TextInputLayout error alignment issue with AppComp

2019-05-14 15:04发布

问题:

I am using an app which displays a drop down Spinner with an EditText as a child of TextInputLayout next to it.

When an underlined error is shown under the TextInputLayout, then the EditText will go up, and alignment will miss !!

See my screenshot please:

What I am trying to do is:

Here is my xml code:

<LinearLayout
    android:layout_width="@dimen/edittext_width"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="bottom">

    <android.support.v7.widget.AppCompatSpinner
        android:id="@+id/spinner_countries"
        style="@style/Widget.AppCompat.Spinner.Underlined"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="30"
        android:layout_gravity="start"
        android:spinnerMode="dialog" />

    <android.support.design.widget.TextInputLayout
        android:id="@+id/input_layout_mobile"
        style="@style/TextInputLayoutTheme"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="70">

        <com.cashu.app.ui.widgets.CustomEditText
            android:id="@+id/et_fragment_register_step_one_mobile"
            android:layout_width="@dimen/edittext_mobile_num_width"
            android:layout_height="wrap_content"
            android:ems="12"
            android:gravity="center_vertical"
            android:layout_gravity="start"
            android:hint="@string/mobile_hint"
            android:inputType="number"
            android:textSize="@dimen/font_size_normal" />
    </android.support.design.widget.TextInputLayout>

</LinearLayout>

Here is my TextInputLayout theme:

<!-- TextInputLayout Style -->
<style name="TextInputLayoutTheme" parent="Widget.Design.TextInputLayout">
    <item name="android:gravity">center</item>
    <item name="android:textColor">@color/white</item>
    <item name="android:textColorHint">@color/colorControlActivated</item>
    <item name="errorTextAppearance">@style/AppTheme.TextErrorAppearance</item>
    <item name="counterTextAppearance">@style/TextAppearance.Design.Counter</item>
    <item name="counterOverflowTextAppearance">@style/TextAppearance.Design.Counter.Overflow</item>
</style>

I tried searching for many keywords, terms and methods but unfortunately with no luck.

I would appreciate if anyone has a hack for this issue.

回答1:

Add app:errorEnabled="true" in TextInputLayout.

This will leave space for error even if error is not displayed. This will consume more space but will help you to maintain alignment.

Make your TextInputLayout as below.

 <android.support.design.widget.TextInputLayout
    android:id="@+id/input_layout_mobile"
    style="@style/TextInputLayoutTheme"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="70"
    app:errorEnabled="true">

Later in java:

  1. To set error text use

    textInputLayout.setError("Email can not be blank");
    
  2. To remove error text and set view as normal

    textInputLayout.setError("");
    

*Note that the use of textInputLayout.setErrorEnable(false) to remove the error will take out entire text view of error from the textInputLayout which will disturb your alignment.

I figured out my problem, I set margin to my AppCompatSpinner and set top gravity to it with specific hight.

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="bottom"
        android:orientation="horizontal">

        <android.support.v7.widget.AppCompatSpinner
            android:id="@+id/spinner_countries"
            style="@style/Widget.AppCompat.Spinner.Underlined"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginBottom="26dp"
            android:layout_weight="30"
            android:spinnerMode="dialog" />

        <android.support.design.widget.TextInputLayout
            android:id="@+id/input_layout_mobile"
            style="@style/TextInputLayoutTheme"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="70"
            app:errorEnabled="true">

            <com.cashu.app.ui.widgets.CustomEditText
                android:id="@+id/et_mobile"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="start"
                android:ems="12"
                android:gravity="center_vertical"
                android:hint="@string/mobile_hint"
                android:inputType="number"
                android:textSize="@dimen/font_size_normal" />
        </android.support.design.widget.TextInputLayout>

</LinearLayout>

[EDIT]

When my TextInputLayout has an error, I remove it by adding the following lines:

myTextInputLayout.setErrorEnabled(false);
myTextInputLayout.setErrorEnabled(true);
myTextInputLayout.setError(" ");

Why?

  • This line: myTextInputLayout.setErrorEnabled(false); will clear the error from the TextInputLayout

  • This line: myTextInputLayout.setErrorEnabled(true); will enable error for the TextInputLayout again

  • This line: myTextInputLayout.setError(" "); will prevent layout alignment disruption.

Problem now is solved.

try this,

 <LinearLayout
    android:layout_width="300dp"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="bottom">

    <android.support.v7.widget.AppCompatSpinner
        android:id="@+id/spinner_countries"
        style="@style/Widget.AppCompat.Spinner.Underlined"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="30"
        android:spinnerMode="dialog" />

    <android.support.design.widget.TextInputLayout
        android:id="@+id/input_layout_mobile"
        style="@style/TextInputLayoutTheme"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="70">

        <EditText
            android:id="@+id/et_fragment_register_step_one_mobile"
            android:layout_width="200dp"
            android:layout_height="wrap_content"
            android:ems="12"
            android:gravity="center_vertical"
            android:layout_gravity="start"
            android:hint="Mobile No."
            android:inputType="number"
            android:textSize="20sp" />
    </android.support.design.widget.TextInputLayout>
