活动以某种方式起作用但不可见

【问题描述】：

我目前正在修改现有应用程序。以前一切都很完美，我不知道出了什么问题。基本上：

  1. 启动应用时会出现启动画面
  2. 2 秒后出现登录屏幕
  3. 登录后应该有一个主屏幕，但应用程序显然已关闭

发生了什么：

  1. Splash.java - 2 秒后启动 MainActivity

    public class Splash extends AppCompatActivity {

private final int SPLASH_DISPLAY_LENGTH = 2000;

@Override
public void onCreate(Bundle icicle) {
 super.onCreate(icicle);
 setContentView(R.layout.splash_screen);

 new Handler().postDelayed(new Runnable(){
     @Override
     public void run() {
         Intent mainIntent = new Intent(Splash.this,MainActivity.class);
         Splash.this.startActivity(mainIntent);
         Log.e("Splash", "startActivity");
         Splash.this.finish();
         Log.e("Splash", "finish");
     }
 }, SPLASH_DISPLAY_LENGTH);
}
}

  2. MainActivity.java - 显然它工作正常 - 我把日志消息放在这里，Logcat 告诉我方法正在运行并且 setContentView 也在工作。

    @Override
protected void onCreate(Bundle savedInstanceState) {

 Log.e(TAG, "main activity: " + "onCreate");

 startTimerService();

 //LanguageHelper.onAttach(this);
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 //setVisible(true);

 Log.e(TAG, "main activity: " + "setContentView");

 initUI();
 Log.e(TAG, "main activity: " + "initUI");

 androidx.appcompat.widget.Toolbar toolbar = findViewById(R.id.toolbar);
 toolbar.bringToFront();
 Log.e(TAG, "main activity: " + "toolbar");

 if(firstRun)
 {
     //YOUR FIRST RUN CODE HERE
     //int i  = RfidReaderSingleton.getInstance(this).RestoreFactory();

     //////////////////////////////////
     //checkCredentials();
     /////////////////////////////////

     checkForUpdates();
     checkBluetooth();
     //tcp_buttonToast.makeText(getApplicationContext(), "FIRST RUN: " + i, Toast.LENGTH_SHORT).show();
 }
 firstRun = false;

 Log.e(TAG, "main activity: " + "firstRun" + firstRun);

 showPhoneStatePermission();
 Log.e(TAG, "main activity: " + "showPhoneStatePermission");

}

CheckCredentials 负责打开日志屏幕，这部分也可以工作。

@Override
protected void onResume(){
    super.onResume();
    sendMessage(MSG_HIDE_WAIT, null);

    //ToDo
    checkCredentials();

    //GRID
    InitTest(this);
    Log.e("MainActivity", "InitTest");
    //GRID
}

private void checkCredentials(){
    UserModel userModel = DBUserAdapter.getInstance(this).userOperation.getUserModel();
    if(userModel.isRemembered()){
        if(!userModel.isLicenseActivated()){
            Toast.makeText(getApplicationContext(),
                    getText(R.string.logging_result_401) , Toast.LENGTH_LONG).show();
            Log.e("We'startLoginActivity", "1");
            startLoginActivity();
        }
        if(userModel.getToken().equals("")){
            Log.e("We'startLoginActivity", "2");
            startLoginActivity();

        }
    }
    else{
        if(!userModel.isUserStillLogin()){
            DBUserAdapter.getInstance(this).userOperation.cleanUserModel();
            Log.e("We'startLoginActivity", "3");
            startLoginActivity();
        }
    }
    DBUserAdapter.getInstance(this).userOperation.updateLastLogin();
    HttpUtils.SetToken(userModel.getToken());
}

 private void startLoginActivity(){
    mStartForResult.launch(new Intent(this, PlatformLoginActivity.class));
}
  1. 在 PlatformLoginActivity 中的正确日志完成后，这就是问题发生的时候。该应用程序只是关闭了，但 Logcat 中没有错误 - 没有消息。在 SplashScreen 成功后创建的 MainActivity（因为 MainActivity 负责打开 PlatformLoginActivity 并且这发生正确）。当 PlatformLoginActivity 完成时 MainActivity 不可见，应用关闭，但属于 MainActivity 的 toastmessage 在屏幕中可见。

我以前从未见过这样的行为，我不知道可能是什么问题 - 我试图记录应用程序中发生的事情，但显然它有效。

任何帮助将不胜感激，因为我不知道该怎么做。

【问题讨论】：

  • 你有日志猫的消息吗？
  • stackoverflow.com/questions/35364373/… 如果未显示日志错误，请查看此链接
  • @georkost 我已经添加了我在 logcat 中得到的消息
  • 你能完整发布你的MainActivity吗？
  • 我已经把它贴在@akhilnair下面了
