android - progressBar.setIndeterminateDrawable() 不起作用

Question

当我尝试更改我的 indeteminateDrawable 进度条时，它就消失了(我必须为我的进度条更改可绘制对象。我尝试了 invalidate、requestLayout 等。我不知道该如何解决。谢谢…………

这里代码:

progressBar.setIndeterminateDrawable(getResources().getDrawable(R.drawable.‌​progress_indeterminate_horizontal_didnt_like));

progressBar.setIndeterminate(true); 

是的。它在 XML 中可见。

 <ProgressBar
        android:id="@+id/progress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:indeterminate="true"
         android:indeterminateDrawable="@drawable/progress_indeterminate_horizontal_to_review" />

  private void showProgressByCategory(String category) {
        progressBar = (ProgressBar) findViewById(R.id.progress);


        switch (CATEGORY.getPosition(category)) {
        case CATEGORY.DIDNT_LIKE_POS:
            // Didnt like
            progressBar.setIndeterminateDrawable(getResources().getDrawable(
                    R.drawable.progress_indeterminate_horizontal_didnt_like));

            break;
        case CATEGORY.TO_SEE_POS:
            // To See
            progressBar.setIndeterminateDrawable(getResources().getDrawable(
                    R.drawable.progress_indeterminate_horizontal_to_see));
            break;
        case CATEGORY.SAW_AND_LIKED_POS:
            // Saw And Liked
            progressBar.setIndeterminateDrawable(getResources().getDrawable(
                    R.drawable.progress_indeterminate_horizontal_saw_liked));
            break;
        case CATEGORY.TO_REVIEW_POS:
            // To Review
            progressBar.setIndeterminateDrawable(getResources().getDrawable(
                    R.drawable.progress_indeterminate_horizontal_to_review));

            break;
        }
        progressBar.setIndeterminate(true);
    }

你必须在setIndeterminateDrawable()之前调用具有固有尺寸的drawable.setBounds()来解决
