當dialog中包含EditeText的時候，假如當前軟鍵盤是彈出的狀態(tài)巴刻，當dialog執(zhí)行dismiss()的時候該軟鍵盤并不會消失淆珊。如果需要軟鍵盤隱藏涮因，重寫dismiss()方法

@Override
public void dismiss() {
View view = getCurrentFocus();
if (view instanceof TextView) {
InputMethodManager mInputMethodManager = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
mInputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.RESULT_UNCHANGED_SHOWN);
}
super.dismiss();
}
