Android 在同一活动中的两个GridView之间切换

我一直在寻找如何解决几个问题，并对我的一些问题找到了一些答案，但有一件事仍在建设中，如果你们谁也帮不了我的话，这件事是不会完成的/

我一直在尝试放大和缩小GridView，但考虑到了另一种解决方案，因为我只需要两种状态：概览和详细视图。因此，我做了两个网格视图。第一种方法是收缩两个GridView中的图像，并在不滚动的情况下显示。另一个是图像以其原始大小显示的图像。您可以在其中水平和垂直滚动

我的问题是在这两个GridView之间切换。如果我点击其中一个，我尝试将两者的“可见性”设置为“消失”或“可见”

这是我的密码：

起动器：

package test.scroll;

import android.app.Activity;
import android.os.Bundle;
import android.widget.GridView;
import android.view.View;
import android.view.View.OnClickListener;

public class TestScrollActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

    final GridView grd_overview = (GridView)this.findViewById(R.id.grd_overview);
    grd_overview.setAdapter(new OverviewImageAdapter(this));
    final GridView grd_detailed = (GridView)this.findViewById(R.id.grd_detailed);
    grd_detailed.setVisibility(2);
    grd_detailed.setAdapter(new DetailedImageAdapter(this));

    grd_overview.setOnClickListener(new OnClickListener() {
        public void onClick(View view) {
            grd_overview.setVisibility(2);
            grd_detailed.setVisibility(0);
        }
    });

    grd_detailed.setOnClickListener(new OnClickListener() {
        public void onClick(View view) {
            grd_detailed.setVisibility(2);
            grd_overview.setVisibility(0);
        }
    });
    }
}

概览适配器：

package test.scroll;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;

public class OverviewImageAdapter extends BaseAdapter {  
     private Context mContext;

        public OverviewImageAdapter(Context c) {
            mContext = c;
        }

        public int getCount() {
            return mThumbIds.length;
        }

        public Object getItem(int position) {
            return null;
        }

        public long getItemId(int position) {
            return 0;
        }

        // create a new ImageView for each item referenced by the Adapter
        public View getView(int position, View convertView, ViewGroup parent) {
            ImageView imageView;
            if (convertView == null) {  // if it's not recycled, initialize some attributes
                imageView = new ImageView(mContext);
                imageView.setLayoutParams(new GridView.LayoutParams(82, 82));
                imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            } else {
                imageView = (ImageView) convertView;
            }

            imageView.setImageResource(mThumbIds[position]);
            return imageView;
        }

        // references to our images
        private Integer[] mThumbIds = {
                R.drawable.memory_1, R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,
                R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,
                R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,
                R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,
                R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,
                R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1,R.drawable.memory_1
        };

    }  

详细适配器：

package test.scroll;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;

public class DetailedImageAdapter extends BaseAdapter {  
     private Context mContext;

        public DetailedImageAdapter(Context c) {
            mContext = c;
        }

        public int getCount() {
            return mThumbIds.length;
        }

        public Object getItem(int position) {
            return null;
        }

        public long getItemId(int position) {
            return 0;
        }

        // create a new ImageView for each item referenced by the Adapter
        public View getView(int position, View convertView, ViewGroup parent) {
            ImageView imageView;
            if (convertView == null) {  // if it's not recycled, initialize some attributes
                imageView = new ImageView(mContext);
                imageView.setLayoutParams(new GridView.LayoutParams(82, 82));
            } else {
                imageView = (ImageView) convertView;
            }

            imageView.setImageResource(mThumbIds[position]);
            return imageView;
        }

        // references to our images
        private Integer[] mThumbIds = {
                R.drawable.memory_2, R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,
                R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,
                R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,
                R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,
                R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,
                R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2,R.drawable.memory_2
        };

    }

对于如何在这两个gridview之间切换，您有什么建议吗？让我知道：）

Basti

您应该能够从app_布局中删除您不想看到的网格，并添加您想看到的网格。例如：

RelativeLayout rl = (RelativeLayout) findViewById(R.id.app_layout);
GridView gv = (GridView) findViewById(R.id.grid01); // Replace the ID
GridView gv2 = (GridView) findViewById(R.id.grid02); // Replace too

//...
rl.removeView(gv);
rl.addView(gv2);

// ...
rl.removeView(gv2);
rl.addView(gv);

---

依此类推。

为什么不将两个网格视图都放在一个ViewSwitcher/ViewFlipper中，并以这种方式在它们之间进行翻转呢？

我想你可以很好地实现两个网格之间的切换

从android参考指南：

ViewFlipper是一个简单的ViewAnimator，可以设置动画 在两个或多个具有 已添加到其中。现在只有一个孩子 一次显示一次。如有要求，您可以 在每个子对象之间自动翻转 每隔一段时间

下面介绍如何实现此功能。

下面是演示这一点（用动画）

啊，我不知道我还可以通过父元素隐藏/显示它们：]谢谢！我没想到会有一个浏览者><也谢谢！

RelativeLayout rl = (RelativeLayout) findViewById(R.id.app_layout);
GridView gv = (GridView) findViewById(R.id.grid01); // Replace the ID
GridView gv2 = (GridView) findViewById(R.id.grid02); // Replace too

//...
rl.removeView(gv);
rl.addView(gv2);

// ...
rl.removeView(gv2);
rl.addView(gv);
