java - 将2个变量传递给passedView

Question

我似乎无法理解这一点。我试图将两个字符串传递给一项新 Activity ，但只能传递一个字符串。有人可以帮忙吗？我希望传递的字符串表示“我想要” movieName movieGroup “everyday”

public class Main22Activity extends AppCompatActivity {
String passedVar=null;
private TextView passedView= null;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main22);
    Bundle extras = getIntent().getExtras();
    passedVar=getIntent ().getStringExtra(MainActivity.ID_EXTRA + "movieName");
    passedVar2=getIntent ().getStringExtra(MainActivity.ID_EXTRA + "movieGroup");
    passedView = (TextView) findViewById(R.id.textView3);
    passedView.setText("I would like  " + passedVar, passedVar2 + "everyday");


}

Answer 1

public class Main22Activity extends AppCompatActivity {
   String passedVar=null;
   String passedVar2=null;
   private TextView passedView= null;

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main22);
  Bundle extras = getIntent().getExtras();
  passedVar=getIntent ().getStringExtra(MainActivity.ID_EXTRA +"movieName");
  passedVar2=getIntent ().getStringExtra(MainActivity.ID_EXTRA + "movieGroup");
  passedView = (TextView) findViewById(R.id.textView3);
  passedView.setText("I would like " + passedVar + "," + passedVar2 + "everyday");
}

注意变化

passedVar + "," + passedVar2
