动态加载布局的几种方式

View views =
    // View v =LayoutInflater.from(MainActivity.this).inflate(
    // R.layout.dialog, null);
    
    // LayoutInflater inflater = (LayoutInflater) MainActivity.this
    // .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    // View views = inflater.inflate(R.layout.dialog, null);
    
    LinearLayout views = (LinearLayout) getLayoutInflater()
      .inflate(R.layout.dialog, null);
    
    new AlertDialog.Builder(MainActivity.this).setTitle("aaaa")
      .setView(views).show();

final LinearLayout lin =(LinearLayout)findViewById(R.id.LinearLayout01);
LinearLayout layout = (LinearLayout) inflater.inflate(
                        R.layout.listview, null).findViewById(R.id.layout);
 lin.addView(layout);

View v =LayoutInflater.from(MainActivity.this).inflate(
    // R.layout.dialog, null);
setContentView(v);

 动态设置布局的宽高

View v =LayoutInflater.from(MainActivity.this).inflate(
    // R.layout.dialog, null);
RelativeLayout.LayoutParams albumLay = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT,
				LayoutParams.WRAP_CONTENT);
v.setLayoutParams(albumLay);

 获取手机的宽高,动态设置布局在屏幕中的比例

DisplayMetrics dm = new DisplayMetrics();
		getWindowManager().getDefaultDisplay().getMetrics(dm);
		int width = dm.widthPixels;
		int height = dm.heightPixels;
		application.screenWidth = width;
		application.screenHeight = height;
RelativeLayout.LayoutParams albumLay = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT,

				LayoutParams.WRAP_CONTENT);
				albumLay.setMargins(50, (int) ((height * 0.45) * ((height * 0.45) * 0.48 / (height * 0.45))), 50,

				0);
				findViewById(R.id.album).setLayoutParams(albumLay);
