添加
android:windowSoftInputMode="adjustResize"
在您宣布此特定活动的AndroidManifest.xml中,这将调整布局调整大小选项。
下面的一些源代码用于布局设计

在 AndroidManifest.xml 中,不要忘记设置:
android:windowSoftInputMode="adjustResize"
在您需要此类布局的<activity>
标记上。
<强>思想:强>
我已经意识到RelativeLayout
是跨越所有可用空间的布局,然后在键盘弹出时调整大小。
LinearLayout
是在调整大小过程中不会调整大小的布局。
这就是为什么你需要在RelativeLayout
之后立即拥有1 ScrollView
来跨越所有可用的屏幕空间。并且你需要在LinearLayout
内部RelativeLayout
,否则在调整大小时你的内心会被粉碎。好的例子是&#34; headerLayout&#34;。如果在LinearLayout
&#34; facebook&#34;内部不存在RelativeLayout
。文字会被粉碎,不会被显示出来。
在&#34; facebook&#34;在问题中发布的登录图片我还注意到整个登录部分(mainLayout)相对于整个屏幕是垂直居中的,因此属性:
android:layout_centerVertical="true"
<{1>}布局上的。因为mainLayout位于LinearLayout
内,这意味着该部分不会调整大小(再次查看相关图片)。

它适用于所有类型的布局。

机器人:layout_alignParentBottom =&#34;真&#34;

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:fitsSystemWindows="true">
答案 5 :(得分:5)
这样就可以显示以前被键盘隐藏的任何想要的布局。
将此添加到AndroidManifest.xml中的activity标记
机器人:windowSoftInputMode = “adjustResize”
使用ScrollView环绕根视图,最好使用scrollbars = none。除了用于解决此问题之外,ScrollView将不会使用您的布局更改任何内容。
然后在要完全显示在键盘上方的视图上设置fitsSystemWindows =“true”。 这将使您的EditText在键盘上方可见,并且可以向下滚动到EditText下面的部分,但在视图中使用fitsSystemWindows =“true”。
机器人:fitsSystemWindows = “真”
例如:
<ScrollView
android:id="@+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="none">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
...
</android.support.constraint.ConstraintLayout>
</ScrollView>
如果你想在键盘出现的那一刻在键盘上方显示fitsSystemWindows =“true”视图的完整部分,你需要一些代码将视图滚动到底部:
// Code is in Kotlin
setupKeyboardListener(scrollView) // call in OnCreate or similar
private fun setupKeyboardListener(view: View) {
view.viewTreeObserver.addOnGlobalLayoutListener {
val r = Rect()
view.getWindowVisibleDisplayFrame(r)
if (Math.abs(view.rootView.height - (r.bottom - r.top)) > 100) { // if more than 100 pixels, its probably a keyboard...
onKeyboardShow()
}
}
}
private fun onKeyboardShow() {
scrollView.scrollToBottomWithoutFocusChange()
}
fun ScrollView.scrollToBottomWithoutFocusChange() { // Kotlin extension to scrollView
val lastChild = getChildAt(childCount - 1)
val bottom = lastChild.bottom + paddingBottom
val delta = bottom - (scrollY + height)
smoothScrollBy(0, delta)
}
完整布局示例:
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">

答案 6 :(得分:3)
许多答案是正确的。我在AndroidManifest
中写道:
<activity
android:name=".SomeActivity"
android:configChanges="orientation|keyboardHidden|screenSize" // Optional, doesn't affect.
android:theme="@style/AppTheme.NoActionBar"
android:windowSoftInputMode="adjustResize" />
就我而言,我在styles.xml
中添加了一个主题,但是您可以使用自己的主题:
<style name="AppTheme.NoActionBar" parent="AppTheme">
<!-- Hide ActionBar -->
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
</style>
我注意到,如果我使用全屏主题,则不会发生大小调整:
<style name="AppTheme.FullScreenTheme" parent="AppTheme">
<!-- Hide ActionBar -->
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<!-- Hide StatusBar -->
<item name="android:windowFullscreen">true</item>
</style>
在我看来,adjustResize
也有效,但adjustPan
无效。
对于全屏布局,请参见Android How to adjust layout in Full Screen Mode when softkeyboard is visible或https://gist.github.com/grennis/2e3cd5f7a9238c59861015ce0a7c5584中的解决方法。
https://medium.com/@sandeeptengale/problem-solved-3-android-full-screen-view-translucent-scrollview-adjustresize-keyboard-b0547c7ced32也可以使用,但是StatusBar是透明的,因此可以看到电池,时钟和Wi-Fi图标。
如果使用文件>新建>活动>全屏活动创建活动,则使用代码:
fullscreen_content.systemUiVisibility =
View.SYSTEM_UI_FLAG_LOW_PROFILE or
View.SYSTEM_UI_FLAG_FULLSCREEN or
View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY or
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION or
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
您也不会获得结果。您可以在根容器中使用android:fitsSystemWindows="true"
,但是StatusBar出现。因此,请使用第一个链接中的解决方法。
答案 7 :(得分:2)
您只需在AndroidManifest.xml文件中设置这些选项即可。
<activity
android:name=".YourACtivityName"
android:windowSoftInputMode="stateVisible|adjustResize">
Google不建议使用adjustPan
,因为用户可能需要关闭键盘才能看到所有输入字段。

