android - 在 Android 中单击按钮时向布局添加新 View

Question

我正在为纸牌游戏“黑桃”开发记分应用程序。

在每手牌结束时单击按钮，我想将有关这手牌的一些信息存储到 TextView 中，并在 ScrollView 中显示所有牌局历史记录。

如何在代码中修改 .XML 布局或以其他方式向布局添加新的 TextView？

我试过...

public static LinearLayout gamehistory;

gamehistory = (LinearLayout) findViewById(R.id.gamehistory);


public void setClickListener1(){

lockwagersButton.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

setContentView(R.layout.results_layout);

gameHistory.addView(new TextView(...));       //  I can't get this to work 
            ...

谢谢!-K.H.

以下代码添加 textview onclick:

public class ViewOnClick extends Activity {
    LinearLayout.LayoutParams layoutParams;
    LinearLayout ll;
    static int i;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button b = (Button)findViewById(R.id.Button01);
        ll = (LinearLayout)findViewById(R.id.ll);
        layoutParams = new LinearLayout.LayoutParams
        (LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        b.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {
                TextView view = new TextView(ViewOnClick.this);             
                view.setText(++i+" view");
                ll.addView(view, layoutParams); 

            }
        });
    }
}
