推荐答案
其实你必须要么维持从 addMateria（视图V）的TextView的ID 或直接使用的TextView 。
Actually you have to either maintain TextView's ID from addMateria(View v) or use direct TextView.
有很多方法可以保持它一样，类级变量等。
There are many ways to keep it like, class level variables etc.,
一样，声明的TextView 作为类级别成员字段。
Like, declare TextView as a Class level member field.
public class ActivitySetOrario extends ActionBarActivity {
//Static perch� cosi non perdo i dati inseriti in precedenza!
static DataBase DB = new DataBase();
int clickedTextViewId; // Declare TextViewId as class level member field
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_set_orario);
}/
现在，拿在 addMateria（视图V）点击的TextView到mTextView参考
public void addMateria(View v){
//To get ID of your TextView do this
if(v instanceOf TextView)
{
clickedTextViewId = v.getId();
}
//StartActivityForResult perche mi aspetto la materia inserita dall'altra activity
Intent myIntent = new Intent(ActivitySetOrario.this, ActivityAddMateria.class);
ActivitySetOrario.this.startActivityForResult(myIntent, 1);
}
再次访问 mTextView 在的onActivityResult（），以更新颜色和文本
//Prende indietro la materia aggiunta dall'ActivityAddMateria
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == RESULT_OK){
String result = data.getStringExtra("result"); //Take the materia from Dialog
int color = data.getIntExtra("color",1); //Take the color from Dialog
Materia materia;
materia = new Materia();
materia.setMateria(result); //put the name materia into class materia
materia.setColor(color); //put the color materia into class materia
DB.getMaterie().add(materia);
// Now use mTextView here
try
{
View view = findViewById(clickedTextViewId);
if(view instanceOf TextView)
{
TextView textView = (TextView) view;
textView .setText(result);
textView .setBackgroundColor(color);
}
}catch(Exception ex)
{
ex.printStacktrace();
}
}
if (resultCode == RESULT_CANCELED) {
//Nessuna materia inserita
}
}//onActivity
