android 动态控件大小

// 屏幕方面切换时获得方向
  if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
   setTitle("landscape");
  }
  if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
   setTitle("portrait");
  }
  // 获得屏幕大小1
  WindowManager manager = getWindowManager();
  int width = manager.getDefaultDisplay().getWidth();
  int height = manager.getDefaultDisplay().getHeight();
  // 获得屏幕大小2
  DisplayMetrics dMetrics = new DisplayMetrics();
  getWindowManager().getDefaultDisplay().getMetrics(dMetrics);
  int screenWidth = dMetrics.widthPixels;
  int screenHeight = dMetrics.heightPixels;


利用getLayoutParams()方法和setLayoutParams()方法。


1、首先利用getLayoutParams()方法,获取控件的LayoutParams。
eg:LayoutParamslaParams=(LayoutParams)imageView.getLayoutParams();
2、设置该控件的layoutParams参数
eg:    laParams.height=xxx;
      laParams.width=yyy;
3、将修改好的layoutParams设置为该控件的layoutParams.
eg:imageView.setLayoutParams(laParams);
