EditText setError在BottomSheetDialog中不合适

Question

我EditText在调用时遇到错误指示器位置的问题editText.setError("...").

正如您在屏幕截图中看到的,我正在使用它BottomSheetDialog的EditText内部.当我显示错误指示符时,文本完全不合适.似乎对话框"认为"它是全屏的,而实际上并非如此.

这是我的对话框布局文件(phone_dialog.xml):

<android.support.constraint.ConstraintLayout 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="wrap_content"
                                             android:layout_weight="0"
                                             android:orientation="vertical">

    <TextView
        android:id="@+id/tvTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:gravity="center"
        android:padding="@dimen/padding_layout_normal"
        android:text="@string/dialog_title_edit_phone"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        />

    <EditText
        android:id="@+id/etPhone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:gravity="center"
        android:inputType="phone"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/tvTitle"/>


    <Button
        android:id="@+id/btnSavePhone"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="0dp"
        android:layout_marginRight="0dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/etPhone"/>

</android.support.constraint.ConstraintLayout>

我的Activity布局文件(activity_contacts.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rvContacts"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</LinearLayout>

这就是我显示对话框的方式Activity:

PhoneBottomDialog dialog = new PhoneBottomDialog(Context);
dialog.show();

这是我的PhoneBottomDialog班级:

public class PhoneBottomDialog extends BottomSheetDialog {

    public PhoneBottomDialog(Context context) {
        super(context);

        View view = getLayoutInflater().inflate(R.layout.phone_dialog, null);
        setContentView(view);

        // additional setup below this...
    }

    // ...
}

我没有在我的自定义内执行任何其他布局PhoneButtomDialog.将对话框的根布局更改为RelativeLayout或LinearLayout添加a ScrollView不会更改任何内容.它也不是设备或特定的Android版本相关问题,因为问题出现在我的所有测试设备上,范围从Android 5.0到7.1,它也发生在模拟器上.

有谁知道为什么会这样？

您可以使用TextInputLayout和内部定义Edit Text.

我在你的内部做了一些修改phone_dialog.xml.

phone_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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/bottom_sheet"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:layout_gravity="bottom"
    android:background="@android:color/holo_blue_light"
    android:padding="10dp"
    app:behavior_hideable="true"
    app:behavior_peekHeight="60dp"
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior">


    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <TextView
            android:id="@+id/tvTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="8dp"
            android:gravity="center"
            android:padding="10dp"
            android:text="dialog_title_edit_phone" />

        <android.support.design.widget.TextInputLayout
            android:id="@+id/inputPhone"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/TextInputLayoutLabel">

            <EditText
                android:id="@+id/etPhone"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Enter phone"
                android:imeOptions="actionDone"
                android:inputType="phone"
                android:maxLines="1"
                android:textSize="20sp" />

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


        <Button
            android:id="@+id/btnSavePhone"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/etPhone"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="8dp"
            android:text="Save" />

    </LinearLayout>

</FrameLayout>

在里面style.xml添加这个.

<style name="TextInputLayoutLabel" parent="Widget.Design.TextInputLayout">
        <!-- Hint color and label color in FALSE state -->
        <item name="android:textColorHint">@android:color/black</item>
        <item name="android:textSize">15sp</item>
        <!-- Label color in TRUE state and bar color FALSE and TRUE State -->
        <item name="colorAccent">@color/colorPrimary</item>
        <item name="colorControlNormal">@color/colorAccent</item>
        <item name="colorControlActivated">@color/colorAccent</item>
    </style>

PhoneBottomDialog.java

public class PhoneBottomDialog extends BottomSheetDialog {

    TextInputLayout inputPhone;
    EditText edtPhone;
    Button btnSave;

    public PhoneBottomDialog(Context context) {
        super(context);

        View view = getLayoutInflater().inflate(R.layout.phone_dialog, null);
        setContentView(view);

        // additional setup below this...

        inputPhone = (TextInputLayout) view.findViewById(R.id.inputPhone);

        edtPhone = (EditText) view.findViewById(R.id.etPhone);
        btnSave = (Button) view.findViewById(R.id.btnSavePhone);

        btnSave.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (!validatePhone())
                    return;
            }
        });

    }

    private boolean validatePhone() {
        if (edtPhone.getText().toString().isEmpty()) {
            inputPhone.setError("Please enter valid phone number with country code.");
            requestFocus(edtPhone);
            return false;
        } else {
            inputPhone.setErrorEnabled(false);
        }
        return true;
    }

    private void requestFocus(View view) {
        if (view.requestFocus()) {
            getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
        }
    }

    // ...
}

在里面Activity.

@SuppressLint("SetTextI18n")
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test24);
        mContext = this;

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

        PhoneBottomDialog dialog = new PhoneBottomDialog(mContext);
        dialog.show();
}

您可以在下面看到此输出.
