私は1つの編集テキストがあるアンドロイドアプリを開発しています...最初の編集テキストはユーザーの名を与えることです..ユーザーの名などの文字が入力されます...そして文字ごとに異なる値が与えられます...これらすべての値を追加する方法についての私の質問....?
各文字を個別に取得する方法...そして配列に入れ、そのすべての値を追加します
public class MainActivity extends Activity {
Button btn1;
EditText et1, et2, et3, et4, et5, et6;
Spinner sp1,sp2,sp3;
TextView txt1,txt2,txt3,txt4,txt5,txt6,txt7,txt8,txt9,txt10;
String month,day,year;
int sum;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void calc(View v)
{
EditText et1 = (EditText) findViewById (R.id.editText1);
/*TextView txt1 = (TextView) findViewById ( R.id.textView88);*/
sum=getSum(et1.getText().toString());
Intent i=new Intent(MainActivity.this, result.class);
i.putExtra("name", sum);
startActivity(i);
/*txt1.setText(sum + "");*/
}
private int getSum(String text)
{
// TODO Auto-generated method stub
int sum = 0;
char[] name = new char[text.length()];
name = text.toCharArray();
for(int i=0; i<text.length(); i++)
{
sum += value( name[i] );
}
while (sum>9)
{
sum = findDigitSum(sum);
}
return sum;
}
public int findDigitSum(int n)
{
int sum = 0;
while (n != 0)
{
sum += n % 10;
n = n / 10;
}
return sum;
}
private int value(char a) {
// TODO Auto-generated method stub
switch(a) {
case 'A':
return 1;
case 'B':
return 2;
case 'C':
return 3;
case 'D':
return 4;
case 'E':
return 5;
case 'F':
return 6;
case 'G':
return 7;
case 'H':
return 8;
case 'I':
return 9;
case 'J':
return 1;
case 'K':
return 2;
case 'L':
return 3;
case 'M':
return 4;
case 'N':
return 5;
case 'O':
return 6;
case 'P':
return 7;
case 'Q':
return 8;
case 'R':
return 9;
case 'S':
return 1;
case 'T':
return 2;
case 'U':
return 3;
case 'V':
return 4;
case 'W':
return 5;
case 'X':
return 6;
case 'Y':
return 7;
case 'Z':
return 8;
default:
return 0;
}
}
}
2 番目のアクティビティ result.java
public class result extends Activity {
TextView txt2;
/*private Intent getIntent;*/
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.result_xm);
TextView txt2 = (TextView) findViewById(R.id.textView2);
txt2.setText(getIntent().getStringExtra("name"));
/*Intent iin= getIntent();
Bundle b = iin.getExtras();
if(b!=null)
{
String name = getIntent.getStringExtra("name");
txt2.setText(name);
}*/
}
}
