口的内容插入发生变化时，视图层次结构会调用 fitSystemWindows() 方法，以允许窗口相应地调整其内容。通过覆盖此方法，您可以随心所欲地处理插图（以及因此您的应用程序的布局）。

基于 Joseph Johnson 在Android 中的解决方法 How to adjust layout in Full Screen Mode when softkeyboard is visible

onCreate()在setContentView()您的活动中调用它。

AndroidBug5497Workaround.assistActivity(this);

与原始版本略有不同替换return (r.bottom - r.top);为return r.bottom;incomputeUsableHeight()

出于某种原因，我必须将我的活动fitsSystemWindows属性设置为false.

这种解决方法救了我。它对我很有效。希望能帮到你。

实现类是：

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;
}

}

它不应该与半透明状态栏一起使用；该设置强制窗口进入全屏模式，这不适用于adjustResize。

您可以使用adjustPan 或使用fitsSystemWindows 属性。我建议阅读有关该功能的信息，但它具有显着的副作用：

我有一个问题。

我将 windowDrawsSystemBarBackgrounds 设置为“true”，我的应用程序应该显示在状态栏下。

这是我的活动主题。

<item name="android:windowTranslucentStatus" tools:targetApi="KITKAT">false</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>

我得到了建树博客的帮助。您可以阅读代码，但可以像我一样阅读文本。我添加了一些代码。

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);
    }
}

这是我的片段布局。

<com.dhna.widget.ZeroInsetsFrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="match_parent"
    android:fitsSystemWindows="true"

我有同样的问题。我已经使用 coordinatorlayout 解决了

活动.main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    android:layout_height="match_parent" android:layout_width="match_parent"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android">


    <android.support.design.widget.AppBarLayout
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:layout_height="?attr/actionBarSize"
        android:layout_width="match_parent"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        android:background="?attr/colorPrimary"
        android:id="@+id/toolbar"/>

</android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_main2"/>

</android.support.design.widget.CoordinatorLayout>

content_main2.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto">


    <android.support.v7.widget.RecyclerView
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:layout_marginTop="30dp"
        android:layout_marginBottom="30dp"
        app:layout_scrollFlags="scroll|exitUntilCollapsed"
        android:id="@+id/post_msg_recyclerview">
    </android.support.v7.widget.RecyclerView>

    <EditText
        android:layout_width="match_parent"
        android:layout_height="50dp"
        app:layout_constraintBottom_toBottomOf="parent"
        android:background="@color/colorPrimary"


        />

</android.support.constraint.ConstraintLayout>

MainActivity.java

现在添加这一行 linearLayoutManager.setStackFromEnd(true);

 LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
        linearLayoutManager.setStackFromEnd(true);
        recyclerView.setLayoutManager(linearLayoutManager);
        Adapter adapter1=new Adapter(arrayList);
        recyclerView.setAdapter(adapter1);

这是我在 xml 文件的主视图中使用的内容，您将添加它

android:animateLayoutChanges="true"

然后在“onCreate”函数中，您将在每件事之前获得状态栏大小，如下所示

int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0)
{
    status_bar=getResources().getDimensionPixelSize(resourceId);
}

然后最后在“onCreate”中添加这个来更新大小

        main_view= findViewById(R.id.the_main);
        main_view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener()
        {
            @Override
            public void onGlobalLayout()
            {
                Rect r = new Rect();
                View view = getWindow().getDecorView();
                view.getWindowVisibleDisplayFrame(r);
                if (Math.abs(old_size - r.height()) > 100)
                {
                    ViewGroup.LayoutParams params = main_view.getLayoutParams();
                    params.height = r.height()+ status_bar ;
                    main_view.setLayoutParams(params);
                }
                old_size = r.height();
            }
        });

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，您需要将根布局放入ScrollView并使用windowSoftInputMode="adjustResize"活动方法。

但是，如果您想在 Android 5 内容上将此功能与<item name="android:windowTranslucentStatus">true</item> 标志​​一起使用，则将无法滚动并且会与键盘重叠。

要解决此问题，请检查此答案

  • 在我研究了所有论坛之后。那些方法不由得找出来点。当我尝试这样做时很幸运。它帮助我解决了问题

XML

<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>

活动

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView("Your Activity");
   setAdjustScreen();

}

创建函数

protected void setAdjustScreen(){
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
        /*android:windowSoftInputMode="adjustPan|adjustResize"*/
}

最后在你的 mainifest 中添加一些行

 <activity
     android:name="Your Activity"
     android:windowSoftInputMode="adjustPan|adjustResize"
     android:screenOrientation="portrait"></activity>
