问题
I have problems with the translucent actionbar/navbar in the new Android KitKat (4.4) and the windowSoftInputMode=\"adjustResize\".
Normaly changing the InputMode to adjustResize, the app should resize itself when keyboard is shown... but here it won\'t! If I delete the lines for the transparent effect, the resize is working.
So if the keyboard is visible, my ListView is under it and I can\'t access the last few items. (Only by hiding the keyboard manually)
AndroidManifest.xml

Anyone ideas for fixing this?
回答1:
You are missing the following property:
android:fitsSystemWindows="true"
in the root RelativeLayout of the fragment .xml layout.
Update:
Last year there was an interesting talk by Chris Bane that explains in good detail how this works:

There's a related bug report here. I've found a workaround that, from limited testing, seems to do the trick with no repercussions. Add a custom implementation of your root ViewGroup (I almost always am using FrameLayout, so this is what I've tested with) with the logic below. Then, use this custom layout in place of your root layout, and ensure you set android:fitsSystemWindows="true". You can then just call getInsets() any time after layout (e.g. add an OnPreDrawListener) to adjust the rest of your layout to account for the system insets, if desired.

import android.graphics.Rect;

mInsets[2] = insets.right;
insets.left = 0;
insets.top = 0;
insets.right = 0;
}
return super.fitSystemWindows(insets);
}
}
Since fitSystemWindows was deprecated, please refer to the answer below to complete the workaround.
回答3:
@kcoppock answer is really helpful, but fitSystemWindows was deprecated in API level 20
So since API 20 (KITKAT_WATCH) you should override 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;
}
}
回答4:
This worked for me to have translucent status bar and adjustResize in fragment:
Make a custom RelativeLayout as @Victor91 and @kcoppock said.
Use CustomRelativeLayout as parent layout for your fragment.
Declare theme with android:windowTranslucentStatus = true
The container Activity must be declared in Manifest with android:windowSoftInputMode="adjustResize" and use the declared theme
Please Use fitsSystemWindows on fragment root layout!
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; } } }
Then in xml,
<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>
回答5:
If you want to customize the insets and you are targeting API level >=21 you can accomplish this without having to create a custom view group. By just setting fitsSystemWindows padding will be applied to your container view by default, which you may not want.
The version checks are built into this method and only devices >= 21 will execute the code inside the lambda. Kotlin example:
ViewCompat.setOnApplyWindowInsetsListener(container) { view, insets ->
insets.replaceSystemWindowInsets(0, 0, 0, insets.systemWindowInsetBottom).apply {
ViewCompat.onApplyWindowInsets(view, this)
}
}
Make sure your layout still sets the fitsSystemWindows flag otherwise the window insets listener will not be called.
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
/>

I had the same problem, My Activity had a ScrollView as root view and with translucent statusbar activated it didn't resize correctly when keyboard showed... and conseguently the screen didn't scrolled hiding the input views.
Solution: Moved everything (layout and activity logic) inside a new Fragment. Then changed the Activity to only include this Fragment. Now everything works as expected!
This is the layout of the activity:
<?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" />
回答7:
Based on Joseph Johnson's workaround in Android How to adjust layout in Full Screen Mode when softkeyboard is visible
call this in onCreate() after setContentView() in your activity.
AndroidBug5497Workaround.assistActivity(this);
a litte different from original replace return (r.bottom - r.top); with return r.bottom; in computeUsableHeight()
for some reason, i must set my activity fitsSystemWindows attribute to false.
this workaround saved me. it's works well for me. hope can help you.
the implementation class is:
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;
}
}

AndroidBug5497Workaround.java take care memory leak. need below code
getViewTreeObserver().removeOnGlobalLayoutListener(listener);
My sample using RxJava that automatically call removeOnGlobalLayoutListener() when onPause() in Activity's lifecycle
public class MyActivity extends RxAppCompatActivity {
// ...
protected void onStart(){
super.onStart();
TRSoftKeyboardVisibility
.changes(this) // activity
.compose(this.<TRSoftKeyboardVisibility.ChangeEvent>bindUntilEvent(ActivityEvent.PAUSE))
.subscribe(keyboardEvent -> {
FrameLayout content = (FrameLayout) findViewById(android.R.id.content);
View firstChildView = content.getChildAt(0);
firstChildView.getLayoutParams().height = keyboardEvent.viewHeight();
firstChildView.requestLayout();
// keyboardEvent.isVisible = keyboard visible or not
// keyboardEvent.keyboardHeight = keyboard height
// keyboardEvent.viewHeight = fullWindowHeight - keyboardHeight
});
//...

I had like a problem.
I set windowDrawsSystemBarBackgrounds to 'true' and my app should show under status bar.
It's my activity theme.
<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>
and I got help from jianshu's blog. you can read code but text like me. I add few code more.
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[2] = insets.right;
insets.left = 0;
insets.top = 0;
insets.right = 0;
}
return super.fitSystemWindows(insets);
}
}
This is my fragment layout.

android:background="@color/white">
<!-- your xml code -->
</ZeroInsetsFrameLayout>
I want it to be helpful to you. good luck!
回答10:
The best practice allows user scroll content when the keyboard is shown.
So to add this functionality you need put your root layout inside the ScrollView and use windowSoftInputMode="adjustResize" activity method.
But if you want to use this functionality with <item name="android:windowTranslucentStatus">true</item>
flag on Android 5 content won't be scrollable and will overlaps with keyboard.
To solve this issue check this answer
回答11:
It shouldn't work with the translucent status bar; that setting forces the window into fullscreen mode which does not work with adjustResize.
You can either use adjustPan or use the fitsSystemWindows properties. I would suggest reading about the feature though, it has significant side effects:

- After I had researched on all forum. thoese ways can not help find point out. Lucky when i tried doing this way. It helps me resolved problem
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>
Activity
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView("Your Activity");
setAdjustScreen();
}
Created Func
protected void setAdjustScreen(){
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
/*android:windowSoftInputMode="adjustPan|adjustResize"*/
}
Finally adding some lines to your mainifest
<activity
android:name="Your Activity"
android:windowSoftInputMode="adjustPan|adjustResize"
android:screenOrientation="portrait"></activity>
