我在保存搜索栏的进度值方面存在问题。我有两个搜索栏，有一个按钮和另一个EditText小部件。点击按钮EditText，搜索栏值将保存在共享首选项中，但点击它时只保存EditText值，而不是保存搜索栏的值。我尽我所能，但它不起作用。我的代码如下，
Profile2Activity.class
public class Profile2Activity extends Activity {
//TextViews to show details of volume and brightness
private TextView tVBrightness, tVVolume;
//SeekBars to set volume and brightness
private SeekBar sbVolume, sbBrightness;
//AudioManager object, that will get and set volume
private AudioManager audioManager;
//Variable to store brightness value
private int brightness;
//Content resolver used as a handle to the system's settings
private ContentResolver cResolver;
//Window object, that will store a reference to the current window
private Window window;
int maxVolume = 1;
EditText e2;
