所以,有两个问题与此相同( How to use getCropAndSetWallpaperIntent method in WallpaperManager?和How to use getCropAndSetWallpaperIntent? ),但两者都没有答案。希望得到一个答案,我问这个 - 如何让这个方法起作用。
这不起作用
WallpaperManager wallpaperManager = WallpaperManager.getInstance(MainActivity.this);
Uri uri = Uri.parse("android.resource://lv.revo.inspicfootballhd/drawable/v1");
Intent intent = new Intent(wallpaperManager.getCropAndSetWallpaperIntent(uri));
startActivity(intent);
logcat显示了这个

因此,根据文档“将在意图中设置的图像URI。必须是内容URI,其提供者必须将其类型解析为”image / *“”
图像为.jpg格式。我明天会继续寻找解决方案。我只是希望更聪明的人知道我问题的答案。
编辑/更新1: 因此我设法将uri更改为Content Uri,我相信如此。这样做是使用了这个 - https://stackoverflow.com/a/23223556/2727408
现在它显示了这个
java.lang.IllegalArgumentException: Cannot use passed URI to set wallpaper; check that the type returned by ContentProvider matches image/*
at android.app.WallpaperManager.getCropAndSetWallpaperIntent(WallpaperManager.java:792)
at lv.revo.inspicfootballhd.MainActivity.onTouch(MainActivity.java:244)
我尝试使用ContentResolver getType(contentURI)检查类型,它返回null。现在我将尝试找到如何将其更改为image / *
到目前为止的代码看起来像这样
Uri uri = ResourceToUri(getApplicationContext(), imageArray[j]);
File wallpaper_file = new File(uri.getPath());
Uri contentURI = getImageContentUri(getApplicationContext(), wallpaper_file.getAbsolutePath());
ContentResolver cr = this.getContentResolver();
Log.d("CONTENT TYPE: ", "IS: " + cr.getType(contentURI));
Intent intent = new Intent(wallpaperManager.getCropAndSetWallpaperIntent(contentURI));
startActivity(intent);
到目前为止,谢谢。
编辑/更新2: 在这里创建了关于我的新问题的新问题: How to change type to image/*
答案 0 :(得分:1)
与错误一样,您需要一个内容URI。内容URI允许您共享具有临时读写权限的文件。
答案 1 :(得分:0)
File wallpaper_file = new File(uri.getPath());
Uri contentURI = getImageContentUri(getApplicationContext(),wallpaper_file);
ContentResolver cr = this.getContentResolver();
Log.d("CONTENT TYPE: ", "IS: " + cr.getType(contentURI));
Intent intent = new Intent(wallpaperManager.getCropAndSetWallpaperIntent(contentURI));
startActivity(intent);
public static Uri getImageContentUri(Context context, File imageFile) {
String filePath = imageFile.getAbsolutePath();
Cursor cursor = context.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
new String[]{MediaStore.Images.Media._ID},
MediaStore.Images.Media.DATA + "=? ",
new String[]{filePath}, null);
if (cursor != null && cursor.moveToFirst()) {
int id = cursor.getInt(cursor
.getColumnIndex(MediaStore.MediaColumns._ID));
Uri baseUri = Uri.parse("content://media/external/images/media");
return Uri.withAppendedPath(baseUri, "" + id);
} else {
if (imageFile.exists()) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA, filePath);
return context.getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
} else {
return null;
}
}
}
