How do you close/hide the Android soft keyboard programmatically?

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

I have two screens in my app.

  • First one has 2 EditText - 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 the Keyboard should be visible. This is my implementation (simplified by removing unnecessary/unrelated code).

#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. As I already mentioned, 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 startup.
  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 the exact opposite on both occasions. Hope someone faced this issue before. BTW I am testing on the simulator and HTC Desire phone.

#FINAL OUTCOME

Well, I got it working, with the help of all my 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);

The second answer is provided by @Dyarish, In fact, he linked to another SOF 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 EditTexts. 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 my other friends who tried to help me.

Solution 1

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

Solution 2

Adding this to your code android:focusableInTouchMode="true" will make sure that your keypad doesn't appear on startup for your edittext box. You want to add this line to your linear layout that contains the EditTextBox. You should be able to play with this to solve both your problems. I have tested this. Simple solution.

ie: In your app_list_view.xml file

<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> 

------------------ EDIT: To Make keyboard appear on startup -----------------------

This is to make they Keyboard appear on the username edittextbox on startup. All I've done is added an empty Scrollview to the bottom of the .xml file, this puts the first edittext into focus and pops up the keyboard. I admit this is a hack, but I am assuming you just want this to work. I've tested it, and it works fine.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    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" />
    <ScrollView
        android:id="@+id/ScrollView01"  
        android:layout_height="fill_parent"   
        android:layout_width="fill_parent"> 
    </ScrollView>
</LinearLayout>

If you are looking for a more eloquent solution, I've found this question which might help you out, it is not as simple as the solution above but probably a better solution. I haven't tested it but it apparently works. I think it is similar to the solution you've tried which didn't work for you though.

Hope this is what you are looking for.

Cheers!

Solution 3

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);
    }

Solution 4

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);
}
