我是从我的sqlitedatabase检索字符串数据和比较,以我的本地变量。但它不工作。它是这样C $ CS低于这个$。
I'm retrieving string data from my sqlitedatabase and compare in to my local variable. But its not working. It goes like this codes below.
String hole1 = " ";
Cursor cc = save.rawQuery("Select *from " +data + " where Mobile = '"+ number +"'", null);
cc.moveToFirst();
hole1 = cc.getString(cc.getColumnIndex("Hole1"));
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(
this,
R.layout.spinnerlayout,
new String[] { hole1,"1", "2", "3", "4","5","6","7","8","9" }); adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
((Spinner) findViewById(R.id.soloscorehole1front9)).setAdapter(adapter1);
if( ((Spinner) findViewById(R.id.soloscorehole1front9)).getSelectedItem().toString() == hole1){
Toast.makeText(Activity.this,"True!", Toast.LENGTH_LONG).show();
}
任何人都能指出什么是错的这个简单的codeS?
Can anyone point what is wrong with this simple codes?
推荐答案
您不应使用 ==
比较字符串。使用 string1.equals(字符串2)
代替。使用 ==
进行比较,如果参照每个字符串相等,而 .equals()
比较字符串的值
You shouldn't use ==
to compare strings. Use string1.equals(string2)
instead. Using ==
compares if the reference to each string is equal whereas .equals()
compares the values of the strings
