未兼容Androidx，后续版本为改为兼容androidx版本
gradle引入
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}当前版本
dependencies {
implementation 'com.github.itdais:FilePicker:1.0.0'
}<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />注意：如果您想兼容Android N或者以上的设备，必须要在AndroidManifest.xml文件中配置FileProvider来访问共享路径的文件
<!-- 解决provider部分在库manifest文件merge时的问题 -->
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true"
tools:replace="name,authorities,exported,grantUriPermissions">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"
tools:replace="name,resource" />
</provider>如果第三方库也配置了同样的FileProvider, 可以通过继承FileProvider类来解决合并冲突的问题，示例如下：
<provider
android:name=".MyFileProvider"
android:authorities="${applicationId}.fileProvider"
android:exported="false"
android:grantUriPermissions="true"
tools:replace="name,authorities,exported,grantUriPermissions">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"
tools:replace="name,resource"/>
</provider>对应的provider_paths.xml文件
<paths>
<external-path
name="external_files"
path="." />
</paths>int requestCode = 1006;
FilePicker.from(MainActivity.this).chooseFile()
.setFileType(".txt")
.start(requestCode);设置默认路径
int requestCode = 1006;
FilePicker.from(MainActivity.this).chooseFile()
.setFileType(".txt")
.setTargetPath(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "Mypda/test")
.start(requestCode);设置样式
int requestCode = 1006;
FilePicker.from(MainActivity.this).chooseFile()
.setFileType(".txt")
.setThemeId(R.style.Mystyle)
.start(requestCode);如需使用请白底黑字的toolbar样式,需要自定义Style继承FilePicker.Default,修改toolbar的样式为
<style name="Mystyle" parent="FilePicker.Default">
<item name="fp.toolbar">@style/Toolbar.Light</item>
</style>内部定义了白底黑字的toolbar样式,如下
定义的属性有
<attr name="fp.toolbar" format="reference" />
<attr name="fp.placeholder" format="reference|color" />
<attr name="fp.emptyView" format="reference" />
<attr name="fp.emptyView.textColor" format="reference|color" />
<attr name="fp.pageBg" format="reference|color" />
<attr name="fp.item.textcolor" format="reference|color" />
<attr name="fp.item.hintcolor" format="reference|color" />
<attr name="fp.item.pathcolor" format="reference|color" />系统对应的样式
