Question

晚安，

我是编程新手，并试图让项目在android studio中运行，但它一直失败，设计模式不起作用，因为它没有成功构建。任何提示将非常感谢。这是我在mainactivity.java文件中的内容。

我已经有其他程序可以在android studio中正常运行，但似乎无法使这个程序正常工作。

package com.example.jenna.needtograduate;

import android.animation.Animator;
import android.animation.AnimatorListenerAdapter;
import android.os.Handler;
import android.os.Looper;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import android.view.View;
import android.widget.ProgressBar;
import android.widget.RelativeLayout;

import java.util.Timer;

public class MainActivity extends AppCompatActivity implements MainTimerDelegate {

    private MainTimer timer;
    private RelativeLayout myLayout;
    private RelativeLayout authorizationContainerLayout;
    private RelativeLayout authorizationLayout;
    private RelativeLayout connectivityContainerLayout;
    private RelativeLayout connectivityLayout;
    private ProgressBar connectivityProgressBar;

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

        myLayout = (RelativeLayout) findViewById(R.id.myLayout);
        authorizationContainerLayout = (RelativeLayout) findViewById(R.id.authorizationContainerLayout);
        authorizationLayout = (RelativeLayout) findViewById(R.id.authorizationLayout);
        connectivityContainerLayout = (RelativeLayout) findViewById(R.id.connectivityContainerLayout);
        connectivityLayout = (RelativeLayout) findViewById(R.id.connectivityLayout);
        connectivityProgressBar = (ProgressBar) findViewById(R.id.connectivityProgressBar);

        timer = new MainTimer(this);
    }

    //region: Obstacle delegate methods
    public void MainTimerDidDetectReachability(MainTimer timer, Boolean reachable) {

        if (reachable) {

                    // perform if connection is available
                    connectivityLayout.animate()
                            .setDuration(250)
                            .alpha(0.0f)

                            .alpha(1.0f)
                            .setListener(new AnimatorListenerAdapter() {

                                @Override

                                    super.onAnimationEnd(animation);

                                                @Override

                                                    super.onAnimationEnd(animation);

                                                    // optional completion block
                                                }
                                            });
                                }
                            });
                }
            });
        }
    }
}

这是我收到的错误消息：

您的项目似乎存在fadedBlack。尝试检查colors.xml文件夹下的values。

构建保持失败
