傳達信息

Intent intent =new Intent(MainActivity.this,Main2Activity.class);

intent.putExtra("yl1","gisoracle");

//傳遞name參數為tinyphp
bundle.putString("yl2", "我愛你桂霞");
intent.putExtras(bundle);
startActivity(intent);

public class Main2Activity extends AppCompatActivity {

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);

    //獲取Intent攜帶數據
    Intent intent = getIntent();
    String index = intent.getStringExtra("yl1");

    //用Bundle攜帶數據
    Bundle bundle = getIntent().getExtras();
    String data = bundle.getString("yl2");//讀出數據

    Toast.makeText(this, index + "-" + data, Toast.LENGTH_SHORT).show();
