GridView的项目列表选择在Android的不工作的多个项目 [英] GridView item list selector for multiple items not working in Android
问题描述
我想如图片所示长preSS绘制选择。当我做长preSS上的一个项目，该CAB菜单被激活。但列表选择指标后，点击一次去关闭。我想该列表选择活跃，直到CAB菜单允许多重选择活跃。如果我做双击的颜色应该切换。这code工作，当我点击它闪烁。任何一个面临着类似的事情？是否有黑客把这个功能呢？
I want to draw selector on long press as shown in the picture. When I do long press on one item, the CAB menu is activated. But the list selector indicator goes off once after clicking. I want that list selectors to be active till the CAB menu is active for allowing multiple selection. And the color should toggle if I do double tap. This code works as a flicker when I click on it. Any one faced similar thing? Is there a hack to bring this functionality?
的GridView有多个选择：
Gridview with multiple selection:
在我的OnCreate的GridView setchoice：
GridView setchoice in my OnCreate:
gridView.setChoiceMode(GridView.CHOICE_MODE_MULTIPLE_MODAL);
gridView.setMultiChoiceModeListener(new MultiChoiceModeListener());
这是工作的罚款：
gridView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
ImageView iv = (ImageView) v
.findViewById(R.id.imageview2);
ViewGroup gridChild = (ViewGroup) gridView
.getChildAt(position);
ViewGroup gridGrandChild = (ViewGroup) gridChild
.getChildAt(0);
ViewGroup gridGreatGrandChild = (ViewGroup) gridGrandChild
.getChildAt(0);
int childSize = gridGreatGrandChild.getChildCount();
if (iv.getId() == gridGreatGrandChild.getChildAt(1)
.getId()) {
if (iv.getVisibility() == 4)
iv.setVisibility(View.VISIBLE);
else
iv.setVisibility(View.INVISIBLE);
}
}});
我想实现的MultiChoiceModeListener（）类中同一code中的CAB菜单被激活后。复制同样的code里面
I am trying to implement the same code inside the MultiChoiceModeListener() class after the CAB menu is activated. Copied the same code inside
public void onItemCheckedStateChanged(ActionMode mode, int position,
long id, boolean checked) {
}
方法。但我无法访问里面的ViewGroup元素。但我能够访问GridView的全部。但不是网格内的各个子。
method. But I am unable to access the elements inside the viewgroup. But I am able to access the GridView in whole. But not the individual child inside the Grid.
下面是我的GridView布局：
Here is my gridview layout:
<GridView
android:id="@+id/grid_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:columnWidth="190dp"
android:drawSelectorOnTop="true"
android:choiceMode="multipleChoice"
android:horizontalSpacing="3dp"
android:listSelector="@drawable/list_selector"
android:numColumns="auto_fit"
android:paddingRight="4dp"
android:stretchMode="spacingWidthUniform"
android:verticalSpacing="3dp" >
</GridView>
在GridView每个项目都建成用这个布局：
Each item in the GridView is constructed with this layout:
<FrameLayout
android:id="@+id/frameLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<RelativeLayout
android:id="@+id/relativelayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="@+id/imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</ImageView>
<ImageView
android:id="@+id/imageview2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/imageview"
android:layout_alignLeft="@+id/imageview"
android:layout_alignRight="@+id/imageview"
android:layout_alignTop="@+id/imageview"
android:visibility="invisible"
android:background="#76f9a49c"
>
</ImageView>
</RelativeLayout>
<ImageView
android:id="@+id/tagimage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|right"
android:layout_marginRight="-4dp"
android:src="@drawable/tag"
android:visibility="invisible" />
<ImageView
android:id="@+id/countimage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_marginBottom="8dp"
android:layout_marginRight="5dp"
android:src="@drawable/dealcount_overlay"
android:visibility="invisible" />
<TextView
android:id="@+id/count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_marginBottom="11dp"
android:layout_marginRight="24dp"
android:text="100"
android:textColor="#fff"
android:visibility="invisible" >
</TextView>
<ProgressBar
android:id="@+id/progressbar"
style="@android:style/Widget.ProgressBar.Small"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_gravity="center"
android:visibility="visible" />
</FrameLayout>
<TextView
android:id="@+id/textView_nodata"
android:layout_width="wrap_content"
android:layout_height="150dp"
android:layout_below="@+id/frameLayout1"
android:layout_centerHorizontal="true"
android:text="No data available. Try different query!"
android:textAppearance="?android:attr/textAppearanceLarge"
android:visibility="gone" />
</RelativeLayout>
下面是我的list_selector.xml：
Here is my list_selector.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/gridviewlistselector" android:state_focused="true" android:state_pressed="false"/>
<item android:state_focused="true"><shape>
<solid android:color="#66000000" />
</shape></item>
<item android:state_selected="true"><shape>
<solid android:color="#66000000" />
</shape></item>
<item android:state_pressed="true"><shape>
<solid android:color="#66000000" />
</shape></item>
<item android:state_enabled="false" android:state_focused="true"><shape>
<solid android:color="#66000000" />
</shape></item>
</selector>
我如何能实现的功能？我卡住这个。我试着选择器的各种组合。但似乎没有为我工作。我是否需要提供其他的细节？
How can I achieve the functionality? I am getting stuck at this. I tried various combinations on Selectors. But nothing seems to be working for me. Do I need to provide any other detail?
推荐答案
我不知道它的的右键的解决方案，但我设置为的android：背景我的列表项：
I'm not sure it's the right solution, but I set this for the android:background on my list items:
<selector xmlns:android="http://schemas.android.com/apk/res/android"
android:exitFadeDuration="@android:integer/config_mediumAnimTime" >
<!-- I never see this one - the grid items are not focusable -->
<item android:state_pressed="false" android:state_focused="true" android:drawable="@drawable/list_focused" />
<!-- while pressed -->
<item android:state_pressed="true" android:drawable="@drawable/pressed_background" />
<!-- while selected in actionmode -->
<item android:state_activated="true" android:drawable="@color/pressed" />
<item android:drawable="@android:color/transparent" />
</selector>
我没有设置的android：在网格视图listSelector 属性
