In EditText, popup a dialog when clicking on specific subset of text
Found two solutions - please see selected answer
When the user clicks in a certain region of an EditText, I want to popup a dialog. I used onClick to capture the click. This partially works: the first time the user taps the EditText, the soft keyboard pops up and the dialog doesn't. Subsequent taps bring up the keyboard and then the dialog (and the keyboard disappears).
I suspect this has something to do with the EditText gaining focus.
Here's a code snip:
public class PrefixEditText extends EditText implements TextWatcher, OnClickListener
{
public PrefixEditText (Context context)
{
super (context);
setOnClickListener (this);
}
@Override
public void onClick(View v)
{
int selStart = getSelectionStart();
if (selStart < some_particular_pos)
bring_up_dialog();
}
}
IMPORTANT: I don't want to completely disable the normal EditText behavior. I want the user to be able to make region selections (for copy & paste). I probably still want it to gain focus (so I don't break the model when people with physical keyboards use the app). And it's ok for the click to set the cursor position. Thus, solutions that override onTouch and block all onTouch actions from the EditText will not work for me.
UPDATE I've discovered a bit more. If the EditText is gaining focus, onFocusChange gets called and onClick does not. If it already has focus, onClick gets called and onFocusChange does not.
Secondly, it's possible to hide the keyboard by calling
setInputType (InputType.TYPE_NULL);
Doing so in onFocusChange works - the keyboard never shows up. Doing so in onClick (assuming the keyboard was hidden before the click) apparently is too late - the keyboard shows up and then disappears.
The next idea to try would be to hide the keyboard during onTouch. However, I'm afraid to mess with that code - seems that whatever I figure out would be very fragile with respect to future versions of EditText.
Any thoughs on this?
May be this can work
EditText e = new EditText(context);
e.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
if(hasFocus)
{
//dialogue popup
}
}
});
or u can use e.hasFocus(); and then use e.setFocusable(false); to make it unfocus
/////////////// my code
e.setInputType(InputType.TYPE_NULL);
e.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
AlertDialog.Builder sa = new Builder(ctx);
sa.create().setOnDismissListener(new OnDismissListener() {
public void onDismiss(DialogInterface dialog) {
// TODO Auto-generated method stub
e.setInputType(InputType.TYPE_CLASS_TEXT);
}
});
sa.show();
}
});
尝试通过onClick更改捕获点击到onTouch
this.editText.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
//dialogue popup
}
return false;
}
});
尝试这个，如果它可以帮助u.first第一次edittext将表现为一个正常的editttext和条件你可以根据需要显示对话框
EditText editText;
mTim_edittext.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus){
//statement
if(condition){
AlertDialog diaBox = Utils.showErrorDialogBox( "Term in Months Cannot be 0", context);
diaBox.show();
}
}
}
});
