保存在RES /布局/ main.xml中的XML文件：我说的对我的main.xml文件worng？我想使用。

XML file saved at res/layout/main.xml:Am i right my main.xml file has worng? I want to use .

   <?xml version="1.0" encoding="utf-8"?>
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView  android:id="@+id/imageView1"
    android:layout_width="wrap_content" android:layout_height="200dp">    </ImageView>
   <TextView android:text="Zoo"
    android:id="@+id/PicDescription" android:layout_width="wrap_content"
    android:textSize="40sp" android:layout_height="wrap_content"
    android:layout_gravity="center" android:layout_marginTop="10dp"></TextView>
  <TextView android:text="Z" android:id="@+id/captitalText"
    android:layout_height="wrap_content" android:layout_gravity="center"    android:textSize="100sp"
    android:layout_width="wrap_content" android:layout_marginTop="25dp"></TextView>

保存在RES /价值/ letters.xml XML文件：

<?xml version="1.0" encoding="utf-8"?>
resources>
  <string-array name="desc">
    <item>Apple</item>
    <item>Ball</item>
    ...
    <item>Zoo</item>
 </string-array>

 <string-array name="capitalLetter">
    <item>A</item>
    <item>B</item>
    ...
    <item>Z</item>
  </string-array>

什么是机器人的水平滚动操作的code。请大家给的意见，我是新android的，我完全糊涂了滚动。我按照这个link1 链接2 ，但不能得到任何想法。在此先感谢，并希望你能解决这个问题。

下面是我的code.It出来的，当我尝试滚动然后改变B，当完成滚动再次成为网页。我想，我打电话的时候滚动完成初始值，对吗？

Here is my code.It out is when I try to scrolling then change B, when complete scrolling the page the again A becomes. I think, I call when scrolling is complete starting value, am i right?

给我建议，我能做些什么的修复此code。

Give me suggestion what can i do for fix this code.

  public class Test extends Activity {
private static final int SWIPE_MIN_DISTANCE = 120;
private static final int SWIPE_MAX_OFF_PATH = 250;
private static final int SWIPE_THRESHOLD_VELOCITY = 200;
private GestureDetector gestureDetector;
String[] big;
TextView txtbig;
int count=0;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    big = getResources().getStringArray(R.array.capitalLetter);

    gestureDetector = new GestureDetector(new MyGestureDetector());
    View mainview = (View) findViewById(R.id.mainView);

    mainview.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            if (gestureDetector.onTouchEvent(event)) {
                textChange();
                return true;
            }
            return false;
        }
    });
    //textChange();
}
private void textChange() {
    txtbig = (TextView) findViewById(R.id.bigText);
    String bigTextString=big[count];
    txtbig.setText(bigTextString);

    count++;

    if(count==big.length)
    {
    count=0;
    }
}
class MyGestureDetector extends SimpleOnGestureListener {
    @Override

    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {

        Intent intent = new Intent(Test.this.getBaseContext(),Test.class);
         //textChange();
        if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) {
            //textChange();
            return false;
        }

        // right to left swipe
        if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {                textChange();
            startActivity(intent);
            Test.this.overridePendingTransition(
                    R.anim.slide_in_right, R.anim.slide_out_left);

            return true;
            // right to left swipe
        } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
            // startActivity(intent);
            // textChange();
            Test.this.overridePendingTransition(
                    R.anim.slide_in_left, R.anim.slide_out_right);
        }

        return false;
    }
    @Override
    public boolean onDown(MotionEvent e) {
        return true;
    }
}

}
