我从资产加载文本文件并在我的文本文件中使用 json 在列表视图中显示 一些学校我将我的 file_name.json 粘贴在下面的问题是我想过滤以仅显示特定学校的名称是"Middle Schools"
我如何过滤此行 JSONObject json2 = new JSONObject(jsonresult);
以仅显示该学校的名称是"MiddleSchool"
public String loadJSONFromAsset() {
String json = null;
try {
InputStream is = getAssets().open("file_name.json");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
jsonresult=json;
} catch (IOException ex) {
ex.printStackTrace();
return null;
}
return json;
}
JSONObject json2 = new JSONObject(jsonresult);
status = json2.getString("status");
if (status.equals("1")) {
message = "data";
JSONArray school = json2.getJSONArray("data");
for (int i = 0; i < school.length(); i++) {
JSONObject object = school.getJSONObject(i);
Category_ID.add(Long.parseLong(object
.getString("school_id")));
Category_name.add(object.getString("name"));
}
}
else {
message = "error";
}
}
文本文件:
