我可以将 set-listener 行分成更小的部分吗?
这是我的代码:
protected void onCreate(Bundle savedInstanceState) {
Preference button = (Preference)getPreferenceManager().findPreference("exitlink");
button.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
@Override
public boolean onPreferenceClick(Preference arg0) {
finish();
return true;
}
});
我希望它看起来像:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Preference button = (Preference)getPreferenceManager().findPreference("exitlink");
if(button != null) {
button.setOnPreferenceClickListener(onPreferenceClick);
}
}
public boolean onPreferenceClick(Preference arg0) {
finish();
return true;
}
