Question

接收短信，然后将EditText设置为msgBody

public class SmsBroadcastReceiver extends BroadcastReceiver {
//.....
     ((EditText)MainActivity.mThis.findViewById(R.id.editTextName)).setText(msgBody);}

此错误是在View中无法应用于android.view.View.Onclicklistiner

//onCreate
buttonSave.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            buttonSave.performClick(this);
        }
    });

单击buttonSave时，该消息将自动保存到SQLite并同步到Mysql

private void saveNameToServer() {
    final ProgressDialog progressDialog = new ProgressDialog(this);
    progressDialog.setMessage("Saving Name...");
    progressDialog.show();

    final String name = editTextName.getText().toString().trim();

    StringRequest stringRequest = new StringRequest(Request.Method.POST, URL_SAVE_NAME,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    progressDialog.dismiss();
                    try {
                        JSONObject obj = new JSONObject(response);
                        if (!obj.getBoolean("error")) {
                            //if there is a success
                            //storing the name to sqlite with status synced
                            saveNameToLocalStorage(name, NAME_SYNCED_WITH_SERVER);
                        } else {
                            //if there is some error
                            //saving the name to sqlite with status unsynced
                            saveNameToLocalStorage(name, NAME_NOT_SYNCED_WITH_SERVER);
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    progressDialog.dismiss();
                    //on error storing the name to sqlite with status unsynced
                    saveNameToLocalStorage(name, NAME_NOT_SYNCED_WITH_SERVER);
                }
            }) {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            Map<String, String> params = new HashMap<>();
            params.put("name", name);
            return params;
        }
    };

    VolleySingleton.getInstance(this).addToRequestQueue(stringRequest);
}

@Override
public void onClick(View view) {
    saveNameToServer();
}

当EditText值发生变化时，还有其他方法可以自动点击按钮吗？

只需调用buttonSave.performClick(this);方法即可保存数据，而无需调用点击saveNameToServer();。

buttonSave.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            //buttonSave.performClick(this); // remove, not required
            saveNameToServer(); // save your data
        }
    });

在editText中的每个字符串更改中自动单击saveButton
