補充：

如果要在ActionBar上顯示一個EditText,可如下：

private View mCustomView;

bar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM, ActionBar.DISPLAY_SHOW_CUSTOM);

mCustomView = getLayoutInflater().inflate(R.layout.lay, null);      
bar.setCustomView(mCustomView, new ActionBar.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

<?xml version="1.0" encoding="utf-8"?>
<EditText
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:text="dfghjkl"
    android:layout_width="450dip"
 android:layout_height="wrap_content"
    />
