Question

我使用listview创建了自定义SimpleAdapter，并且在列表视图的每一行中，我放了一个按钮具有单个ID。我希望每行的position都能通过按钮，但我每行都有一个按钮ID 我希望当我点击按钮时它找到的位置排并开始另一项活动 请帮帮我

public void click(View v){
    //RelativeLayout navi = (RelativeLayout)findViewById(R.layout.custom_row_view);
    TextView tv = (TextView)findViewById(R.id.text1);
    ImageButton im = (ImageButton)findViewById(R.id.imageButton1);
     ListView lv=(ListView)findViewById(android.R.id.list);
    int position = 0;
    Long id=Long.parseLong((String) adapter.getItem(position));

    Intent i=null;
    switch(position){
    case 1:
      i=new Intent(this, ButtonActivity.class);
        startActivity(i);
        break;
    case 2:
         i = new Intent(this, PickerActivity.class);
        startActivity(i);
        break;
    }

在列表视图中，您可以使用setOnItemClickListener

list.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {  
   public void onItemSelected(AdapterView parentView, View childView, int position, long id) {  
            //Put Your code here 
        }
        public void onNothingSelected(AdapterView parentView) {  

        }  
      });

我不确定这一点，但让我们尝试一下，并告诉我你的成功......

行int position = listView.getPositionForView(v.getParent());

public void click(View v){

    // This line is important
    int position =  listView.getPositionForView(v.getParent());

    //RelativeLayout navi = (RelativeLayout)findViewById(R.layout.custom_row_view);
    TextView tv = (TextView)findViewById(R.id.text1);
    ImageButton im = (ImageButton)findViewById(R.id.imageButton1);
     ListView lv=(ListView)findViewById(android.R.id.list);
    int position = 0;
    Long id=Long.parseLong((String) adapter.getItem(position));

    Intent i=null;
    switch(position){
    case 1:
      i=new Intent(this, ButtonActivity.class);
        startActivity(i);
        break;
    case 2:
         i = new Intent(this, PickerActivity.class);
        startActivity(i);
        break;
    }
  }

如果这不起作用，则只需选择自定义适配器，然后在适配器的onClick()中将按钮的getView()写入位置变量可访问。

试试这个

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

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

                final ProgressDialog progressBar = ProgressDialog.show(
                        VechiclesDetails.this, "", loadingString);

                progressBar.setIndeterminate(true);
                progressBar.setIndeterminateDrawable(getResources()
                        .getDrawable(R.anim.progressbar_handler));
                new Thread(new Runnable() {

                    public void run() {
                        try {
                            Intent carDetail = new Intent(
                                    Details.this,
                                    Screen.class);
                            carDetail.putExtra("index", arg2);
                            carDetail.putExtra("sellerId", SellerId);
                            startActivity(carDetail);
                            progressBar.dismiss();
                        } catch (Exception e) {
                            progressBar.dismiss();
                        }
                    }
                }).start();

            }
        });
