启动Activity，传递参数最佳实践

优化后的好处不言而喻，OtherActivity中所需要的参数都在方法参数中体现，减少了交流询问的成本。

（1）MainActivity.java

OtherActivity.openActivity(getActivity(), "yanshiying","25");

（2）OtherActivity.java

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_other);

        btnBackActivity = (Button)findViewById(R.id.btnBackActivity);

        btnBackActivity.setOnClickListener(btnClickListener());

        Bundle bundle = getIntent().getExtras();
        if(bundle!=null){
            Log.d("OtherActivity name:", bundle.getString("name"));
            Log.d("OtherActivity age:", bundle.getString("age"));
        }
    }

    public static void openActivity(Context context,String name,String age){
        Intent intent = new Intent(context, OtherActivity.class);
        intent.putExtra("name", name);
        intent.putExtra("age", age);
        context.startActivity(intent);
    }
