問題描述
我有一個由 3 個 EditText 字段組成的活動(其中包括 TextViews 和一些按鈕).我還有一個 AutoCompleteTextView，其中包含使用 ArrayAdapter 的字符串列表.
I have an activity consisting of 3 EditText fields (amongst other things like TextViews and a few buttons). I also have an AutoCompleteTextView with a list of String's using an ArrayAdapter.
每當我在模擬器中測試應用程序時，我可以在鍵盤啟動時鍵入，但它不顯示文本(它仍然提供預測)，并且文本僅在鍵盤關閉后出現在 EditText 框中.當我在手機上測試它時也會發生這種情況.但是，如果屏幕鍵盤沒有啟動并且您只是正常輸入，它會在您在模擬器上輸入時顯示出來.
Whenever I test the app in an emulator, I can type when the keyboard is up but it doesn't show the text (it still gives predictions) and the text only appears in the EditText box once the keyboard is closed down. This happens when I test it on my phone, too. However, it works and shows up as you type on the emulator if the on-screen keyboard isn't up and you're just typing normally.
我不知道為什么！
這是我的活動 XML(EditText 是前 3 個塊)
Here is my Activity XML (where the EditText's are the top 3 blocks)
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>
這是我在活動中使用的代碼:(我已經刪除了不必要的代碼)
and here is the code I used in my activity: (I have stripped out unneccesary code)
public class MyWorkoutDiary1Activity extends Activity implements OnClickListener, TextWatcher
{
TextView seePrevious;
DatabaseHandler db;
AutoCompleteTextView myAutoComplete;
ArrayList<String> exerciseType = new ArrayList<String>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
exercise = new EditText(this);
exercise = (EditText)findViewById(R.id.inputExercise);
db = new DatabaseHandler(this);
exerciseType = db.getUniqueExercises();
myAutoComplete = (AutoCompleteTextView)findViewById(R.id.inputExercise);
myAutoComplete.addTextChangedListener(this);
myAutoComplete.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, exerciseType));
weight = new EditText(this);
weight = (EditText)findViewById(R.id.inputWeight);
reps = new EditText(this);
reps = (EditText)findViewById(R.id.inputReps);
}
}

推薦答案
好的，所以我找出了問題所在！
Ok, so I worked out what the issue was!
我沒有發布的代碼因為我認為它無關緊要"包含一個線程
The code which I didn't post because I thought it was 'irrelevant' contained a thread
public static Runnable updateTimerMethod = new Runnable()
{
public void run()
{
sessionTimer.setText(TimerHandler.theTime);
myHandler.postDelayed(this, 0);
}
};
通過將 postDelayed 設置為 0，我意識到線程基本上占用了所有活動(我真的不知道如何正確解釋).一旦我將其更改為... 100，然后 EditText工作.
I realised that the thread was basically taking up all of the activity (I don't really know how to explain that properly) by having the postDelayed as 0. Once I changed this to say... 100, then the EditText worked.
感謝幫助我的@NKN.
Thank you to @NKN who helped me.
這可能是針對我的，但希望這對其他人有所幫助.
This may be specific to me, but hopefully this will help somebody else.
