我mainactivity.java

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

      LayoutInflater inflater = getLayoutInflater(); 

      View row = inflater.inflate(R.layout.row, parent, false); 

      TextView textview = (TextView) row.findViewById(R.id.tvTop); 
      ImageView imageview = (ImageView) row 
        .findViewById(R.id.list_image); 

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

      row.setOnClickListener(new OnClickListener() { 

       public void onClick(View convertView) { 

        String product = ((TextView) convertView).getText().toString(); 

        Intent i = new Intent(getApplicationContext(), 
          SecondScreenActivity.class); 
        i.putExtra("name", product); 

        startActivity(i); 


       } 
      }); 

      return (row);

例如，您可以顯示您的onCreate方法和活動XML？ –

接受有史以來的答案 –

你要這個

public void onClick(View row) { 
      TextView textview = (TextView) row.findViewById(R.id.tvTop); 

      String product = textView.getText().toString(); 

      Intent i = new Intent(getApplicationContext(), 
        SecondScreenActivity.class); 
      i.putExtra("name", product); 

      startActivity(i); 


     }

您正在嘗試佈局轉換爲一個TextView。 LinearLayout正在接收點擊。

String product = ((TextView) convertView).getText().toString();

這裏，convertView不是TextView。這是一個LinearLayout。

你可能想要這個：

String product = ((TextView) convertView.findViewbyId(R.id.tvTop)).getText().toString();
