<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);	}
