键盘隐藏 BottomSheetDialogFragment

Question

键盘下方有更多字段。这发生在我更新支持库时。我知道它是 Kotlin，但它看起来几乎和 java 一样。我该如何解决这个问题？

这是它的样子：

我的代码：

class ProjectsEditBottomSheetFragment(val privateID: String,
                                  val publicID: String) : BottomSheetDialogFragment() {



private val mBottomSheetBehaviorCallback = object : BottomSheetBehavior.BottomSheetCallback() {
    override fun onStateChanged(bottomSheet: View, newState: Int) {
        if (newState == BottomSheetBehavior.STATE_HIDDEN) {
            dismiss()
        }

    }


    override fun onSlide(bottomSheet: View, slideOffset: Float) {
        if (slideOffset < -0.15f) {
            dismiss()
        }
    }
}


override fun setupDialog(dialog: Dialog, style: Int) {
    super.setupDialog(dialog, style)
    val view = View.inflate(context, R.layout.projects_edit_sheet, null)
    dialog.setContentView(view)

    dialog.window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)


    val params = (view.parent as View).layoutParams as CoordinatorLayout.LayoutParams
    val behavior = params.behavior

    if (behavior != null && behavior is BottomSheetBehavior<*>) {
        behavior.setBottomSheetCallback(mBottomSheetBehaviorCallback)
    }


    // Get and set values
    val realm = Realm.getDefaultInstance()
    val realmObject = realm.where(ProjectsRealmObject::class.java)
            .equalTo("privateID", privateID)
            .findFirst()




    realm.beginTransaction()
    view.title_input.text = SpannableStringBuilder(realmObject.title)
    view.description_input.text = SpannableStringBuilder(realmObject.description)
    view.public_checkbox.isChecked = realmObject.isPublic
    realm.commitTransaction()


    // Keyboard
    view.title_input.onFocusChangeListener = View.OnFocusChangeListener { _, hasFocus ->
        if (hasFocus) {
            (context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager).showSoftInput(view.title_input, InputMethodManager.SHOW_FORCED)
        } else {
            (context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager).hideSoftInputFromWindow(view.title_input.windowToken, 0)
        }
    }

    view.description_input.onFocusChangeListener = View.OnFocusChangeListener { _, hasFocus ->
        if (hasFocus) {
            (context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager).showSoftInput(view.description_input, InputMethodManager.SHOW_FORCED)
        } else {
            (context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager).hideSoftInputFromWindow(view.description_input.windowToken, 0)
        }
    }


    // Click listners
    view.public_layout.setOnClickListener { view.public_checkbox.toggle() }

    view.cancel.setOnClickListener {
        view?.hideKeyboard()
        dismiss()
    }

    view.save.setOnClickListener {
        view?.hideKeyboard()
        // Save to realm
        realm.beginTransaction()
        realmObject.title = if (view.title_input.text.toString() == "") getString(R.string.unnamed) else view.title_input.text.toString()
        realmObject.description = view.description_input.text.toString()
        realmObject.isPublic = view.public_checkbox.isChecked
        realmObject.synced = false
        realmObject.updatedRealm = TimeUnit.MILLISECONDS.toSeconds(System.currentTimeMillis()).toString() + ""
        realm.commitTransaction()

        ProjectsSync(context)

        toast("Sparat")

        dismiss()
    }

  }
}

Answer 1

将此添加到您的样式中

<style name="DialogStyle">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="colorPrimaryDark">@android:color/transparent</item>
</style>

然后在您底部 sheet 对话框的 onCreate() 添加

setStyle(DialogFragment.STYLE_NO_FRAME, R.style.DialogStyle);

也不要忘记添加到对话框设置 Dialog() 方法

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

Answer 2

这对我有用

public class CustomBottomSheetDialogFragment extends BottomSheetDialogFragment 
{
 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle 
    savedInstanceState) {
View v = inflater.inflate(R.layout.content_dialog_bottom_sheet, container, false);


getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
    return v;
 }

Answer 3

我找到了 27 api 的解决方案。因此，即使 SOFT_INPUT_ADJUST_RESIZE 键盘隐藏视图的原因是为对话框设置了 windowIsFloating。

