我有三个进度条应该更新，以显示以flashcard格式查看的每个主题的进度。每个进度条应单独进行。我使用共享首选项来保存闪卡活动中的进度，然后将该数据加载到处理进度条的活动上。我只设置了我的第一个进度条进行调整，但所有3个进度条的调整与第一个相同。
我的进度条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个进度条看起来都非常相似，除了id。
闪存卡活动中保存的数据
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();
}
我在进度条活动中定义了进度条
progressBarIntro = (ProgressBar)myView.findViewById(R.id.introProgress);
progressBarStudy = (ProgressBar)myView.findViewById(R.id.howToStudyProgress);
progressBarProcedures = (ProgressBar)myView.findViewById(R.id.proceduresProgress);
我将我的闪卡活动中的数据加载到我的进度条活动
private void loadPreferences()
{
SharedPreferences sharedPreferences = this.getActivity().getSharedPreferences("Intro", Context.MODE_PRIVATE);
introProgressValue = sharedPreferences.getInt("Intro Progress", 0);
introViewed = sharedPreferences.getBoolean("Viewed State", false);
}
我根据flashcard活动加载的数据设置了我的进度条（我只设置了介绍进度条，所以没有理由我可以看到我的其他进度条改变它们与此同步的进度）
private void setupProgressBars(){
if(!introViewed){
progressBarIntro.setProgress(0);
}
if(introViewed){
progressBarIntro.setProgress(introProgressValue + 1);
}
progressBarIntro.setMax(4);
}

<!-- ADVIEW GOES HERE-->
</RelativeLayout>
我为跳过部分代码而道歉。我也在将一个drawable应用到我的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);
答案 0 :(得分：0)
解决方案：为每个进度条添加不同的drawable
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);
