我正在开发一个Android应用程序，需要一个“Card Deck” UI小部件。
这是一个关于如何实现以下功能的活动/布局示例请求：
1) 竖向滑动支持:
列出一副可以垂直滚动/滑动的牌组。StackView 可以做到这一点，但我也可以接受任何其他行之有效的解决方案（例如，一些 CardUI 项目）
2) 横向滑动支持:
对于任何一张卡片，都有两个词典定义：
示例:
[A1][Card1][B1]
[A2][Card2][B2]
[A3][Card3][B3]
我确实看到这篇相关的帖子，那里的答案提供了一些提示和参考信息...但不幸的是，我仍在努力弄清楚。
CardDeck：Android上的纸牌堆
DeckPicker：一个完整的Android Anki Droid项目，具有一些额外功能，包括浏览器屏幕内的卡片预览。在预览屏幕上，卡片将显示为卡片浏览器窗口上的复习模式。
activity_fullscreen_view.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
还有一个全屏查看器的Java类
public class FullScreenImageAdapter extends PagerAdapter {
private Activity _activity;
private ArrayList<String> _imagePaths;
private LayoutInflater inflater;
// constructor
public FullScreenImageAdapter(Activity activity,
ArrayList<String> imagePaths) {
this._activity = activity;
this._imagePaths = imagePaths;
}
@Override
public int getCount() {
return this._imagePaths.size();
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == ((RelativeLayout) object);
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
ImageView imgDisplay;
Button btnClose;
inflater = (LayoutInflater) _activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View viewLayout = inflater.inflate(R.layout.layout_fullscreen_image, container,
false);
imgDisplay = (ImageView) viewLayout.findViewById(R.id.imgDisplay);
btnClose = (Button) viewLayout.findViewById(R.id.btnClose);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(_imagePaths.get(position), options);
imgDisplay.setImageBitmap(bitmap);
// close button click event
btnClose.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
_activity.finish();
}
});
((ViewPager) container).addView(viewLayout);
return viewLayout;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((RelativeLayout) object);
}
}
要添加垂直运动，只需包含附加的垂直布局即可。main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Swipe Demo"
android:gravity="center"
android:layout_margin="10dip" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:gravity="center">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:layout_margin="10dip"
android:id="@+id/image_place_holder"/>
</LinearLayout>
</LinearLayout>
这将允许您垂直地滑动物品：
在一天结束时，你希望拥有的是一个网格，例如垂直和水平滚动。为此，您必须将垂直和水平滑动结合到 表格布局中：
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent">
<TableLayout
android:id="@+id/amortization"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TableRow
android:background="#ffff00">
<TextView
android:text="@string/amortization_1"
android:padding="3dip"/>
<TextView
android:text="@string/amortization_2"
android:padding="3dip"/>
<TextView
android:text="@string/amortization_3"
android:padding="3dip"/>
<TextView
android:text="@string/amortization_4"
android:padding="3dip"/>
<TextView
android:text="@string/amortization_5"
android:padding="3dip"/>
<TextView
android:text="@string/amortization_6"
android:padding="3dip"/>
<TextView
android:text="@string/amortization_7"
android:padding="3dip"/>
</TableRow>
</TableLayout>
</HorizontalScrollView>
</ScrollView>
请尝试这个示例代码 -
public class Main extends Activity {
int position=0;
LinearLayout full;
Intent intent;
public Integer[] images= {
R.drawable.image1, R.drawable.image2,
R.drawable.image3, R.drawable.image4,
R.drawable.image5, R.drawable.image6
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
full = (LinearLayout) findViewById(R.id.full);
changeImage();
ActivitySwipeDetector activitySwipeDetector = new ActivitySwipeDetector(this);
full.setOnTouchListener(activitySwipeDetector);
}
private void changeImage(){
full.setBackgroundResource(images[position]);
}
public class ActivitySwipeDetector implements View.OnTouchListener {
static final String logTag = "ActivitySwipeDetector";
static final int MIN_DISTANCE = 100;
private float downX, upX;
Activity activity;
public ActivitySwipeDetector(Activity activity){
this.activity = activity;
}
public void onRightToLeftSwipe(){
Log.i(logTag, "RightToLeftSwipe!");
if(position < images.length - 1){
position++;
changeImage();
}
}
public void onLeftToRightSwipe(){
Log.i(logTag, "LeftToRightSwipe!");
if(position > 0){
position--;
changeImage();
}
}
public boolean onTouch(View v, MotionEvent event) {
switch(event.getAction()){
case MotionEvent.ACTION_DOWN: {
downX = event.getX();
return true;
}
case MotionEvent.ACTION_UP: {
upX = event.getX();
float deltaX = downX - upX;
// swipe horizontal?
if(Math.abs(deltaX) > MIN_DISTANCE){
// left or right
if(deltaX < 0) { this.onLeftToRightSwipe(); return true; }
if(deltaX > 0) { this.onRightToLeftSwipe(); return true; }
}
else {
Log.i(logTag, "Swipe was only " + Math.abs(deltaX) + " long, need at least " + MIN_DISTANCE);
return false; // We don't consume the event
}
return true;
}
}
return false;
}
}
@Override
protected void onPause() {
super.onPause();
}
@Override
public void onResume()
{
super.onResume();
}
@Override
protected void onStop() {
super.onStop();
}
@Override
public void onBackPressed() {
super.onBackPressed();
}
}
