Question

<android.support.design.widget.TextInputLayout
            android:id="@+id/input_layout_enter_first_name"
            android:layout_width="@dimen/btn_width"
            android:layout_height="@dimen/editText_height"
            android:layout_marginTop="@dimen/layout_margin_top_20"
            android:background="@drawable/transperent_bg"
            android:textColorHint="@color/white"
              >

            <EditText
                android:id="@+id/enter_first_name"
                android:layout_width="match_parent"
                android:layout_height="40dp"
                android:layout_marginLeft="@dimen/layout_margin_left_5"
                android:layout_marginTop="@dimen/layout_margin_top_1"
                android:background="@color/transperent"
                android:backgroundTint="@color/white"
                android:inputType="textEmailAddress"
                android:maxLines="1"
                android:hint="@string/enter_first_name"
                android:textColorHint="@color/white"
                android:textColor="@color/white"
                android:textSize="@dimen/textsize_12" />
        </android.support.design.widget.TextInputLayout>



TextInputLayout input_layout_enter_first_name = (TextInputLayout) findViewById(R.id.input_layout_enter_first_name);

input_layout_enter_first_name.setHint（Html.fromHtml（“Required !!!”））;

实际上它只是动态更改文本但无法将颜色更改为RED。

Answer 1

您可以从TextInputLayout设置style文字提示颜色，如下所示：

TextInputLayout til = (TextInputLayout) view.findViewById(R.id.input_layout_enter_first_name);
til.setHintTextAppearance(R.style.One);

风格：

 <style name="One">
    <item name="android:textColor">@color/Red</item>
</style>

<style name="Two">
    <item name="android:textColor">@color/color_primary</item>
</style>

设置所需的颜色，并在任何您喜欢的地方之间切换

我想从Java代码动态地将TextInputLayout的提示颜色从白色更改为红色。
