1. 启动一个新的Activity
- Intent it = new Intent(Activity.Main.this, Activity2.class);
- startActivity(it);
2. 向下一个Activity传递数据（使用Bundle和Intent.putExtras）
- 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);
对于数据 的获取可以采用：
- Bundle bundle=getIntent().getExtras();
- String name=bundle.getString("name");
3. 向上一个Activity返回结果（使用setResult，针对startActivityForResult(it,REQUEST_CODE)启动 的Activity）
- Intent intent=getIntent();
- Bundle bundle2=new Bundle();
- bundle2.putString("name", "This is from ShowMsg!");
- intent.putExtras(bundle2);
- setResult(RESULT_OK, intent);
4. 回调上一个Activity的结果处理函数（onActivityResult）
- @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);
- }
- }
- }
