To obtain the value of the selected item in ListView, you can follow these steps:<\/p>\n

    \n
  1. Obtain the ListView object: Retrieve the ListView object using the findViewById method.<\/li>\n
  2. Set OnItemClickListener: Set the click event of the ListView through the setOnItemClickListener method.<\/li>\n
  3. Retrieve the selected item’s value in the OnItemClickListener: obtain the selected item’s data object using the getItemAtPosition method, or get the position of the selected item using the getItemIdAtPosition method.<\/li>\n<\/ol>\n

    Here is a code example:<\/p>\n

    ListView<\/span> listView<\/span> =<\/span> findViewById(R.id.listView);\r\n\r\nlistView.setOnItemClickListener(new<\/span> AdapterView<\/span>.OnItemClickListener() {\r\n    @Override<\/span>\r\n    public<\/span> void<\/span> onItemClick<\/span>(AdapterView<?> parent, View view, int<\/span> position, long<\/span> id)<\/span> {\r\n        \/\/ \u83b7\u53d6\u9009\u4e2d\u9879\u7684\u503c<\/span>\r\n        Object<\/span> selectedItem<\/span> =<\/span> listView.getItemAtPosition(position);\r\n        \r\n        \/\/ \u6216\u8005\u83b7\u53d6\u9009\u4e2d\u9879\u7684\u4f4d\u7f6e<\/span>\r\n        long<\/span> selectedItemId<\/span> =<\/span> listView.getItemIdAtPosition(position);\r\n        \r\n        \/\/ \u8fdb\u4e00\u6b65\u5904\u7406\u9009\u4e2d\u9879\u7684\u503c<\/span>\r\n        \/\/ ...<\/span>\r\n    }\r\n});\r\n<\/code><\/pre>\n
    In this example, when a user clicks on an item in the ListView, it will trigger the onItemClick method of the OnItemClickListener. In this method, you can get the value of the selected item using the getItemAtPosition method, or get the position of the selected item using the getItemIdAtPosition method. Then, you can further process the value of the selected item as needed.<\/p>\n","protected":false},"excerpt":{"rendered":"
