坚持@燮pressLint（＆QUOT; NewApi＆QUOT;）（developer.android.com/training/basics/firstapp/starting-activity） [英] Stuck with @SuppressLint("NewApi") (developer.android.com/training/basics/firstapp/starting-activity)

问题描述

我和Android的一个初学者，目前套牢lession：<一href="http://developer.android.com/training/basics/firstapp/starting-activity.html">http://developer.android.com/training/basics/firstapp/starting-activity.html

I'm a begginer with Android and currently stuck with the lession: http://developer.android.com/training/basics/firstapp/starting-activity.html

在部分创建第二个活动，当我尝试使用code：

In the part Create the Second Activity, when I try to use the code:

public class DisplayMessageActivity extends Activity {

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_display_message);

        // Make sure we're running on Honeycomb or higher to use ActionBar APIs
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            // Show the Up button in the action bar.
            getActionBar().setDisplayHomeAsUpEnabled(true);
        }
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case android.R.id.home:
            NavUtils.navigateUpFromSameTask(this);
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

我收到以下错误：

I get the error below:

@燮pressLint（NewApi） - >属性值是不确定的注释类型燮pressLint

@SuppressLint("NewApi") -> The attribute value is undefined for the annotation type SuppressLint.

如果（Build.VERSION.SDK_INT> = Build.VERSION_ codeS 蜂窝。） - >蜂窝不能得到解决，或者不是一个领域

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) -> HONEYCOMB cannot be resolved or is not a field.

getActionBar （）setDisplayHomeAsUpEnabled（真）。 - >该方法getActionBar（）是未定义的类型DisplayMessageActivity

getActionBar().setDisplayHomeAsUpEnabled(true); -> The method getActionBar() is undefined for the type DisplayMessageActivity.

NavUtils .navigateUpFromSameTask（本）; - > NavUtils解决不了

NavUtils.navigateUpFromSameTask(this); -> NavUtils cannot be resolved

有人让我知道该如何解决？ 以下是我的输入：

Someone let me know how to solve? Here is what I imported:

import android.app.Activity;
import android.os.Build;
import android.os.Bundle;
import android.view.MenuItem;

非常感谢！

推荐答案

您生成目标未设置为API级别14或更高。这是不是一个错误，请关闭这个问题。

Your build target is NOT set to API Level 14 or higher. This is not a bug, please close this issue.

（在Eclipse：项目=>属性=>安卓）
