如何从url中正确读取JSON数组数据

Question

我正试图使用VOLLEY将json数据从url解析到我的应用程序这是我的JSON:

}
}

我想显示"ayahs"数组，但只显示"text"对象将它们放在string中，并使用intent将它们发送到另一个activity，并在textView中显示它们请帮帮我

这是我的分析方法

public String[] parseJSON(){
final String[] myText=new String[6];
String url = "http://api.alquran.cloud/v1/surah/1";
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
JSONObject jsonObject=response.getJSONObject("data");
JSONArray jsonArray=jsonObject.getJSONArray("ayahs");
for(int i=0;i==jsonArray.length();i++){
JSONObject aya=jsonArray.getJSONObject(i);
String text=aya.getString("text");
myText[i] =text;
}

} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
});
mRequestQueue.add(request);

return myText;
}

这是我的意向发送方法

public void onItemClick(int position) {
//ExampleItem clickedItem = mExampleList.get(position);
// final int sorahNumber=++position;

Intent detailIntent = new Intent(this, DetailActivity.class);
String[] myText = parseJSON();
detailIntent.putExtra("text", myText);
startActivity(detailIntent);

}

这是我的意图捕捉

public class DetailActivity extends AppCompatActivity {
private TextView sorah_tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);

sorah_tv=findViewById(R.id.sorah_tv);
Intent intent=getIntent();
String[] text=intent.getStringArrayExtra("text") ;
for(int i=0;i<text.length;i++){
sorah_tv.setText(text[i]);
}

请帮帮我

Answer 1

我的猜测是循环是错误的，而不是这个：

for(int i=0;i==jsonArray.length();i++){
JSONObject aya=jsonArray.getJSONObject(i);
String text=aya.getString("text");
myText[i] =text;
}

这样做：

for(int i=0;i<jsonArray.length();i++){
JSONObject aya=jsonArray.getJSONObject(i);
String text=aya.getString("text");
myText[i] =text;
}

更新：

我认为您会得到错误OutOfBoundException，因为JSON数组中有7个对象，而myText数组的大小为6:

因此：

final String[] myText=new String[6];

这样做：

final String[] myText=new String[7];
