android - How to block keyboard when focusing on EditText -
in android application, have use custom number-pad placed in view next edittexts input numbers, need:
- edittext should have focus when user tap them have cursor position insert number when user hits key.
- soft keyboard should not appear when edit text focused (but cannot hide keyboard setting android:windowsoftinputmode="statehidden" because there search box in screen still need use soft keyboard)
i have searched , found many articles hiding keyboard programmingly when being shown, or set input type/focusable....to not show keyboard....but not meet need.
anybody have solution case please me.
this 1 took inspiration csipsimple project , implemented own
here code same create custom numberpad here mine layout dialpad buttons 1 9 , * #

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <com.novanet.custom.dialeredittext android:id="@+id/edtdialer" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="70" /> <com.novanet.custom.dialpadnovanet android:id="@+id/dial_pad" android:layout_width="match_parent" android:layout_height="0dp" android:layout_gravity="center_vertical" android:layout_weight="65" android:paddingbottom="10dip" android:paddingleft="5dip" android:paddingright="5dip" /> </linearlayout> now in activity u can this
edttext=(dialeredittext)findviewbyid(r.id.edtdialer); dialpad=(dialpadnovanet)findviewbyid(r.id.dial_pad); dialpad.setondialkeylistener(new ondialkeylistener() { @override public void ontrigger(int keycode, int dialtone) { log.v(tag,"key "+keycode); keyevent event=new keyevent(keyevent.action_down, keycode); edttext.onkeydown(keycode, event); } });
