EditText OnFocusChangeListener() doesn't hide cursor and view

I made an EditText OnFocusChangeListener that supposedly hides the cursor and another view when it's not in focus (i.e. clicking anywhere on the screen aside from the EditText will hide those items). Clicking on the EditText is the only time that will display them.
This is my OnFocusChangeListener for my EditText pageTitle:
pageTitle.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean b) {
if(b) {
pageTitle.setCursorVisible(true);
saveCancelBar.setVisibility(View.VISIBLE);
} else {
pageTitle.setCursorVisible(false);
saveCancelBar.setVisibility(View.GONE);
}
}
});
I also made an OnclickListener:
pageTitle.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
pageTitle.setCursorVisible(true);
saveCancelBar.setVisibility(View.VISIBLE);
}
});
The OnClickListener works but not the OnFocusListener. Ideally, pageTitle's cursor and saveCancelBar are initially hidden and will only appear when pageTitle is clicked.

If you check the definition of onFocusChange(View v, boolean hasFocus) you will notice that your code must change like this:
pageTitle.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean hasFocus) {
if(!hasFocus) {
pageTitle.setCursorVisible(true);
saveCancelBar.setVisibility(View.VISIBLE);
} else {
pageTitle.setCursorVisible(false);
saveCancelBar.setVisibility(View.GONE);
}
}
});
This is the code for checking the soft keyboard visibility in Android
public class MainActivity extends AppCompatActivity
{
public static String TAG = MainActivity.class.getSimpleName();
private TextView saveCancelBar;
private EditText pageTitle;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setListenerToRootView();
saveCancelBar = (TextView) findViewById(R.id.cancel_bar);
pageTitle = (EditText) findViewById(R.id.title);
pageTitle.setOnFocusChangeListener(new View.OnFocusChangeListener()
{
#Override
public void onFocusChange(View view, boolean hasFocus)
{
...
}
});
}
public void setListenerToRootView()
{
final View activityRootView = getWindow().getDecorView().findViewById(android.R.id.content);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener()
{
#Override
public void onGlobalLayout()
{
Rect r = new Rect();
activityRootView.getWindowVisibleDisplayFrame(r);
int screenHeight = activityRootView.getRootView().getHeight();
// r.bottom is the position above soft keypad or device button.
// if keypad is shown, the r.bottom is smaller than that before.
int keypadHeight = screenHeight - r.bottom;
Log.e(TAG, "keypadHeight = " + keypadHeight);
if (keypadHeight > screenHeight * 0.15) {
// 0.15 ratio is perhaps enough to determine keypad height.
Toast.makeText(getApplicationContext(), "Gotcha!!! softKeyboard open", Toast.LENGTH_SHORT).show();
} else {
// keyboard is closed
Toast.makeText(getApplicationContext(), "Gotcha!!! softKeyboard closed", Toast.LENGTH_SHORT).show();
saveCancelBar.setVisibility(View.GONE);
}
}
});
}
}

I think you forgot to add focusableInTouchMode. Add focusableInTouchMode to your editText to get focused on touching the view.
android:focusableInTouchMode="true"

Android custom dialog displays extra space

My custom dialog adds extra space after the Cancel and Save button. I have made a couple of custom dialogs in this app, but this problem appears only in this case. I've colored the view's background to blue, so I think it should be okay.

Displaying the dialog:

builder.setView(recurrencesDialogView)
.setTitle(R.string.set_recurrence)
.setPositiveButton(R.string.save, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) { }
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
#Override

}
});
final Dialog dialog = builder.create();
dialog.setCancelable(false);
dialog.show();
((AlertDialog)dialog).getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<Teaching> newRecurrences = recurrencesDialogView.saveRecurrences();
if (newRecurrences != null) {
recurrences.addAll(newRecurrences);
Collections.sort(recurrences, new Comparator<Teaching>() {
#Override
public int compare(Teaching lhs, Teaching rhs) {
if (lhs.getBegin() < rhs.getBegin())
return -1;
else
return 1;
}
});
updateListViewAdapter();
dataChangedListener.setChanged(true);
dialog.dismiss();
}
}
});
((AlertDialog)dialog).getButton(AlertDialog.BUTTON_NEUTRAL).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
I've compared the layout file with the other dialog's files, but can't figure out where the problem is.

I think the problem is with the android:layout_weight you set for your view.
Try change your:
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0.2"
android:visibility="visible"/>
To this:
<View
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.2"
android:visibility="visible"/>
I am not really sure what you trying to achieve, but think this will show you the direction (hopefully the right one).

