　　控制布局,可以通過RelativeLayout.LayoutParams類

　　?

1 2 3 4 5 6 7 final LinearLayout linearLayout = (LinearLayout) findViewById(R.id.groups); final TextView tv1 = new TextView(this); tv1.setText("常用聯系人"); RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT); lp1.addRule(RelativeLayout.BELOW, R.id.groups); tv1.setLayoutParams(lp1); linearLayout.addView(tv1, lp1);

　　也可采用linearLayout.addView(tv1, 0); // 線性布局 通過參數index控制加入的控件的位置
