【簡單的學生管理界面】Android的Activity與Activity之間如何傳值

用Intent傳值

父Activity（這裏給出onCreate的代碼）：

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		TextView i = (TextView)findViewById(R.id.i);
		i.setText("0005550000");//這是將要傳到子Activity的值
		
		Intent intent = new Intent(MainActivity.this,SubActivity.class);
		intent.putExtra("father", i.getText().toString());
		startActivity(intent);//跳轉到子Activity
	}

	

子Activity：

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_sub);

		TextView j = (TextView)findViewById(R.id.j);
		
		Intent getIntent = getIntent();
		String ll = getIntent.getStringExtra("father");//獲取父Activity傳過來的值
		j.setText(ll);//在界面中顯示
	}

效果圖如下：
