我有GridView BaseAdapter，显示6个这样的按钮：
B11 B12
B21 B22
B31 B32
B11 B12 B21
B22 B31 B32
一切都很好，直到我从风景转回肖像。然后显示：
B11 B12
B21 B22
B11 B32
所以它显示 B11 两次。当我点击它时，它仍然会得到正确的位置（4）并崩溃，因为它无法找到正确的按钮ID。
以下是适配器的代码：
public class RightSlideMenuGridAdapter extends BaseAdapter {
private Context mContext;
private String TAG = "RightSlideMenuGridAdapter";
public RightSlideMenuGridAdapter(Context c) {
mContext = c;
}
public int getCount() {
return 6;
}
public Object getItem(int position) {
Log.i(TAG, "getItem" + Integer.toString(position));
return null;
}
public long getItemId(int position) {
Log.i(TAG, "getItemId" + Integer.toString(position));
long retId = 0;
// Nothing worked here. Maybe I should return something?
return retId;
}
// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
View child = convertView;
if (child == null) {
Context c = CobraApplication.getAppContext();
Log.i(TAG, "getView" + Integer.toString(position));
switch (position) {
case 0:
child = (View) ((LayoutInflater) CobraApplication
.getAppContext().getSystemService(
Context.LAYOUT_INFLATER_SERVICE)).inflate(
R.layout.toolscity, null);
Button btnToolscityhwy = (Button) child

btnToolscityhwy.setBackgroundDrawable(CobraApplication
.getAppContext().getResources()
.getDrawable(R.drawable.toolshwy));
btnToolscityhwy.setText(c.getResources().getString(
R.string.city));
} else {
btnToolscityhwy.setBackgroundDrawable(CobraApplication

R.layout.toolscarfinderbutton, null);
ToggleButton btnToolsCarFinder = (ToggleButton) child
.findViewById(R.id.myToggleButtoncarfinder);
// VK: Here we need to check the current setting of car finder
// and set button state appropriately
if (PersistentStoreHelper
.getNonDetectorSetting(NonDetectorSettings.CAR_FINDER_SETTING
.name()) == CommunicationProtocol.DIR_MOB_IRAD_SETTING_ON) {
btnToolsCarFinder.setChecked(true);
} else {
btnToolsCarFinder.setChecked(false);
}
break;

ToggleButton btnToolsTraffic = (ToggleButton) child

btnToolsTraffic.setChecked(PersistentStoreHelper
.getTrafficDisplayState());
break;
case 3:
child = (View) ((LayoutInflater) CobraApplication
.getAppContext().getSystemService(
Context.LAYOUT_INFLATER_SERVICE)).inflate(
R.layout.toolsmenulegend, null);
break;
case 4:
child = (View) ((LayoutInflater) CobraApplication
.getAppContext().getSystemService(
Context.LAYOUT_INFLATER_SERVICE)).inflate(
R.layout.toolsmusic, null);
ToggleButton btnToolsMusic = (ToggleButton) child
.findViewById(R.id.myToggleButtonMusicControl);
btnToolsMusic.setChecked(PersistentStoreHelper
.getMusicControlDisplayState());
break;
case 5:
child = (View) ((LayoutInflater) CobraApplication
.getAppContext().getSystemService(
Context.LAYOUT_INFLATER_SERVICE)).inflate(
R.layout.toolsdirectionsmenu, null);
break;
}
}
child.setPadding(0, 0, 0, 0);
child.setFocusable(false);
child.setClickable(false);
return child;
}
以下是GridInit肖像的痕迹 - 好的。然后将方向改为横向 - 仍然可以。然后回到肖像。它会两次获得View。
