//Later i will insert it in the database
Toast.makeText(getBaseContext(), "EditText Value, checkbox value and other values", Toast.LENGTH_SHORT).show();
}
});
}
private static final String[] country = { "item1", "item2", "item3",
"item4", "item5", "item6" };
private static final String[] curr = { "1", "2", "3", "4", "5", "6" };
}
推荐答案
尝试一下，
btnSave.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
for (int i = 0; i <l1.getCount() ; i++) {
View vListSortOrder;
vListSortOrder=l1.getChildAt(i);
try{
EditText edit=(EditText)vListSortOrder.findViewById(R.id.share_comment_edit);
String temp=edit.getText().toString();
}
}
});
类似地为您的CheckBox创建一个对象并获取其状态.简单的.
Similarly create a object for your CheckBox and get its state. Simple.
