更改一個進度條更改所有進度條

我有三個進度條，應更新以顯示以閃卡格式查看的每個主題的進度。每個進度條應該分別進行。我使用共享首選項來保存flashcard活動中的進度，然後將數據加載到處理進度條的活動中。我只設置了我的第一個進度條來調整，但所有3個進度條的調整與第一個相同。更改一個進度條更改所有進度條

我的進度XML

<ProgressBar 
    style="?android:attr/progressBarStyleHorizontal" 
    android:id="@+id/introProgress" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:max="4" 
    android:progress="0" 
    android:indeterminate="false" 
    android:layout_gravity="center" 
    android:padding="5dp" 
/> 

<ProgressBar 
style="?android:attr/progressBarStyleHorizontal" 
    android:id="@+id/howToStudyProgress" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:max="100" 
    android:progress="0" 
    android:indeterminate="false" 
    android:layout_gravity="center" 
    android:padding="5dp" 
/> 

<ProgressBar 
    style="?android:attr/progressBarStyleHorizontal" 
    android:id="@+id/proceduresProgress" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:max="100" 
    android:progress="0" 
    android:indeterminate="false" 
    android:layout_gravity="center" 
    android:padding="5dp" 
/>

所有3個progressbars看起來很相像除了ID。

保存在閃存卡的活動數據

private void savePosition(){ 
    SharedPreferences sharedPrefs = this.getActivity().getSharedPreferences("Intro", Context.MODE_PRIVATE); 
    SharedPreferences.Editor editor = sharedPrefs.edit(); 
    editor.putInt("Intro Progress", progress); 
    editor.putInt("Intro Position", position); 
    editor.putBoolean("Viewed State", viewed); 
    editor.commit(); 
}

我定義我的進度活動我progressbars

progressBarIntro = (ProgressBar)myView.findViewById(R.id.introProgress); 
progressBarStudy = (ProgressBar)myView.findViewById(R.id.howToStudyProgress); 
progressBarProcedures = (ProgressBar)myView.findViewById(R.id.proceduresProgress);

我從我的燒錄卡的活動載入我的數據，我的進度活動

private void loadPreferences() 
{ 
    SharedPreferences sharedPreferences = this.getActivity().getSharedPreferences("Intro", Context.MODE_PRIVATE); 
    introProgressValue = sharedPreferences.getInt("Intro Progress", 0); 
    introViewed = sharedPreferences.getBoolean("Viewed State", false); 
}

我根據從flashcard活動加載的數據設置我的進度條兩者均（我只有建立在介紹進度條，所以沒有理由，我可以看到我的其他progressbars正在改變他們的進步同步與此一）

private void setupProgressBars(){ 
if(!introViewed){ 
    progressBarIntro.setProgress(0); 
} 
if(introViewed){ 
    progressBarIntro.setProgress(introProgressValue + 1); 
} 
progressBarIntro.setMax(4); 
}

完全.xml文件顯示progressbars

我很抱歉跳過我的部分代碼。我也想申請一個可抽拉我Progressbars

Resources res = getResources(); 
Drawable drawable = res.getDrawable(R.drawable.progress); 

progressBarIntro = (ProgressBar)myView.findViewById(R.id.introProgress); 
progressBarIntro.setProgressDrawable(drawable); 

temp = (ProgressBar)myView.findViewById(R.id.temp); 
temp.setProgressDrawable(drawable);

發生了什麼變化？另外發布剩下的'ProgressBar's xmls。 – Onik

所有3個進度條都在同一個.xml文件中，並且它們是從原始文件複製而來的，但它們始終無法粘貼。即使我沒有編寫任何代碼來改變它們，所有三個進度條都在同步progressBarIntro中改變進度。 – th3ramr0d

由於'layout_gravity =「center」'屬性，它們不會相互重疊嗎？ – Onik

解決辦法：添加不同繪製的每個進度

Resources res = getResources(); 
Drawable drawableIntro = res.getDrawable(R.drawable.progress); 
Drawable drawableTemp = res.getDrawable(R.drawable.progress); 

progressBarIntro = (ProgressBar)myView.findViewById(R.id.introProgress); 
progressBarIntro.setProgressDrawable(drawableIntro); 

temp = (ProgressBar)myView.findViewById(R.id.temp); 
temp.setProgressDrawable(drawableTemp);
