Android Studio:创建一个进度条,将在 100% 时到达下一个 activity

Android Studio: Creating a progress bar that will lead to next activity at 100%

如何创建一个进度条,让应用程序在完成后从一个 activity 跳到下一个? (条形填充至 100%)

从 Android 开发者网站,我检索到以下示例代码,但我不确定 where/how 它是否使应用程序转到下一个屏幕:

public class 我的Activity 扩展 Activity { private static final int PROGRESS = 0x1;

 private ProgressBar mProgress;
 private int mProgressStatus = 0;

 private Handler mHandler = new Handler();

 protected void onCreate(Bundle icicle) {
     super.onCreate(icicle);

     setContentView(R.layout.progressbar_activity);

     mProgress = (ProgressBar) findViewById(R.id.progress_bar);

     // Start lengthy operation in a background thread
     new Thread(new Runnable() {
         public void run() {
             while (mProgressStatus < 100) {
                 mProgressStatus = doWork();

                 // Update the progress bar
                 mHandler.post(new Runnable() {
                     public void run() {
                         mProgress.setProgress(mProgressStatus);
                     }
                 });
             }
         }
     }).start();
 }

}

在您发布的代码中,您应该执行检查以查看 mProgressStatus 何时为 100%,然后从当前 Acrivity 开始 Intent 到您想要的 activity .
