只能選擇閃偏好的一個複選框checkedboxs

Question

我的應用程序啓動依賴於用戶偏好研究用三種不同的checkedbox：

1-開始應用，但不飛濺和音樂。

2-啓動應用程序只有飛濺。

3-啓動spalsh和音樂的應用程序。

與下面的代碼完美的工作。

但仍然是兩個點來實現：

FIRST只有一個複選框應進行檢查。

第二你檢查checkboxs中的任何一個後，根據自己的喜好再回去mainactivity，在這裏你可以退出該應用程序或者通過使用後退按鈕或退出按鈕我已經在我的選項菜單，問題是要麼使用後退按鈕或退出按鈕它不響應第一次點擊，我必須點擊兩次退出應用程序。

，但我不能達到它，

任何幫助，請將不勝感激。

在XML文件夾：的prefs.xml

<?xml version="1.0" encoding="utf-8" ?> 
    <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> 

    <CheckBoxPreference android:title="without splash screen" 
       android:defaultValue="true" 
       android:key="without_splash_screen" 
       android:summary="Start app without splash"/> 

    <CheckBoxPreference android:title="splash screen" 
       android:defaultValue="true" 
       android:key="splash" 
       android:summary="Start app with splash only" /> 

    <CheckBoxPreference android:title="splash screen music" 
       android:defaultValue="true" 
       android:key="splash_music" 
       android:summary="Start app with splash and music" /> 

</PreferenceScreen>

任何意見，謝謝。

UPDATE 3（整個項目）：

-1-酮選中複選框完全實現。

2-在MainActivity中使用後退按鈕或退出按鈕，不響應第一次點擊，我必須點擊兩次或三次才能退出應用程序。

Answer 1

「FIRST只有一個複選框應進行檢查。」

不知道如何使這個簡短和容易的答案，但與我一起，這工程。

創建您從活動中調用的偏好活動。

使用這樣的事情在你的onOptionSelected：

case R.id.prefs: 
     Intent p = new Intent(MainActivity.this, Prefs.class); 
     startActivity(p); 
     break; 

這是偏好設置。類

public class Prefs extends PreferenceActivity { 
CheckBoxPreference splash; 
CheckBoxPreference splash_music; 
CheckBoxPreference no_splash_music; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 

    addPreferencesFromResource(R.xml.prefs); 



    splash = (CheckBoxPreference) findPreference("splash"); 
    splash_music = (CheckBoxPreference) findPreference("splash_music"); 
    no_splash_music = (CheckBoxPreference) findPreference("without_splash_screen"); 

    splash.setOnPreferenceChangeListener(new OnPreferenceChangeListener() { 

     @Override 
     public boolean onPreferenceChange(Preference preference, 
       Object newValue) { 
      // TODO Auto-generated method stub 

      splash.setChecked(true); 
      splash_music.setChecked(false); 
      no_splash_music.setChecked(false); 

      return true; 
     } 

    }); 

    splash_music 
      .setOnPreferenceChangeListener(new OnPreferenceChangeListener() { 

       @Override 
       public boolean onPreferenceChange(Preference preference, 
         Object newValue) { 
        // TODO Auto-generated method stub 

        splash.setChecked(false); 
        splash_music.setChecked(true); 
        no_splash_music.setChecked(false); 

        return true; 
       } 

      }); 

    no_splash_music 
      .setOnPreferenceChangeListener(new OnPreferenceChangeListener() { 

       @Override 
       public boolean onPreferenceChange(Preference preference, 
         Object newValue) { 
        // TODO Auto-generated method stub 

        splash.setChecked(false); 
        splash_music.setChecked(false); 
        no_splash_music.setChecked(true); 

        return true; 
       } 

      }); 

    } 

} 

而且不要忘了將它添加到清單：

<activity 
     android:name="com.lordmarty.testforlools.Prefs" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="com.lordmarty.testforlools.PREFS" /> 

      <category android:name="android.intent.category.DEFAULT" /> 
     </intent-filter> 
    </activity> 

的的prefs.xml文件是一樣的，你貼一個。

讓我知道你是否有任何錯誤。我測試過了，它在這裏工作得很好。

「第二」

不知道爲什麼你必須點擊兩次。但這可能是由於飛濺沒有完成而引起的，只是調用了新的意圖。 試試這個在任何你從飛濺啓動mainclass：

finally{ 
      Intent intent = new Intent(Splash.this, MainActivity.class);          
      startActivity(intent); 
      finish(); 

      } 

現在，我看過了你的項目，發現它爲什麼有那麼馬車。

的主要原因是：

 if (music == true)  
    ourSong.start(); 

    Thread timer = new Thread(){ 

這裏你缺少一個括號內爲if語句，導致線程每次運行。因此，您有兩個MainActivities同時運行。

其他注意事項：對所有值使用「if」。我建議你使用「其他如果」。

我做了一個小清理。

這裏你去。享受：

Link to Splash.java

您可以通過多種方式解決過去的問題。其中一人被這樣的：

// add this below the other if else if statements in the splass.java 
else if(without_splash_screen == false && splash == false && music == false){ 
//put whatever you want to happen if none of them are checked. This is just an example. 
setContentView(R.layout.splash); 
     setContentView(R.layout.splash); 
     Thread timer = new Thread() { 
      public void run() { 
       try { 
        sleep(2000); 
       } catch (InterruptedException e) { 
        e.printStackTrace(); 
       } finally { 
        Intent intent = new Intent(Splash.this, 
          MainActivity.class); 
        startActivity(intent); 
        finish(); 


       } 
      } 
     }; 
     timer.start(); 

Answer 2

你就應該能夠將其更改爲

boolean without_splash_screen = getPrefs.getBoolean("without_splash_screen", true); 
    boolean splash = getPrefs.getBoolean("splash", true); 
    boolean splash_music = getPrefs.getBoolean("splash_music", true); 

    if (without_splash_screen) 
    { 
     ... 
    } 
    else if (splash) 
    { 
     ... 
    } 
    else if (splash_music) 
    { 
     .... 
    } 

Answer 3

我實現偏好活動，看起來像複選框，如下所示內部單選按鈕..

只能有一個選擇一次。 我做到了這一點使用2多個XML文件

一個內部繪製（check_dyn.xml）和另一內部佈局（radiochecks.xml）。

check_dyn.xml

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:state_checked="false" 
      android:state_enabled="true" 
      android:drawable="@android:drawable/checkbox_off_background" /> 
    <item android:state_checked="true" 
      android:state_enabled="true" 
      android:drawable="@android:drawable/checkbox_on_background" /> 
</selector> 

radiochecks.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 
    <RadioGroup 
     android:id="@+id/radioGroup1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" > 

     <RadioButton 
      android:id="@+id/radio0" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:button="@drawable/check_dyn" 
      android:checked="true" 
      android:text="RadioButton1" /> 

     <RadioButton 
      android:id="@+id/radio1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:button="@drawable/check_dyn" 
      android:text="RadioButton2" /> 

     <RadioButton 
      android:id="@+id/radio2" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:button="@drawable/check_dyn" 
      android:text="RadioButton3" /> 
    </RadioGroup> 

</LinearLayout> 

現在，偏好，（這裏的prefs.xml）內，加偏好，並設置其佈局屬性。即

<Preference android:layout="@layout/radiochecks" 
    /> 

注：我不喜歡這樣的做法，因爲它很難獲得單個值。