Hiding keyboard in fragments

I am having a fragment and in that fragment there is an add button which triggers a dialog when clicked . In that dialog I am having two edittext and two buttons. On click of save button dialog is dismissed. Now problem is that when I click on save button edit text keyboard closes and another keyboard pop up.(Edit text keyboard type is number while that popup after is alphabetical).I want to close this keyboard therefore I tried configChanges and this method
public static void hideKeyboard(Context ctx) {
InputMethodManager inputManager = (InputMethodManager) ctx
.getSystemService(Context.INPUT_METHOD_SERVICE);
// check if no view has focus:
View v = ((Activity) ctx).getCurrentFocus();
if (v == null)
return;
inputManager.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
But none of this method works and I am also not having any edit text in fragment from which dialog appears.

What's the issue here??
**EDIT:**After checking for each edit text individually I found that the keyboard from first editext didn't closes itself.So I added focus change listener and when it loses focus I called hide Keyboard.
I debugged line by line and everything works perfectly, debugger also enters hide keyboard method but that code is not able to hide keyboard. Is there any other method for hiding keyboard in fragments??
Is this problem with context that is passed in hide keyboard method ??Can we get context of an alert dialog in android because when I debug it showing context of Main Activity as I am passing getActivity() as parameter .Is this the issue??

public static void hideSoftKeyboard(Activity activity) {
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
create this methos infragment and call this method where u want to hide keyboard in your fragment.

Hiding Keyboard using method doesn't work for me. I added the code directly in submit button and that worked for me. Here is what I added
InputMethodManager im = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
im.hideSoftInputFromWindow(et_name.getWindowToken(), 0);
InputMethodManager im1 = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
im1.hideSoftInputFromWindow(et_dns.getWindowToken(), 0);
Here et_dns and et_name are my edit text

how multiple selected spinner item data display on one editbox when I am click on button

when I am selected multiple spinner item that all data item display on one separated edit box. this is one part of code and xml.
public void addItemsOnSpinner(){
sp1=(Spinner) findViewById(R.id.spinner1);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.facility_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp1.setAdapter(adapter);
}
public void onItemSelected(AdapterView<?> spinner, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
switch(view.getId()){
//Spinner spinner1,spinner2,spinner3;
case R.id.spinner1:
Toast.makeText(myetms.this,"spinner1",Toast.LENGTH_LONG).show();
//break
case R.id.spinner2:
Toast.makeText(myetms.this,"spinner2",Toast.LENGTH_LONG).show();
//break;
case R.id.spinner3:
Toast.makeText(myetms.this,"spinner3",Toast.LENGTH_LONG).show();
break;
}
//sendSMS("9819861968","+location[index]");
//sc.setVisibility(view.VISIBLE); }
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub

};
public void onItemSelected(AdapterView<?> sp1,View view,int pos,long id){
//sc.setText((CharSequence) sp1.getSelectedItem());
sc.setVisibility(view.VISIBLE);

Try this:
Globally define String Variable in which you need to store your different Spinner Selected Values.
Suppose you have 3 Spinners:
Then Define like:
String Spinner1Value,Spinner2Value,Spinner3Value;
before your
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
.....
}
Now on Every Spinner setOnItemSelectedListener():
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int position,
long id) {
try
{
Spinner1Value= spinner1.getSelectedItem().toString();
}
catch(Exception e)
{
Toast.makeText(getBaseContext(), "Error::"+e.toString(), Toast.LENGTH_LONG).show();
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
and after that you can get the selected values from Spinner1Value,Spinner2Value,Spinner3Value.
Like:
edittext1.setText(Spinner1Value+Spinner2Value+Spinner3Value);
Hope this may help you!

Android transparent activity cannot make action in background activity

Hi I am working with android.I had created an app in which I had called second activity as intent and I make its background transparent.Second Activity contains a button and when click on it it shows a slidedrawer. After calling 2nd one I can view 1st activity because 2nd activity background is transparent.But How can I make an action even when the 2nd activity is also there ???
here is my code
1st activity
public class MainActivity5 extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.blah);
Button b1=(Button)findViewById(R.id.button1);
b1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intnt = new Intent(MainActivity5.this,
GestureActivity.class);
startActivity(intnt);
Toast.makeText(getApplicationContext(), "clicked", Toast.LENGTH_SHORT).show();
}
});
}
}
2nd activity
public class GestureActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main1);
Toast.makeText(getApplicationContext(), "library", Toast.LENGTH_LONG).show();
}

is it possible to make both activity can run at the same time ???

No yaar you can't run both activities at the same time .You will get a clear idea about this if you know the activity lifecycle.
Below is the link which gives clear idea about activity lifecycle
