我收到了一個ListView的問題,我想對其進行自定義。 ListView應該提供RingtonePreference的功能。大多數情況下,這種方式運行得非常好,但ListView向用戶顯示的方式並不一致。我嘗試了不同的方法,但是我的自定義ListView分成兩部分,或者對話框的按鈕超出範圍。見下圖下來..自定義ListView的奇怪行爲
這裏是我的代碼:
@Override
protected View onCreateDialogView() {
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(mContext);
SharedPreferences.Editor editor = preferences.edit();
String mThemeSettings = MyVars.THEME_KEY_DEFAULT;
// Theme-Einstellungen
if (preferences.contains(MyVars.SETTING_THEME)) {
mThemeSettings = preferences.getString(MyVars.SETTING_THEME, yVars.THEME_KEY_DEFAULT);
} else {
editor.putString(MyVars.SETTING_THEME, mThemeSettings);
editor.apply();
}
// View für Rückgabe anlegen
View view;
if (mThemeSettings.equals(MyVars.THEME_KEY_2)) {
view = View.inflate(mContext, R.layout.custom_list_preference_black, null);
} else view = View.inflate(mContext, R.layout.custom_list_preference_white, null);
mDialogTitle = getDialogTitle();
if (mDialogTitle == null) mDialogTitle = getTitle();
((TextView) view.findViewById(R.id.dialog_title)).setText(mDialogTitle);
ListView list = (ListView) view.findViewById(android.R.id.list);
ArrayAdapter<CharSequence> adapter;
if (mThemeSettings.equals(MyVars.THEME_KEY_2)) {
adapter = new ArrayAdapter<CharSequence>(
getContext(), R.layout.btn_radio_black,
getEntries());
} else {
adapter = new ArrayAdapter<CharSequence>(
getContext(), R.layout.btn_radio_white,
getEntries());
}
// Adapter setzen
list.setAdapter(adapter);
// Achtung: vorher Clickable setzen, sonst werden die Vorgaben nicht angenommen...
list.setClickable(true);
list.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
list.setItemChecked(findIndexOfValue(mPath), true);
list.setOnItemClickListener(this);
return view;
}
@Override
protected void onPrepareDialogBuilder(@NonNull Builder builder) {
super.onPrepareDialogBuilder(builder);
// Holo-Titel unsichtbar machen
builder.setTitle(null);
mMediaPlayer = new MediaPlayer();
mEntries = getEntries();
mEntryValues = getEntryValues();
builder.setPositiveButton(mContext.getString(R.string.btn_ok), this);
builder.setNegativeButton(mContext.getString(R.string.btn_cancel), this);
}
和XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="500dp"
android:orientation="vertical">
<TextView
android:id="@+id/dialog_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:textColor="@color/white"
android:textSize="22sp"/>
<View
android:layout_width="match_parent"
android:layout_height="8dp"
android:background="@color/blue_app_color"/>
<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:listSelector="@color/blue_app_color"/>
</LinearLayout>
</LinearLayout>
啊,我只是複製了錯誤的代碼: - /按鈕離開屏幕時,我ListView的匹配父。 .. – 2014-10-27 08:48:45
@MartinPfeffer用*正確的*代碼更新你的問題。 – Simas 2014-10-27 09:16:56
