仿微信实现多图选择。支持单选和多选两种模式
./gradlew installDebug
第0步 把模块 multi-image-selector
作为你的项目依赖添加到工程中.
第1步 在你的 AndroidManifest.xml
文件中添加权限 android.permission.READ_EXTERNAL_STORAGE
. 别忘了同时在 AndroidManifest.xml
中声明 MultiImageSelectorActivity
和 PreviewPicturesActivity
这两个Activity.
<activity android:name="me.nereo.multi_image_selector.PreviewPicturesActivity" android:configChanges="orientation|screenSize" /> <activity android:name="me.nereo.multi_image_selector.MultiImageSelectorActivity" android:configChanges="orientation|screenSize" />
第2步 代码中调用,例如:
//yourActivity-Activity,requestCode-requestCode,maxNum-最多选择的图片数,selectedMode-选择模式(单选/多选) MultiImageSelectorActivity.startSelect(yourActivity, requestCode, maxNum, selectedMode);
第3步 在你的 onActivityResult
方法中接受结果. 例如:
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(requestCode == REQUEST_IMAGE){ if(resultCode == RESULT_OK){ // 获取返回的图片列表 List<String> path = data.getStringArrayListExtra(MultiImageSelectorActivity.EXTRA_RESULT); // 处理你自己的逻辑 .... } } }
第4步 没第4步了,就这样就OK啦~ :)
