Android: AutoCompleteTextView hide soft keyboard

问题

I have an AutoCompleteTextView which as usual provides suggestions after a user types 3 letters. I want once once I touch the suggestion list to hide the soft keyboard. What I have done below with the table layout hides the keyboard only when clicking anywhere but the suggestion list.

XML

<TableRow
    android:id="@+id/tableRow2"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center" >

    <AutoCompleteTextView
        android:id="@+id/auto_insert_meds"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:ems="15"
        android:inputType="textVisiblePassword|textMultiLine"
        android:scrollHorizontally="false"
        android:text=""
        android:textSize="16sp" />
</TableRow>

Java

TableLayout tbl = (TableLayout) findViewById(R.id.main_table);
tbl.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        in.hideSoftInputFromWindow(v.getWindowToken(), 0);
        return true;
    }
});

XML for custom list

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/medlist_linear_layout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

        <TextView
        android:id="@+id/med_name"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:scrollHorizontally="false"
        android:padding="3dp"
        android:textColor="@android:color/white" />

</LinearLayout>

回答1:

Use OnItemClickListener. Hope this works :)

AutoCompleteTextView text = (AutoCompleteTextView) findViewById(R.id.auto_insert_meds);

text.setOnItemClickListener(new OnItemClickListener() {

  @Override
  public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
    InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    in.hideSoftInputFromWindow(arg1.getWindowToken(), 0);

  }

});

UPDATED

Use this

in.hideSoftInputFromWindow(arg1.getApplicationWindowToken(), 0);

instead of -

in.hideSoftInputFromWindow(arg1.getWindowToken(), 0);

As chakri Reddy Suggested:

It's working for me I just replaced

this:

 in.hideSoftInputFromWindow(arg1.getWindowToken(), 0);

with:

 in.hideSoftInputFromWindow(arg1.getApplicationWindowToken(), 0);

回答3:

1) Change AutoCompleteTextView dropdown height to MATCH_PARENT

setDropDownHeight(LinearLayout.LayoutParams.MATCH_PARENT);

2) Dismiss soft keyboard by overriding getView() of AutoCompleteTextView adapter

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    View v = super.getView(position, convertView, parent);
    v.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                InputMethodManager imm = (InputMethodManager) getActivity()
                        .getSystemService(
                                Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(
                        typeTextView.getWindowToken(), 0);
            }

            return false;
        }
    });

    return v;
}

Found this chunk of code in a similar thread. Hope it helps:

    private void hideKeyboard() {   
        // Check if no view has focus:
        View view = this.getCurrentFocus();
        if (view != null) {
            InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
            inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
        }
}

In case this helps anyone, I had a similar situation.

My AutoCompleteTextView was displayed on a DialogFragment with no Title Bar because I used getWindow().requestFeature(Window.FEATURE_NO_TITLE); in onCreateDialog()

I added the following line after FEATURE_NO_TITLE and the results list displayed over the keyboard:

@Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialogo=super.onCreateDialog(savedInstanceState);
        dialogo.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        dialogo.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
        return dialogo;
    }

AutoCompleteTextView autoText= (AutoCompleteTextView) findViewById(R.id.auto_insert_meds);

autoText.setOnItemClickListener(new OnItemClickListener() {
  @Override
  public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
    View view = this.getCurrentFocus();
    if (view != null) {
        InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
        inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

    }
  }
});

Try this guys..It will work..!!!

 AutoCompleteTextView auto_text = (AutoCompleteTextView)findViewById(R.id.auto_insert_meds);

 auto_text.setOnItemClickListener(new OnItemClickListener() {

 @Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) 
{
   InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

   in.hideSoftInputFromWindow(arg1.getApplicationWindowToken(), 0);

} });

I used the TextWatcher already to detect when the user has typed in at least 3 letters (which triggers a download API) as follows:

    searchAutoComplete.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // when the user has clicked on an item in the list, it will trigger onTextChanged.
            // To avoid querying the server and showing the dropdown again, use searchAutoComplete.isPerformingCompletion()
            if (!searchAutoComplete.isPerformingCompletion()){
                if (s != null && s.length() >= 3) {
                    downloadSearchResults(s.toString());
                } else {
                    searchAutoComplete.dismissDropDown();// hide dropdown after user has deleted characters and there's less than 3 visible
                }
            } else {
                // user has clicked on a list item so hide the soft keyboard
                InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                if (in != null) in.hideSoftInputFromWindow(searchAutoComplete.getApplicationWindowToken(), 0);
            }
        }

        @Override
        public void afterTextChanged(Editable s) { }
    });
