在ViewPager中获取图像文件的名称并在TextView中显示它

Question

我在ViewPager中有几张图片可供用户滑动，我需要在TextView中显示图片的名称。我只是靠java，然后想像代码将是这样的。

private void displayName (String name) {
    /*
    This is the code to get the name of the image that appears in the ViewPager
     */
    ViewPager swipeImages = (ViewPager) findViewById(R.id.myImageSwipe);
    String backgroundImageName = String.valueOf(swipeImages.getTag());

    /*
    This is the textView where I need the name of the image file to display
     */
    TextView imageNameTextView = (TextView) findViewById(R.id.nameImage);
    imageNameTextView.setText(name);

    displayName(backgroundImageName);
}

Answer 1

您是否将图像文件名设置为图像视图？如果是这样，您可以为文本视图设置相同的名称。

   imageNameTextView.setText(backgroundImageName);
