Android编程中关于layout(l,t,r,b)函数的问题？

Question

public class Test0812Activity extends Activity {/** Called when the activity is first created. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);AbsoluteLayout layer = (AbsoluteLayout)findViewById(R.id.AbsoluteLayout01);CheckBox btt = new CheckBox(this);layer.addView(btt);btt.setText("4567");btt.layout(100, 100, 200, 200);btt.postInvalidate();}}为什么生成的CheckBox总是出现在左上角，而不是layout函数中规定的100,100,200,200？需要怎么改可以解决这个问题？

Answer 1

btt.setText("4567");
btt.layout(100, 100, 200, 200);
btt.postInvalidate();
layer.addView(btt);
你这样排版试试
