更改一个进度条将更改所有进度条

Question

我有三个进度条，应该更新以显示以抽认卡格式显示的每个主题的进度。 每个进度条应单独进行。 我正在使用共享首选项将进度卡中的进度保存下来，然后将数据加载到处理进度条的活动中。 我只设置了第一个进度条以进行调整，但所有3个进度条的调整都与第一个相同。

我的progressbar 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"
/>

除了id以外，所有3个进度条看上去都差不多。

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);

我从抽认卡活动中将数据加载到进度栏活动中

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

我根据从抽认卡活动中加载的数据来设置进度条（我仅设置了简介进度条，因此没有理由让我的其他进度条更改与此进度同步的进度）

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

对于跳过部分代码，我深表歉意。 我也在我的Progressbars上应用了一个可绘制的

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);

Answer 1

解决方案：为每个进度栏添加一个不同的可绘制对象

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);
