【android】根据屏幕分辨率设置底栏高度

<pre name="code" class="java">	public void setFooterHeightWithScreen()
	{
		//得到屏幕分辨率
		int srcWidth  =getWindowManager().getDefaultDisplay().getWidth();
		// Log.i("f", srcWidth.toString());
		//System.out.print(srcWidth);

		//得到按钮
		Button b1 = (Button) findViewById(R.id.footer1);
		Button b2 = (Button) findViewById(R.id.footer2);
		Button b3 = (Button) findViewById(R.id.footer3);
		Button b4 = (Button) findViewById(R.id.footer4);

		//得到按钮图片的高
		Drawable r=this.getResources().getDrawable(R.drawable.main_hunt0);
		BitmapDrawable b=(BitmapDrawable)r;
		Bitmap t=b.getBitmap();
		t.getHeight();
		//通过按钮得到父控件 根据屏幕分辨率设置高
		LinearLayout.LayoutParams l=(LayoutParams) b1.getLayoutParams();
		int i=(int)((srcWidth/4.0* t.getHeight())/(t.getWidth()));
		l.height=i;
		b1.setLayoutParams(l);
		b2.setLayoutParams(l);
		b3.setLayoutParams(l);
		b4.setLayoutParams(l);
		// int i=(int)((srcWidth/4.0* b1.getHeight())/(b1.getWidth()));
		// b1.setHeight(i);
