我正在创建一个 android 应用程序的活动，用户在其中填写他的详细信息（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。它给了我那个奇怪的错误。你能帮我吗 ？提前致谢。

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();
            }}
        );
    }   

    public void btn_Click(){
         SendHttpRequset();       
    }

尝试改变：

HttpPost.setEntity(new UrlEncodedFormEntity(results));

至

post.setEntity(new UrlEncodedFormEntity(results));

您之前以调用静态函数的方式调用 setEntity()，但它不是静态方法。您可能打算使用post您之前创建的对象来调用它。

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关键字或该类提供的其他方法实例化该类的一个实例，例如myHttpPost。
