Question

所以我的应用程序有点问题。我将相同的布局11次添加到我的主布局，在这里我向他们添加文字。问题是，没有文字显示。对不起我不完美的英语。：d

JSONParser parser = new JSONParser();
HashMap<String, String> params = new HashMap<>();
params.put("username", username);
params.put("pass", password);
JSONObject json = parser.makeHttpRequest(link to php file, params);

ArrayList<String> stundenList = new ArrayList<>();

int success = json.getInt("success");

if (success == 1) {
    JSONArray stunden = json.getJSONArray("stundenplan");

    for (int i = 0; i < stunden.length(); i++) {
        JSONObject c = stunden.getJSONObject(i);

        String montag = c.getString("montag");
        String dienstag = c.getString("dienstag");
        String mittwoch = c.getString("mittwoch");
        String donnerstag = c.getString("donnerstag");
        String freitag = c.getString("freitag");

        stundenList.add(montag);
        stundenList.add(dienstag);
        stundenList.add(mittwoch);
        stundenList.add(donnerstag);
        stundenList.add(freitag);
    }
    for(int i = 0; i < getRows().size(); i++) {
        LinearLayout ll = (LinearLayout) Karo.main.findViewById(getRows().get(i));
        TextView column1 = (TextView) ll.findViewById(R.id.column1);
        TextView column2 = (TextView) ll.findViewById(R.id.column1);
        TextView column3 = (TextView) ll.findViewById(R.id.column1);
        TextView column4 = (TextView) ll.findViewById(R.id.column1);
        TextView column5 = (TextView) ll.findViewById(R.id.column1);
        TextView column6 = (TextView) ll.findViewById(R.id.column1);
        TextView column7 = (TextView) ll.findViewById(R.id.column1);
        TextView column8 = (TextView) ll.findViewById(R.id.column1);
        TextView column9 = (TextView) ll.findViewById(R.id.column1);
        TextView column10 = (TextView) ll.findViewById(R.id.column1);
        TextView column11 = (TextView) ll.findViewById(R.id.column1);

        column1.setText(stundenList.get(i).split(";")[0]);
        column2.setText(stundenList.get(i).split(";")[1]);
        column3.setText(stundenList.get(i).split(";")[2]);
        column4.setText(stundenList.get(i).split(";")[3]);
        column5.setText(stundenList.get(i).split(";")[4]);
        column6.setText(stundenList.get(i).split(";")[5]);
        column7.setText(stundenList.get(i).split(";")[6]);
        column8.setText(stundenList.get(i).split(";")[7]);
        column9.setText(stundenList.get(i).split(";")[8]);
        column10.setText(stundenList.get(i).split(";")[9]);
        column11.setText(stundenList.get(i).split(";")[10]);
    }
}

getRows函数：

private static List<Integer> getRows() {
    List<Integer> rows = new ArrayList<>();
    rows.add(R.id.stundenplan_montag);
    rows.add(R.id.stundenplan_dienstag);
    rows.add(R.id.stundenplan_mittwoch);
    rows.add(R.id.stundenplan_donnerstag);
    rows.add(R.id.stundenplan_freitag);
    return rows;
}

Answer 1

问题在于您要通过id = R.id.column1查找11次视图，但是您应该找到包含ID R.id.column1，R.id.column2，R.id.column3等的视图：

...
for(int i = 0; i < getRows().size(); i++) {
    LinearLayout ll = (LinearLayout) Karo.main.findViewById(getRows().get(i));
    TextView column1 = (TextView) ll.findViewById(R.id.column1);
    TextView column2 = (TextView) ll.findViewById(R.id.column2);
    TextView column3 = (TextView) ll.findViewById(R.id.column3);
    ...
    ...

    column1.setText(stundenList.get(i).split(";")[0]);
    column2.setText(stundenList.get(i).split(";")[1]);
    column3.setText(stundenList.get(i).split(";")[2]);
    ...
    ...
}

在一个布局中相同的布局多个时间不能正常工作
