传达信息

Intent intent =new Intent(MainActivity.this,Main2Activity.class);
 
intent.putExtra("yl1","gisoracle");
 
//用Bundle携带数据
Bundle bundle=new Bundle();
//传递name参数为tinyphp
bundle.putString("yl2", "我爱你桂霞");
intent.putExtras(bundle);
startActivity(intent);

public class Main2Activity extends AppCompatActivity {

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);
 
    //获取Intent携带数据
    Intent intent = getIntent();
    String index = intent.getStringExtra("yl1");
 
    //用Bundle携带数据
    Bundle bundle = getIntent().getExtras();
    String data = bundle.getString("yl2");//读出数据
 
    Toast.makeText(this, index + "-" + data, Toast.LENGTH_SHORT).show();
}
