Activity中Bundle传递数据

发送端：

                Intent intent = new Intent(MainActivity.this,FirstActivity.class);
                Bundle data = new Bundle();
                data.putString(NAME_KEY,"zhangsan");//将数据放入bundle
                data.putInt(AGE_KEY,25);
                data.putBoolean(IS_FEMALE_KEY,false);
                intent.putExtras(data);
                startActivity(intent);

接收端：

 Bundle data = getIntent().getExtras();//从bundle中取出数据
                String name = data.getString(NAME_KEY);
                int age = data.getInt(AGE_KEY);
                boolean isfemale = data.getBoolean(IS_FEMALE_KEY);
                Log.d("TAG","waname = "+name);
                Log.d("TAG","waage = "+age);
                Log.d("TAG","waisfemale = "+isfemale);

     /*   Bundle bundle = getIntent().getExtras();    //得到传过来的bundle
        boolean data = bundle.getBoolean("isConnected");
        button2.setText("MainActivity连接=="+data);*/
                button2.setText("连接=="+"waname = "+name+"waage = "+age+"waisfemale = "+isfemale);
