所以我试图将不同的按钮输出加载到子类中,所以我需要setContentView和onCreate方法(我认为),以便可以触发findViewById函数来触发使用按钮的不同方法。
我在这里输入了错误的代码
esp_err_t index_post_handler(httpd_req_t *req)
{
uint8_t buffer[100];
wifi_config_t wifi_config;
httpd_req_recv(req, (char *) buffer, 100);
if (httpd_query_key_value((char *) buffer, "ssid", (char *) wifi_config.sta.ssid, 32) == ESP_ERR_NOT_FOUND) {
httpd_resp_set_status(req, "400");
httpd_resp_send(req, "SSID required", -1);
return ESP_OK;
}
if (httpd_query_key_value((char *) buffer, "password", (char *) wifi_config.sta.password, 64) == ESP_ERR_NOT_FOUND) {
httpd_resp_set_status(req, "400");
httpd_resp_send(req, "Password is required", -1);
return ESP_OK;
}
if (strlen((char *) wifi_config.sta.ssid) < 1) {
httpd_resp_set_status(req, "400");
httpd_resp_send(req, "Invalid ssid", -1);
return ESP_OK;
}
ESP_LOGI(TAG, "SSID: %s, Pass: %s", wifi_config.sta.ssid, wifi_config.sta.password);
httpd_resp_send(req, "<h1>OK</h1>", -1);
ESP_ERROR_CHECK(esp_wifi_stop());
ESP_ERROR_CHECK(esp_wifi_restore());
ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_STA) );
ESP_ERROR_CHECK(esp_wifi_set_config(ESP_IF_WIFI_STA, &wifi_config) );
ESP_ERROR_CHECK(esp_wifi_start());
return ESP_OK;
}

它显示了onCreate和setContentView上的问题,并且似乎对整个项目产生了错误。有没有人遇到过导致这个人显示不正确的问题?这仅适用于标记为LoadGuitar的子类。在我的主要班级...
public class LoadGuitar {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_berries);
工作正常!
请帮助任何人解决这个问题。谢谢。
答案 0 :(得分:0)
oncreate()和setcontentview()是在Activity类中定义的;要覆盖或调用它们,必须使用LoadGuitar扩展Activity类;
public class LoadGuitar extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_berries);
...
}
