android studio参数传递实验,Android Studio开发基础之Activity之间参数传递

一、简单数值传递

1、MainActivity

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

//startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.baidu.com")));

Intent i=new Intent(MainActivity.this,NewActivity.class);

i.putExtra("data","我是要传递的字符串");

startActivity(i);

}

});

}

2、NewActivity

private TextView T;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_new);

Intent i=getIntent();

T=(TextView) findViewById(R.i
