How can I call another activity from one (the current) activity?
Use the Intent to call another Activity. In the Manifest, you should add
<activity android:name="ListViewImage"></activity> <activity android:name="com.company.listview.ListViewImage"> </activity>
And in your current activity,
btListe = (ImageButton)findViewById(R.id.Button_Liste);
btListe.setOnClickListener(new OnClickListener()
{ public void onClick(View v)
{
intent = new Intent(main.this, ListViewImage.class);
startActivity(intent);
finish();
}
});
Passing Parameter
And for the same I want to call an activity which contains a dialog message box from my current activity.
sendButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
String valueString = editValue.getText().toString();
long value;
if (valueString != null) {
value = Long.parseLong(valueString);
}
else {
value = 0;
}
Bundle sendBundle = new Bundle();
sendBundle.putLong("value", value);
Intent i = new Intent(Activity1.this, Activity2.class);
i.putExtras(sendBundle);
startActivity(i);
finish();
}
});
and in Activity2:
Bundle receiveBundle = this.getIntent().getExtras();
final long receiveValue = receiveBundle.getLong("value");
receiveValueEdit.setText(String.valueOf(receiveValue));
callReceiverButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(Activity2.this, Receiver.class);
i.putExtra("new value", receiveValue - 10);
}
});