现在最重要的部分!
在Activity

代码中使用此类主题。
android:theme="@style/AppTheme"
主题就是这样的
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>

<item name="colorAccent">@color/colorAccent</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="windowActionModeOverlay">true</item>

所以我错过了这个主题。这让我整天感到沮丧。

对于使用 ConstraintLayout 的用户,android:windowSoftInputMode="adjustPan|adjustResize"
将不起作用。
您可以使用soft keyboard listener,将视图的约束从上视图的底部到底部设置,然后为每个视图设置垂直偏差(以位置百分比表示)约束之间)到水平指南(也按百分比定位,但定位到父级)。
对于每个视图,我们只需要在显示键盘 时以编程方式将app:layout_constraintBottom_toBottomOf
更改为@+id/guideline
。
<ImageView
android:id="@+id/loginLogo"
...
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.15" />
<RelativeLayout
android:id="@+id/loginFields"
...
app:layout_constraintVertical_bias=".15"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="@+id/loginLogo">
<Button
android:id="@+id/login_btn"
...
app:layout_constraintVertical_bias=".25"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="@+id/loginFields"/>
通常,软键盘不超过屏幕高度的50%。因此,您可以将准则设置为0.5。
<android.support.constraint.Guideline
android:id="@+id/guideline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.5"/>
现在,以编程方式,当未显示键盘时,我们可以将所有app:layout_constraintBottom_toBottomOf
设置回父级,反之亦然。
unregistrar = KeyboardVisibilityEvent.registerEventListener(this, isOpen -> {
loginLayout.startAnimation(AnimationManager.getFade(200));
if (isOpen) {
setSoftKeyViewParams(loginLogo, R.id.guideline, ConstraintLayout.LayoutParams.PARENT_ID, -1, "235:64", 0.15f,
63, 0, 63, 0);
setSoftKeyViewParams(loginFields, R.id.guideline, -1, R.id.loginLogo, null, 0.15f,
32, 0, 32, 0);
setSoftKeyViewParams(loginBtn, R.id.guideline, -1, R.id.useFingerPrintIdText, null, 0.5f,
32, 0, 32, 0);
} else {
setSoftKeyViewParams(loginLogo, ConstraintLayout.LayoutParams.PARENT_ID, ConstraintLayout.LayoutParams.PARENT_ID, -1, "235:64", 0.15f,
63, 0, 63, 0);
setSoftKeyViewParams(loginFields, ConstraintLayout.LayoutParams.PARENT_ID, -1, R.id.loginLogo,null, 0.15f,
32, 0, 32, 0);
setSoftKeyViewParams(loginBtn, ConstraintLayout.LayoutParams.PARENT_ID, -1, R.id.useFingerPrintIdText,null, 0.25f,
32, 0, 32, 0);
}
});
调用此方法:
private void setSoftKeyViewParams(View view, int bottomToBottom, int topToTop, int topToBottom, String ratio, float verticalBias,
int left, int top, int right, int bottom) {
ConstraintLayout.LayoutParams viewParams = new ConstraintLayout.LayoutParams(view.getLayoutParams().width, view.getLayoutParams().height);
viewParams.dimensionRatio = ratio;
viewParams.bottomToBottom = bottomToBottom;
viewParams.topToTop = topToTop;
viewParams.topToBottom = topToBottom;
viewParams.endToEnd = ConstraintLayout.LayoutParams.PARENT_ID;
viewParams.startToStart = ConstraintLayout.LayoutParams.PARENT_ID;
viewParams.verticalBias = verticalBias;
viewParams.setMargins(Dimensions.dpToPx(left), Dimensions.dpToPx(top), Dimensions.dpToPx(right), Dimensions.dpToPx(bottom));
view.setLayoutParams(viewParams);
}
重要的是要确保以显示和不显示键盘时正确缩放的方式设置垂直偏置。
