android 本地资源 uri,Android 本地文件选择
打開系統(tǒng)文件：
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(Intent.createChooser(intent, getString(R.string.im_text_select_file)), SEND_NORMAL_FILE);
} catch (android.content.ActivityNotFoundException ex) {
BAUtil.showToast(this, "未找到文件管理應(yīng)用，請安裝文件管理應(yīng)用后再試");
}
回調(diào)方法：
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case SEND_NORMAL_FILE:
try {
String path = "";
if (Build.VERSION.SDK_INT >= 19) {
path = handleImageOnKitKat(context, data);
} else {
path = handleImageBeforeKitKat(context, data);
}
doSendNormalFile(path, BAAttach.TYPE_FILE);
} catch (Exception e) {
e.printStackTrace();
}
break;
}
}
@TargetApi(Build.VERSION_CODES.KITKAT)
public static String handleImageOnKitKat(Context context, Intent data) {
Uri uri = data.getData();
if (DocumentsContract.isDocumentUri(context, uri)) {
String docId = DocumentsContract.getDocumentId(uri);
if ("com.android.providers.media.documents".equals(uri.getAuthority())) {
String id = docId.split(":")[1];
String selection = MediaStore.Images.Media._ID + "=" + id;
String type = docId.split(":")[0];
Uri contentUri = null;
if (type.equalsIgnoreCase("image")) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if (type.equalsIgnoreCase("audio")) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
} else if (type.equalsIgnoreCase("video")) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
}
return getImagePath(context, contentUri, selection);
} else if ("com.android.providers.media.downloads.documents".equals(uri.getAuthority())) {
Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"),
Long.valueOf(docId));
return getImagePath(context, contentUri, null);
} else if ("content".equals(uri.getAuthority())) {
return getImagePath(context, uri, null);
} else if ("file".equals(uri.getAuthority())) {
return uri.getPath();
}
}
return "";
}
public static String handleImageBeforeKitKat(Context context, Intent data) {

return getImagePath(context, uri, null);
}
private static String getImagePath(Context context, Uri uri, String selection) {

if (cursor != null) {
if (cursor.moveToFirst()) {

}
return path;
}
