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);
}
