如何使活動認證出現在logo.please的動畫（啓動畫面）後面，請幫助我

Question

$第一次爲應用程序製作的，所以我的問題是讓佈局登錄出現在同一活動的splashscreen '動畫後 這是我的代碼splashscreen.java 問題出在哪裏？

public class Splashscreen extends Activity implements AdapterView.OnItemSelectedListener { 
    Spinner spinner; 
    Button btnCnx; 
    LinearLayout ln; 
    public void onAttachedToWindow() { 
     super.onAttachedToWindow(); 
     Window window = getWindow(); 
     window.setFormat(PixelFormat.RGBA_8888); 
    } 
    /** Called when the activity is first created. */ 
    Thread splashTread; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_splashscreen); 
     // btnCnx = (Button) findViewById(R.id.btn_Connexion); 
     // btnCnx.setCursorVisible(false); 
     //************************************************************** 
     ln = (LinearLayout) findViewById(R.id.LinLaySpalScrenLogin); 
     ln.setVisibility(View.INVISIBLE); 
     StartAnimations(); 
     Button Key_save = (Button) findViewById(R.id.btn_Connexion); 
     //Key_save.setVisibility(View.INVISIBLE); 
     Key_save.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Log.e("DEMO TAG", "CLick on sign in button"); 
       Intent intent = new Intent(Splashscreen.this, calendrier.class); 
       startActivity(intent); 
      } 
     }); 
//  ******************************************************** 
     // Spinner element 
     spinner = (Spinner) findViewById(R.id.fonction); 
     // Spinner click listener 
     spinner.setOnItemSelectedListener(this); 
     // Spinner Drop down elements 
     List<String> fonction = new ArrayList<String>(); 
     fonction.add("Administrateur"); 
     fonction.add("Agent laboratoire"); 
     fonction.add("Chef releve"); 
     fonction.add("Releveur"); 
     // Creating adapter for spinner 
     ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, fonction); 
     // Drop down layout style - list view with radio button 
     dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

//  Key_save.setVisibility(View.VISIBLE); 
    } 

    @Override 
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
     // On selecting a spinner item 
     String item = parent.getItemAtPosition(position).toString(); 
     // Showing selected spinner item 
     // Toast.makeText(parent.getContext(), "Vous avez choisit: " + item, Toast.LENGTH_LONG).show(); 
    } 
    public void onNothingSelected(AdapterView<?> arg0) { 
     // TODO Auto-generated method stub 
    } 
    private void StartAnimations() { 
     Animation anim = AnimationUtils.loadAnimation(this, R.anim.alpha); 
     anim.reset();

     ImageView iv = (ImageView) findViewById(R.id.splash); 
     iv.clearAnimation(); 
     iv.startAnimation(anim); 
     ln.setVisibility(View.VISIBLE);

       try { 
        int waited = 0; 
        // Splash screen pause time 
        while (waited < 3500) { 
         sleep(100); 
         waited += 100; 
        } 

        //Intent intent = new Intent(Splashscreen.this,

你將不得不創建或者一個活動，負荷Splash Screen即Intent i = new Intent(getApplicationContext, Authenticate.class);然後startActivity(i)之後。一旦加載，您可以使用getSharedPreferences獲取在設備上註冊的用戶列表，或者您可以從在線來源獲取用戶列表。從這一點，你可以設置一個boolean success這意味着用戶名和密碼匹配，在這種情況下，你可以使用上面相同的代碼來啓動Mainactivity。如果不是，您可以通過toast告知他們，更改textView等。
