Android Intent传递对象和集合

Article article = JsonUtils.getArticle(content);          
intent = new Intent(activity, CompositionCorrect.class);         
 Bundle bundle = new Bundle();          
bundle.putSerializable("ARTICLE", article);          
intent.putExtras(bundle);          
startActivity(intent);

获取传递的对象
private void initIntentData() {    
intent = getIntent();    
article = (Article) intent.getSerializableExtra("ARTICLE");    
tv_content.setText("" + article.getContent());    
spannableStringBuilder = new SpannableStringBuilder(tv_content.getText().toString());  
}
传递集合
intent = new Intent(CompositionCorrectActivity.this,PiGaiCompletedActivity.class);             
Bundle bundle = new Bundle();             
for (int i = 0; i < mSpansCommit.size(); i++) {            
mSpansCommit.get(i).setColorSpan(null);             
}           
bundle.putSerializable("MSPANSCOMMIT", (Serializable)mSpansCommit);           
bundle.putSerializable("ARTICLE", article);          
intent.putExtras(bundle);           
startActivity(intent);
获取集合
mSpansCommit = (List<Span>) intent.getSerializableExtra("MSPANSCOMMIT");
