在安卓中添加启动屏幕时出现java错误

Question

我是安卓开发新手，我正在尝试在我的应用程序中添加一个启动屏幕。 我找到了这个tutorial:

我已经添加了教程中提到的文件，但似乎不起作用，我的Splashscreen.java文件中有一个错误

它给我的错误是无法解析符号安卓mkab

谢谢你提前帮忙

import com.安卓mkab.randomsplash.MainActivity;

import java.util.Random;


public class Splashscreen extends Activity {

    Thread splashTread;
    ImageView imageView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splashscreen);
        imageView = (ImageView)findViewById(R.id.imageView2);
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        int[] ids = new int[]{R.drawable.s_img,R.drawable.s_image_black, R.drawable.s_image_black2};
        Random randomGenerator = new Random();
        int r= randomGenerator.nextInt(ids.length);
        this.imageView.setImageDrawable(getResources().getDrawable(ids[r]));

        splashTread = new Thread() {
            @Override
            public void run() {
                try {
                    int waited = 0;
                    // Splash screen pause time
                    while (waited < 3500) {
                        sleep(100);
                        waited += 100;
                    }
                    Intent intent = new Intent(Splashscreen.this,
                            MainActivity.class);
                    intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                    startActivity(intent);

Answer 1

问题似乎是您正在尝试调用项目中不存在的包androidmkab.randomsplash.MainActivity应替换为您的项目包。例如com.myApplication.MainActivity

Answer 2

删除行com.androidmkab.randomsplash.MainActivity;并写入com.myapplication.MainActivity;

Answer 3

import com.androidmkab.randomsplash.MainActivity;从top中删除此行。这不是你的包裹。。。改为import com.myapplication.MainActivity
