Change keyboard's text pad with number pad

I have EditText and input type is textNoSuggestions.
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_marginTop="5dp">
<EditText
android:id="#+id/firstName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="Name"
android:inputType="textNoSuggestions" />
</android.support.design.widget.TextInputLayout>
Also i have one button and in button onclick method i try to change keyboard's input type.This is a source
final Button changeKeyboard = (Button) dialog.findViewById(R.id.change_keyboard);
changeKeyboard.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
firsName.setRawInputType(InputType.TYPE_CLASS_NUMBER);
}
});
Is it a possible to change keyboards' input type in button click when keyboard is showing?
How i can solve my problem thanks everyone

set is setTransformationMethod(), not setInputType(). So something like:
firstName.setTransformationMethod(numberTransformationMethod.getInstance());

On your code, change:
firsName.setRawInputType(InputType.TYPE_CLASS_NUMBER);
to this (firstName with "t", the name on your xml):
firstName.setRawInputType(InputType.TYPE_CLASS_NUMBER);
Also, you positively can change your keyboard calling setInputType, like this: firstName.setInputType(x), where x is an int and can be 1 (alfanumeric); 2 (numeric) or 3 (phone like).
EDIT:
You can hide your keyboard calling this on your activity:
public static void hideKeyboard(Activity activity) {
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
//Find the currently focused view, so we can grab the correct window token from it.
View view = activity.getCurrentFocus();
//If no view currently has focus, create a new one, just so we can grab a window token from it
if (view == null) {
view = new View(activity);
}
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

firsName.setInputType(InputType.TYPE_CLASS_NUMBER);

Editview press softkey Return, lose focus AND hide keyboard, how?

I'm working on an Android app and I've got 2 editviews and a label. The user can enter 2 values and the label shows some calculation using input from the editviews. What I want is the following;
user enters either value with soft-keyboard
user presses "Return" softkey
editview should lose focus
the soft-keyboard should disappear
textview label should be recalculated
Now, the v.clearFocus only seems to works when there is another widget that can can get focus(?), so I've also added a dummie zero-pixel layout that can 'steal' the focus from the first editview. The Return key works now, but when the user switches focus from edit1 to edit2 by simply tapping then HideKeyboard() crashes. I've tried checking if inputMethodManager==null but that didn't help.
This all feels like I'm hacking to trick Android into doing some common UI behaviour, so I can't help but think that I'm overlooking something here.
Any help would be greatly appreciated. Btw I know this is similar to this question: How to lose the focus of a edittext when "done" button in the soft keyboard is pressed?
But I've tried that and it doesn't work.
So my layout xml is this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- Dummy control item so that first textview can lose focus -->
<LinearLayout
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_width="0px"
android:layout_height="0px"/>
<EditText
android:id="#+id/editTest1"
android:layout_width="250px"
android:layout_height="wrap_content"
android:inputType="numberDecimal"
android:imeOptions="actionDone" >
</EditText>
<EditText
android:id="#+id/editTest2"
android:layout_width="250px"
android:layout_height="wrap_content"
android:inputType="numberDecimal"
android:imeOptions="actionDone" >
</EditText>
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="test123" />
</LinearLayout>
And the source is this:
public class CalcActivity extends Activity implements OnFocusChangeListener {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab2_weight);
EditText testedit = (EditText) findViewById(R.id.editTest1);
testedit.setOnFocusChangeListener(this);
testedit.setOnEditorActionListener(new OnEditorActionListener() {
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if(actionId==EditorInfo.IME_ACTION_DONE){
//Clear focus here from edittext
Log.d("test app", "v.clearFocus only works when there are other controls that can get focus(?)");
v.clearFocus();
}
return false;
}
});
}
public void hideSoftKeyboard() {
InputMethodManager inputMethodManager = (InputMethodManager) this.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);
}
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus == false) {
Log.d("unitconverter", "onFocusChange hasFocus == false");
// update textview label
TextView bla = (TextView) findViewById(R.id.textView1);
bla.setText(String.format("%s + %s", (((EditText) findViewById(R.id.editTest1)).getText()), (((EditText) findViewById(R.id.editTest2)).getText())));
// hide keyboard
hideSoftKeyboard();
}
}
}

