动态加载布局

效果：通过浮动的方式来展示原图。

步骤：1、动态创建一个ImageView加入到游戏界面中。并将它的Visibility设置为View.GONE 当点击显示按钮时，将原图显示出来。

以一个动画的形式显示出来，或者隐藏。

code

1.

//添加显示原图的View

private void addImageView() {

RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.handle_parents);

imageView = new ImageView(PuzzleActivity.this);

imageView.setImageBitmap(changeLaterBitmap);

int x = changeLaterBitmap.getWidth();
int y = changeLaterBitmap.getHeight();
ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(x, y);
imageView.setLayoutParams(params);
relativeLayout.addView(imageView);
imageView.setVisibility(View.GONE);
}

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/handle_parents">

<LinearLayout
.......

private View.OnClickListener buttonListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
switch (v.getId()) {
//恢复原图
case R.id.resume:

Animation animationShow =
AnimationUtils.loadAnimation(PuzzleActivity.this, R.anim.anim);
Animation animationMiss =
AnimationUtils.loadAnimation(PuzzleActivity.this, R.anim.missanim);

if (mIsShowing) {
imageView.startAnimation(animationMiss);
imageView.setVisibility(View.GONE);
mIsShowing = false;

} else {

imageView.startAnimation(animationShow);
imageView.setVisibility(View.VISIBLE);
mIsShowing = true;
}

break;

xml定义动画

隐藏动画

"><?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate
android:duration="1000"
android:fromYDelta="0%"
android:toYDelta="-200%" />

</set>

1. 显示动画

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate
android:duration="1000"
android:fromYDelta="-200%"
android:toYDelta="0%" />

</set>
