如果在编辑文本上单击两次，则Drawable会更改
我有两个编辑文本视图，我在其中添加了两个drawable。一个是edit_text_bottom_line，另一个是edit_drawable。
现在我想在编辑文本输入上显示edit_text_bottom_line drawable。所以我可以看到这样的布局：
这很有用。现在再次我想显示另一个drawable当我们再次点击编辑文本输入和浮动提示时，它应该看起来像这样：
这也有效。但是现在，如果我再次点击编辑文本视图，那么它会更改布局edit_text_bottom_line drawable如下所示：
我希望在用户开始输入时显示蓝色可绘制，直到他在编辑文本视图上以及编辑文本被聚焦之后。
如何确定编辑文本是否有焦点？我尝试使用onFocusChangeListener，如果编辑文本是聚焦的，则显示蓝色可绘制但下次单击时会出现偏差。

或者更确切地说应用了两个布局，我在主题中将强调色设置为蓝色，因此默认情况下编辑文本如果聚焦得很好就会采用蓝色，但是当我更改灰线的可绘制之后，怎么能我转到编辑文本的默认蓝线？
请帮助，谢谢..

只需做一件事就可以使你的输入文字布局如下：
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:hintTextAppearance="@android:style/TextAppearance.Small">
<EditText
android:id="@+id/user_name"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:padding="@dimen/_10sdp"
android:hint="@string/full_name"
android:inputType="text"
android:background="@android:color/transparent"
/>
</android.support.design.widget.TextInputLayout>
它会解决你的问题。

使用以下命令更改xml TextInputLayout和TextInputEditText：
<android.support.design.widget.TextInputLayout
android:id="@+id/input_layout_item_quantity"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="02dp"
android:textColorHint="@color/grey">
<android.support.design.widget.TextInputEditText
android:id="@+id/editTextItemQuantity"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="05dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:hint="@string/quantity"
android:imeOptions="actionDone"
android:inputType="number"
android:textColor="@color/lighttextcolor"
android:textSize="14sp"
android:textStyle="bold"
android:theme="@style/style_edittext_color_control"/>
</android.support.design.widget.TextInputLayout>
在res/values/styles.xml添加此内容：
<style name="style_edittext_color_control" parent="Theme.AppCompat.Light">
<item name="colorControlNormal">@color/grey</item>
<item name="colorControlActivated">@color/blue</item>
</style>
希望这会给你正确的结果。
