android中EditText的值键入初始值后更改

Question

用户开始输入EditText后，值会自动更改。值会自动更改为初始值。 请帮助我，导致此问题的原因

此布局用于适配器布局，完整的布局文件和适配器代码如下所示，这是引起问题的EditTextbox部分

               <LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_weight="1"
                    android:orientation="horizontal"
                    android:weightSum="2">
              <TextView
                    style="@style/booking_heading"
                    android:layout_width="0dp"
                    android:layout_height="match_parent"
                    android:text="Enter Amount" />
                <EditText
                    android:layout_width="0dp"
                    android:editable="true"
                    android:inputType="number"
                    android:layout_weight="1"
                    android:background="#fff"
                    android:padding="8dp"
                    android:text="00"
                    android:layout_height="match_parent"
                    android:id="@+id/booking_price" />
               </LinearLayout>
