In my android app I have the following code in the OnCreate function:
txtUsername.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View arg0, int arg1, KeyEvent arg2) {
// TODO Auto-generated method stub
String Username = txtUsername.getText().toString();
if (arg1 == KeyEvent.KEYCODE_ENTER) {
DontShowDialog = false;
if ((Username.toLowerCase().endsWith("blabla.com") == false && Username.toLowerCase().endsWith("blabla-bla.nl") == false) || validateEmail(Username) == false) {
final Dialog dialog = new Dialog(arg0.getContext());
dialog.setContentView(R.layout.startdialog);
dialog.setTitle("Warning 1");
Button btOk = (Button) dialog.findViewById(R.id.btOk);
btOk.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
DontShowDialog = true;
dialog.dismiss();
return;
}
});
if (DontShowDialog == false) {
dialog.show();
}
return false;
}
}
txtUsername.clearFocus();
txtPassword.setNextFocusDownId(txtPassword.getId());
return false;
}
});
When the user hits the NEXT button and the username is not right, a dialog is shown which can be canceled by the OK button.
But.... after hitting the OK button, the dialog is shown again... I don't want that.
Why is that happening?

By returning false in your onKey() event, you're telling Android that the KeyEvent was not consumed - so my guess is that changing the return statement to true might fix the problem, because Android would know the event was consumed, and it would not re-enter the onKey() method. If you could try that out and share the results that would be great!
Solved it.
moved the line
DontShowDialog = true;
from the OnClick part
Changed the if-then below the onClick to:
if (DontShowDialog == false) {
dialog.show();
DontShowDialog = true;
return false;
}

I have this dialog, with just a textView and no buttons. It displays some info and I need to change info on key press left and right. Unfortunately the dialog closes on any key.
This code in MainActivity invokes the dialog (redundant code omitted)
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (event.getKeyCode() == KeyEvent.KEYCODE_MENU) {
if (event.getAction() == KeyEvent.ACTION_UP) {
InfoDialog infoDialog = new InfoDialog();
infoDialog.showDialog(this,currentDateAndTime,chn);
return true;
}
}
return super.dispatchKeyEvent(event);
}
and this is the dialog code
public class InfoDialog {
private int counter = 0;
private Dialog dialog;
public void showDialog(final Activity activity, final String DateTime, final ChannelList.Channel chn){
dialog = new Dialog(activity);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(false);
dialog.setContentView(R.layout.info_dialog);
counter = 0;
setDialogText(chn,DateTime,counter);
dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
#Override
public boolean onKey(DialogInterface dialogInterface, int i, KeyEvent keyEvent) {
if (keyEvent.getKeyCode() == KeyEvent.KEYCODE_DPAD_LEFT) {
if (keyEvent.getAction() == KeyEvent.ACTION_UP) {
if (counter>0) counter--;
setDialogText(chn,DateTime,counter);
return true;
}
}
if (keyEvent.getKeyCode() == KeyEvent.KEYCODE_DPAD_RIGHT) {
if (keyEvent.getAction() == KeyEvent.ACTION_UP) {
if (counter<chn.infoText.size()-1) counter++;
setDialogText(chn,DateTime,counter);
return true;
}
}
dialog.dismiss();
return false;
}
});
dialog.show();
}
}
when I press any button, the dialog closes, even if the onKey has been invoked.
Did I miss something? how do I handle keypresses for my dialog only? (other dialogs may use same keys for different operation)
well, inside InfoDialog you are setting DialogInterface.OnKeyListener and on the bottom of onKey method you are calling dialog.dismiss(), try to remove this line... (and also return true for any case)
I have Two EditTexts. I want On First EditTexts click clear the second and on second edittext click clear the first one. So I have tried OnClickListener and OnTouchListener. But it is not working properly.
et_email.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (!(et_email.getText().toString().equalsIgnoreCase("") && et_mobile.getText().toString().equalsIgnoreCase(""))) {
if (MotionEvent.ACTION_UP == event.getAction()) {
et_mobile.setText("");
et_mobile.setFocusableInTouchMode(true);
et_mobile.setFocusable(true);
et_mobile.requestFocus();
}
return true; // return is important...
} else
return false;
}
});
et_mobile.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (!(et_email.getText().toString().equalsIgnoreCase("") && et_mobile.getText().toString().equalsIgnoreCase(""))) {
if (MotionEvent.ACTION_UP == event.getAction()) {
et_email.setText("");
et_mobile.setFocusableInTouchMode(true);
et_mobile.setFocusable(true);
et_mobile.requestFocus();
}
return true; // return is important...
}
else
return false;
}
});
But the problem is Focus is not setting on first touch and while clicking and unable to clear EditText.
First add this to your Edittext layouts:
android:focusableInTouchMode="false"
Without this line, the EditText will react to touch-mode, and only listen to your onClick() the second time you click your EditText bar.
