Android-prevent Dismissal Of Dropdown In Autocompletetextview After Item Selection

Even though I'm setting the setOnItemClickListener on the AutoCompleteTextView and performing some custom operations in it, once that method is done, the list dismisses and prints

Solution 1:

I also want to implement the same i used below code to implement it.

Create a custom class and extend AutoCompleteTextView.

Override dismissDropDown() method and remove the super call from it. Will work for you.

publicclassCustomAutoCompleteextendsAutoCompleteTextView {
    publicNoSelectionAutoComplete(Context context) {
        super(context);
    }

    publicNoSelectionAutoComplete(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    publicNoSelectionAutoComplete(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @OverrideprotectedvoidreplaceText(CharSequence text) {

    }

    @OverridepublicvoiddismissDropDown() {

    }
}

Solution 2:

I added an onClickListener to the entire custom row layout that I was using for the dropdown adapter. This way whenever the row is clicked, my row onClickListener is invoked and the default one for the dropdown is not.

Solution 3:

First Question - Prevent dropdown dismissal:

Solved below.

Second Question - Prevent text replacement: (For others interested)

You can extend AutoCompleteTextView and override

protectedvoidreplaceText(CharSequence text) {}

to do nothing.

As others mentioned, overriding performCompletion() won't help here.

Solution 4:

well at least it seems like they are planning to add this in near future.

/**
 * Sets whether the drop-down should remain visible as long as there is there is
 * {@link #enoughToFilter()}.  This is useful if an unknown number of results are expected
 * to show up in the adapter sometime in the future.
 *
 * The drop-down will occupy the entire screen below {@link #getDropDownAnchor} regardless
 * of the size or content of the list.  {@link #getDropDownBackground()} will fill any space
 * that is not used by the list.
 *
 * @param dropDownAlwaysVisible Whether to keep the drop-down visible.
 *
 * @hide Pending API council approval
 */publicvoid setDropDownAlwaysVisible(boolean dropDownAlwaysVisible) {
    mPopup.setDropDownAlwaysVisible(dropDownAlwaysVisible);
}

edit,new answer: this worked for me but it closes for a sec,and opens again.

classtaskextendsTimerTask {

            @Overridepublicvoidrun() {
                runOnUiThread(newRunnable() {

                    @Overridepublicvoidrun() {
                        autoComplete.showDropDown();
                    }
                });
            }
       };
    autoComplete.setOnItemClickListener(newOnItemClickListener() {

        publicvoidonItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {

             newTimer().schedule(newtask(),0, 10);
        }

    });
