ProgressBar e progressBarStyleHorizontal imbottitura

Question

ho una barra di avanzamento definiti grazie a questo codice:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
    <ProgressBar 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     style="?android:attr/progressBarStyleHorizontal" 
     android:indeterminate="true" 
     android:paddingTop="0dp" 
     android:paddingBottom="0dp" 
     android:id="@+id/fragment_article_progressBar" 
     android:visibility="visible" 
     /> 

     <WebView 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:id="@+id/fragment_article_content"/> 

</LinearLayout> 

Ma quando l'eseguo, un po 'di imbottitura è aggiunto sopra e sotto la ProgressBar

E' non sembra molto naturale

È lo stile normale di un ProgressBar orizzontale? Se no, come posso risolverlo?

Answer 1

provare a sostituire

<ProgressBar 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     style="?android:attr/progressBarStyleHorizontal" 
     android:indeterminate="true" 
     android:paddingTop="0dp" 
     android:paddingBottom="0dp" 
     android:id="@+id/fragment_article_progressBar" 
     android:visibility="visible" 
     /> 

Via

<ProgressBar 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     style="?android:attr/progressBarStyleHorizontal" 
     android:indeterminate="true" 
     android:layout_marginBottom="-4dp" 
     android:layout_marginTop="-4dp" 
     android:id="@+id/fragment_article_progressBar" 
     android:visibility="visible" 
     />

Prova come di seguito:

<ProgressBar 
     android:id="@+id/fragment_article_progressBar" 
     style="?android:attr/progressBarStyleHorizontal" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginTop="-6dp" 
     android:layout_marginBottom="-6dp" 
     android:indeterminate="true" 
     android:max="100" 
     android:progress="50" 
     android:visibility="visible" />
