android - 在 Android 中一次滑动即可将图库 View 移动到下一张图片？

Question

画廊 View 中有四张图片。当我们从左向右或从右向左滑动时，画廊 View 会移动所有图像，即如果我从第一张图像从左向右滑动，那么它将移动到所有四张图像。我想要的是，当我滑动时，它应该只移动到下一张图片。谁能告诉我这在 galleryview 中如何实现？

我认为您必须使用手势才能通过手指滑动来更改图像。为此，下面的代码可能对您有所帮助。

import java.util.ArrayList;import android.app.Activity;import android.gesture.Gesture;import android.gesture.GestureLibraries;import android.gesture.GestureLibrary;import android.gesture.GestureOverlayView;import android.gesture.Prediction;import android.gesture.GestureOverlayView.OnGesturePerformedListener;import android.os.Bundle;import android.widget.Toast;
public class GesturesActivity extends Activity implements OnGesturePerformedListener {    private GestureLibrary mLibrary;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mLibrary = GestureLibraries.fromRawResource(this, R.raw.spells);
    if (!mLibrary.load()) {
        finish();
    }

    GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures);
    gestures.addOnGesturePerformedListener(this);
}

public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
    ArrayList<Prediction> predictions = mLibrary.recognize(gesture);

    // We want at least one prediction
    if (predictions.size() > 0) {
        Prediction prediction = predictions.get(0);
        // We want at least some confidence in the result
        if (prediction.score > 1.0) {
            // Show the spell
            Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT).show();
        }
    }
}
在这里输入代码
