[英]eclipse android project error remind
我从googlecode下载了一个开源android项目。 它的名字叫OSMAND
。 通过将java compile version to 1.6
设置java compile version to 1.6
并将android version to 4.0
。 "net.osmand.plus.activities.MainMenuActivity"
项目只有Eclipse IDE警告的三个错误:
错误的两个在类AccessibilityDelegat
,
我要求osmand谷歌群体。 我不知道为什么因为每周或其他原因而无法回答我的问题。 所以我在这里问。
package net.osmand.access;
import net.osmand.access.AccessibleLayout;
import android.app.Activity;
import android.app.Dialog;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.widget.FrameLayout;
// This class serves as a delegate of accessibility service
// providing a sort of touch exploration capability
// for a View hierarchy. It means that elements will be spoken
// on touch. Thus, you can slide your finger across the screen
// and hear available controls and items.
// Lift finger up on a control to make click.
//
// This class can not be instantiated directly.
// Use static method takeCareOf() to get it's functionality
// for respective objects.
//
public class AccessibilityDelegate extends AccessibleLayout {
private AccessibilityDelegate(Context context) {
super(context);
}
// Attach itself to a target View hierarchy to intercept touch events
// and provide on-touch accessibility feedback.
// Target View must be an instance of FrameLayout
// or have a parent which is an instance of ViewGroup.
private void attach(View target) {
ViewGroup parent;
if (target instanceof FrameLayout) {
parent = (ViewGroup)target;
while (parent.getChildCount() > 0) {
View child = parent.getChildAt(0);
parent.removeViewAt(0);
addView(child);
}
parent.addView(this, new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
} else if (target.getParent() instanceof ViewGroup) {
parent = (ViewGroup)target.getParent();
int position = parent.indexOfChild(target);
ViewGroup.LayoutParams params = target.getLayoutParams();
parent.removeViewAt(position);
addView(target, new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
parent.addView(this, position, params);
}
}
// Provide touch exploration capability for individual View
// or whole View hierarchy. The hierarchy root specified
// as an argument must either be an instance of FrameLayout
// or have a parent that is an instance of ViewGroup.
public static void takeCareOf(View hierarchy) {
final AccessibilityDelegate delegate = new AccessibilityDelegate(hierarchy.getContext());
delegate.attach(hierarchy);
}
// Provide touch exploration capability for given window.
public static void takeCareOf(Window window) {
takeCareOf(window.getDecorView());
}
// Provide touch exploration capability for an activity View content.
// Use after setContentView().
public static void takeCareOf(Activity activity) {
takeCareOf(activity.getWindow());
}
// Provide touch exploration capability for a dialog View content.
// Use after setContentView().
public static void takeCareOf(Dialog dialog) {
takeCareOf(dialog.getWindow());
}
}
它提醒我:
The constructor View.AccessibilityDelegate(Context) is undefined
Resource: AccessibilityDelegate.java
Path: /net.osmand.plus.activities.MainMenuActivity/src/net/osmand/access
Location:line 60 Type:Java Problem.
此错误出现在句子“最终AccessibilityDelegate委托= new AccessibilityDelegate(hierarchy.getContext());”中,我在这里进行了分隔(以方便通知)
和
The method attach(View) is undefined for the type View.AccessibilityDelegate
Resource:AccessibilityDelegate.java
Path:/net.osmand.plus.activities.MainMenuActivity/src/net/osmand/access
Location: line 61 Type:Java Problem
this error appear in the next of my seperated line, in sentence "delegate.attach(hierarchy);"
但我在此类中看到,有构造函数和attach方法定义。 我不知道问题出在哪里以及如何解决
似乎您正在被编译器使用View.AccessibilityDelegate。 尝试改用标准名称,如下所示:
final net.osmand.access.AccessibilityDelegate delegate = new net.osmand.access.AccessibilityDelegate(hierarchy.getContext());
它应该与此一起工作。
