封装了Android平台上的ProgressBar的React组件。这个组件可以用来表示应用正在加载或者有些事情正在进行中。

例子：

render: function() {
  var progressBar =
    <View style={styles.container}>
      <ProgressBar styleAttr="Inverse" />
    </View>;

  return (
    <MyLoadingComponent
      componentView={componentView}
      loadingView={progressBar}
      style={styles.loadingComponent}
    />
  );
},
