android中动态布局(动态加入TextView和ListView)

public class Main extends Activity {

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.friend_info_view);		
		final LinearLayout linearLayout = (LinearLayout) findViewById(R.id.groups);
		
		final ListView lv = new ListView(this);
		List<Map<String, Object>> data = new ArrayList<Map<String, Object>>();
		Map<String, Object> map = new HashMap<String, Object>();
		map.put("title", "jayqean");

		// ------------------------
		// 加入分割线
		final TextView line = new TextView(this);
		line.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 1));
		line.setBackgroundColor(Color.WHITE);
		linearLayout.addView(line, 1);
		// ------------------------
		final ListView lv2 = new ListView(this);

		data2.add(map2);

					linearLayout.removeView(lv2);
					flag = false;

			}
		});
		linearLayout.addView(tv2, 2);
		
		
	}
}

控制布局,可以通过RelativeLayout.LayoutParams类

final LinearLayout linearLayout = (LinearLayout) findViewById(R.id.groups);

final TextView tv1 = new TextView(this);
tv1.setText("常用联系人");

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); // 线性布局 通过参数index控制加入的控件的位置
