处理listview onItemClickListener

Question

我有一个带搜索框的listView，可以搜索列表视图。我在搜索每个项目以启动不同的活动时遇到了问题，因为当我搜索时，项目的位置和id会发生变化，因为列表视图只会显示搜索到的result.Can有人帮助?？

这是我的代码：

        public class MainActivity extends Activity implements OnItemClickListener {


EditText edittext;
ListView listview;




String[] text = { "One", "Two", "Three", "Four", "Five", "Six", "Seven",
"Eight", "Nine", "Ten" };

int[] image = { R.drawable.one, R.drawable.two, R.drawable.three,
R.drawable.four, R.drawable.five, R.drawable.six, R.drawable.seven,
R.drawable.eight, R.drawable.nine, R.drawable.ten };
int textlength = 0;
ArrayList text_sort = new ArrayList();
ArrayList image_sort = new ArrayList();

public void onCreate(Bundle savedInstanceState)
{

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

edittext = (EditText) findViewById(R.id.EditText01);
listview = (ListView) findViewById(R.id.ListView01);
listview.setAdapter(new MyCustomAdapter(text, image));
listview.setOnItemClickListener(this);






edittext.addTextChangedListener(new TextWatcher()
{

public void afterTextChanged(Editable s)
{

}

public void beforeTextChanged(CharSequence s, int start,
int count, int after)
{

}

public void onTextChanged(CharSequence s, int start,
int before, int count)
{

textlength = edittext.getText().length();
text_sort.clear();
image_sort.clear();

for(int i=0; i<text.length; i++)
{
if (textlength <= text[i].length())
{
if (edittext.getText().toString().
equalsIgnoreCase((String) text[i].subSequence(0, textlength)))
{
text_sort.add(text[i]);
image_sort.add(image[i]);
}
}
}

listview.setAdapter(new MyCustomAdapter
(text_sort, image_sort));

}
});
}


class MyCustomAdapter extends BaseAdapter
{

String[] data_text;
int[] data_image;

MyCustomAdapter()
{

}

MyCustomAdapter(String[] text, int[] image)
{
data_text = text;
data_image = image;
}
MyCustomAdapter(ArrayList text, ArrayList image)
{
data_text = new String[text.size()];
data_image = new int[image.size()];

for(int i=0; i<text.size(); i++)
{
data_text[i] = (String) text.get(i);
data_image[i] = (Integer) image.get(i);
}

}

public int getCount()
{
return data_text.length;
}

public String getItem(int position)
{
return null;
}

public long getItemId(int position)
{
return position;
}

public View getView(int position, View convertView, ViewGroup parent)
{

LayoutInflater inflater = getLayoutInflater();
View row;

row = inflater.inflate(R.layout.listview, parent, false);
TextView  textview = (TextView) row.findViewById(R.id.TextView01);
ImageView imageview = (ImageView) row.findViewById(R.id.ImageView01);

textview.setText(data_text[position]);
imageview.setImageResource(data_image[position]);

return (row);

}






}


@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id) {
    // TODO Auto-generated method stub

    //HOW SHOULD I HANDLE THE CLICKS HERE 






}
}

我的解决方案不起作用：

1)获取项目的位置并执行相应的活动

2)获取id .......................................................

Answer 1

@Override
public void onItemClick(AdapterView<?> arg0, View view, int position,long id) 
{
Intent i = new Intent(ActivityName.this,SecondActivity,class);
i.putExtra("key",position);
startActivity(i)
}
});

使用Intent在第二个活动中获取价值

int i = getIntent().getExtras().getInt("key");

Answer 2

在适配器的getView中，当您找到任何文本视图时，您可以setTag到类似your_text_view.setTag("TextView"+position);的位置。之后，您可以使用findViewWithTag()方法准确地查找单击了哪个textview或listItem。For ex: INSIDE GETVIEW ` `RelativeLayout = null；if (null == convertView) {

        String inflater = Context.LAYOUT_INFLATER_SERVICE;
        LayoutInflater vi;
        vi = (LayoutInflater) getContext().getSystemService(inflater);
        rel = (RelativeLayout) vi.inflate(resource, rel, true);

    } else {
        rel = (RelativeLayout) convertView;

    }
            rel.setTag("Txt:" + position);`

在那之后

` `final rel1 = rel；

    // click Listener of day list
    rel.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {


            String seletedPosition = (String) v.getTag();
            String[] splitted = seletedPosition.split(":");
            int tag = Integer.parseInt(splitted[1]);
            mPosition = tag;
            SELECTED_DATE = getItem(tag).date;  
                           if(SELECTED_DATE.equals("something")){
                            startActivity(new Intent(OldActivityContext,NewActivity.class));}`
