我声明了一个count变量,我想在调用函数时增加count的值,当用户发送到主活动时,count再次变为零,但问题是当调用函数时,值增加了,但在另一个函数中没有增加。当函数被调用时,count的值会增加,但当我在另一个为零的函数中调用它时,count的值保持不变
package com.codewithosama.socialapp;
public class SetupActivity extends AppCompatActivity {
final static int gallery_pick = 1;
// Here I declare count
int count = 0;
// Remaining code
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_setup);
filePath.putFile(resultUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
final String downloadUrl = uri.toString();
// Here I am increasing value of count
usersRef.child("profile image").setValue(downloadUrl)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Intent selfIntent = new Intent(SetupActivity.this, SetupActivity.class);
startActivity(selfIntent);
Toast.makeText(SetupActivity.this, "Image Stored", Toast.LENGTH_SHORT)
.show();
loadingBar.dismiss();
count = count + 1;
Log.d("count", String.valueOf(count));
} else {
String message = task.getException().getMessage();
Toast.makeText(SetupActivity.this, "Error:" + message, Toast.LENGTH_SHORT)
.show();
loadingBar.dismiss();
}
}
});
}
});
}
});
}
// Remaining Code
private void saveAccountSetupInfo() {
Log.d("count", String.valueOf(count));
String user_name = userName.getText().toString();
String full_name = fullName.getText().toString();
String country = countryName.getText().toString();
// Log.d("uri",ImageUri.toString());
if (TextUtils.isEmpty(user_name)) {
Toast.makeText(this, "Please enter UserName ...", Toast.LENGTH_SHORT).show();
}
else if (count == 0) {
Toast.makeText(this, "Please select a profile Image", Toast.LENGTH_SHORT).show();
}
else if (TextUtils.isEmpty(full_name)) {
Toast.makeText(this, "Please enter Full Name ...", Toast.LENGTH_SHORT).show();
} else if (TextUtils.isEmpty(country)) {
Toast.makeText(this, "Please enter Country ...", Toast.LENGTH_SHORT).show();
} else {
usersRef.updateChildren(userMap).addOnCompleteListener(new OnCompleteListener() {
@Override
public void onComplete(@NonNull Task task) {
if (task.isSuccessful()) {
sendUserToMainActivity();
Toast.makeText(SetupActivity.this, "Your account updated successfully", Toast.LENGTH_SHORT)
.show();
loadingBar.dismiss();
} else {
String message = task.getException().getMessage();
Toast.makeText(SetupActivity.this, "Error occured :" + message, Toast.LENGTH_SHORT).show();
loadingBar.dismiss();
}
}
});
}
}
// Here I am again assinging value of count zero
private void sendUserToMainActivity() {
Intent mainIntent = new Intent(SetupActivity.this, MainActivity.class);
mainIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(mainIntent);
finish();
count = 0;
}
}

必须声明count globally public和static,例如:
public static int count = 0
. 通过这样做,您可以在另一个函数和另一个类中使用变量计数,方法是键入:SetupActivity.count
.
