Question

我有窗口默认操作栏，其中想要添加高度和宽度为30x30的Imageview。我可以这样做，我正在尝试此代码，但无法看到Imageview。

ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayOptions(actionBar.getDisplayOptions() | ActionBar.DISPLAY_SHOW_CUSTOM);
    ImageView imageView = new ImageView(actionBar.getThemedContext());
    imageView.setScaleType(ImageView.ScaleType.CENTER);
    imageView.setImageResource(R.drawable.amazon);
    ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(30, 30, Gravity.RIGHT | Gravity.CENTER_VERTICAL);
    layoutParams.rightMargin = 40;
    imageView.setLayoutParams(layoutParams);
    actionBar.setCustomView(imageView);

Answer 1

替换

ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(30, 30, Gravity.RIGHT | Gravity.CENTER_VERTICAL);

带

ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(
        ActionBar.LayoutParams.WRAP_CONTENT,
        ActionBar.LayoutParams.WRAP_CONTENT, Gravity.RIGHT
                | Gravity.CENTER_VERTICAL);

如何在android中的窗口默认操作栏中添加图像？