EditText onClick not shows Virtual Keyboard

If i click on my EditText, the virtual keyboard simple not shows up. The cursor is shown, but no keyboard to type on.
I even tried it with manually open but just no works.
Here is my code:
public class CreateNote extends Activity {
EditText titleEdit;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.createnote);
titleEdit = (EditText) findViewById(R.id.titleEdit);
titleEdit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
InputMethodManager imm = (InputMethodManager) CreateNote.this
.getSystemService(Service.INPUT_METHOD_SERVICE);
imm.showSoftInput(titleEdit, 0);
}
});
}
}
Snippet of Layout:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#989898" >
<EditText
android:id="#+id/titleEdit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/edittextdrawale"
android:ems="10"
android:textColor="#fff"
android:textColorHint="#fff" >
<requestFocus />
</EditText>
</FrameLayout>
What could be the reason of playing hide and seek of my virtual keyboard ?
I test on real device, not on emulator.

Try with this, it worked for me.
EditText etHorseName = (EditText) getView().findViewById(R.id.horseName);
etHorseName.clearFocus();
in onCreate() or where you want.

Late answer but here is how to solve it without adding code, just remove this from your XML:
<requestFocus />
No idea why the keyboard does not show up when this is set... It does show up however if you first loose the focus and then click on the edit text. I had the problem on Android 2.3.6 but it worked on 4.1.2, so maybe it was an early bug.

It is just a default behavior , you not suppose to do it manually, remove below part from your code.
titleEdit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
InputMethodManager imm = (InputMethodManager) CreateNote.this
.getSystemService(Service.INPUT_METHOD_SERVICE);
imm.showSoftInput(titleEdit, 0);
}
});

Try to hide and show the keyboard with this code:
InputMethodManager imm = (InputMethodManager) this.getSystemService(Service.INPUT_METHOD_SERVICE);
// To show keyboard
imm.showSoftInput(titleEdit, 0);
// To hide keyboard
imm.hideSoftInputFromWindow(titleEdit.getWindowToken(), 0);

Trying to get Android keyboard to popup on activity startup

I want the Android Keyboard to pop-up on the startup of my activity. A simple google search shows that you just have to requestFocus which I do in my .xml, but it still doesn't pop up. Am I making any minor mistake that is causing this not to work?
Testing on:
Physical 4.1
Emulator 2.2
layout.xml:
<EditText
android:id="#+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:ems="10"
android:hint="To:"
android:inputType="textPersonName" >
<requestFocus />
</EditText>

This works:
myEditText.setOnFocusChangeListener( new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
}
}
});

Try this code:
EditText input = (EditText) findViewById(R.id.editText1);
InputMethodManager inputManager = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.showSoftInput(input, InputMethodManager.SHOW_IMPLICIT);

Disable soft keyboard on NumberPicker

I'm trying to deactivate the soft keyboard when using a NumberPicker to enter numerical values (for aesthetic reasons). This is my layout-xml-code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="30dp"
android:layout_marginTop="30dp" >
<NumberPicker
android:id="#+id/repetitionPicker"
android:layout_width="40dp"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="#string/repetitions_short_divider"
android:textAppearance="?android:attr/textAppearanceMedium" />
<NumberPicker
android:id="#+id/weightPicker"
android:layout_width="40dp"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="#string/pounds"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
<Button
android:id="#+id/saveButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="#string/save" />
</LinearLayout>
And finally this is the code where I try to block the keyboard in the onCreate()-method:
// hide keyboard
View.OnClickListener disableKeyBoardListener = new View.OnClickListener() {
public void onClick(View v) {
((InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE))
.hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
};
((EditText) weightPicker.getChildAt(1)).setInputType(InputType.TYPE_NULL);
((EditText) repetitionPicker.getChildAt(1)).setInputType(InputType.TYPE_NULL);
((EditText) weightPicker.getChildAt(1)).setOnClickListener(disableKeyBoardListener);
//((EditText) repetitionPicker.getChildAt(1)).setOnClickListener(disableKeyBoardListener);
//weightPicker.setOnClickListener(disableKeyBoardListener);
//repetitionPicker.setOnClickListener(disableKeyBoardListener);
getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
Sadly, the soft keyboard still shows up when clicking on a NumberPicker. Any ideas?

