android-在Android中以編程方式創建一個RelativeLayout

在Android中以編程方式創建一個RelativeLayout

我添加兩個按鈕到UI,但它們在界面上是上下顯示的。我想實現的是它們左右顯示。我用的這段代碼還缺什麼啊?請大家幫我檢查下，謝謝。

m_btnCrown = new ImageButton(this);
m_btnCrown.setImageResource(R.drawable.king_crown_thumb);
m_btnCrown.setAlpha(100);

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);


addContentView(m_btnCrown, lp);


m_btnMonkey = new ImageButton(this);
m_btnMonkey.setImageResource(R.drawable.monkey_small);
m_btnMonkey.setAlpha(100);

lp = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
lp.addRule(RelativeLayout.RIGHT_OF, m_btnCrown.getId());   

addContentView(m_btnMonkey, lp);

最佳回答：

我寫了一個簡單的例子來演示如何以編程方式創建一個布局:
public class CodeLayout extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // 創建一個新的RelativeLayout
    RelativeLayout relativeLayout = new RelativeLayout(this);

    // 定義RelativeLayout布局屬性  
    RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.FILL_PARENT,
            RelativeLayout.LayoutParams.FILL_PARENT);

    // 創建一個新的TextView
    TextView tv = new TextView(this);
    tv.setText("Test");

    // 定義TextView裡的布局屬性
    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT);
    lp.addRule(RelativeLayout.CENTER_IN_PARENT);

    //設置 TextView的屬性 
    tv.setLayoutParams(lp);

    relativeLayout.addView(tv);

    setContentView(relativeLayout, rlp);
}

}
