java-在偏好片段中显示Snackbar
作者：互联网
我想在应用程序中添加一个基本的快餐栏,但收到一个错误,我无法弄清原因.
我认为问题是getView(),可能是我必须使用getListView(),但是我处于静态上下文中,所以怎么办？
这是我的Java代码：
public class SettingsFragment extends PreferenceActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Display the fragment as the main content.
getFragmentManager().beginTransaction().replace(android.R.id.content,
new PrefsFragment()).commit();
ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#4CAF50")));
}
public static class PrefsFragment extends PreferenceFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.settings);
Preference save_database = findPreference("savedatabase");
save_database.setOnPreferenceClickListener( new Preference.OnPreferenceClickListener()
{
public boolean onPreferenceClick( Preference pref )
{
Data.bdd.Save_database(getActivity(),getView());
return true;
}
} );
final CheckBoxPreference checkboxPref = (CheckBoxPreference) getPreferenceManager().findPreference("checkbox_always_on");
checkboxPref.
setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
public boolean onPreferenceChange(Preference preference, Object newValue) {
if (newValue.toString().equals("true")) {
Screen.screen_on(getActivity());
Snackbar.make(getListView(),"Auto-extinction de l'écran désactivé",Snackbar.LENGTH_SHORT);
} else {
Screen.screen_off(getActivity());
Snackbar.make(getView(),"Auto-extinction de l'écran activé",Snackbar.LENGTH_SHORT);
}
return true;
}
});
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = super.onCreateView(inflater, container, savedInstanceState);
view.setBackgroundColor(getResources().getColor(R.color.green_800));
return view;
}
}
GradGrad相关性：
compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.android.support:support-v13:23.0.0'
compile 'com.android.support:support-v4:23.0.0'
compile 'com.android.support:design:23.0.0'
compile 'com.android.support:recyclerview-v7:23.0.0'
我有我不明白的错误

解决方法:
因此,在@YasinKaçmaz的帮助下,我找到了解决问题的答案.这是我的代码
public class SettingsFragment extends AppCompatActivity {
static CoordinatorLayout coordinatorLayout;
Activity thisActivity=this;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SnackbarShow.showSnackbar(thisActivity);
// Display the fragment as the main content.
getFragmentManager().beginTransaction().replace(android.R.id.content,
new PrefsFragment()).commit();
ActionBar bar = getSupportActionBar();
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#4CAF50")));
}
public static class PrefsFragment extends PreferenceFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.settings);
Preference save_database = findPreference("savedatabase");
save_database.setOnPreferenceClickListener( new Preference.OnPreferenceClickListener()
{
public boolean onPreferenceClick( Preference pref )
{
Data.bdd.Save_database(getActivity(),getView());
return true;
}
} );
final CheckBoxPreference checkboxPref = (CheckBoxPreference) getPreferenceManager().findPreference("checkbox_always_on");
checkboxPref.
setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
public boolean onPreferenceChange(Preference preference, Object newValue) {
if (newValue.toString().equals("true")) {
Screen.screen_on(getActivity());
showSnackbar(getView());
} else {
Screen.screen_off(getActivity());
showSnackbar(getView());
}
return true;
}
});
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = super.onCreateView(inflater, container, savedInstanceState);
view.setBackgroundColor(getResources().getColor(R.color.green_800));
return view;
}
public static void showSnackbar(View view) {
Snackbar snackbar = Snackbar
.make(view, "There is one text", Snackbar.LENGTH_LONG)
.setAction("Action Text", new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.v("snackbar","yoo clicked action");
}
});
// Changing message text color
snackbar.setActionTextColor(Color.RED);
// Changing action button text color
View sbView = snackbar.getView();
TextView textView = (TextView) sbView.findViewById(android.support.design.R.id.snackbar_text);
textView.setTextColor(Color.YELLOW);
snackbar.show();
}
}
