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
