#### 安装教程

1.在项目根目录下的build.gradle文件中，
 ```
 allprojects {
    repositories {
        maven {
            url 'https://s01.oss.sonatype.org/content/repositories/snapshots/'
        }
    }
 }
```
2.在entry模块的build.gradle文件中，
 ```
 dependencies {
    implementation('com.gitee.chinasoft_ohos:FilePicker:0.0.1-SNAPSHOT')
    ......
 }
```
在sdk6，DevEco Studio 2.2 beta1下项目可直接运行 如无法运行，
删除项目.gradle,.idea,build,gradle,build.gradle文件， 
并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

#### 使用说明

1、首先创建一个DialogProperties：
 ```
 DialogProperties properties = new DialogProperties();
```
2、使用DialogConfig类为每个对话框属性赋值。
```
      properties.selection_mode = DialogConfigs.SINGLE_MODE;
      properties.selection_type = DialogConfigs.FILE_SELECT;
      properties.root = new File(DialogConfigs.DEFAULT_DIR);
      properties.error_dir = new File(DialogConfigs.DEFAULT_DIR);
      properties.offset = new File(DialogConfigs.DEFAULT_DIR);
      properties.extensions = null;
      properties.show_hidden_files = false;
```
3、接下来，在点击显示Dialog时，创建实例FilePickerDialog。
```
     FilePickerDialog dialog = new FilePickerDialog(this, properties);
     dialog.setTitle("Select a File");
     dialog.setPositiveBtnName("Select");
     dialog.setNegativeBtnName("Cancel");
     dialog.onStart();
     dialog.show();
```
4、接下来，添加DialogSelectionListener到FilePickerDialog如下：
```
dialog.setDialogSelectionListener((files) -> {
                int size = listItem.size();
                listItem.clear();
                mFileListAdapter.notifyDataSetItemRangeRemoved(0, size);
                for (String path : files) {
                    File file = new File(path);
                    ListItem item = new ListItem();
                    item.setName(file.getName());
                    item.setPath(file.getCanonicalPath());
                    listItem.add(item);
                }
                mFileListAdapter.notifyDataSetItemRangeInserted(0, listItem.size());
                fileList.setHeight(listItem.size() * 150);
            });
```
