java - Focus changes to listview once i clear the Edittext -
i'm using broadcast receiver show dialog.so flow of code like:
step1 getting requestcode value
step2 based on requestcode broadcast receiver goes if or else if or else part
step3 if value entered using scanner edittext(i.e scan) doesn't matches shows toast "item not available".
step 4 once "item not available" toast comes focus changes listview problem.
step5 again if pass value scan edittext listview click automatically.
so question "how remove focus listview" , set edittext(i.e scan).
for reference i'm attaching snap code snippet , layout.xml.please have , drop suggestions why focus going listview.

add textwatcher edit text , check when text not blank , not equal expected text switch focus.
/* set text watcher listener */
youredittext.addtextchangedlistener(passwordwatcher); and check text once user enter text
private final textwatcher passwordwatcher = new textwatcher() { public void beforetextchanged(charsequence s, int start, int count, int after) { } public void ontextchanged(charsequence s, int start, int before, int count) { } public void aftertextchanged(editable s) { if (s.length() != 0 && passwordedittext.gettext().equals("your expected text")) { // show toast , change focus } } }
