Android应用TranslateAnimation移动之后，利用视图的setLayoutParams从新定位

Android中利用TranslateAnimation移动时，不设置mTranslateAnimation.setFillAfter(true);，而利用视图的setLayoutParams来重新定位。。。。因为mTranslateAnimation.setFillAfter(true);之后，视图的事件消失，并且还有很多其他的问题。

 

而我们采用Animation.AnimationListener，在onAnimationEnd的方法中改变当前视图利用LayoutParams的setMargins方法重新定位位置。

 

 

代码段，仅供参考。

public void move() {
		jqkjScroll.setEnabled(true);
		Animation mTranslateAnimation = new TranslateAnimation(0, 0, 0,
				-showheight);// 移动

		mTranslateAnimation.setDuration(minute);
		// mAnimationSet.setFillAfter(true);
		// mTranslateAnimation.setFillAfter(true);
		mTranslateAnimation
				.setAnimationListener(new Animation.AnimationListener() {
					public void onAnimationStart(Animation animation) {
						if (isNoMenu == false) {
							curent.setVisibility(View.GONE);
						}
					}

					public void onAnimationEnd(Animation animation) {
						RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
								contentLayout.getLayoutParams());
						contentImg.setImageResource(R.drawable.open);
						params.setMargins(0, endY - startY, 0, 0);
						contentLayout.clearAnimation();
						contentLayout.setLayoutParams(params);
						jqkjScroll.scrollTo(0, 0);
						isMoveORShowing = false;
					}

					public void onAnimationRepeat(Animation animation) {

					}
				});
		contentLayout.startAnimation(mTranslateAnimation);

	}

	public void show() {
		jqkjScroll.setEnabled(false);
		Animation mTranslateAnimation = new TranslateAnimation(0, 0, 0,
				showheight);// 移动
		mTranslateAnimation.setDuration(minute);
		mTranslateAnimation
				.setAnimationListener(new Animation.AnimationListener() {
					public void onAnimationStart(Animation animation) {
						if (isNoMenu == false) {
							curent.setVisibility(View.VISIBLE);
						}
					}

					public void onAnimationEnd(Animation animation) {
						contentImg.setImageResource(R.drawable.close);
						isMoveORShowing = false;
						contentLayout.clearAnimation();
						RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
								contentLayout.getLayoutParams());
						params.setMargins(0, showheight + endY - startY, 0, 0);

						contentLayout.setLayoutParams(params);
					}

					public void onAnimationRepeat(Animation animation) {

					}
				});
		contentLayout.startAnimation(mTranslateAnimation);
	}
