在MainActivity里

public class MainActivity extends Activity {    private EditText et_name;private EditText et_content;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                et_name = (EditText) findViewById(R.id.et_name);        et_content = (EditText) findViewById(R.id.et_content);    }        public void go(View v){    String name = et_name.getText().toString();    String content = et_content.getText().toString();        //Intent 和Request的机制一样    Intent intent = new Intent(this,OtherActivity.class);/*    intent.putExtra("name", name);    intent.putExtra("content", content);*/        Bundle bundle = new Bundle();//类似一个Map    bundle.putString("name", name);    bundle.putString("content", content);    intent.putExtras(bundle);            startActivity(intent);    }}

在OtherActivity里

public class OtherActivity extends Activity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.other);                //获取Intent        Intent intent = getIntent();/*        String name = intent.getStringExtra("name");        String content = intent.getStringExtra("content");*/        //使用上面的步骤也可以取出值，只是分开取，bundle的底层原理其实是map集合的原理        Bundle bundle = intent.getExtras();        String name = bundle.getString("name");        String content = bundle.getString("content");                TextView tv_info = (TextView) findViewById(R.id.tv_info);        tv_info.setText(name+content);            }}
