安卓學習筆記（三）、使用Intent傳遞數據

1、

public class MainActivity extends Activity {
	private Button button;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);//加載佈局文件
        button = (Button) this.findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
			Intent intent = new Intent(MainActivity.this,OtherActivity.class);
			intent.putExtra("name", "小哥");
			intent.putExtra("age", 23);
			intent.putExtra("address", "杭州");
			startActivity(intent);
			}
		});
    }
}

2、

public class OtherActivity extends Activity {
	private TextView textView;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.other);
		textView = (TextView) this.findViewById(R.id.msg);
		Intent intent = getIntent();
		int age = intent.getIntExtra("age", 0);
		String name = intent.getStringExtra("name");
		String address = intent.getStringExtra("address");
		
		textView.setText("age---->>"+age+"\n"+"name--->>"+name+"\n"+address);
	}

}
