requestFocus() method not working for edittext

I have an 2 edit texts, one of them is visible and other is not. I have set visibility "gone" for the invisible one. Now when I click input method next from edittext one, I make edittext two visible and request focus there, it gets visible but focus is not there. Interesting thing is I made visibility "invisible" instead of "gone". here is the code...
option1.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if(actionId == EditorInfo.IME_ACTION_NEXT){
option2.setVisibility(View.VISIBLE);
option2.requestFocus();
}
return false;
}
});

I am not sure it will work or not.
But your setOnEditorActionListener() is returning false, make it to return true.

Moving the focus of Edittext horizontally in list adapter android

Showing EditText in ListView adapter issue coming into focus:
Each List item has three EditText. I want to change the focus horizontally.
I am successfully able to move focus from the first to the third EditText using this code.
The issue is coming when I press softkeyboard next. I want to move the focus to the next list row, first EditText. However, when I use this code given below the focus switches to the same list, first EditText
holder.edtStock.setOnEditorActionListener(new OnEditorActionListener() {
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_NEXT) {
if(holder.edtStock.hasFocus())
holder.edtOrderStock.requestFocus();
return true;
}
return false;
}
});
holder.edtOrderStock.setOnEditorActionListener(new OnEditorActionListener() {
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_NEXT) {
if(holder.edtOrderStock.hasFocus())
holder.edtStock.requestFocus();
return true;
}
return false;
}
});
I want to achieve this:

In your EditText using android:nextFocusForward="#+id/edtNumeroInterior" and android:imeOptions="actionNext"
if you want to change to down using nextFocusDown

How do you change an EditText based on another EditText?

I have two EditTexts. Is there a way to code the program in a way that changing one EditText would change the other?
For example, if chicken is 200 calories per 100 grams, then changing the EditText of chicken to 100 will result in an auto update of 100 grams to 50 grams, without clicking anything.

You could install an OnEditorActionListener on your EditText and perform the action when the user stops typing:
myEditText.setImeOptions(EditorInfo.IME_ACTION_DONE);
myEditText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
// call some other function to test the value and
// set the result on the other EditText
return true;
}
return false;
}
});

Android: how to ignore Enter key so the focus won't change

I have an Activity with two EditText fields. So when I press enter in the first one the second one becomes focused.
However I want to disable Enter key in the first EditText sometimes (for example when I think that the user haven't made a proper input into the first EditText).
I' ve overwriten onKeyDown for the 1st EditText returning true when key event is KEYCODE_ENTER but that doesn't help.
What shall I do?

How about adding an OnFocusChangeListener? When your EditText looses focus, you can do validation and can do a requestFocus for the "right" field.

Just by adding an editorActionListener:
editText1.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE || event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
if(isValidContent(editText1.getText().toString()){
editText2.requestFocus();
return true;
} else {
....
}
}
return false;
}
});

How can I use the android landscape keyboard buttons?

I have an activity with two EditTexts. If, in landscape mode, I select the first EditText, the keyboard that is displayed has a "next" button which should allow me to type in the second EditText. Likewise, the second EditText has a "done" button, which I would like to handle for completing the activity. How can I handle the selection of these buttons?

There is fairly little documentation on how to solve this issue. I found a good solution here. Basically, you can add an IMEoption for each of the EditTexts:
For the first one:
android:imeOptions="actionNext"
For the second one:
android:imeOptions="actionDone"
To handle these in the code, try something like this:
EditText departureAddress, destinationAddress;
departureAddress = (EditText)findViewById(R.id.departure);
//Set the action of the "next" button to bring destinationAddress to focus
destinationAddress(new OnEditorActionListener(){
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_NEXT) {
destinationAddress.requestFocus();
}
return true;
}
});
destinationAddress = (EditText)findViewById(R.id.destination);
//Set the action of the "done" button to handle the map query
destinationAddress.setOnEditorActionListener(new OnEditorActionListener(){
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
//Handle map query
}
return true;
}
});
