我正在尝试从目录中删除图像,但是当我使用该方法时,它返回false
Locale
我一直在收集其他帖子的示例,但没有一个适合我
清单:
public void deleteImage() {
String file_path = Environment.getExternalStorageDirectory() + "/Angular/JPEG_20181010_282_9_320446411.jpg";
//Result Path: /storage/emulated/0/Angular/JPEG_20181010_282_9_320446411.jpg
File fdelete = new File(file_path);
if (fdelete.exists()) {
if (fdelete.delete()) { //This return false
Log.e("-->", "file Deleted :" + file_path );
} else {
Log.e("-->", "file not Deleted :" + file_path );
}
}
}
答案 0 :(得分:0)
将逻辑和方法更改为:
public void deleteImage() {
String file_path = Environment.getExternalStorageDirectory() + "/Angular/JPEG_20181010_282_9_320446411.jpg";
//Result Path: /storage/emulated/0/Angular/JPEG_20181010_282_9_320446411.jpg
File fdelete = new File(file_path);
if (fdelete.exists()) {
fdelete.delete() // delete the file here
Log.e("-->", "Success, file Deleted :" + file_path);
} else {
Log.e("-->", "file not Deleted :" + file_path);
}
}
exists()
将检查它是否存在,不需要额外的条件。
最好在try-catch
内添加代码,以便将来捕获所有情况。 (没有权限或任何错误)
