POEmpty space when I return to Activity (Soft Keyboard forced)
text
Body
copied!<p>I have an <code>ActionView</code> with menu item on <code>ActionBar</code> (using <em>ActionBarSherlock</em>), I'm able to display an <code>EditText</code> as a search field in it. It's an input to launch another <code>Activity</code> with a <code>CustomView</code> in ActionBar which it displays the same layout (I don't use anything to force the <code>SoftKeyboard</code> to appear in this second activity, there is no problem here). When I want to make the Soft Keyboard appears/disapears automatically when the view collapse in first activity, I use: </p> <p><strong>openKeyboard method</strong> </p> <pre><code>mImm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY); </code></pre> <p><strong>closeKeyboard method</strong> </p> <pre><code>mImm.hideSoftInputFromWindow(edittext.getWindowToken(), 0); </code></pre> <p>I use the <code>ActionExpandListener</code> to make the SoftKeyboard appears or disappears when the <code>View</code> expands or collapse. With these two methods above, I have the expected result. I found this on several questions on SO (especially on <a href="https://stackoverflow.com/questions/1109022/close-hide-the-android-soft-keyboard">Close/hide the Android Soft Keyboard</a> and <a href="https://stackoverflow.com/a/15225311/2668136">Showing the soft keyboard for SearchView on ActionBar</a> or <a href="https://stackoverflow.com/questions/2479504/forcing-the-soft-keyboard-open">Forcing the Soft Keyboard open</a>).</p> <p>Just to understand, when I used <code>SHOW_IMPLICIT</code> or <code>SHOW_FORCED</code> alone, it was no effect on lower versions (as 2.+). The EditText was focused but the keyboard didn't show up (so, you guess it was a bad thing). In recent versions (as 4.+ for example), it was a nice effect and no problem. Then, I forced keyboard to show up with the <em>openKeyboard method</em> above.</p> <p>Now, I got some troubles with this...<br> On lower versions, I got "empty" space before and after the keyboard created/destroyed, I can live with this. <strong>BUT</strong> in recent versions, I got "empty" space which it displays when I <strong>return to the first Activity</strong>. And it's here during less than one second, but sufficient to see that!<br> To better understand what happens, see the image below: </p> <p><img src="https://i.stack.imgur.com/hliIx.png" alt="Left=Second Activity: I press the Up Home Button - the keyboard disappears properly. Right=(back to) First Activity: my ListView is covered by a "empty" screen (background color in my application) and it disappears."> </p> <p><strong><em>1.</em></strong> Second Activity: I press the Up Home Button - the keyboard disappears properly.<br> <strong><em>2.</em></strong> (back to) First Activity: my ListView is covered by a "empty" space (background color in my application). And it disappears <em>(this is the same height of the SoftKeyboard, no possible doubt!)</em> </p> <p>I guess it's because <strong>I forced the keyboard to appear</strong> in my first activity <strong>although I also forced the keyboard to hide</strong> when I go the second, but how can I resolve the "empty" space when I return to the first activity?</p> <hr> <p><em>Summary</em><br> 1) A activity => press item in menu > view collapse > show the keyboard > tap text > send it > hide keyboard > launch B activity.<br> 2) B activity => setCustomView in actionbar > show the keyboard only if the edittext is focused/clicked > tap text > send it > hide keyboard > refresh content > press home button > return to A activity<br> 3) A activity => "empty" screen > screen disappears. </p> <p>Any help will be very appreciate.<br> Thanks for your time. </p> <hr> <p><strong>EDIT</strong><br> I add my code of my first class, to see if someone tells me what I'm doing wrong. Maybe it's my code which makes the issue. </p> <blockquote> <p><strong>Menu (ActionView)</strong> </p> </blockquote> <pre><code>ActionBar actionBar; MenuItem itemSearchAction; EditText mSearchEdit; InputMethodManager mImm; @Override public boolean onCreateOptionsMenu(final Menu menu) { getSupportMenuInflater().inflate(R.menu.main, menu); itemSearchAction = menu.findItem(R.id.action_search); View v = (View) itemSearchAction.getActionView(); mSearchEdit = (EditText) v.findViewById(R.id.SearchEdit); itemSearchAction.setOnActionExpandListener(this); return true; } </code></pre> <blockquote> <p><strong>OnActionExpandListener</strong> </p> </blockquote> <pre><code>@Override public boolean onMenuItemActionExpand(MenuItem item) { actionBar.setIcon(R.drawable.ic_app_search); // change icon mSearchEdit.requestFocus(); // set focus on edittext openKeyboard(); // the method above mSearchEdit.setOnEditorActionListener(new OnEditorActionListener() { @Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { if (actionId == EditorInfo.IME_ACTION_SEARCH || (event != null && event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) { closeKeyboard(); // same method as above // new Intent() to second activity // perform with startActivity(); itemSearchAction.collapseActionView(); // collapse view return true; } return false; } }); // add a clicklistener to re-open the keyboard on lower versions mSearchEdit.