两个Activities之间的数据传递问题解决1

//Main Activity        mSearchBtn.setOnClickListener(new OnClickListener() {public void onClick(View v) {intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);intent.setClass(getApplicationContext(), SearchActivity.class);//If you wanna get the values from the SearchActivity,//then,you have to set them "Before SearchActivity get them"!!!!bundle.putString("item", null);bundle.putString("category", null);bundle.putString("page",null);intent.putExtras(bundle);startActivityForResult(intent, 1);}});              }//onCreate        /**     *  Receive from the SearchActivity      *      *  @override     * **/        @Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode, data);switch(resultCode){case RESULT_OK:Log.d("return","Return OK!");/* Get result from SearchActivity */bundle = data.getExtras();String item = bundle.getString("item");String category = bundle.getString("category");String page = bundle.getString("page");Log.d("result","item-category-page="+item+category+page);break;default:break;}}

//SearchActivity.java

//Get the bundle in the intent        intent = this.getIntent();        bundle = intent.getExtras();        mBtn_back.setOnClickListener(new OnClickListener() {public void onClick(View v) {bundle.putString("item", "whatItem");bundle.putString("category", "whatCate");bundle.putString("page","whatPage");intent.putExtras(bundle);SearchActivity.this.setResult(RESULT_OK, intent);SearchActivity.this.finish();}});
