用GirdView，设置成3列显示public class MainActivity extends Activity {
 
    private GridView gridView;
    private gridItemAdapter mAdapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);        
        setContentView(R.layout.mainlayout);
        gridView = (GridView)findViewById(R.id.grid1);
        mAdapter = new gridItemAdapter(this);
        gridView.setAdapter(mAdapter);
       
    }    private class gridItemAdapter extends BaseAdapter
    {
        private Integer[] numbers = {1,2,3,4,5,6,7,8,9};
        private Context mcontext;
        public gridItemAdapter(Context context)
        {
            mcontext = context;
        }
        @Override
        public int getCount() {
            return numbers.length;
        }        @Override
        public Object getItem(int position) {
            return numbers[position];
        }        @Override
        public long getItemId(int position) {
            return 0;
        }        @Override
        public View getView(final int position, View view, ViewGroup parent) {
            if (view == null)
            {
                Button btnnumber = new Button(mcontext);
                LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
                btnnumber.setLayoutParams(lp);
                btnnumber.setText(String.valueOf(numbers[position]));
                btnnumber.setTag(numbers[position]);
                btnnumber.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Toast.makeText(mcontext,String.valueOf(numbers[position]),Toast.LENGTH_SHORT).show();
                    }
                });
                view = btnnumber;
            }
           
            return view;
        }
    }
}

Answer 7

你的GridView上级是嵌套的RelativeLayout，所以在代码里也得用RelativeLayout.LayoutParams
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
换成
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

Answer 8

GridView即可，是在不行就用weight
