我有一個對話框和一個線程。線程完成後,我想執行對話框。問題有時會執行,有時不會。我不明白爲什麼會發生這種情況。線程不執行對話框?

我該如何解決?

/** display dialog */ 
private void showDialog(int status){ 
    final Dialog dialog = new Dialog(getView().getContext()); 
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); 
    dialog.getWindow().setFlags(LayoutParams.FLAG_FULLSCREEN, LayoutParams.FLAG_FULLSCREEN);       
    dialog.setContentView(R.layout.custom_dialog); 
    dialog.getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT); 
    dialog.setCancelable(false); 
    ImageView ivCustomDialog = (ImageView) dialog.findViewById(R.id.ivCustomDialog); 

    Button dialogButton = (Button) dialog.findViewById(R.id.btnProsseguir); 
    dialogButton.setOnClickListener(new OnClickListener() {    
     @Override 
     public void onClick(View v) {           
      dialog.dismiss();     
     } 
    });    

    dialog.show();      
}

new Thread(){ 
    public void run(){ 
     int count = 0; 
     while(count < 100){ 
      if(count >= 100){              
       getActivity().runOnUiThread(new Runnable() {               
        @Override 
        public void run() {                
         showDialog(1); 
         interrupt(); 
        } 
       });               
      } 
      count++; 
     } 
    }           
}.start();

你確定你的代碼中有這個:'int count <0;'? – 2014-12-05 12:59:49

你想在'while(count <100)'中添加一些延遲嗎?爲什麼不使用'Thread.sleep'? – 2014-12-05 13:02:16
