java view要素の部分更新

Question

複数あるviewのうち、一部のviewのみ更新を行いたいのですが、
setLayoutParamsで更新をおこなってしまうとview全てが更新されてしまいます。
一部だけ更新する場合、どのような方法が良いのでしょうか。

初期配置
al.addView(cards.get(i), new AbsoluteLayout.LayoutParams(
change_dptopx(Card.width),
change_dptopx(Card.height),
width / 10 + change_dptopx(30),
(3 * height / 8) + change_dptopx(Card.height) * 2 / 5
- change_dptopx(30)));

al.addView(cards.get(i), new AbsoluteLayout.LayoutParams(
change_dptopx(Card.width),
change_dptopx(Card.height), width / 10
+ change_dptopx(30), (4 * height / 8)
+ change_dptopx(Card.height) * 2 / 5
- change_dptopx(30)));

al.addView(cards.get(i), new AbsoluteLayout.LayoutParams(
change_dptopx(Card.width),
change_dptopx(Card.height), width / 10
+ change_dptopx(30), (5 * height / 8)
+ change_dptopx(Card.height) * 2 / 5
- change_dptopx(30)));

viewのサイズ変更

public void fixcard() {

		  if (centerX > 4*app.screen_size_width / 7 + Card.width / 5
					&& centerX < 4*app.screen_size_width / 7 + Card.width
							- Card.width / 5
					&& centerY > ( 1+2) * app.screen_size_height / 8
							+ change_dptopx(Card.height) * 2 / 5
							- change_dptopx(30)
					&& centerY < (1+2) * app.screen_size_height / 8
							+ change_dptopx(Card.height) * 2 / 5 + Card.height
							- change_dptopx(30)) {





				  if (main.settable(1)) {
					  Log.d("cardset", "????="+change_dptopx(Card.width));
					  Log.d("cardset", "width="+width);



					  this.setLayoutParams(new AbsoluteLayout.LayoutParams(
								80,
								43,
								4*1280/7+150,
								272));

main.card_set(1, this);
Log.v("set", "space=" + 1);
}
}

	else if (centerX > 4*app.screen_size_width / 7 + Card.width / 5
					&& centerX < 4*app.screen_size_width / 7 + Card.width
							- Card.width / 5
					&& centerY > ( 2+2) * app.screen_size_height / 8
							+ change_dptopx(Card.height) * 2 / 5
							- change_dptopx(30)
					&& centerY < (2+2) * app.screen_size_height / 8
							+ change_dptopx(Card.height) * 2 / 5 + Card.height
							- change_dptopx(30)) {


				  if (main.settable(2)) {
					  Log.d("cardset", "????="+change_dptopx(Card.width));
					  Log.d("cardset", "width="+width);

					  Log.d("cardset", "width2="+width);

					  this.setLayoutParams(new AbsoluteLayout.LayoutParams(
								160,
								85,
								4*1280/7,
								390));

main.card_set(2, this);
Log.v("cardset", "width2="+width);
Log.v("set", "space=" + 2);

				  }

		  }


	else if(centerX > 4*app.screen_size_width / 7 + Card.width / 5
				&& centerX < 4*app.screen_size_width / 7 + Card.width
						- Card.width / 5
				&& centerY > ( 3+2) * app.screen_size_height / 8
						+ change_dptopx(Card.height) * 2 / 5
						- change_dptopx(30)
				&& centerY < (3+2) * app.screen_size_height / 8
						+ change_dptopx(Card.height) * 2 / 5 + Card.height
						- change_dptopx(30)) {


			  if (main.settable(3)) {
				  Log.d("cardset", "????="+change_dptopx(Card.width));
				  Log.d("cardset", "width="+width);

this.setLayoutParams(new AbsoluteLayout.LayoutParams(
480,
85,
4*1280/7,
510));

				main.card_set(3, this);
				Log.v("set", "space=" + 3);
			  }


	 }

JavaのGUIにはAndroid以外にもJavaFX, swing, processingなど異なるものがあるので、質問のタグにAndroidを追加しておく方がよいでしょう。

コードの例示がなければさっぱりわかりません。
