35 |
36 | ## 常见问题
37 |
38 | 1. 结合 Fresco 加载图片请参考 [FrescoDemoActivity](https://github.com/bingoogolapple/BGABanner-Android/blob/master/demo/src/main/java/cn/bingoogolapple/bgabanner/demo/ui/activity/FrescoDemoActivity.java)
39 | 2. 自定义 item 布局文件请参考 [FrescoDemoActivity](https://github.com/bingoogolapple/BGABanner-Android/blob/master/demo/src/main/java/cn/bingoogolapple/bgabanner/demo/ui/activity/FrescoDemoActivity.java)
40 |
41 | ## 使用
42 |
43 | ### 1.添加 Gradle 依赖
44 |
45 | * 把 `maven { url 'https://jitpack.io' }` 添加到 root build.gradle 的 repositories 中
46 | * 在 app build.gradle 中添加如下依赖，末尾的「latestVersion」指的是徽章 [](https://jitpack.io/#bingoogolapple/BGABanner-Android) 里的版本名称，请自行替换
47 |
48 | ```groovy
49 | implementation 'androidx.legacy:legacy-support-v4:latestVersion'
50 | implementation 'com.github.bingoogolapple:BGABanner-Android:latestVersion'
51 | ```
52 |
53 | ### 2.在布局文件中添加 BGABanner
54 |
55 | ```xml
56 |
65 | ```
66 |
67 | ### 3.在 Activity 或者 Fragment 中配置 BGABanner 的数据源
68 |
69 | 有多种配置数据源的方式，这里仅列出三种方式。更多初始化方式请查看 [demo](https://github.com/bingoogolapple/BGABanner-Android/tree/master/demo)
70 |
71 | >配置数据源的方式1：通过传入数据模型并结合 Adapter 的方式配置数据源。这种方式主要用于加载网络图片，以及实现少于3页时的无限轮播
72 |
73 | ```java
74 | mContentBanner.setAdapter(new BGABanner.Adapter() {
75 | @Override
76 | public void fillBannerItem(BGABanner banner, ImageView itemView, String model, int position) {
77 | Glide.with(MainActivity.this)
78 | .load(model)
79 | .placeholder(R.drawable.holder)
80 | .error(R.drawable.holder)
81 | .centerCrop()
82 | .dontAnimate()
83 | .into(itemView);
84 | }
85 | });
86 |
87 | mContentBanner.setData(Arrays.asList("网络图片路径1", "网络图片路径2", "网络图片路径3"), Arrays.asList("提示文字1", "提示文字2", "提示文字3"));
88 | ```
89 |
90 | > 配置数据源的方式2：通过直接传入视图集合的方式配置数据源，主要用于自定义引导页每个页面布局的情况
91 |
92 | ```java
93 | List views = new ArrayList<>();
94 | views.add(View.inflate(context, R.layout.layout_guide_one, null));
95 | views.add(View.inflate(context, R.layout.layout_guide_two, null));
96 | views.add(View.inflate(context, R.layout.layout_guide_three, null));
97 | mContentBanner.setData(views);
98 | ```
99 |
100 | > 配置数据源的方式3：通过传入图片资源 id 的方式配置数据源，主要用于引导页每一页都是只显示图片的情况
101 |
102 | ```
103 | // Bitmap 的宽高在 maxWidth maxHeight 和 minWidth minHeight 之间
104 | BGALocalImageSize localImageSize = new BGALocalImageSize(720, 1280, 320, 640);
105 | // 设置数据源
106 | mContentBanner.setData(localImageSize, ImageView.ScaleType.CENTER_CROP,
107 | R.drawable.uoko_guide_background_1,
108 | R.drawable.uoko_guide_background_2,
109 | R.drawable.uoko_guide_background_3);
110 | ```
111 |
112 | ### 4.监听广告 item 的单击事件，在 BGABanner 里已经帮开发者处理了防止重复点击事件
113 |
114 | ```java
115 | mContentBanner.setDelegate(new BGABanner.Delegate() {
116 | @Override
117 | public void onBannerItemClick(BGABanner banner, ImageView itemView, String model, int position) {
118 | Toast.makeText(banner.getContext(), "点击了" + position, Toast.LENGTH_SHORT).show();
119 | }
120 | });
121 | ```
122 |
123 | ### 5.设置「进入按钮」和「跳过按钮」控件资源 id 及其点击事件，如果进入按钮和跳过按钮有一个不存在的话就传 0，在 BGABanner 里已经帮开发者处理了防止重复点击事件，在 BGABanner 里已经帮开发者处理了「跳过按钮」和「进入按钮」的显示与隐藏
124 |
125 | ```java
126 | mContentBanner.setEnterSkipViewIdAndDelegate(R.id.btn_guide_enter, R.id.tv_guide_skip, new BGABanner.GuideDelegate() {
127 | @Override
128 | public void onClickEnterOrSkip() {
129 | startActivity(new Intent(GuideActivity.this, MainActivity.class));
130 | finish();
131 | }
132 | });
133 | ```
134 |
