安卓:如何在string.xml中创建多维数组

String[][] multiArray = new String[][] {
    { "1", "2", "3" },
    { "4", "5", "6" },
    { "7", "8", "9" }
};

<string name="array_row1">1,2,3</string>
<string name="array_row2">4,5,6</string>
<string name="array_row3">7,8,9</string>

String[] row1 = getResources().getString(R.string.array_row1).split(",");
String[] row2 = getResources().getString(R.string.array_row2).split(",");
String[] row3 = getResources().getString(R.string.array_row3).split(",");
String[][] multiArray = new String[][] { row1, row2, row3 };

{
  "array": [
    ["1", "2", "3"],
    ["4", "5", "6"],
    ["7", "8", "9"]
  ]
}

InputStream inputStream = getAssets().open("array.json");
int size = inputStream.available();
byte[] buffer = new byte[size];
inputStream.read(buffer);
inputStream.close();
String jsonString = new String(buffer, "UTF-8");

JSONObject jsonObject = new JSONObject(jsonString);
JSONArray jsonArray = jsonObject.getJSONArray("array");
String[][] multiArray = new String[jsonArray.length()][];
for (int i = 0; i < jsonArray.length(); i++) {
    JSONArray innerArray = jsonArray.getJSONArray(i);
    String[] innerArrayValues = new String[innerArray.length()];
    for (int j = 0; j < innerArray.length(); j++) {
        innerArrayValues[j] = innerArray.getString(j);
    }
    multiArray[i] = innerArrayValues;
}
