Question

我试图创建等级评论并在等级图像旁边完成后显示等级评级。我的代码准备就绪并在完成级别后显示评级我将得分值保存到共享首选项并检查值这是代码

// adding value to cookies from First Activity 
Editor editor = sharedpreferences.edit(); editor.putInt("level1_rating",AllGlobalVariables.level_score ); editor.putInt("level2_rating",AllGlobalVariables.level2_score );
editor.commit(); 

// calling function in Second Activity
rating(AllGlobalVariables.level1);	


//------ function defination --------//

private void rating(String l) {
	// TODO Auto-generated method stub
		
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);

		int left = 15;
		int top = 65;
		int right=0;
		int bottom=0;
		lp.setMargins(left, top, right, bottom);
if(l.equals("1")){
if (sharedpreferences.contains("level1_rating"))
  {
if(AllGlobalVariables.level_score <= 50){
			
Bitmap goodbmp = BitmapFactory.decodeResource(getResources(), R.drawable.fail);
String goodimagecode = BitMapToStringgood(goodbmp);
Bitmap goods = StringToBitMapgoods(goodimagecode);
Drawable verticalImage = new BitmapDrawable(getResources(), goods);
AllGlobalVariables.Rimagel1 = (ImageView) findViewById(R.id.imageView6); AllGlobalVariables.Rimagel1.setImageDrawable(verticalImage);
	      }
}
}
}

但问题是：我能够获得价值形式密钥，但无法比较共享偏好键的值以显示评级。请建议如何比较密钥的值

或者还有其他想法可以做这项工作，建议将非常感激

谢谢

如果首选项包含首选项true，则

SharedPreferences.contains返回false。

使用SharedPreferences.getInt获取整数值，然后与其他值进行比较：

if (sharedpreferences.contains("level1_rating"))
{
   int level1_ratingValue=sharedpreferences.getInt("level1_rating",0);;
    if(level1_ratingValue==70){
      // do work if condition true
    }else{
      // do work if condition false
    }
}

如何比较保存到共享首选项中的Int值
