        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                DatabaseAccounts dbAccount = data.get(position);


                Intent intent = new Intent(getApplicationContext(),Diary2.class);

                startActivity(intent);

            }
        });

        for(DatabaseAccounts dbb : data){
            mArrayList.add(dbb.getState());
        }
        mArrayAdapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,mArrayList);
        list.setAdapter(mArrayAdapter);

您可以在JavaScript中尝试：

echo "<script>

setTimeout(function () {
    alert('Session Timeout. Please Re-Login');
    window.location.href='index.php';
}, 300000);

</script>";

希望这有帮助，谢谢！
