Java 当我搜索任何Listview项目，然后单击所需项目时，它总是打开列表视图的第一个位置

主课 问题是，当我要从listview中搜索任何所需的项目并单击该项目时，它总是打开我在程序中添加的第一个位置项目，而不是我搜索时所需的项目

在您的情况下，当您在搜索视图中输入文本时，它会从数组适配器中过滤出匹配项

因此，当您设置阵列适配器时，阵列的所有项都会重新定义它们的位置，而这些位置并不相同

在这里，您必须从sCheeseStrings

为此，您可以在下面的代码行中找到。如果你有任何疑问，请询问

      String itemValue = (String) mListView.getItemAtPosition(position);

      int itemPosition = 0;
            for (int i = 0; i < mStrings.length; i++) {
                if (itemValue.equalsIgnoreCase(mStrings[i])) {
                    itemPosition = i;
                }
            }

            if (itemPosition == 0) {
                String content = "android.intent.action.FIRST_PROG";
                Intent i = new Intent(content);
                startActivity(i);
            }
            if (itemPosition == 1) {
                Intent i = new Intent("android.intent.action.SECOND_PROG");
                startActivity(i);
            }
            if (itemPosition == 2) {
                Intent i = new Intent("android.intent.action.THIRD_PROG");
                startActivity(i);
            }

String itemValue=（String）mListView.getItemAtPosition（position）；
int itemPosition=0；
for（int i=0；i

为什么要将单击的列表项位置（int）保存在字符串变量中？！！！！

      String itemValue = (String) mListView.getItemAtPosition(position);

      int itemPosition = 0;
            for (int i = 0; i < mStrings.length; i++) {
                if (itemValue.equalsIgnoreCase(mStrings[i])) {
                    itemPosition = i;
                }
            }

            if (itemPosition == 0) {
                String content = "android.intent.action.FIRST_PROG";
                Intent i = new Intent(content);
                startActivity(i);
            }
            if (itemPosition == 1) {
                Intent i = new Intent("android.intent.action.SECOND_PROG");
                startActivity(i);
            }
            if (itemPosition == 2) {
                Intent i = new Intent("android.intent.action.THIRD_PROG");
                startActivity(i);
            }
