我可以通过android:layout属性为偏好设置适当的布局。例如
<Preference
android:key="friction"
android:title="@string/friction"
android:layout="@layout/friction_fragment"
android:shouldDisableView="true"
android:defaultValue="30"
android:enabled="true"
android:selectable="true"
android:summary="Bite friction">
</Preference>
布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:text="@string/friction" android:textAppearance="?android:attr/textAppearanceLarge" android:layout_height="wrap_content" android:layout_gravity="center_horizontal"></TextView>
<SeekBar android:layout_height="wrap_content" android:layout_width="fill_parent" android:id="@+id/sbFriction"></SeekBar>
<TextView android:text="@string/friction_little" android:id="@+id/txtSummary" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
<Button android:text="Button" android:id="@+id/btnFriction" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>
我可以在PreferenceActivity中获取OnCreate中的视图
Preference fric = (Preference)this.findPreference("friction");
View v = fric.getView(null, null);
SeekBar sbFriction = (SeekBar)v.findViewById(R.id.sbFriction);
sbFriction.setOnSeekBarChangeListener(this);
Button btnFric = (Button) v.findViewById(R.id.btnFriction);
btnFric.setOnClickListener(m_onClick);
但是我设置的这些事件监听器不会被触发。 我如何捕获这些事件，例如 - 单击按钮。 编辑。 不，它没有发动任何异常。 这是更详细的代码
public class SettingsActivity extends PreferenceActivity implements OnPreferenceChangeListener, OnSeekBarChangeListener
{
private TextView m_txtSummary;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
ListPreference difficulty = (ListPreference)this.findPreference("difficulty");
difficulty.setSummary(difficulty.getEntry());
difficulty.setOnPreferenceChangeListener(this);
Preference fric = (Preference)this.findPreference("friction");
View v = fric.getView(null, null);
SeekBar sbFriction = (SeekBar)v.findViewById(R.id.sbFriction);
sbFriction.setOnSeekBarChangeListener(this);
Button btnFric = (Button) v.findViewById(R.id.btnFriction);
btnFric.setOnClickListener(m_onClick);
m_txtSummary = (TextView)v.findViewById(R.id.txtSummary);
fric.setSummary(fric.toString());
fric.setOnPreferenceChangeListener(this);
CheckBoxPreference music = (CheckBoxPreference)this.findPreference("music");
music.setOnPreferenceChangeListener(this);
}
private OnClickListener m_onClick = new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
v.getId();
}
};
@Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
if(newValue instanceof Boolean)
return true;
preference.setSummary(newValue.toString());
return true;
}
@Override
public void onProgressChanged(SeekBar v, int nProgress, boolean arg2) {
// TODO Auto-generated method stub
m_txtSummary.append(" " + nProgress);
m_txtSummary.invalidate();
}
@Override
public void onStartTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
}
@Override
public void onStopTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
//notifyChanged();
}
}
答案 0 :(得分：2)
我不确定您是否能够按照上述方式将自定义布局与PreferenceActivity结合使用。
我相信你应该：
通过PreferenceScreen使用addPreferencesFromResource()，并为CheckBoxPreference项目实施DialogPreference，MultiSelectListPreference和SharedPreferences等类。 （example）
或
使用自定义布局（使用Activity）创建自定义PreferenceActivity（不是setContentView()），并使用SharedPreferences手动挂钩PreferenceManager.getDefaultSharedPreferences()事件监听器（View.onClickListener()等）使用SharedPreferences.Editor。
希望这是有道理的。
答案 1 :(得分：0)
实际上我找到了另一个解决方案。您仍然可以使用Preferenceability：
只需添加一个调用自定义布局的片段并添加它的类。 但是你会在Manifest中收到警告:(你可以忽略或修复）
[res]（AndroidManifest.xml）
android:name=".SettingsActivity_CUSTOMLAYOUT1"
“YOURPACKAGE.SettingsActivity_CUSTOMLAYOUT1不公开”
它只能从您的SettingsActivity中调用，因此您可以忽略它
或
如果你想从外面调用这个Activity，只需为它创建一个自己的类，并将其命名为SettingsActivity_CUSTOMLAYOUT1.java。
CODE：
[java]（SettingsActivity.java）
public class SettingsActivity extends AppCompatPreferenceActivity {
private static Preference.OnPreferenceChangeListener sBindPreferenceSummaryToValueListener = new Preference.OnPreferenceChangeListener() {
@Override
public boolean onPreferenceChange(Preference preference, Object value) {
String stringValue = value.toString();
if (preference instanceof ListPreference) {
ListPreference listPreference = (ListPreference) preference;
int index = listPreference.findIndexOfValue(stringValue);
preference.setSummary(
index >= 0
? listPreference.getEntries()[index]
: null);
} else if (preference instanceof RingtonePreference) {
if (TextUtils.isEmpty(stringValue)) {
preference.setSummary(R.string.pref_ringtone_silent);
} else {
Ringtone ringtone = RingtoneManager.getRingtone(
preference.getContext(), Uri.parse(stringValue));
if (ringtone == null) {
preference.setSummary(null);
} else {
String name = ringtone.getTitle(preference.getContext());
preference.setSummary(name);
}
}
} else {
preference.setSummary(stringValue);
}
return true;
}
};

sBindPreferenceSummaryToValueListener.onPreferenceChange(preference,
