android studio gridview如何实现

我实现的老是黑屏退出
mainactivity.java

 private LayoutInflater inflater;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main); 

        inflater = LayoutInflater.from(getApplicationContext());                
        GridView dev_listview =(GridView)findViewById(R.id.dev_listview);
        MyAdapter gAdapter = new MyAdapter (this);          
        dev_listview.setAdapter(gAdapter);
        setContentView(R.id.dev_listview);
    }

MyAdapter.java

 public class MyAdapter extends BaseAdapter {
      private LayoutInflater inflater;
    private Context mcontext;
    private Integer[] mThumbnails = {R.drawable.unpress9};
    public MyAdapter( Context c) 
    { 
       mcontext = c;
    } 
     public int getCount() {
            return mThumbnails.length;
     }
     public Object getItem(int position) {
            return null;
        }

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


      @SuppressLint("InflateParams")
    public View getView(int position, View grid, ViewGroup parent) 
      {
          inflater = (LayoutInflater)mcontext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    if(grid != null)
     {
        inflater = LayoutInflater.from(mcontext);
        grid =inflater.inflate(R.layout.item_9,parent);
     }

     return grid;

     }

}

                <ImageView
                    android:id="@+id/qry"/>
            </LinearLayout>

        </LinearLayout>

    </LinearLayout>

</LinearLayout>

想实现的功能是:item.xml全部写进gridview的一个item中,这个item里有9行,我下个item调用令一个5行的item5.xml,要保障不同item每行的高度都一样,如何实现呢,求大神指教!
