Passing different data through Intent in Activity
suggest change1. Passing integer data:
SenderActivity
Intent myIntent = new Intent(SenderActivity.this, ReceiverActivity.class);
myIntent.putExtra("intVariableName", intValue);
startActivity(myIntent);
ReceiverActivity
Intent mIntent = getIntent();
int intValue = mIntent.getIntExtra("intVariableName", 0); // set 0 as the default value if no value for intVariableName found
2. Passing double data:
SenderActivity
Intent myIntent = new Intent(SenderActivity.this, ReceiverActivity.class);
myIntent.putExtra("doubleVariableName", doubleValue);
startActivity(myIntent);
ReceiverActivity
Intent mIntent = getIntent();
double doubleValue = mIntent.getDoubleExtra("doubleVariableName", 0.00); // set 0.00 as the default value if no value for doubleVariableName found
3. Passing String data:
SenderActivity
Intent myIntent = new Intent(SenderActivity.this, ReceiverActivity.class);
myIntent.putExtra("stringVariableName", stringValue);
startActivity(myIntent);
ReceiverActivity
Intent mIntent = getIntent();
String stringValue = mIntent.getExtras().getString("stringVariableName");
or
Intent mIntent = getIntent();
String stringValue = mIntent.getStringExtra("stringVariableName");
4. Passing ArrayList data :
SenderActivity
Intent myIntent = new Intent(SenderActivity.this, ReceiverActivity.class);
myIntent.putStringArrayListExtra("arrayListVariableName", arrayList);
startActivity(myIntent);
ReceiverActivity
Intent mIntent = getIntent();
arrayList = mIntent.getStringArrayListExtra("arrayListVariableName");
5. Passing Object data :
SenderActivity
Intent myIntent = new Intent(SenderActivity.this, ReceiverActivity.class);
myIntent.putExtra("ObjectVariableName", yourObject);
startActivity(myIntent);
ReceiverActivity
Intent mIntent = getIntent();
yourObj = mIntent.getSerializableExtra("ObjectVariableName");
Note : Keep in mind your custom Class must implement the Serializable interface.
6. Passing HashMap<String, String> data :
SenderActivity
HashMap<String, String> hashMap;
Intent mIntent = new Intent(SenderActivity.this, ReceiverActivity.class);
mIntent.putExtra("hashMap", hashMap);
startActivity(mIntent);
ReceiverActivity
Intent mIntent = getIntent();
HashMap<String, String> hashMap = (HashMap<String, String>)
mIntent.getSerializableExtra("hashMap");
7. Passing Bitmap data :
SenderActivity
Intent myIntent = new Intent(SenderActivity.this, ReceiverActivity.class);
myIntent.putExtra("image",bitmap);
startActivity(mIntent);
ReceiverActivity
Intent mIntent = getIntent();
Bitmap bitmap = mIntent.getParcelableExtra("image");
Found a mistake? Have a question or improvement idea?
