I am trying to use an alert dialog to prompt for a username and a password in android. I have found this code here:
if (token.equals("Not Found"))
{
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.userpasslayout, null);
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Please Login to Fogbugz");
alert.setMessage("Enter your email and password");
// Set an EditText view to get user input
alert.setView(textEntryView);
AlertDialog loginPrompt = alert.create();
final EditText input1 = (EditText) loginPrompt.findViewById(R.id.username);
final EditText input2 = (EditText) loginPrompt.findViewById(R.id.password);
alert.setPositiveButton("Login", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
input1.getText().toString(); **THIS CRASHES THE APPLICATION**
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
alert.show();
}
EDIT: I was able to set up the proper layout, but receive an error when I try to access the text field. What is the problem here?
I found another set of examples for customizing an AlertDialog from a guy named Mossila. I think they're better than Google's examples. To quickly see Google's API demos, you must import their demo jar(s) into your project, which you probably don't want.
But Mossila's example code is fully self-contained. It can be directly cut-and-pasted into your project. It just works! Then you only need to tweak it to your needs. See here
Check this code in alert box have edit textview when click OK it displays on screen using toast.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final AlertDialog.Builder alert = new AlertDialog.Builder(this);
final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText().toString().trim();
Toast.makeText(getApplicationContext(), value,
Toast.LENGTH_SHORT).show();
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
});
alert.show();
}
/* Didn't test it but this should work "out of the box" */
AlertDialog.Builder builder = new AlertDialog.Builder(this);
//you should edit this to fit your needs
builder.setTitle("Double Edit Text");
final EditText one = new EditText(this);
from.setHint("one");//optional
final EditText two = new EditText(this);
to.setHint("two");//optional
//in my example i use TYPE_CLASS_NUMBER for input only numbers
from.setInputType(InputType.TYPE_CLASS_NUMBER);
to.setInputType(InputType.TYPE_CLASS_NUMBER);
LinearLayout lay = new LinearLayout(this);
lay.setOrientation(LinearLayout.VERTICAL);
lay.addView(one);
lay.addView(two);
builder.setView(lay);
// Set up the buttons
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//get the two inputs
int i = Integer.parseInt(one.getText().toString());
int j = Integer.parseInt(two.getText().toString());
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
});
builder.show();
Have a look at the AlertDialog docs. As it states, to add a custom view to your alert dialog you need to find the frameLayout and add your view to that like so:
FrameLayout fl = (FrameLayout) findViewById(android.R.id.custom);
fl.addView(myView, new LayoutParams(MATCH_PARENT, WRAP_CONTENT));
Most likely you are going to want to create a layout xml file for your view, and inflate it:
LayoutInflater inflater = getLayoutInflater();
View twoEdits = inflater.inflate(R.layout.my_layout, f1, false);
Check the following code. It shows 2 edit text fields programmatically without any layout xml. Change 'this' to 'getActivity()' if you use it in a fragment.
The tricky thing is we have to set the second text field's input type after creating alert dialog, otherwise, the second text field shows texts instead of dots.
public void showInput() {
OnFocusChangeListener onFocusChangeListener = new OnFocusChangeListener() {
@Override
public void onFocusChange(final View v, boolean hasFocus) {
if (hasFocus) {
// Must use message queue to show keyboard
v.post(new Runnable() {
@Override
public void run() {
InputMethodManager inputMethodManager= (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.showSoftInput(v, 0);
}
});
}
}
};
final EditText editTextName = new EditText(this);
editTextName.setHint("Name");
editTextName.setFocusable(true);
editTextName.setClickable(true);
editTextName.setFocusableInTouchMode(true);
editTextName.setSelectAllOnFocus(true);
editTextName.setSingleLine(true);
editTextName.setImeOptions(EditorInfo.IME_ACTION_NEXT);
editTextName.setOnFocusChangeListener(onFocusChangeListener);
final EditText editTextPassword = new EditText(this);
editTextPassword.setHint("Password");
editTextPassword.setFocusable(true);
editTextPassword.setClickable(true);
editTextPassword.setFocusableInTouchMode(true);
editTextPassword.setSelectAllOnFocus(true);
editTextPassword.setSingleLine(true);
editTextPassword.setImeOptions(EditorInfo.IME_ACTION_DONE);
editTextPassword.setOnFocusChangeListener(onFocusChangeListener);
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.addView(editTextName);
linearLayout.addView(editTextPassword);
DialogInterface.OnClickListener alertDialogClickListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which){
case DialogInterface.BUTTON_POSITIVE:
// Done button clicked
break;
case DialogInterface.BUTTON_NEGATIVE:
// Cancel button clicked
break;
}
}
};
final AlertDialog alertDialog = (new AlertDialog.Builder(this)).setMessage("Please enter name and password")
.setView(linearLayout)
.setPositiveButton("Done", alertDialogClickListener)
.setNegativeButton("Cancel", alertDialogClickListener)
.create();
editTextName.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
editTextPassword.requestFocus(); // Press Return to focus next one
return false;
}
});
editTextPassword.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
// Press Return to invoke positive button on alertDialog.
alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).performClick();
return false;
}
});
// Must set password mode after creating alert dialog.
editTextPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
editTextPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());
alertDialog.show();
}
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.text_entry, null);
//text_entry is an Layout XML file containing two text field to display in alert dialog
final EditText input1 = (EditText) textEntryView.findViewById(R.id.EditText1);
final EditText input2 = (EditText) textEntryView.findViewById(R.id.EditText2);
input1.setText("DefaultValue", TextView.BufferType.EDITABLE);
input2.setText("DefaultValue", TextView.BufferType.EDITABLE);
final AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setIcon(R.drawable.icon)
.setTitle("Enter the Text:")
.setView(textEntryView)
.setPositiveButton("Save",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
Log.i("AlertDialog","TextEntry 1 Entered "+input1.getText().toString());
Log.i("AlertDialog","TextEntry 2 Entered "+input2.getText().toString());
/* User clicked OK so do some stuff */
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton) {
}
});
alert.show();
Use these lines in the code, because the textEntryView is the parent of username edittext and password edittext.
final EditText input1 = (EditText) textEntryView .findViewById(R.id.username);
final EditText input2 = (EditText) textEntryView .findViewById(R.id.password);
