Question

我正在创建一个Android应用程序的活动，用户填写他的详细信息（由id的名称，bhawan，房间，手机，书籍等标识），这些值将直接传输到Google电子表格。它给了我这个奇怪的错误。你能帮我吗？提前谢谢。

public class MainActivity extends Activity {

    final EditText nameField = (EditText) findViewById(R.id.EditTextName);  
    String name = nameField.getText().toString(); 

    final EditText bhawanField = (EditText) findViewById(R.id.EditTextBhawan);  
    String bhawan = bhawanField.getText().toString();

    final EditText roomField = (EditText) findViewById(R.id.EditTextRoom);  
    String room = roomField.getText().toString();

    final EditText mobileField = (EditText) findViewById(R.id.EditTextPhone);  
    String mobile = mobileField.getText().toString();

    final EditText emailField = (EditText) findViewById(R.id.EditTextEmail);  
    String email = emailField.getText().toString();

    final EditText bookField = (EditText) findViewById(R.id.EditTextBook);  
    String book = bookField.getText().toString();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);         

        Button sendButton = (Button) findViewById(R.id.ButtonSubmit);
        sendButton.setOnClickListener(new OnClickListener() {           
            public void onClick(View v) {
                btn_Click();
            }}
        );
    }

Answer 1

尝试更改：

HttpPost.setEntity(new UrlEncodedFormEntity(results));

到

post.setEntity(new UrlEncodedFormEntity(results));

当你不是一个静态方法时，你以前用来调用静态函数的方式调用setEntity（）。您可能想要使用之前创建的post对象来调用它。

Answer 2

HttpPost是一个静态类，但setEntity（）是一个非静态方法。要调用非静态方法，您需要使用new关键字或类提供的其他方法实例化类的实例，例如myHttpPost。

获取错误“无法从类型HttpEntityEnclosingRequestBase中对非静态方法setEntity（HttpEntity）进行静态引用”
