我遇到了这个错误。
java.lang.ClassCastException:java.lang.Object[]无法转换为 java.lang.String []
以下是完整代码。
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edTenDangNhap =(EditText) findViewById(R.id.edTenDangNhap);
edMatKhau =(EditText) findViewById(R.id.edMatKhau);
btnDangKi =(Button) findViewById(R.id.btnDangKi);
btnDangNhap =(Button) findViewById(R.id.btnDangNhap);
btnDangNhap.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String tentk = edTenDangNhap.getText().toString();
String matkhau = edMatKhau.getText().toString();
// ==== I execute AsyncTask there
AsyncTask dangnhap = new AsyncDangNhap();
dangnhap.execute(tentk,matkhau); // IDE announce there : JDK 5.0 only. Unchecked to call execute Params ...
}
});
}
public class AsyncDangNhap extends AsyncTask<String[], Void, Integer>{//error there
@Override
protected Integer doInBackground(String[]... params) {
WebService sv = new WebService();
int kiemtra = sv.KiemTraDangNhap(params[0],params[1]);
return kiemtra;
}
@Override
