我和Android的一个初学者,目前套牢lession: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!
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.
