android gridview 每个item设置不同的图片selector，要求达到点击item互斥，并保留点中的item背景状态

[qq_20397397]

如题
y一、activity中增加gridview.setOnItemClickListener监听，遍历子

public class MainActivity extends Activity {
private MyGridView gridview;

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();

initEvent();
}

private void initEvent() {
// TODO Auto-generated method stub
gridview.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {

// TODO Auto-generated method stub
int total = arg0.getChildCount();
for (int i = 0; i < total; i++) {
View view = arg0.getChildAt(i);
ToggleButton button = (ToggleButton) view.findViewById(R.id.iv_item);
if(i != arg2){
button.setChecked(false);
}else {
button.setChecked(true);
}
}
}
});
}

private void initView() {
gridview = (MyGridView) findViewById(R.id.gridview);
gridview.setAdapter(new MyGridAdapter(this));
}
}

二、item.xml使用toggle保留按下状态
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_margin="0.0dip"
android:background="@android:color/white" >

<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerInParent="true"
android:background="@drawable/bg_gv"
android:padding="12.0dip" >

<ToggleButton
android:id="@+id/iv_item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:focusable="false"
android:clickable="false"
android:textOn=""
android:textOff="" />

<TextView
android:id="@+id/tv_item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/iv_item"
android:layout_centerHorizontal="true"
android:layout_marginTop="5.0dip"
android:maxLines="1"
android:textColor="@color/commo_text_color"
android:textSize="14.0sp" />
</RelativeLayout>

</RelativeLayout>

三、adapter中设置每个item的selector。xml文件
public class MyGridAdapter extends BaseAdapter {
private Context mContext;

public String[] img_text = { "转账", "余额宝", "手机充值", "信用卡还款", "淘宝电影", "彩票", "当面付", "亲密付", "机票", };
public int[] imgs = { R.drawable.bsx, R.drawable.circlex,
R.drawable.cubex, R.drawable.colorx,
R.drawable.cubex, R.drawable.cxx,
R.drawable.dbxx, R.drawable.eraserx, R.drawable.gyx };

public MyGridAdapter(Context mContext) {
super();
this.mContext = mContext;
}

@Override
public int getCount() {
// TODO Auto-generated method stub
return img_text.length;
}

@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}

@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(mContext).inflate(
R.layout.grid_item, parent, false);
}
TextView tv = BaseViewHolder.get(convertView, R.id.tv_item);
final ToggleButton iv = BaseViewHolder.get(convertView, R.id.iv_item);
iv.setBackgroundResource(imgs[position]);
tv.setText(img_text[position]);
// iv.setOnClickListener(new OnClickListener() {
//
// @Override
// public void onClick(View v) {
// // TODO Auto-generated method stub
// iv.setBackgroundResource(imgs[position]);
// }
// });
return convertView;
}

// public List<View> getConvertViews() {
// return convertViews;
// }
}

但是现在的问题是，item1、2、3、5可以互斥，点击其他item以后就都没有保留选中样式，求大神指导啊

在adapter方法中定义一个选中位置的方法 在onItemClickLIstener中调用，就可以了 adapter.setSelectedPosition(position); adapter.notifyDataSetInvalidated();

楼上的方法可行
