动态添加按钮到TableRow

Question

您好我想单击一个按钮,每次单击它时都会向表行添加一个新按钮.在向行添加了3个按钮后,我想动态创建一个新的表行并向其添加一个新按钮.

我知道如果单击一个按钮,如何将一个按钮添加到tableLayout.我不知道每次点击时如何修改表格行,所以我可以添加一个额外的按钮.

任何建议都会非常有帮助和赞赏.

以下是我的代码,但这并不完美

public class DynamicTableView extends Activity {

    TableLayout mTlayout;
    String[] mTextofButton = { "Dipak", "E", "I", "J", "L",
            "M", "G", "R", "N", "T", "H", "P",
            "K", "Y", "V" };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mTlayout = (TableLayout) findViewById(R.id.mTlayout);


        TableRow tr=new TableRow(this);
        for(int i=0;i<mTextofButton.length;i++){
            Button btn=new Button(this);
            btn.setText(mTextofButton[i]);
            tr.addView(btn);

        }   
        mTlayout.addView(tr);
    }
}

提前致谢.

使用以下代码: -

public class DynamicButtonsActivity extends Activity {

    TableLayout mTlayout;
    TableRow tr;
    String[] mTextofButton = { "D", "E", "I", "J", "L", "M", "G", "R", "N",
            "T", "H", "P", "K", "Y", "V" };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mTlayout = (TableLayout) findViewById(R.id.mTlayout);

        int i = 0;
        while (i < mTextofButton.length) {
            if (i % 3 == 0) {
                tr = new TableRow(this);
                mTlayout.addView(tr);
            }
            Button btn = new Button(this);
            btn.setText(mTextofButton[i]);
            btn.setId(i);
            btn.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    System.out.println("v.getid is:- " + v.getId());
                }
            });
            tr.addView(btn);
            i++;
        }
    }
}