This will disable touch-mode for EditText, and fire onClick() in first time
focusableInTouchMode
Note: boolean that controls whether a view can take focus while in touch mode. If this is true for a view, that view can gain focus when clicked on, and can keep focus if another view is clicked on that doesn't have this attribute set to true.
than do as follows:
EditText1
EditText et_email = (EditText) findViewById(R.id.yourEditText1);
et_email.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do this
et_mobile.setText("");
//or this
et_mobile.getText().clear();
}
});
EditText2
EditText et_mobile = (EditText) findViewById(R.id.yourEditText2);
et_mobile.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do this
et_email.setText("");
//or this
et_email.getText().clear();
}
});
This should help u out.
you are clearing the first one one touching the first one, change your variable names in first listener like this
if (!(et_email.getText().toString().equalsIgnoreCase("") && et_mobile.getText().toString().equalsIgnoreCase(""))) {
if (MotionEvent.ACTION_UP == event.getAction()) {
et_mobile.setText("");
et_email.setFocusableInTouchMode(true);
et_email.setFocusable(true);
et_email.requestFocus();
}
return true; // return is important...
} else
I hope this code helps you (it works for me)
edit1 = (EditText) findViewById(R.id.edit1);
edit2 = (EditText) findViewById(R.id.edit2);
edit1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
edit2.setText("");
}
});
edit2.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
edit1.setText("");
}
});
I'm showing up a Dialog on app-start, where you have to select a config. Since it is essential to select one config, I want to "disable" the back-button via a empty onBackPressed().
I got the following code in a DialogFragment:
public class ChangeConfigDialogFragment extends DialogFragment {
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the Builder class for convenient dialog construction
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.dialog_config_change)
.setItems(R.array.config_array,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
// The 'which' argument contains the index
// position
// of the selected item
if (which == 0){
Initiation.BAUDRATE = 500;
Toast.makeText(getActivity(), "Baudrate at " + Initiation.BAUDRATE, Toast.LENGTH_LONG).show();
if (Initiation.getADK() == null){
Initiation.initiateCAN();
}
} else if (which == 1) {
Initiation.BAUDRATE = 600;
Toast.makeText(getActivity(), "Baudrate at " + Initiation.BAUDRATE, Toast.LENGTH_LONG).show();
if (Initiation.getADK() == null){
Initiation.initiateCAN();
}
} else if (which == 2) {
Initiation.BAUDRATE = 700;
Toast.makeText(getActivity(), "Baudrate at " + Initiation.BAUDRATE, Toast.LENGTH_LONG).show();
if (Initiation.getADK() == null){
Initiation.initiateCAN();
}
}
}
});
// Create the AlertDialog object and return it
return builder.create();
}
public void onBackPressed(){
Log.d(getTag(), "are you there?");
}
}
The problem is, that the onBackPressed() is never been called. Even the log message does not appear.
I tried to clean the project, but no success. Also tried to use a onKeyDown-method from some other topics here on SO. Does anyone has a clue how to solve this?
EDIT:
It works now. .setCancelable(false); worked, but I was to stupid to add it to the Dialog from which the Fragment was called. (instead added it to the builder
Thanks for all your help and time.
From your question it seems that while your dialog is open you need not to close dialog untill user can select any 1 open from dialog if i am not wrong then,so for this you need not to disable back key but you have to set this two properties for dialog.
dialog.setCancelable(false);
dialog.setCanceledOnTouchOutside(false);
OR
If you want to disable back key then use the below code,
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
//preventing default implementation previous to android.os.Build.VERSION_CODES.ECLAIR
return true;
}
return super.onKeyDown(keyCode, event); }
OnbackkeyPressed Requires Api Level 5 Or higher.
#Override
public void onBackPressed() {
}
Use builder.setCancelable(false)
http://developer.android.com/reference/android/app/AlertDialog.Builder.html#setCancelable(boolean)
I did not try this, but it might work if you set the OnKeyListeneron the builder like this:
builder.setOnKeyListener(new DialogInterface.OnKeyListener() {
#Override
public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
return false;
}
}
});
Try
public boolean onKeyDown(int keyCode, KeyEvent event) {
// Handle the back button
if (keyCode == KeyEvent.KEYCODE_BACK) {
return false;
}
return super.onKeyDown(keyCode, event);
}
or
dialog.setCancelable(false);
I generate multiple EditText in a for-loop and want to update a "score" when focus is lost from one of the EditTexts. I also wish to check that the input is valid and if not, empty the EditText and set focus back to it.
The following code adds EditTexts and a onFocusChangeListener.
The problem is that when a score is not valid (updateScore(id) returns false), I want to empty the EditText and set the focus back to this view.
The problem in my code is that if I enter a value in EditText A that are not valid, and then click in EditText B. Both A and B have focus... I only want A to have focus...
