软件界面
功能需求
跟普通的文件管理器一样,读取内置存储或者U盘文件显示出来.包含:文件类型区分,打开,增删改查,多选,排序
适配器代码

加载是分段加载的,每次加载30条数据,下拉继续加载,本来文件名过长想用跑马灯显示的,这反而导致了不断让RecyclerView去刷新 不断去跑OnCreateHolder()方法,导致很卡,所以删掉了TextView android:ellipsize="marquee"属性.
调用打开部分代码
/**
* 图片用自带软件打开
* @param context 上下文
* @param file 文件对象
* @param list 图片列表
*/
public static void openPicture(Context context, XZFile file, List<XZFile> list) {
try {
EventBus.getDefault().postSticky(list);
Intent intent = new Intent(context, BrowseImageActivity.class);
intent.putExtra("image_index", file.getPath());
context.startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
Utils.showToast(context, R.string.no_app_can_open);
}
}
用Viewpager写的图片浏览器 方便左右切换 旋转图片
/**
* 音乐用自带软件打开
* @param context 上下文
* @param file 文件对象
*/
private static void openAudio(Context context, XZFile file) {
Uri uri = null;
Intent intent = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
//Android7.0后intent不能直接传路径
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
uri = Uri.fromFile(file.getFile());
intent = new Intent("android.intent.action.VIEW");
} else{
uri = Uri.fromFile(file.getFile());
intent = new Intent("android.intent.action.VIEW");
ComponentName componentName = new ComponentName("com.jrm.localmm", "com.jrm.localmm.ui.music.MusicPlayerActivity");
intent.setComponent(componentName);
}
intent.setDataAndType(uri, "audio");
context.startActivity(intent);
}
/**
* 视频用自带软件打开
* @param context 上下文
* @param file 文件对象
*/
private static void openVideo(Context context, XZFile file) {
Uri uri = null;
Intent intent = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
uri = Uri.fromFile(file.getFile());
intent = new Intent("android.intent.action.VIEW");
intent.setClassName("com.hisilicon.android.videoplayer",
"com.hisilicon.android.videoplayer.activity.VideoActivity");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
} else{
uri = Uri.fromFile(file.getFile());

intent.setDataAndType(uri, "video/*");

}
主要是兼容不同平台 Mstar方案 海思方案
第一次写,写得不好QAQ
