android gridview不顯示全屏？

Question

我正在做一個應用程序，我在滾動視圖中使用網格視圖。我已經實現了動態。，但問題是我的網格視圖在滾動視圖中顯示不正確。我想表明它全屏幕上，我do..please幫我，這裏是我的代碼

public class MainActivity extends Activity { 
// RelativeLayout rl; 
GridView grid; 
List<String> list; 
Button button1; 
ArrayAdapter<String> adp; 
ImageView image_view; 
boolean isList = false; 
LinearLayout l1; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    //rl=(RelativeLayout) findViewById(R.id.rl); 
    l1 = (LinearLayout)findViewById(R.id.l1); 

    LayoutInflater inflater = LayoutInflater.from(MainActivity.this); 



    LinearLayout layout = (LinearLayout) inflater.inflate(R.layout.header, null, false); 
    image_view = (ImageView) layout.findViewById(R.id.image_view); 
    l1.addView(layout); 


    grid =new GridView(MainActivity.this); 
    list=new ArrayList<String>(); 

    list.add("Dynamic 1"); 
    list.add("Dynamic 2"); 
    list.add("Dynamic 3"); 
    list.add("Dynamic 4"); 
    list.add("Dynamic 5"); 
    list.add("Dynamic 6"); 
    list.add("Dynamic 7"); 
    list.add("Dynamic 8"); 
    list.add("Dynamic 9"); 
    list.add("Dynamic 1"); 
    list.add("Dynamic 2"); 
    list.add("Dynamic 3"); 
    list.add("Dynamic 4"); 
    list.add("Dynamic 5"); 
    list.add("Dynamic 6"); 
    list.add("Dynamic 7"); 
    list.add("Dynamic 8"); 
    list.add("Dynamic 9"); 
    list.add("Dynamic 1"); 
    list.add("Dynamic 2"); 
    list.add("Dynamic 3"); 
    list.add("Dynamic 4"); 
    list.add("Dynamic 5"); 
    list.add("Dynamic 6"); 
    list.add("Dynamic 7"); 
    list.add("Dynamic 8"); 
    list.add("Dynamic 9"); 
    list.add("Dynamic 1"); 
    list.add("Dynamic 2"); 
    list.add("Dynamic 3"); 
    list.add("Dynamic 4"); 
    list.add("Dynamic 5"); 
    list.add("Dynamic 6"); 
    list.add("Dynamic 7"); 
    list.add("Dynamic 8"); 
    list.add("Dynamic 9"); 


    adp =new ArrayAdapter<String> (this, 
      android.R.layout.simple_dropdown_item_1line,list); 
    grid.setNumColumns(2); 
    grid.setStretchMode(GridView.STRETCH_COLUMN_WIDTH); 

    grid.setAdapter(adp); 
    //lL.addView(grid); 
    isList = false; 
    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT); 
    grid.setLayoutParams(lp); 

    l1.addView(grid); 

    image_view.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      if(!isList){ 
       isList = true; 
       grid.setNumColumns(1); 
      } 
      else if(isList) 
      { 
       isList = false; 
       grid.setNumColumns(2); 
      } 
     } 
    }); 

    grid.setOnItemClickListener(new OnItemClickListener() { 


     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
       long arg3) { 

      Toast.makeText(getBaseContext(), list.get(arg2), 
        Toast.LENGTH_SHORT).show(); 
     } 
    }); 

    /*grid.setOnTouchListener(new OnTouchListener(){ 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      if(event.getAction() == MotionEvent.ACTION_MOVE){ 
       return true; 
      } 
      return false; 
     } 

    });*/ 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

    } 

這裏適配器類

public class healperadapter { 
public static void getListViewSize(ListView myListView) { 
    ListAdapter myListAdapter = myListView.getAdapter(); 
    if (myListAdapter == null) { 
     //do nothing return null 
     return; 
    } 
    //set listAdapter in loop for getting final size 
    int totalHeight = 0; 
    for (int size = 0; size < myListAdapter.getCount(); size++) { 
     View listItem = myListAdapter.getView(size, null, myListView); 
     listItem.measure(0, 0); 
     totalHeight += listItem.getMeasuredHeight(); 
    } 
    //setting listview item in adapter 
    ViewGroup.LayoutParams params = myListView.getLayoutParams(); 
    params.height = totalHeight + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1)); 
    myListView.setLayoutParams(params); 
    // print height of adapter on log 

