java - 将数据从 MySQL 传递到另一个 Activity 中的选取框 TextView

Question

我将数据从 MySQL 传递到第一个 Activity 中的选取框文本并且它成功运行，但我需要将这些文本发送到另一个 Activity 而不是为我警告，请帮助

Activity 一:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dollars);
    item_k001 = findViewById(R.id.item_k101);
    item_k002 = findViewById(R.id.item_k102);
    requestQueue = Volley.newRequestQueue(this);
    JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, url, null,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    final Globalv globalv = (Globalv) getApplicationContext();
                    try {
                        JSONArray jsonArray = response.getJSONArray("allegg");
                        String msg = "";
                        for (int i = 0; i < response.length(); i++) {
                            JSONObject respons = jsonArray.getJSONObject(i);
                            final String myItem_k001 = respons.getString("item_k1");
                            final String myItem_k002 = respons.getString("item_k2");
                            DollarsActivity.this.runOnUiThread(new Runnable() {
                                public void run() {
                                    item_k001.setText(myItem_k001);
                                    item_k002.setText(myItem_k002);
                                }
                            });
                        }
                        JSONObject respons2 = jsonArray.getJSONObject(0);
                        String id = respons2.getString("id");
                        globalv.setTotal_threads(Integer.parseInt(String.valueOf(id)));
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }

            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e("VOLLEY", "ERROR");
        }
    }
    );

我想将拖车文本发送到 Activity 拖车:

        //defines variables to the xml elements.
        TextView tv1 = (TextView) findViewById(R.id.marqueeTextView1);
        TextView tv2 = (TextView) findViewById(R.id.marqueeTextView2);
        ///  You can change your text here
        tv1.setText("Text view");
        tv2.setText("Text view   ");
        // We set the setSelected value to true for the shift of the texts
        tv1.setSelected(true);
        tv2.setSelected(true);

Answer 1

请尝试以下代码:

Activity 1

intent = new Intent(OneActivity.this, TwoActivity.class);
intent.putExtra("KEY1", myItem_k001);
intent.putExtra("KEY2", myItem_k002);
startActivity(intent);

Activity 2

//In onCreate()
Intent intent = getIntent();
text1 = intent.getStringExtra("KEY1");
text2 = intent.getStringExtra("KEY2")
tv1.setText(text1);
tv2.setText(text2);
