[Android]Intentの使用例

1.パラメータなしActivityジャンプ

Intent it = new Intent(Activity.Main.this, Activity2.class);
startActivity(it);

 
2.次のActivityにデータを渡す(BundleとIntent.putExtrasを使用)

Intent it = new Intent(Activity.Main.this, Activity2.class);
Bundle bundle=new Bundle();
bundle.putString("name", "This is from MainActivity!");
it.putExtras(bundle);       // it.putExtra(“test”, "shuju”);startActivity(it); 
// startActivityForResult(it,REQUEST_CODE);

 
データの取得には、次の操作を行います.

Bundle bundle=getIntent().getExtras();
String name=bundle.getString("name");

 
3.前のActivityに結果を返す(setResultを使用してstartActivity ForResult(it,REQUEST_CODE)で起動したActivity)

        Intent intent=getIntent();
        Bundle bundle2=new Bundle();
        bundle2.putString("name", "This is from ShowMsg!");
        intent.putExtras(bundle2);
        setResult(RESULT_OK, intent);

4.前のActivityの結果処理関数(onActivity Result)をコールバックする

@Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);      
  if (requestCode==REQUEST_CODE){          
      if(resultCode==RESULT_CANCELED)
          setTitle("cancle");     
          else if (resultCode==RESULT_OK) {
                 String temp=null;
                 Bundle bundle=data.getExtras();
                 if(bundle!=null) 
                  temp=bundle.getString("name");
                 setTitle(temp);
            }
        }
    }
