标签： java android android-fragments gridview

我有一个片段MobilesFragment，我想在其中显示一个gridview，它将包含两个textview和一个imageview，但在我第一次运行时，th是一个正在发生的异常，

我的gridview布局文件：

<?xml version="1.0" encoding="utf-8"?>
<GridView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/dataGrid"
    android:numColumns="2"
    android:layout_gravity="center_horizontal" >
</GridView>

这是我的Fragment类：

package com.ui.fragments;

import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.drawable.Drawable;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.GridView;

import com.data.dataclass.GridViewData;
import com.devs.fookart.GridViewAdapter;
import com.devs.fookart.R;

import java.util.ArrayList;


public class MobilesFragment extends Fragment
{   private GridViewAdapter adapter;
private GridView mList;
private Context context;
private ArrayList<GridViewData> gridItems;
private String titles[]={"Headphones","Camera","Home","Mobile"};
private int prices[]={100,122,212,122};
private ArrayList<Bitmap> bmp;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
{   View rootView=inflater.inflate(R.layout.fragment_mobiles,container,false);
    context=container.getContext();
    bmp=new ArrayList<Bitmap>();
    bmp.add(BitmapFactory.decodeResource(context.getResources(),R.mipmap.ic_headphones));
    bmp.add(BitmapFactory.decodeResource(context.getResources(),R.mipmap.ic_camera));
    bmp.add(BitmapFactory.decodeResource(context.getResources(),R.mipmap.ic_home));
    bmp.add(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_mobile));
    gridItems=new ArrayList<GridViewData>();
    mList=(GridView)rootView.findViewById(R.id.dataGrid);
    gridItems.add(new GridViewData(1,titles[0],bmp.get(2),prices[0]));
    gridItems.add(new GridViewData(2,titles[1],bmp.get(2),prices[1]));
    gridItems.add(new GridViewData(3,titles[2],bmp.get(3),prices[2]));
    gridItems.add(new GridViewData(4,titles[3],bmp.get(2),prices[3]));

    adapter=new GridViewAdapter(context,gridItems);
    mList.setAdapter(adapter);
    return rootView;
}
}

GridItem布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:weightSum="1">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:text="Title"
    android:id="@+id/title"
    android:layout_weight="0.02" />

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/product"
    android:layout_weight="0.36"
    android:src="@mipmap/ic_launcher" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:text="Price"
    android:id="@+id/price"
    android:layout_weight="0.02" />
</LinearLayout>

GridViewData类：

package com.data.dataclass;

import android.graphics.Bitmap;

public class GridViewData
{   private String name;
private int price,id;
private Bitmap image;

public GridViewData(int id,String name,Bitmap image,int price)
{   this.name=name;
    this.image=image;
    this.price=price;
    this.id=id;
}

public int getId()
{   return id;
}

public void setId(int id)
{   this.id = id;
}

public String getName()
{   return name;
}

public void setName(String name)
{   this.name=name;
}

public int getPrice()
{   return price;
}

public void setPrice(int price)
{   this.price=price;
}

public Bitmap getImage()
{   return image;
}

public void setImage(Bitmap image)
{   this.image=image;
}
}

最后一个GridView Adapter类：

package com.devs.fookart;

import android.app.Activity;
import android.content.Context;
import android.widget.TextView;
import android.widget.ImageView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;

import com.data.dataclass.GridViewData;

import java.util.ArrayList;

public class GridViewAdapter extends BaseAdapter
{   private ArrayList<GridViewData> GridItem;
private Context context;

public GridViewAdapter(Context context,ArrayList<GridViewData> GridItem)
{   this.context=context;
    this.GridItem=GridItem;
}

@Override
public int getCount()
{   return GridItem.size();
}

@Override
public Object getItem(int position)
{   return GridItem.get(position);
}

@Override
public long getItemId(int position)
{   return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent)
{   if(convertView==null)
    {   LayoutInflater mInflater=(LayoutInflater)context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView=mInflater.inflate(R.layout.product_grid,null);;
    }
    ImageView img=(ImageView)convertView.findViewById(R.id.product);
    TextView title=(TextView)convertView.findViewById(R.id.title);
    TextView price=(TextView)convertView.findViewById(R.id.price);
    img.setImageBitmap(GridItem.get(position).getImage());
    title.setText(GridItem.get(position).getName());
    price.setText(GridItem.get(position).getPrice());
    return convertView;
}
}

这将是一个巨大的帮助，非常感谢提前......

答案 0 :(得分：0)

看起来getPrice()正在返回int并且您将它传递给setText（），这可能会导致此问题，因为此整数被解释为{{1}中某些字符串的资源标识符像strings.xml一样。

改变这个：

R.string.hello_world

到此：

price.setText(GridItem.get(position).getPrice());

请告诉我这是否有帮助：）
