我有两个网格视图。（我给的名字）
- 顶部网格视图：一些数字，如“123456123456”
- 底部网格视图：包含从 0 到 9 的数字
最初，gridview 中的所有项目都是空的（类似于不可见的）。基于单击底部网格视图中的项目，将显示顶部网格视图中的项目。
例如：假设顶部网格视图中的项目是“123456123456”。最初一切都是不可见的。单击底部网格视图中的项目后，我需要在顶部网格视图中显示适当的数字。可以说，我点击了 1。我拥有“1”的网格视图项目应该是可见的。
我尝试了这个逻辑，但是出了点问题，我得到了一些奇怪的结果。
看看输出：
如果您在单击 1 时看到输入“123456123456”的上图，则所有 1 都将变为可见。当我点击 2 时，2 变得可见，甚至额外的 1 被分配给网格。我不知道为什么会这样。
这是我尝试过的代码。
主要活动 ：
public class MainActivity extends Activity {
GridView grid_topNumbers;
GridView gridview_belownumbers;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gridview_belownumbers = (GridView)findViewById(R.id.gridview_belownumbers);
grid_topNumbers = (GridView)findViewById(R.id.gridview_topnumbers);
TopGrid topGridAdapter = new TopGrid(this);
Constants.topNumbers = "123456123456";
List<TopNumbersObject> topNumList = new ArrayList<TopNumbersObject>();
TopNumbersObject topnumObj = null;
for(int i=0;i< Constants.topNumbers.length();i++){
topnumObj = new TopNumbersObject();
if(i<Constants.topNumbers.length()-1)
{
topnumObj.number = (Constants.topNumbers.substring(i, i+1))+"";
}
else
{
topnumObj.number = (Constants.topNumbers.substring(i))+"";
}
topnumObj.isVisited =false;
topNumList.add(topnumObj);
}
Constants.TopNumbersList = topNumList;
grid_topNumbers.setAdapter(topGridAdapter);
gridview_belownumbers.setAdapter(new CustomGridViewAdapter(this,topGridAdapter));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
我的底部网格视图适配器：
public class CustomGridViewAdapter extends BaseAdapter {
Context cont;
LinearLayout.LayoutParams params = null;
TopGrid topAdapter = null;
public CustomGridViewAdapter(Context c,TopGrid topAdapter) {
params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
cont = c;
this.topAdapter = topAdapter;
// type = Typeface.createFromAsset(cont.getAssets(),
// "fonts/letters_fonttype.ttf");
}
@Override
public int getCount() {
return 10;
}
@Override
public Object getItem(int arg0) {
return arg0;
}
@Override
public long getItemId(int arg0) {
return arg0;
}
@Override
public View getView(int arg0, View convertView, ViewGroup arg2) {
View v;
TextView tv;
// if it’s not recycled, initialize some
// attributes
LayoutInflater li = (LayoutInflater) cont
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = li.inflate(R.layout.bottom_grid, null);
tv = (TextView) v.findViewById(R.id.bottom_grid_item_textView1);
tv.setText(arg0+"");
tv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
TextView clickedTextView = (TextView)arg0;
String letter = clickedTextView.getText().toString();
for(int i=0;i<Constants.topNumbers.length();i++)
{
TopNumbersObject letterObject = Constants.TopNumbersList.get(i);
if(letterObject.number.equalsIgnoreCase(letter))
{
letterObject.isVisited = true;
if(Constants.topNumbers.toLowerCase().lastIndexOf(letter.toLowerCase()) == i)
{
topAdapter.notifyDataSetChanged();
break;
}
}
}
clickedTextView.setClickable(false);
clickedTextView.setOnClickListener(null);
}
});
return v;
}
}
我的顶级网格适配器：
public class TopGrid extends BaseAdapter {
Context cont;
LinearLayout.LayoutParams params = null;
public TopGrid(Context c) {
params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
cont = c;
}
@Override
public int getCount() {
return Constants.TopNumbersList.size();
}
@Override
public Object getItem(int arg0) {
return arg0;
}
@Override
public long getItemId(int arg0) {
return arg0;
}
@Override
public View getView(int arg0, View convertView, ViewGroup arg2) {
View v =convertView;
TextView tv;
TopNumbersObject topnoObject = (Constants.TopNumbersList.get(arg0));
Holder h;
if (v == null) // if it’s not recycled, initialize some attributes
{
h=new Holder();
LayoutInflater li = (LayoutInflater) cont
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = li.inflate(R.layout.top_numbers_item, null);
h.tv = (TextView) v.findViewById(R.id.top_grid_item_textView1);
v.setTag(h);
}
else
{
h=(Holder)v.getTag();
}
if(topnoObject.isVisited)
{
h.tv.setText(topnoObject.number);
}
Log.e("letters", topnoObject.number+ " "+topnoObject.isVisited+" "+arg0);
return v;
}
private static class Holder
{
TextView tv;
}
}
常量文件：
public class Constants {
public static boolean ISGRE;
public static String topNumbers = "1234567890";
public static List<TopNumbersObject> TopNumbersList = null;
public static int chances = 8;
}
下一个我的 xml 文件：

谁能建议我哪里出错了。
