顯示自定義對話框一個Android AlertDialog，點擊

我建立一個AlertDialog這說明三個項目：顯示自定義對話框一個Android AlertDialog，點擊

AlertDialog.Builder builder = new AlertDialog.Builder(myActivity); 
... 
builder.setItems(items, new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int item) { 
         if(item==0){ //do stuff} 
            else if(item==1){//do other stuff} 
            else if(item==2){//show other dialog} 
...

現在我想，當用戶選擇第三項（項目顯示另一個對話框== 2 ）。我的做法是這樣的：

Dialog otherDialog = new Dialog(myActivity.savedApplicationContext); 
otherDialog.setContentView(R.layout.other_layout); 
otherDialog.setTitle(getString(R.string.update_dialog)); 
dialog.dismiss(); //dismiss old dialog 
otherDialog.show();

這不工作:(拋出的異常：

我已經搜查計算器/在INET但被meantioned解決方案有通過活動到對話框的applicationContext（我在此情況下那樣，我保存在一個專用變量的所述activitys的applicationContext的參考：myActivity.savedApplicationContext

固定的問題

而不是 savedApplicationContext = getApplicationContext（）;我使用 savedApplicationContext = this;

現在它工作:-)
