Question

In Activity I have two ListViews but now I must to detect on what ListView user clicked.
I have added adapters and setOnItemClickListener(this); for each ListView.

@Override
public void onItemClick(AdapterView<?> a, View v, int i, long l) {
    switch (v.getId()) {
        case R.id.list_1:
            Toast.makeText(this, "111111111", 0).show();
            break;
        case R.id.list_2:
            Toast.makeText(this, "222222222", 0).show();
            break;
    }
}

But v.getId() returns -1

Answer 1

use a.getId() instead of v.getId()

i mean use AdapterView<?> a

switch (a.getId()) {
        case R.id.list_1:
            Toast.makeText(this, "111111111", 0).show();
            break;
        case R.id.list_2:
            Toast.makeText(this, "222222222", 0).show();
            break;
    }
