Re: [android-developers] Re: When the new activity starts, the data of previous activity is gone.
Hi Pranav, I didn't catch the point for your second problem. Do you want to pass the value of edittext in first activity to second activity, then show the strings in the edittext of second activiy. If so, you can try in the similar way as the first problem. BRs, Rui 2010/1/1 android09 > Hi Rui Wu, > > Thanks a lot. It works very good and perfectly as i want.

Re: [android-developers] tab index issue with soft keyboard
*1. add android:imeOptions="actionNext" for all the EditText in layout xml *
*2. For your 2 horizontal edittext d/e, set OnEditorActionListener for them;
*
*EditText et = (EditText) this.findViewById(...);
et.setOnEditorActionListener( new OnEditorActionListener() {*
* **public boolean onEditorAction(TextView v, int actionId,KeyEvent
event) {
switch(actionId) {
**case EditorInfo.IME_ACTION_NEXT:*
*
TextView v1 =
(TextView)v.focusSearch(View.FOCUS_RIGHT);
if (v1 != null) {
if (!v1.requestFocus(View.FOCUS_RIGHT)) {
throw new IllegalStateException("unfocucsable
view.");//shouldn't get here for your layout
}
} else {
v1 = (TextView) v.focusSearch(View.FOCUS_DOWN);
if(v1 != null) {
if(!v1.requestFocus(View.FOCUS_DOWN)) {*
*throw new
IllegalStateException("unfocucsable view..."); //should get here for your
layout
}
}
}
break;
**default:*
*
v.onEditorAction(actionId);
break;
}
return true;
}*
*} );
*
*Of course, you can have more than 2 edittexts in a line. Also you can
override the implementation as per the actual layout.*

Re: [android-developers] Re: When the new activity starts, the data of previous activity is gone.
Hi Pranav,
The way in the previous mail has an issue: if user inputs sth. in Current
activiy named Activity2, then Presses "Prev", the previous Acitivy named
Activity1 does keep the inputed contents in UI, however when user
presses "Next" here to go to Activity2, Activity2 will not keep the data
inputed by user.
Another solution: Construct a Class for your registration info i.e. Person
which implements Serializable interface.
1. For each activiy, implements the 2 buttons' logic like this:
next.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
update person according to the cotents inputed by user
Intent i = new Intent();
i.setClassName(the name of the next activity.);
i.putExtra("Person", person);... //to pass this activity's data
to next
startActivity(i);
finish();
}});
previous.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
update person according to the contents inputed by user
Intent i = new Intent();
i.setClassName(the name of the previous activity.);
i.putExtra("Person", person);... //to pass this activity's data
to next
startActivity(i);
finsh();
}});
Of course, special logic is needed for the first activity's Back button &
the last activity's Next button;
2. Add below code in OnCreate() :
Intent i = getIntent();
person = (Person)i.getSerializableExtra("Person");
if(person != null) {
update the editable ui controls according to the value of person's
member variables
} else {
person = new Person(); // this will only happen in the first activiy
}
3. For the back key handle, use the same logic as Prev button to
set onKeyListener for the activiy.

Rui

Re: [android-developers] Numeric Password in EditText

Re: [android-developers] Re: When the new activity starts, the data of previous activity is gone.
Hi Pranav,
I guess you implemented your logic like this:
Button previous = (Button) findViewById(.);
previous.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
Intent i = new Intent();
i.setClassName(the name of the previous activiy.);
startActivity(i);
}});
Try the below way:
Button next = (Button) findViewByid(.);
next.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
Intent i = new Intent();
i.setClassName(the name of the next activity.);
i.putExtra();... //to pass this activity's data to next
startActivity(i);
}});
Button previous = (Button) findViewById(.);
previous.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
finish();
}});
What you need to do is passing the current activity's data to next
Activity; When you press the Prev button, you will find Android keeps
the inputed strings in the EditText and other editable views
automatically...
Hope this can help you.
