blocks|key|33758|text|为了回答我自己的问题，以防有人遇到同样的问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|33759|AutoCompleteTextView的一个特征是，如果您以编程方式更改它的文本，如果满足以下两个条件，它将下拉选择列表:+1.它具有焦点；2.列表超过30个项目。|33760|这种行为实际上是一个设计缺陷。当程序将文本设置为AutoCompleteTextView时，这意味着文本已经是正确的，没有点弹出过滤列表供用户进一步选择。|33761|actv.setText("Tim+Hortons");+
actv.setSelection(0,+actv.getText().length());+
actv.requestFocus();+
actv.dismissDropDown();++++//+doesn't+help+|code-block|syntax|javascript|33762|在上面的代码中，requestFocus()强制ACTV获得焦点，这会导致弹出下拉菜单。我尽量不要求焦点，而是在设置文本后调用clearFocus()。但是他的行为非常……不自然。dissmissDropdown()没有帮助，因为....我不知道，就是没用。所以，经过一番努力，我想出了这个变通办法：|33763|33764|初始化小部件时，我记起了类字段中的适配器。|ordered-list-item|33765|将上面的代码更改为：|33766|33767|mAdapter+=+(ArrayAdapter)actv.getAdapter()；//+mAdapter是一个类字段actv.setText("Tim+Hortons")；actv.setSelection(0，actv.getText().length())；actv.setAdapter((ArrayAdapter)null)；//关闭适配器actv.requestFocus()；处理程序=+new+handleMessage(){+public+void+Handler()+{ArrayAdapter+}；Message+msg+=+mHandler.obtainMessage()；msg.obj+=+actv；handler.sendMessageDelayed(msg，200)；//+200ms后重新打开|33768|这里的诀窍是将ACTV的适配器设置为空。由于没有适配器，系统当然不会弹出下拉列表。但该消息将在编程延迟200ms后将适配器重置回ACTV，ACTV将正常工作。|33769|这对我来说很有效！|33770|entityMap^0|0|0|0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|11|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|12|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|13|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|14|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|15|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|16|8|@]|9|@]|A|$]]|$1|N|3|O|5|P|7|17|8|@]|9|@]|A|$]]|$1|Q|3|R|5|P|7|18|8|@]|9|@]|A|$]]|$1|S|3|-4|5|6|7|19|8|@]|9|@]|A|$]]|$1|T|3|U|5|6|7|1A|8|@]|9|@]|A|$]]|$1|V|3|W|5|6|7|1B|8|@]|9|@]|A|$]]|$1|X|3|Y|5|6|7|1C|8|@]|9|@]|A|$]]|$1|Z|3|-4|5|6|7|1D|8|@]|9|@]|A|$]]]|10|$]]

To answer my own question in case someone had the same problem:

One characteristics of AutoCompleteTextView is that if you change its text programmatically, it will drop down the selection list if the following two conditions are met: 1. It has focus; 2. The list is longer than 30-something items. 

This behavior is actually, IMHO, a design flaw. When the program sets text to an AutoCompleteTextView, it would mean that the text is already correct, there is no point to popup the filtered list for user to further choose from. 

<pre><code>actv.setText("Tim Hortons"); 
actv.setSelection(0, actv.getText().length()); 
actv.requestFocus(); 
actv.dismissDropDown(); // doesn't help 
</code></pre>

In the above code, requestFocus() forces the ACTV to get the focus, and this causes the drop-down to pop up. I tried not to reqeuest focus, instead, I called clearFocus() after setting text. But the behavior is very .... unnatural. dissmissDropdown() doesn't help because .... I don't know, it just doesn't help. So, after much strugle, I came up with this work-around:

<ol>
<li>When initializing the widget, I remembered the adapter in a class field.</li>
<li>Change the above code to:

<pre><code>mAdapter = (ArrayAdapter&lt;String&gt;)actv.getAdapter(); // mAdapter is a class field 
actv.setText("Tim Hortons"); 
actv.setSelection(0, actv.getText().length()); 
actv.setAdapter((ArrayAdapter&lt;String&gt;)null); // turn off the adapter
actv.requestFocus();
Handler handler = new Handler() {
public void handleMessage(Message msg) {
 ((AutoCompleteTextView)msg.obj).setAdapter(mAdapter);
 };
Message msg = mHandler.obtainMessage();
msg.obj = actv;
handler.sendMessageDelayed(msg, 200); // turn it back on after 200ms
</code></pre></li>
</ol>

Here the trick is set the ACTV's adapter to null. Because there is no adapter, of course the system will not pop up the drop-down. But the message will reset the adapter back to the ACTV after the programmed delay of 200ms, and the ACTV will work normally as usual.

This works for me!

blocks|key|2181271|text|您还可以启用/禁用该下拉列表，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2181272|//+disable
actv.setDropDownHeight(0);

actv.setDropDownHeight(LayoutParams.WRAP_CONTENT);|code-block|syntax|javascript|2181273|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You can also enable/disable the drop-down like so:

<pre><code>// disable

actv.setDropDownHeight(LayoutParams.WRAP_CONTENT);
</code></pre>

blocks|key|1654615|text|您可以尝试以下步骤：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1654616|1654617|在设置文本时，还要将阈值设置为较大的值，这样下拉列表就不会出现。|ordered-list-item|1654618|1654619|actv.setThreshold(1000);|1654620|Then覆盖OnTouch以将阈值设置回1。|unordered-list-item|1654621|1654622|actv.setOnTouchListener(new+OnTouchListener()+{+@Override+public+boolean+onTouch(View+v，MotionEvent+event)+{+actv.setThreshold(1)；return+false；}}))；|1654623|entityMap^0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|R|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|S|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|T|8|@]|9|@]|A|$]]|$1|G|3|H|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|K|7|V|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|X|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|P|$]]

You can try these steps:

<ol>
<li>When setting the text, also set the Threshold value to a large value so that the dropdown doesnot come.