} 


public static void getGridViewSize(GridView grid) { 
    ArrayAdapter<String> myListAdapter = (ArrayAdapter<String>) grid.getAdapter(); 
    if (myListAdapter == null) { 
     //do nothing return null 
     return; 
    } 
    //set listAdapter in loop for getting final size 
    int totalHeight = 0; 
    for (int size = 0; size < myListAdapter.getCount(); size++) { 
     View listItem = myListAdapter.getView(size, null, grid); 
     listItem.measure(0, 0); 
     totalHeight += listItem.getMeasuredHeight(); 
    } 
    //setting listview item in adapter 
    ViewGroup.LayoutParams params = grid.getLayoutParams(); 
    params.height = totalHeight + (grid.getHeight() * (myListAdapter.getCount() - 1)); 
    grid.setLayoutParams(params); 
    // print height of adapter on log 

} 
    } 

這裏是XML類

<FrameLayout 
    android:id="@+id/frameLayout1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentTop="true" > 

    <TextView 
     android:id="@+id/textView1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="TextView" /> 
</FrameLayout> 

<ScrollView 
    android:id="@+id/scrollView1" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_below="@+id/frameLayout1" > 

    <LinearLayout 
     android:id="@+id/l1" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical" > 
    </LinearLayout> 
</ScrollView> 

</RelativeLayout> 

，這是事先header.xml

<RelativeLayout 
    android:id="@+id/category_layout" 
    android:layout_width="fill_parent" 
    android:layout_height="41dp" 
    android:layout_marginTop="5dp" > 

    <ImageView 
     android:id="@+id/image_view" 
     android:layout_width="25dp" 
     android:layout_height="25dp" 
     android:layout_alignParentRight="true" 
     android:layout_centerVertical="true" 
     android:layout_margin="3dp" 
     android:background="@drawable/ic_launcher" 
     android:visibility="visible" /> 

    <TextView 
     android:id="@+id/Itemfound" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_centerVertical="true" 
     android:layout_marginLeft="10dp" 
     android:layout_marginRight="5dp" 
     android:layout_toLeftOf="@+id/view1" 
     android:singleLine="true" 
     android:textColor="#FFFFFF" 
     android:textSize="13sp" /> 

    <View 
     android:id="@+id/view1" 
     android:layout_width="1dp" 
     android:layout_height="fill_parent" 
     android:layout_margin="2dp" 
     android:layout_toLeftOf="@+id/image_view" 
     android:background="#009900" /> 
</RelativeLayout> 

<View 
    android:layout_width="fill_parent" 
    android:layout_height="1dp" 
    android:background="#009900" > 
</View> 

</LinearLayout> 

感謝.... :)

Answer 1

嘗試用下面的網格視圖。

public class ExpandableHeightGridView extends GridView { 

    boolean expanded = false; 

    public ExpandableHeightGridView(Context context) { 
     super(context); 
    } 

    public ExpandableHeightGridView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
    } 

    public ExpandableHeightGridView(Context context, AttributeSet attrs, 
      int defaultStyle) { 
     super(context, attrs, defaultStyle); 
    } 

    public boolean isExpanded() { 
     return expanded; 
    } 

    public void setExpanded(boolean expanded) { 
     this.expanded = expanded; 
    } 

    @Override 
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     if (isExpanded()) { 
      int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK, 
        MeasureSpec.AT_MOST); 
      super.onMeasure(widthMeasureSpec, expandSpec); 

      ViewGroup.LayoutParams params = getLayoutParams(); 
      params.height = getMeasuredHeight(); 
     } else { 
      super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
     } 
    } 
} 

後設置您在GridView中寫gridview.isExpanded(true);
