android工作室中的網格

Question

有人可以告訴我如何在android studio上創建一個帶黑色邊框的空網格？

它應該允許網格內的小部件。

我試過了，但結果與我的預期不同。

在這段代碼中，你可以通過使用電網layout..Try這個代碼放置任何插件...

// XML：

<?xml version="1.0" encoding="utf-8"?> 
<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/gridview" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:columnWidth="90dp" 
    android:numColumns="auto_fit" 
    android:verticalSpacing="10dp" 
    android:horizontalSpacing="10dp" 
    android:stretchMode="columnWidth" 
    android:gravity="center" 
/> 

//Sample.java

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.GridView; 


public class Sample extends Activity { 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_sample); 
    GridView gridview = (GridView) findViewById(R.id.gridview); 
    gridview.setAdapter(new ImageAdapter(Sample.this)); 
} 
} 

//ImageAdapter.java

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 ImageAdapter extends BaseAdapter { 
    private Context mContext; 

// Constructor 
public ImageAdapter(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) { 
     imageView = new ImageView(mContext); 
     imageView.setLayoutParams(new GridView.LayoutParams(170, 170)); 

     imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 

    } else { 
     imageView = (ImageView) convertView; 
    } 
    imageView.setImageResource(mThumbIds[position]); 
    return imageView; 
} 

// Keep all Images in array 
public Integer[] mThumbIds = { 
//here you can place the image 
    R.drawable.ic_radio_2, R.drawable.ic_radio_3, 
    R.drawable.ic_radio_4, R.drawable.ic_radio_5, 
    R.drawable.ic_radio_4, R.drawable.ic_radio_6, 

}; 
}