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { openKeyboard(); } }); return true; } @Override public boolean onMenuItemActionCollapse(MenuItem item) { actionBar.setIcon(R.drawable.ic_app_logo); // change icon again if(!(mSearchEdit.getText().toString().equals(""))) mSearchEdit.setText(""); // reinitial the edittext return true; } </code></pre> <blockquote> <p><strong>OnOptionsItemSelected</strong> </p> </blockquote> <pre><code>// I had this verification when I make new Intent() to // a new activity, just in case (works like a charm) if(itemSearchAction.isActionViewExpanded()) itemSearchAction.collapseActionView(); </code></pre> <blockquote> <p><strong>ActionView (Item + layout)</strong> </p> </blockquote> <pre><code><item android:id="@+id/action_search" android:icon="@drawable/ic_app_search" android:title="@string/action_search" android:showAsAction="ifRoom|collapseActionView" android:actionLayout="@layout/search_actionview" /> <EditText xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/SearchEdit" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="right|bottom" android:gravity="left" android:layout_marginBottom="6dip" android:hint="@string/action_search" android:textColor="@color/white" android:textColorHint="@color/white" android:singleLine="true" android:cursorVisible="true" android:inputType="text" android:imeOptions="actionSearch|flagNoExtractUi" android:imeActionLabel="@string/action_search" android:focusable="true" android:focusableInTouchMode="true" android:background="@drawable/bt_edit_searchview_focused" > <requestFocus /> </EditText> </code></pre> <hr> <p><strong>UPDATE</strong> </p> <p>I see a lot of similar issues, with <code>EditText</code> in <code>ActionBar</code> which not makes the keyboard appear even the focus has set. I tried this again (even if I already tested several time): </p> <pre><code>/* * NOT WORKING * Sources: https://stackoverflow.com/questions/11011091/how-can-i-focus-on-a-collapsible-action-view-edittext-item-in-the-action-bar-wh * https://stackoverflow.com/a/12903527/2668136 */ int mode = WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE; getWindow().setSoftInputMode(mode); postDelayed() to show: .showSoftInput(mSearchEdit, InputMethodManager.SHOW_IMPLICIT); - 200ms (Not working on lower versions) postDelayed() to hide: .hideSoftInputFromWindow(mSearchEdit.getWindowToken(), 0); - 200ms new Runnable() on edittext => requestFocus() + showSoftInput(SHOW_IMPLICIT/FORCED/HIDE_NOT_ALWAYS/HIDE_IMPLICIT_ONLY) </code></pre> <p>It seems with me, only <code>SHOW_FORCED|HIDE_IMPLICIT_ONLY</code> can force the keyboard to show automatically when the view collapse. After this, in all versions, I must to make a <code>hideSoftInputFromWindow</code> to 0 for hiding it.<br> <strong>BUT</strong> this undisplays the keyboard even if the edittext is pressed, so I added an <code>ClickListener</code> to force the keyboard to show again (this happens only on lower versions). </p> <hr> <p><strong>UPDATE2:</strong><br> It's clearly weird, when I try to make a little <code>Thread</code> like I saw in many SO answers (with/without ABS), nothing happens in lower versions.<br> I tried a different way. I created the new thread to have a short time before call the new intent for hide the keyboard. I had the keyboard which forced to close, OK. And then I opened the new activity, OK. But now when I return, it's worth! The "empty" space is also on lower versions when I come back. I did this: </p> <pre><code>// close the keyboard before intent closeKeyboard(); // make the intent after 500 ms Handler handler = new Handler(); Runnable runner = new Runnable() { public void run() { // new intent with startActivity() } }; handler.postDelayed(runner, 500); // collapse the View itemSearchAction.collapseActionView(); </code></pre> <p>It gives me headaches! I don't understand why in my case, the tip above not working whereas on other answers, when they use a new thread to show/hide the keyboard, this works perfectly.</p> <p><strong>NOTE:</strong> my tests were on <em>(emulator:)</em> GalaxyNexus, NexusS, NexusOne and <em>(real devices:)</em> Samsung GalaxySL (2.3.6) and Nexus4 (4.4). </p> <p>If someone can help me with this ugly situation. Thanks in advance.</p>
