CheckBox isSelected() method always returns false

Question

I am working on an Android application where I have to check the CheckBox selection onClick() so I made this

                if (checkBoxRM.isSelected() == true) {
                isSelectedValue = "True";
                //debug
                Toast.makeText(MainActivity.this, "Kiejölés értéke: " + isSelectedValue, Toast.LENGTH_SHORT).show();
            } else {
                //debug
                isSelectedValue = "False";
                Toast.makeText(MainActivity.this, "Kiejölés értéke: " + isSelectedValue, Toast.LENGTH_SHORT).show();
            }

But seems like isSelectedValue is always false .

Answer 1

而不是isSelected()执行isChecked() 。

Answer 2

You have to cast the checkBox to enable isChecked()

This works:

boolean selected = ((CheckBox)view.findViewById(R.id.main_cbSelectAll)).isChecked();

This not (here, you can only choose "isSelected"):

boolean selected = view.findViewById(R.id.main_cbSelectAll).isChecked();

If you want to use it as an SQLite-statement, you have to transform to an integer:

int selected = ((CheckBox)view.findViewById(R.id.main_cbSelectAll)).isChecked() ? 1 : 0;
