After long time looking into TextView class I found a way to prevent keyboard to appears. The trick is hide it right after it appears, so I searched a method that is called after keyboard appear and hide it.
Implemented EditText class
public class NoImeEditText extends EditText {
public NoImeEditText(Context context, AttributeSet attrs) {
super(context, attrs);
}
/**
* This method is called before keyboard appears when text is selected.
* So just hide the keyboard
* @return
*/
@Override
public boolean onCheckIsTextEditor() {
hideKeyboard();
return super.onCheckIsTextEditor();
}
/**
* This methdod is called when text selection is changed, so hide keyboard to prevent it to appear
* @param selStart
* @param selEnd
*/
@Override
protected void onSelectionChanged(int selStart, int selEnd) {
super.onSelectionChanged(selStart, selEnd);
hideKeyboard();
}
private void hideKeyboard(){
InputMethodManager imm = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getWindowToken(), 0);
}
}
and style
<com.my.app.CustomViews.NoImeEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:editable="false"
android:background="@null"
android:textSize="@dimen/cell_text" />
