如何在android中更改TextInputLayout顏色？

Question

嗨，我是新的Android和我的應用程序，我使用TextInputLayout字段。

我設置了EditText邊框顏色，我不想設置編輯文本背景顏色，但根據我的下面代碼，當我點擊“SIGN UP”按鈕時，edittext背景顏色顯示為紅色。

我們怎樣才能改變這種背景顏色？

edittext_background： -

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <solid android:color="@android:color/white" />

    <stroke
        android:width="1dip"
        android:color="@android:color/holo_purple" />

    <padding android:left="5dp"
        android:top="5dp"
        android:right="5dp"
        android:bottom="5dp"/>

</shape>

樣式： -

 <style name="TextAppearance.App.TextInputLayout" parent="@android:style/TextAppearance">
        <item name="android:textColor">@color/splahbgcolor</item>
        <item name="android:textSize">14sp</item>
    </style>

main.xml中： -

<LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="?attr/actionBarSize"
        android:orientation="vertical"
        android:paddingLeft="20dp"
        android:paddingRight="20dp"
        android:paddingTop="60dp">

        <android.support.design.widget.TextInputLayout
            android:id="@+id/input_layout_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:hintTextAppearance="@style/TextAppearance.App.TextInputLayout">

            <android.support.v7.widget.AppCompatEditText
                android:id="@+id/input_name"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:singleLine="true"
                android:background="@drawable/edittext_background"
                android:ems="10"
                android:inputType="textEmailAddress"
                android:padding="8dp"
                android:textColor="@color/splahbgcolor"
                android:hint="@string/hint_name" />

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

Answer 1

使用主題而不是hintTextAppearance

 <android.support.design.widget.TextInputLayout
            android:id="@+id/input_layout_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
           app:hintTextAppearance="@color/colorPrimary"
            android:theme="@style/TextAppearance>

你的風格

 <style name="TextAppearance" parent="@android:style/TextAppearance">
        <item name="android:textColor">@color/splahbgcolor</item>
        <item name="android:textColorHint">@color/splahbgcolor</item>
    </style>

Answer 2

TL; DR版本：
調用inputName.setBackgroundResource(R.drawable.edittext_background); 每次調用inputLayoutName.setError(getString(R.string.err_msg_name));

更長的版本：
發生這種情況是因為當您在TextInputlayout內部（在TextInputLayout的代碼中）調用setError（errormsg）時 ，此方法在設置Errorview調用以下方法：
updateEditTextBackground();

在TextInputLayout類的updateEditTextBackground()方法內，使用以下行更改editText的背景顏色：

if (mErrorShown && mErrorView != null) {
        // Set a color filter of the error color
        editTextBackground.setColorFilter(
                AppCompatDrawableManager.getPorterDuffColorFilter(
                        mErrorView.getCurrentTextColor(), PorterDuff.Mode.SRC_IN));
    }

因此，您的Edittext的背景顏色變為紅色（這是從Errorview's默認textAppearance樣式中從框架中Errorview's ）。

在您的情況下，只有可能的解決方法是在if子句中的所有setError方法之后添加以下行：

inputName.setBackgroundResource(R.drawable.edittext_background);

validateName()方法：

   private boolean validateName() {

    if (inputName.getText().toString().trim().isEmpty()) {
        inputLayoutName.setError(getString(R.string.err_msg_name));
        inputName.setBackgroundResource(R.drawable.edittext_background);
        requestFocus(inputName);
        return false;

    } else {
        inputLayoutName.setErrorEnabled(false);
    }

    return true;
}

可能只是解決您的問題。
不確定這是否是處理自定義Edittext背景情況的適當方法。
