BottomSheetDialogFragment

Question

我试图在里面创建一个带有TextInputLayout的BottomSheetDialogFragment。我将此BottomSheet设置为adjustResize以防止键盘覆盖TextInputLayout。问题是我在不同的Android版本中获得了不同的行为。

这是布局：

<android.support.constraint.ConstraintLayout 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:id="@+id/linearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.design.widget.TextInputLayout
    android:id="@+id/textInputLayout"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginBottom="16dp"
    android:layout_marginEnd="16dp"
    android:layout_marginStart="16dp"
    android:layout_marginTop="16dp"
    android:background="@android:color/darker_gray"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="0.0">

    <android.support.design.widget.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="hint" />
</android.support.design.widget.TextInputLayout>

这是BottomSheetDialogFragment：

public class TestFragment extends BottomSheetDialogFragment {

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

    return inflater.inflate(R.layout.fragment_test, container, true);
}

}

这是理想的结果：

这是我在某些版本中获得的结果：

我得到了所需的结果：

• Galaxy S6 with Android 7.0
• ＆lt; = Android 5.1
的模拟器

没有预期的结果：

• Nexus 5 with Android 7.1.2（LineageOS 14.1）
• 具有=＆gt;的模拟器Android 6.0

有谁知道为什么会发生这种情况或如何解决它？

提前致谢!!!

干杯。

此问题浪费了我的1小时。不使用ADJUST_RESIZE。

只需将您的布局包装在NestedScrollView 。

中

没有更多。没有。问题解决了。

这是XML

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView 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/linearLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.TextInputLayout
            android:id="@+id/textInputLayout"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginBottom="16dp"
            android:layout_marginEnd="16dp"
            android:layout_marginStart="16dp"
            android:layout_marginTop="16dp"
            android:background="@android:color/darker_gray"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintVertical_bias="0.0">

            <android.support.design.widget.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="hint" />
        </android.support.design.widget.TextInputLayout>

    </android.support.constraint.ConstraintLayout>

</android.support.v4.widget.NestedScrollView>

这是源代码

public class DemoFragment extends BottomSheetDialogFragment {

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    private BottomSheetBehavior.BottomSheetCallback mBottomSheetBehaviorCallback = new BottomSheetBehavior.BottomSheetCallback() {

        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            if (newState == BottomSheetBehavior.STATE_HIDDEN) {
                dismiss();
            }
        }

        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset) {
        }
    };

    @Override
    public void setupDialog(Dialog dialog, int style) {
        super.setupDialog(dialog, style);
        View contentView = View.inflate(getContext(), R.layout.fragment_layout, null);
        dialog.setContentView(contentView);

        CoordinatorLayout.LayoutParams layoutParams =
                (CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams();
        CoordinatorLayout.Behavior behavior = layoutParams.getBehavior();
        if (behavior != null && behavior instanceof BottomSheetBehavior) {
            ((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback);
        }
    }

}
