為什么不顯示警報對話框？
[英]Why dosen't the alert dialog show?
問題描述
我有一個自定義對話框，它應該從用戶那里獲得一個值，但是它沒有顯示。 任何人都可以幫忙嗎？
這是我的代碼。

當我嘗試打開對話框時，會出現一個灰色屏幕，但是我沒有得到我的布局。 該對話框將在單擊回收站視圖的項目時打開我收到此錯誤消息：

我是 android 的新手，所以我不知道該怎么辦。 我還沒有找到這樣的東西。

“編輯點”對話框的問題是您沒有在顯示之前調用create 。 此外，您應該在正按鈕操作中添加花括號。
您應該將代碼編輯為：
new AlertDialog.Builder(this)
.setTitle("Edit Points")
.setMessage("You are editing your kids actions" +
"if you want to edit an action click edit. " +
"If you want to delete an action, press delete " +
"Click on the action you want to edit or delete")
.setPositiveButton("Edit", (dialog, which) -> {
new EnterReasonandValueDialogClass((dialog1, which1, mContext, et_reason, et_value) -> {
...
}
})
.setNegativeButton("Delete", (dialog, which) -> {
...
}).create().show();
警報對話框不顯示任何內容
