所以我有一个带有 ListView 按钮的自定义列表项。按下时,按钮显示备用可绘制对象以向用户显示反馈。但是,当我单击该行时,每个按钮都显示为按下状态,就好像我单击了它们一样。
如何保持按钮显示其原始状态而不是 state_pressed?
布局/列表项:
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="horizontal"
android:paddingBottom="10dp"
android:paddingTop="10dp"
android:descendantFocusability="blocksDescendants" >
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:gravity="center_vertical|left" >
<TextView
android:id="@+id/txtMain"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceLarge"
style="@style/PrimaryText" />
<TextView
android:id="@+id/txtSub"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceLarge"
style="@style/SecondaryText" />
</LinearLayout>
<ImageButton
android:id="@+id/imbResponse"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@null"
android:focusable="false"
android:duplicateParentState="false"
android:src="@drawable/response_btn"
android:contentDescription="@string/response"
android:layout_marginLeft="10dp"
android:layout_marginTop="5dp"
android:layout_marginRight="10dp"
android:layout_marginBottom="5dp" />
</LinearLayout>
可绘制/response_btn.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_focused="true" android:drawable="@drawable/res_m" />
<item android:state_pressed="true" android:drawable="@drawable/res_m" />
<item android:state_focused="false" android:state_pressed="false" android:drawable="@drawable/res_alt_m" />
</selector>
我试图删除 state_focused 和 state_pressed,state_focused。按钮似乎从其父级获取 state_pressed 。
