适配小米设备获取系统相片出问题

这两天跟小米壳上了。 其他android设备都好用。只有小米出问题。 并且不同的小米型号处理也不一样。 真是有些苦恼！ 在这记录一下解决的方法。

1：拍照获取图片之后没有相应。原因 intent.putExtra(“return-data”, true); miui系统默认的裁剪图片可能裁剪得过大，或对return-data分配的资源不足，造成return-data失败。

修改方式：

Intent intent = new Intent(“com.android.camera.action.CROP”);
intent.setDataAndType(uri, “image/*”);
intent.putExtra(“crop”, “true”);
intent.putExtra(“aspectX”, 1);
intent.putExtra(“aspectY”, 1);
intent.putExtra(“outputX”, 100);
intent.putExtra(“outputY”, 100);
uritempFile = Uri.parse(“file://” + “/” + Environment.getExternalStorageDirectory().getPath() + “/” +
“small.jpg”);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uritempFile);
intent.putExtra(“outputFormat”, Bitmap.CompressFormat.JPEG.toString());
instance.startActivityForResult(intent, PHOTORESOULT);

2.从系统相册获取图片返回data = null；
解决方式：

Intent innerIntent = new Intent(); //
“Android.intent.action.GET_CONTENT” if (Build.VERSION.SDK_INT < 19)
{ innerIntent.setAction(Intent.ACTION_GET_CONTENT);
innerIntent.setType(“image/"); } else { innerIntent = new
Intent(Intent.ACTION_PICK,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
innerIntent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
"image/”); }
Intent wrapperIntent = Intent.createChooser(innerIntent, null);
startActivityForResult(wrapperIntent, PHOTOZOOM);

3.解决返回图片路径有的小米系统地址不对

public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == NONE)
return;
if (requestCode == PHOTOZOOM) {
Uri uri = null;
if (data != null && data.getData() != null) {//
有數據返回直接使用返回的圖片地址
uri = data.getData();
String str = getPath(this, uri); // Toast.makeText(Cocos2dxActivity.getContext(),
// “PATH:”+str, Toast.LENGTH_LONG).show();
File picture = new File(str);
startPhotoZoom(Uri.fromFile(picture));
}
}
}

public static String getPath(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >=
Build.VERSION_CODES.KITKAT;
// DocumentProvider if (isKitKat &&
DocumentsContract.isDocumentUri(context, uri)) { //
ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split("?;
final String type = split[0];
if (“primary”.equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + “/”
+ split[1];
}
} // DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
final Uri contentUri =ContentUris.withAppendedId(Uri.parse(“content://downloads/public_downloads”),Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
} // MediaProvider
else if (isMediaDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split("?;
final String type = split[0];
Uri contentUri = null;
if (“image”.equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if (“video”.equals(type)) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
} else if (“audio”.equals(type)) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
}
final String selection = “_id=?”;
final String[] selectionArgs = new String[] { split[1] };
return getDataColumn(context, contentUri, selection,selectionArgs);
}
} // MediaStore (and general)
else if (“content”.equalsIgnoreCase(uri.getScheme())) {
return getDataColumn(context, uri, null, null); } // File
else if
(“file”.equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}

public static String getDataColumn(Context context, Uri uri,String selection, String[] selectionArgs) {
Cursor cursor = null;
final String column = “_data”;
final String[] projection = {
column };
try {
cursor = context.getContentResolver().query(uri,projection,selection, selectionArgs, null);
if (cursor != null && cursor.moveToFirst()) {
final int column_index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(column_index);
}
}
finally {
if (cursor != null) {
cursor.close();
}
}
return null;
}

public static boolean isExternalStorageDocument(Uri uri) {
return “com.android.externalstorage.documents”.equals(uri.getAuthority());
}

public static boolean isDownloadsDocument(Uri uri) {
return “com.android.providers.downloads.documents”.equals(uri .getAuthority());
}

public static boolean isMediaDocument(Uri uri) {
return “com.android.providers.media.documents”.equals(uri.getAuthority());
}