How can I set the focus back to the previous EditText and be ready for new inputs to this view?
for (int player = 0; player < numPlayers; player++)
{
EditText valueET = new EditText(this);
valueET.setOnClickListener(new OnClickListener() {
#Override public void onClick(View v) {
Log.v("Focus", "Lagrer unna den som har blitt klikket, " + String.valueOf(v.getId()));
etHasFocus = (EditText) v;
}
});
valueET.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus)
{
if(!updateScore(v.getId()))
{
if (etHasFocus != null && v.getId() != etHasFocus.getId())
etHasFocus.clearFocus();
v.requestFocus();
}
});
valueET.setId(200+player*100+row);
valueET.setInputType(InputType.TYPE_CLASS_NUMBER);
valueET.setTextColor(Color.BLACK);
valueET.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
tr.addView(valueET);
}
tl.addView(tr, new TableLayout.LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
The code for updateScore(id) is (simplified):
boolean updateScore(int id)
{
EditText t = (EditText) findViewById(id);
String text = t.getText().toString();
if( !text.equals(""))
{
int score = Integer.parseInt(text);
}
if(score != 9)
return false;
TextView total = (TextView) findViewById(ID_toal);
t2.setText(String.valueOf(score));
return true;
}
Code is updated, problem now is that onClick never is called... (So etHasFocus = null)
You can try keeping a track of which EditText has been clicked. For this, create a EditText variable:
EditText etHasFocus;
In addition to adding OnFocusChangeListener, add an OnClickListener as well:
valueET.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
etHasFocus = (EditText) v;
}
});
Now, inside your OnFocusChangeListener, make the following changes:
valueET.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus) {
if(!updateScore(v.getId())) {
// Clear focus from another EditText
if (etHasFocus != null && v.getId() != etHasFocus.getId()) {
etHasFocus.clearFocus();
}
v.requestFocus();
}
}
}
});
Edit:
You are right. the onClick(View) method is called on second click. I can suggest you an alternate approach. I have tried it and its working fine:
Create a EditText variable:
EditText etCurrent;
Set an OnTouchlistener on each EditText:
valueET.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (etCurrent != null) {
if (etCurrent.getId() != v.getId()) {
if (!check(etCurrent.getId())) {
etCurrent.setSelection(0,
etCurrent.getText().toString().length());
return true;
} else {
etCurrent = (EditText) v;
}
}
} else {
etCurrent = (EditText) v;
}
}
return false;
}
});
Remove OnClickListener, onFocusChangeListener and etHasFocus.
You don't need to initialize etCurrent as if (etCurrent != null) { } else { } takes care of that.
I am writing an application to animate popup window. It was working great with my code.
I want to close the popup window(i.e to slide-down it), when back button is pressed on device.
But I couldn't listen any one key from device. I used setOnKeyListener of that popup window, I didn't even get log from it.
My Code is given below:
popup_layout = layoutInflater.inflate(R.layout.popup_addchannel, null);
popupWindow = new PopupWindow(popup_layout, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
subscribeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Log.d(TAG,
// "Button is clicked for animation.... Visibility is"
// + subscribeButton.getVisibility());
openMenu(view);
}
});
popup_layout.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
Log.d(TAG, "on key button click called.........");
return false;
}
});
public void openMenu(View view) {
if (!flag) {
popupWindow.setAnimationStyle(R.style.PopupWindowAnimation);
popupWindow.showAtLocation(view.findViewById(R.id.button1),
Gravity.CENTER, 0, 0);
popupWindow.setFocusable(true);
popupWindow.update();
flag = true;
} else {
popupWindow.dismiss();
popupWindow.setFocusable(false);
flag = false;
}
}
What is the problem behind this?
Shall i achieve my requirement?
Please, Guide me.
Thank you in Advance!
try this....
final PopupWindow popupWindow = new PopupWindow(popupView,
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT,true);
...
popupWindow.getContentView().setFocusableInTouchMode(true);
popupMenu.getContentView().setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_MENU &&
event.getRepeatCount() == 0 &&
event.getAction() == KeyEvent.ACTION_DOWN) {
// ... payload action here. e.g. popupMenu.dismiss();
return true;
}
return false;
}
});
The dialog has a property of cancelling the dialog on back press.
dialog.setCancelable(true);
EDIT: Check Qberticus answer on this link: Android popup window dismissal
and you can also see: Issue dismissing popup window
Yes you can use this
dialog_obj.setCancelable(true);
You should override the onKeyPressed() method of your activity as below.
#Override
public void onBackPressed() {
super.onBackPressed();
//your code to close the popup window.
popupWindow.setAnimationStyle(R.style.PopupWindowAnimation);
popupWindow.showAtLocation(view.findViewById(R.id.button1),
Gravity.CENTER, 0, 0);
opupWindow.setFocusable(true);
popupWindow.update();
flag = true;
}
popupWindow.getContentView().setOnClickListener(new OnClickListener()) {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
popupWindow.dismiss();
}
});
Try this.
You can't listen a key press in popup window, but when you listen to system back key, you can override dismiss() method to intercept it.