我发现最方便的更改方式是创建样式：

<style name="DialogStyle" parent="Theme.Design.Light.BottomSheetDialog">
    <item name="android:windowIsFloating">false</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:windowSoftInputMode">adjustResize</item>
</style>

并在 BottomSheetDialogFragment 的 onCreate 方法中进行设置：

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setStyle(DialogFragment.STYLE_NORMAL, R.style.DialogStyle)
}

这是它在我的设备上的样子：

可以使用下一个class:

import android.graphics.Rect; 
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.design.widget.BottomSheetBehavior;
import android.support.design.widget.BottomSheetDialog;
import android.support.design.widget.BottomSheetDialogFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;

public class TestBottomSheetDialog extends BottomSheetDialogFragment {

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View fragmentView = LayoutInflater.from(getContext()).inflate(R.layout.fragment_bottom_sheet, container, false);
        if (getDialog().getWindow() != null) {
           getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
        }
        if (getActivity() != null) {
            View decorView = getActivity().getWindow().getDecorView();
            decorView.getViewTreeObserver().addOnGlobalLayoutListener(() -> {
                Rect displayFrame = new Rect();
                decorView.getWindowVisibleDisplayFrame(displayFrame);
                int height = decorView.getContext().getResources().getDisplayMetrics().heightPixels;
                int heightDifference = height - displayFrame.bottom;
                if (heightDifference != 0) {
                    if (fragmentView.getPaddingBottom() != heightDifference) {
                        fragmentView.setPadding(0, 0, 0, heightDifference);
                    }
                } else {
                    if (fragmentView.getPaddingBottom() != 0) {
                        fragmentView.setPadding(0, 0, 0, 0);
                    }
                }
            });
        }
        getDialog().setOnShowListener(dialog -> {
            BottomSheetDialog d = (BottomSheetDialog) dialog;
            View bottomSheetInternal = d.findViewById(android.support.design.R.id.design_bottom_sheet);
            if (bottomSheetInternal == null) return;
             BottomSheetBehavior.from(bottomSheetInternal).setState(BottomSheetBehavior.STATE_EXPANDED);
        });
        return fragmentView;
    }
}

Answer 5

我尝试了该主题中的所有答案，但没有任何帮助。我浏览了许多网站，发现只有一种解决方案适合我。

 override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    val dialog = super.onCreateDialog(savedInstanceState)

    dialog.window?.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)
    dialog.setOnShowListener {
        Handler().post {
            val bottomSheet = (dialog as? BottomSheetDialog)?.findViewById<View>(R.id.design_bottom_sheet) as? FrameLayout
            bottomSheet?.let {
                BottomSheetBehavior.from(it).state = BottomSheetBehavior.STATE_EXPANDED
            }
        }
    }

    return dialog
}

Answer 6

在我花了 5 个小时没有运气之后，这个解决方案对我有用：

第 1 步：

将此代码添加到您的 styles.xml（位于 res\values 文件夹中）

<style name="CustomizedBottomDialogStyle">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:backgroundDimAmount">0.7</item>
    <item name="android:windowIsFloating">false</item>
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:windowSoftInputMode">adjustResize</item>
    <item name="android:background">@android:color/transparent</item>
</style>

这里关键是设置android:windowIsFloating -> false,如果是 true 您的代码将无法运行！因此，我使用 android:backgroundDimEnabled 和 android:backgroundDimAmount 来使背景看起来透明并带有漂亮的叠加层。

第 2 步：

编写此函数以编程方式调整它（注意它不是可选的，您需要执行步骤#1 和#2）：

private fun showDialog() {

    BottomSheetDialog(requireActivity(), R.style.CustomizedBottomDialogStyle).apply {

        window?.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)

        setOnShowListener {
            Handler().post {
                val bottomSheet = findViewById<View>(R.id.design_bottom_sheet) as? FrameLayout
                bottomSheet?.let {
                    BottomSheetBehavior.from(it).state = STATE_EXPANDED
                }
            }
        }

        setContentView(R.layout.dialog_layout)

        // Your code goes here....

        show()
    }
}
