我之前問過這個問題，但那時我沒有PHP文件，現在我已經創建了PHP文件，並將其保存在我的xampp文件夾，其工作我已檢查過它，問題出在代碼的某處。我想鏈接我的android studio註冊頁面與數據庫，但它不工作。當用戶輸入他們的詳細信息時，它應該自動將它保存在我在phpmyadmin上創建的數據庫中，但是當我點擊應用程序中的註冊時，什麼都不會發生。我要通過下面的代碼，請有人告訴我這個問題？ 感謝如何連接phpmyadmin數據庫與Android應用程序
這是我註冊Java類
ublic class Register extends Activity {
EditText ET_FIRST_NAME, ET_LAST_NAME, ET_ADDRESS, ET_EMAIL, ET_PASSWORD;
String first_name,last_name,address,email,password;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
ET_FIRST_NAME = (EditText)findViewById(R.id.etFname);
ET_LAST_NAME = (EditText)findViewById(R.id.etLname);
ET_ADDRESS = (EditText)findViewById(R.id.etAddress);
ET_EMAIL = (EditText)findViewById(R.id.etEmail);
ET_PASSWORD = (EditText)findViewById(R.id.etPassword);
}
public void btRegister(View view)
{
first_name = ET_FIRST_NAME.getText().toString();
last_name = ET_LAST_NAME.getText().toString();
address = ET_ADDRESS.getText().toString();
email = ET_EMAIL.getText().toString();
password = ET_PASSWORD.getText().toString();
String method = "register";
BackgroundTask backgroundTask = new BackgroundTask(this);
backgroundTask.execute(method, first_name,last_name,address,email,password);
finish();
}
}
