putExtra参数详解
public class MyIntent extends Activity {
/*声明控件对象*/
private EditText et1, et2;
private Button bt;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/*取得控件对象*/
et1 = (EditText) findViewById(R.id.et1);
et2 = (EditText) findViewById(R.id.et2);
bt = (Button) findViewById(R.id.bt);
/*为按钮绑定监听器*/
bt.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
/*取得输入框中的内容*/
String et1Str = et1.getText().toString();
String et2Str = et2.getText().toString();
//创建Intent对象，参数分别为上下文，要跳转的Activity类
Intent intent = new Intent(MyIntent.this, SecondActivity.class);
//将要传递的值附加到Intent对象
intent.putExtra("et1", et1Str);
intent.putExtra("et2", et2Str);
//启动该Intent对象，实现跳转
startActivity(intent);
}
});
}