<pre><code> actv.setThreshold(1000);
</code></pre></li>
<li>Then override the OnTouch to set the threshold back to 1.

<pre><code> actv.setOnTouchListener(new OnTouchListener() {
 @Override
 public boolean onTouch(View v, MotionEvent event) {
 actv.setThreshold(1);
 return false;
 }
});
</code></pre></li>
</ol>

blocks|key|2177308|text|另一种解决方案是在设置文本之前清除焦点：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2177309|mContactTxt.setFocusable(false);

I too faced a scenario and I resolved in this way.

<ol>
<li>Store the values that you want to show, in a static way (Ex.POJO).</li>
<li>Check whether the stored static variable is not null and not empty.</li>
<li>if, its not empty / not null / its length greater than 0, set <code>dismissDropDown()</code> for that autocompleteTextView.</li>
</ol>

Please find the below snippet 

<pre><code>if(null != testText &amp;&amp; testText.length() != 0) {
 mAutoCompleteSearch.setText(incomingActivity.toString());
 mAutoCompleteSearch.dismissDropDown(); //Dismiss the drop down
 } else {
 mAutoCompleteSearchDocketActivity.setText("");
 // Here it(drop down) will be shown automatically
 }
</code></pre>

Hope, this would help for someone, Cheers !

 new int[] { android.R.id.text1 }, 0);

Maybe it is to late, but I've found elegant solution for this problem:

Disable filtering before setting text and enabling it after (instead of playing with focus or/and delays). You should use custom control in this case.

See example below:

<pre><code>public class CustomCompliteTextView extends AutoCompleteTextView {

 private boolean mIsSearchEnabled = true;

 public CustomCompliteTextView(Context context) {
 super(context);
 }

 public CustomCompliteTextView(Context context, AttributeSet attrs) {
 super(context, attrs);
 }

 public CustomCompliteTextView(Context context, AttributeSet attrs, int defStyle) {
 super(context, attrs, defStyle);
 }

 public void setSearchEnabled(boolean isEnabled) {
 mIsSearchEnabled = isEnabled;
 }

 @Override
 protected void performFiltering(CharSequence text, int keyCode) {
 if (mIsSearchEnabled) {
 super.performFiltering(text, keyCode);
 }
 }
}
</code></pre>

And usage:

<pre><code> text.setSearchEnabled(false);
 text.setText("Text you want to set");
 // optional, if you also want to set correct selection
 text.setSelection(text.getText().length());
 text.setSearchEnabled(true);
</code></pre>

<code>false</code> means that it is not filtering

blocks|key|3725566|text|在AppCompatAutoCompleteTextView中不能setTreshold()。如果使用AppCompatAutoCompleteTextView类，可以尝试这样做：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3725567|actv.setText("Tim+Hortons");
actv.setOnClickListener(new+View.OnClickListener()+{
++++++++@Override
++++++++public+void+onClick(View+v)+{
++++++++++++actv.setText("");
++++++++}
++++});|code-block|syntax|javascript|3725568|entityMap^0|1|T|X|D|1F|T|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|U|8|@]|D|@]|E|$]]]|L|$]]

In <code>AppCompatAutoCompleteTextView</code> can not <code>setTreshold()</code>. If use <code>AppCompatAutoCompleteTextView</code> class, can try this:

<pre><code>actv.setText("Tim Hortons");
actv.setOnClickListener(new View.OnClickListener() {
 @Override
 public void onClick(View v) {
 actv.setText("");
 }
 });
</code></pre>

blocks|key|3725601|text|我想你正在使用这种结构。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3725602|<TextInputLayout>

I suppose you are using this kind of structure
<pre><code>&lt;TextInputLayout&gt;
 &lt;AutoCompleteTextView/&gt;
&lt;/TextInputLayout&gt;
</code></pre>
To disable dropdown menu, you need to set <code>isEnabled</code> field to false only in <code>TextInputLayout</code>

I use the following code to set text to an AutoCompleteTextView field. But I noticed that when I set certain text (not all text, but some) to it, it will automatically pop up the drop-down. If I do not request focus, it would be better, but just better, not entirely all right. I tried dissmissDropDwon(), it doesn't help. So, Is there any way to stop the drop-down from showing up after setting text and focus to it?

<pre><code>actv.setText("Tim Hortons");
actv.setSelection(0, actv.getText().length());
actv.requestFocus();
actv.dismissDropDown(); // doesn't help
</code></pre>

Thank you!

我使用以下代码将文本设置为AutoCompleteTextView字段。但我注意到，当我设置某些文本(不是所有文本，而是一些文本)时，它会自动弹出下拉菜单。如果我不请求焦点，它会更好，但只是更好，并不完全正确。我尝试过dissmissDropDwon()，它不起作用。那么，在设置文本和焦点后，有什么方法可以阻止下拉菜单...
