我正在使用一个TextInputEditText. 为此，我在单击相同的编辑文本时以编程方式设置可绘制对象。

默认情况下，编辑文本显示蓝色底线和提示颜色为蓝色，即我在主题中设置的强调色。

现在我在以编程方式设置drawable之后，我想将编辑文本显示为默认值。

我试图将drawable设置为null或背景资源为0，但这完全从编辑文本中删除了drawable并且底线消失了。

我应该怎么做才能让它恢复默认值？

设置drawable后看起来像这样。

后来drawable继续，但如果我点击edt_unit我试过 edt_Item_Name.setBackgroundResource(0);：所以底线消失了。

代码：

    containerLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            edt_Item_Name.setFocusable(false);
            edt_Item_Unit.setFocusable(false);

            linearLayoutRecycleView.setVisibility(View.GONE);
            linearLayoutUnits.setVisibility(View.GONE);
            textInput_Item_quantity.setVisibility(View.VISIBLE);
            textInput_Item_Unit.setVisibility(View.VISIBLE);
            textInput_Item_Unit.setBackgroundResource(0);
            textInput_Item_name.setBackgroundResource(0);

            edt_Item_Name.setText("");

            edt_Item_Unit.setHintTextColor(ContextCompat.getColor(SearchActivity.this,R.color.grey));

你也可以试试这个：

<EditText
    android:id="@+id/et"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:hint="Input your country"
    android:background="@drawable/edittext_bg"
    android:padding="10dp"
    />

现在为“edittext_bg”编写代码，您也可以根据自己的选择进行自定义：

res/drawable/edittext_bg.xml

    <?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <!-- Draw a 2dp width border around shape -->
            <stroke
                android:color="#ff1e0c"
                android:width="2dp"
                />
        </shape>
    </item>
    <!-- Overlap the left, top and right border using background color  -->
    <item
        android:bottom="2dp"
        >
        <shape android:shape="rectangle">
            <solid android:color="#fffbce"/>
        </shape>
    </item>
</layer-list>

但是你为什么要对它应用一个drawable呢？无论如何，您可以在其中包含您的编辑文本的view下方添加。textInput layout并设置 edt_Item_Name.setBackgroundResource(0);

你的 xml 看起来像这样。

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

<EditText
    ....

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



<View
        android:layout_width="match_parent"
        android:layout_height="2dp"
        android:background="@color/your_color"
        ></View>

更新

    <android.support.design.widget.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="40dp"
            android:id="@+id/editTextItemName"
            android:layout_gravity="center_horizontal|center_vertical"
            android:hint="@string/item_name"
            android:focusable="false"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginBottom="07dp"
            android:textSize="14sp"
            android:textStyle="bold">

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

在此处添加视图

                   <View
                        android:layout_width="match_parent"
                        android:layout_height="2dp"
                        android:background="@color/your_color">
                   </View>
        </LinearLayout>

答案 2

TextInputLayout textInputLayout =(TextInputLayout)findViewById(R.id.input_layout_item_name);

textInputLayout.setBackgroundResource(R.drawable.your_bg);

然后点击另一个编辑文本集

textInputLayout.setBackgroundResource(0);
