[java] Programmatically Hide/Show Android Soft Keyboard

Possible Duplicate:
Close/hide the Android Soft Keyboard

First thing first I already saw this thread. I tried accepted methods given there..But nothing worked for me..

I have two screens in my app.

• First one have 2 EditText's - One for username and one for password
• Second one have one ListView, and an EditText - to filter the listView

In my first screen, I want username EditText to have focus on startup and Keyboard should be visible..This is my implementation (simplified by removing unnecessary/unrelated codes)..

app_login.xml

<LinearLayout android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:paddingLeft="20dip"  
    android:paddingRight="20dip">

    <EditText android:id="@+id/username" 
        android:singleLine="true" 
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content" android:hint="Username"  
        android:imeOptions="actionDone" android:inputType="text"
        android:maxLines="1"/>

    <EditText android:id="@+id/password" 
        android:password="true" 
        android:singleLine="true"  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"    
        android:hint="Password" />
</LinearLayout>

AppLogin.java

class AppLogin extends Activity{
    private EditText mUserNameEdit = null;
    private EditText mPasswordEdit = null;

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.app_login);

        mUserNameEdit  =    (EditText) findViewById(R.id.username);
        mPasswordEdit  =    (EditText) findViewById(R.id.password);

        /* code to show keyboard on startup.this code is not working.*/
        InputMethodManager imm =  (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);

    }//End of onCreate()
}

Well, the keyboard is not showing at startup. And my design badly requires a keyboard there.

Now on to second page..I already said I have a listView and EditText there..I want my keyboard to be hidden on startup only to appear when the user touches the editText..Can you believe it? whatever I tried soft Keyboard is showing when I load the activity..I am not able to hide it.

app_list_view.xml

<LinearLayout android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" >

   <EditText android:id="@+id/filter_edittext"       
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Search" android:inputType="text" 
        android:maxLines="1"/>
    <ListView android:id="@id/android:list" 
        android:layout_height="fill_parent"
        android:layout_weight="1.0" 
        android:layout_width="fill_parent" 
        android:focusable="true" 
        android:descendantFocusability="beforeDescendants"/>
</LinearLayout>     

AppList.java

public class MyListActivity extends ListActivity{
   private EditText mfilterEditText;

    @Override
   public void onCreate(Bundle savedInstanceState) {        
      super.onCreate(savedInstanceState);
      setContentView(R.layout.app_list_view);

      mFilterEditText  =  (EditText) findViewById(R.id.filter_edittext);
      InputMethodManager imm = InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
      imm.hideSoftInputFromWindow(mFilterEditText.getWindowToken(), 0);
   }
}

To simplify

1. On Login Page (first Page) I want my keyboard to be visible on start up.
2. On SecondPage I want the keyboard to be hidden first, only to appear when the user touches editText

And my problem is I am getting exact opposite on both occasion...Hope someone faced this issue before.BTW I am testing on simulator and HTC Desire phone.

FINAL OUTCOME

Well, I got it working, with the help of all friends here.

1. To Show keyboard on startup

Two answers worked for me. One provided by @CapDroid, which is to use a handler and post it delayed..

mUserNameEdit.postDelayed(new Runnable() {
  @Override
  public void run() {
    // TODO Auto-generated method stub
    InputMethodManager keyboard = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    keyboard.showSoftInput(mUserNameEdit, 0);
  }
},50);

Second answers are provided by @Dyarish, In fact, he linked to another SO thread, which I haven't seen before. But the funny thing is that this solution is given in the thread which I referenced at the start. And I haven't tried it out because it had zero votes in a thread where all other posts have plenty of votes..Height of foolishness..

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

For me, the second solution looked neat, so I decided to stick with it..But the first one certainly works. Also, @Dyarish's answer contains a clever hack of using a ScrollView below EditText to give EditText the focus..But I haven't tried it, but it should work. Not neat though..

2. To hide keyboard at activity start

Only one answer worked for me, which is provided by @Dyarish. And the solution is to use focusableInTouchMode settings in xml for the layout containing the editText's. This did the trick

<LinearLayout android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:focusableInTouchMode="true">
    <EditText android:id="@+id/filter_edittext"       
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Search" android:inputType="text" 
        android:maxLines="1"/>
    <ListView android:id="@id/android:list" 
        android:layout_height="fill_parent"
        android:layout_weight="1.0" 
        android:layout_width="fill_parent" 
        android:focusable="true" 
        android:descendantFocusability="beforeDescendants"/>
</LinearLayout> 

Anyway, I end up using Dyarish's answer in both cases. So I am awarding the bounty to him..Thanks to all other friends who tried to help me..

Did you try InputMethodManager.SHOW_IMPLICIT in first window.

and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY

EDIT :

If its still not working then probably you are putting it at the wrong place. Override onFinishInflate() and show/hide there.

@override
public void onFinishInflate() {
     /* code to show keyboard on startup */
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}

UPDATE 2

@Override
    protected void onResume() {
        super.onResume();
        mUserNameEdit.requestFocus();

        mUserNameEdit.postDelayed(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                InputMethodManager keyboard = (InputMethodManager)
                getSystemService(Context.INPUT_METHOD_SERVICE);
                keyboard.showSoftInput(mUserNameEdit, 0);
            }
        },200); //use 300 to make it run when coming back from lock screen
    }

I tried very hard and found out a solution ... whenever a new activity starts then keyboard cant open but we can use Runnable in onResume and it is working fine so please try this code and check...

UPDATE 1

add this line in your AppLogin.java

mUserNameEdit.requestFocus();

and this line in your AppList.java

listview.requestFocus()'

after this check your application if it is not working then add this line in your AndroidManifest.xml file

<activity android:name=".AppLogin" android:configChanges="keyboardHidden|orientation"></activity>
<activity android:name=".AppList" android:configChanges="keyboard|orientation"></activity>

ORIGINAL ANSWER

 InputMethodManager imm = (InputMethodManager)this.getSystemService(Service.INPUT_METHOD_SERVICE);

for hide keyboard

 imm.hideSoftInputFromWindow(ed.getWindowToken(), 0); 

for show keyboard

 imm.showSoftInput(ed, 0);

for focus on EditText

 ed.requestFocus();

where ed is EditText

Try this code.

For showing Softkeyboard:

InputMethodManager imm = (InputMethodManager)
                                 getSystemService(Context.INPUT_METHOD_SERVICE);
if(imm != null){
        imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);
    }

For Hiding SoftKeyboard -

InputMethodManager imm = (InputMethodManager)
                                  getSystemService(Context.INPUT_METHOD_SERVICE);
if(imm != null){
        imm.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);
    }
