TabWidget의 구분선 적용

mTabHost.getTabWidget().setDividerDrawable(R.drawable.divider_vertical_dark);

소프트 키보드가 열린상태에서 BACK KEY 제어

public class CustomEditText extends EditText {

public CustomEditText(Context a_context) {
super(a_context);

}

public CustomEditText(Context a_context, AttributeSet a_attributeSet) {
super(a_context, a_attributeSet);
}

public boolean onKeyPreIme(int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
return true; // 사용자가 override한 함수 사용
}
}
return super.onKeyPreIme(keyCode, event); // 시스템 default 함수 사용

}
}

ListView UI 관련 팁

[리스트 라인 관련]
android:divider="#292929"

android:divider="@drawable/list_column_line"

android:dividerHeight="1px"

[리스트 쉐도우 영역 없애기]

android:fadingEdge="none"

[리스트 스크롤 없애기]

android:scrollbars="@null"

키보드 보이기, 숨기기

보이기
EditText editText = (EditText) findViewById(R.id.myEdit);
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);

숨기기
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.hideSoftInputFromWindow(editText.getWindowToken(), 0);

스크롤 버튼

setFastScrollEnabled(true) 로 설정하면 된다.
