如何使用Firebase中的文本上傳和檢索圖片？任何人都請告訴我可能的方法。

Answer 1

試試這個上傳的火力

FirebaseStorage mStorageRef = FirebaseStorage.getInstance(); 
String path = "uploadImage/" + UUID.randomUUID() + ".png"; 

// Get the data from an ImageView as bytes 
imageView.setDrawingCacheEnabled(true); 
imageView.buildDrawingCache(); 
Bitmap bitmap = imageView.getDrawingCache(); 
ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos); 
byte[] data = baos.toByteArray(); 

StorageReference storageReference = mStorageRef.getReference(path); 
UploadTask uploadTask = storageReference.putBytes(data); 
uploadTask.addOnFailureListener(new OnFailureListener() { 
@Override 
public void onFailure(@NonNull Exception exception) { 
    // Handle unsuccessful uploads 
} 
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() { 
@Override 
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { 
    // taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL. 
    // your download uri 
    Uri downloadUrl = taskSnapshot.getDownloadUrl(); 
} 
});
