問題描述
我有一個帶有 Customer Text Watcher 的 EditText 字段.在一段代碼中，我需要使用 .setText("whatever").
I have an EditText field with a Customer Text Watcher on it. In a piece of code I need to change the value in the EditText which I do using .setText("whatever").
問題是，一旦我進行了更改，就會調用 afterTextChanged 方法，這會創建一個無限循環.如何在不觸發 afterTextChanged 的??情況下更改文本?
The problem is as soon as I make that change the afterTextChanged method gets called which created an infinite loop. How can I change the text without it triggering afterTextChanged?
我需要 afterTextChanged 方法中的文本，所以不建議刪除 TextWatcher.
I need the text in the afterTextChanged method so don't suggest removing the TextWatcher.
推薦答案
你可以注銷watcher，然后重新注冊.
You could unregister the watcher, and then re-register it.
或者，您可以設置一個標志，以便您的觀察者知道您何時自己更改了文本(因此應該忽略它).
Alternatively, you could set a flag so that your watcher knows when you have just changed the text yourself (and therefore should ignore it).