Just found this and it works like a charm:
myNumberPicker.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS);
You can also set this in XML:
android:descendantFocusability="blocksDescendants"

Xml version of Andrew Webber's answer
android:descendantFocusability="blocksDescendants"
Example
<NumberPicker
android:id="#+id/your_numberpicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:descendantFocusability="blocksDescendants"/>

After reading through the com/android/internal/widget/NumberPicker.java source code i got to the following solution:
// Hide soft keyboard on NumberPickers by overwriting the OnFocusChangeListener
OnFocusChangeListener fcl = new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
// Do nothing to suppress keyboard
}
};
((EditText) numberPicker.getChildAt(1)).setOnFocusChangeListener(fcl);
// Suppress soft keyboard from the beginning
((EditText) numberPicker.getChildAt(1)).setInputType(InputType.TYPE_NULL);

Just enhanced the #MaxVogler 's ans (so if wannt vote this vote #MaxVogler too) and make it a robust hack. Also we dont need to call setOnFocusChangeListener and setInputType. Only setFocusable to false will do.
Below is a helper api to enable/disable the feature
public static void enableNumberPickerManualEditing(NumberPicker numPicker,
boolean enable) {
int childCount = numPicker.getChildCount();
for (int i = 0; i < childCount; i++) {
View childView = numPicker.getChildAt(i);
if (childView instanceof EditText) {
EditText et = (EditText) childView;
et.setFocusable(enable);
return;
}
}
}

Here's another way to do it which enables the user still to edit a number if they want to - it just suppresses the soft keyboard initially. Use NumberPicker.setDescendantFocusability(FOCUS_BLOCK_DESCENDANTS) to suppress the soft keyboard when the interface first shows as per answers above. Then get your dialog or activity to implement View.OnTouchListener, call setOnTouchListener(this) on your NumberPicker, and in your implementation of onTouch(View v,MotionEvent e) reset the numberpicker descendant focusability to its normal value, then return false.
Returning false means that the touch is still processed by the NumberPicker, which means that if the user taps the edit box the soft keyboard comes up. This happens to be exactly what I wanted faced with the same problem - having the soft keyboard come up with the dialog when it first shows is displeasing as it shifts the dialog up after it appears.
public class GetBufferDialog extends DialogFragment implements View.OnTouchListener {
after creating the Dialog in the onCreateDialog() method and finding the NumberPicker:
m_oldFocus = m_numberpicker.getDescendantFocusability();
m_numberpicker.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS);
m_numberpicker.setOnTouchListener(this);
and here's the OnTouch method:
public boolean onTouch(View v, MotionEvent event) {
m_numberpicker.setDescendantFocusability(m_oldFocus);
return false;
}

Working code
Programatically :
mp.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS);
XML:
android:descendantFocusability="blocksDescendants"

I don't know why it works, but setting OnClickListener which does nothing prevented keyboard from showing (Lollipop)
numberPicker.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});

The simplest I found to work was :
numberPicker = (NumberPicker) myDialogView.findViewById(R.id.myViewId);
EditText numberPickerChild = (EditText) numberPicker.getChildAt(0);
numberPickerChild.setFocusable(false);
numberPickerChild.setInputType(InputType.TYPE_NULL);

If you only want to hide the software keyboard when loading the view with your number picker, but still want the users to be able to edit after the view loads, then you shouldn't block descendant focusability. Instead, just prevent the number picker from being the first focused item in your view.
See this answer for details.
Based on the above answer:
<!-- Dummy item to prevent Number Picker from receiving focus -->
<LinearLayout
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_width="0px"
android:layout_height="0px"/>
<!-- :nextFocusUp and :nextFocusLeft have been set to the id of this component
to prevent the dummy from receiving focus again -->
<NumberPicker
android:id="#+id/number_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:nextFocusUp="#id/number_picker"
android:nextFocusLeft="#id/number_picker"/>

/**
* set focus to top level window
* disposes descendant focus
* disposes softInput
* #param context - activity context
* #param enable - state of focus
* */
public static void topLevelFocus(Context context, boolean enable){
if(Activity.class.isAssignableFrom(context.getClass())){
ViewGroup tlView = (ViewGroup) ((Activity) context).getWindow().getDecorView();
if(tlView!=null){
tlView.setFocusable(enable);
tlView.setFocusableInTouchMode(enable);
tlView.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);
tlView.requestFocus();
}
}
}
* calling this:
will not block descendant focusability (numberpicker will be editable)
will hide soft input on create
before (processing input) getValue() will allow to get proper walue

This extension is nice to not forget how to do it and have readable code. It is little bit hiding implementation details, but in this case I believe it's acceptable:
fun NumberPicker.disableTextEditing(disable: Boolean) {
descendantFocusability = if (disable) FOCUS_BLOCK_DESCENDANTS else FOCUS_BEFORE_DESCENDANTS
}
