android/ java -等待一个消耗时间的方法(例如: apicall )返回，然后执行其他代码

public interface ApiResponseCallback {
    void onSuccess(Response response);
    void onFailure(Error error);
}

public class ApiClient {
    public void apicall(final ApiResponseCallback callback) {
        // 模拟异步操作
        new Thread(new Runnable() {
            @Override
            public void run() {
                // 模拟耗时操作
                try {
                    Thread.sleep(2000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

                // 模拟返回结果
                Response response = new Response();
                response.setData("API response data");

                // 判断成功或失败，并回调相应的方法
                if (response.isSuccess()) {
                    callback.onSuccess(response);
                } else {
                    callback.onFailure(new Error("API request failed"));
                }
            }
        }).start();
    }
}

public class MainActivity extends AppCompatActivity {
    private ApiClient apiClient;

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

        apiClient = new ApiClient();

        // 调用apicall方法，并传入回调接口的实现
        apiClient.apicall(new ApiResponseCallback() {
            @Override
            public void onSuccess(Response response) {
                // 处理成功返回的结果
                String data = response.getData();
                Log.d("MainActivity", "API response: " + data);

                // 执行其他代码
                performOtherTasks();
            }

            @Override
            public void onFailure(Error error) {
                // 处理失败情况
                Log.e("MainActivity", "API request failed: " + error.getMessage());
            }
        });
    }

    private void performOtherTasks() {
        // 在这里执行其他代码
        Log.d("MainActivity", "Performing other tasks...");
    }
}
