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); }
