如果我理解正确，您希望在一个JSON中显示上面格式化的TextView，但需要突出显示。查看this post。如果你想保持JSON的原始格式，我会得到最初的JSONArray，调用toString（），然后将文字替换为“name”和“sub-ingredient”。你想要的方式。

如果我误解了您想要提取每个JSONObject的值，您只需要遍历JSONArray

//format these to look like whatever you want
SpanableString nameTitle = "Name: "
SpanableString subIngredientTitle = " Sub-ingredient: ";
String concatProduct = "";
int arraySize = jsonArray.length();

for(int i = 0; i < arraySize; i++){
    JSONObject thing = jsonArray.getJSONObject(i);
    String name = thing.getString("name");
    String subIngredient = thing.getString("sub-ingredient");
    if(i == 0){
        concatProduct = nameTitle + name + subIngredientTitle + subIngredient;
     } else {
        concatProduct += " " + nameTitle + name + subIngredientTitle + subIngredient;
     }
}

textView.setText(concatProduct);

这样的事情可以让您处理JSONArray并构建一个可以设置为TextView的字符串。格式由您决定。
