android中的Intent表單活動穿梭

標籤：intent

活動之間的互相訪問使用Intent

Intent顯示訪問通過按鈕定義

button1.setOnClickListener(View.OnClickListener(){        onClick(View v){Intent intent=Intent(MainActivity.,second_Activity.);            startActivityForResult(intent,);        }});Intent的隱示穿梭並不指定具體的穿梭對象，指定了一系列action和category等資訊，然後系統分析找出合適的活動啟動，並且需要在AndroidManifest中設定檔button1.setOnClickListener(new View.OnClickListener(){        public void onClick(View v){           Intent intent=new Intent("come.example.wcx.myapplication.ACTION_START");           intent.addCategory("come.example.wcx.myapplication.Category");            startActivity(intent);            Intent intent=new Intent(Intent.ACTION_DIAL);            intent.setData(Uri.parse("tel:10086"));            startActivity(intent);                }});Intent進行資料的傳遞button1.setOnClickListener(new View.OnClickListener(){        public void onClick(View v){                       String data="Hello second";            Intent intent=new Intent(MainActivity.this,second_Activity.class);            intent.putExtra("Extra_String",data);            startActivity(intent);        }}); 接收資料的活動 Intent intent=getIntent();final String hello=intent.getStringExtra("Extra_String"); Log.d("second_Activity",hello);   Intent回調資料

button1.setOnClickListener(View.OnClickListener(){        onClick(View v){Intent intent=Intent(MainActivity.,second_Activity.);            startActivityForResult(intent,);

}}

onActivityResult(requestCode,resultCode,Intent data){    (requestCode)    {        : (requestCode==){           String d=data.getStringExtra();            Log.(,d);        }        ;        :    }}

button2.setOnClickListener(View.OnClickListener() {    onClick(View v) {        Intent intent=Intent();        intent.putExtra(,);        setResult(,intent);        finish();    }});
