【问题描述】:
我在 Stackoverflow 上看到了很多关于使用 phonegap 开发应用程序时两个 html 页面之间的故障/间隔/间隙的问题。我找到了一个用于phonegap 的插件slider plugin。经过大量搜索后,我无法弄清楚如何执行此步骤 3。
Add the import for your resource Java file (yourpackage.R) to LoadingSpinner.java
这在我看来像是原生代码,但我无法理解。
我的问题是:
- yourpackage.R 文件是什么??
- 它在哪里??
- 那里给出的第 3 步该怎么做??
谢谢
------------编辑-----------
这里是R.java的内容
package com.somethingsomething.appone;
public final class R {
public static final class attr {
}
public static final class drawable {
public static final int ic_launcher=0x7f020000;
}
public static final class layout {
public static final int main=0x7f030000;
}
public static final class string {
public static final int app_name=0x7f060001;
public static final int hello=0x7f060000;
}
public static final class style {
public static final int loading_spinner=0x7f050000;
}
public static final class xml {
public static final int cordova=0x7f040000;
public static final int plugins=0x7f040001;
}
}
LoadingSpinner.java 的内容是
package de.sandstein.phonegap.plugin.transition;
import android.app.Dialog;
import android.content.Context;
import android.view.ViewGroup.LayoutParams;
import android.widget.ProgressBar;
public class LoadingSpinner extends Dialog {
public static LoadingSpinner show(Context context, CharSequence title,
CharSequence message) {
return show(context, title, message, false);
}
public static LoadingSpinner show(Context context, CharSequence title,
CharSequence message, boolean indeterminate) {
return show(context, title, message, indeterminate, false, null);
}
public static LoadingSpinner show(Context context, CharSequence title,
CharSequence message, boolean indeterminate, boolean cancelable) {
return show(context, title, message, indeterminate, cancelable, null);
}
public static LoadingSpinner show(Context context, CharSequence title,
CharSequence message, boolean indeterminate,
boolean cancelable, OnCancelListener cancelListener) {
LoadingSpinner dialog = new LoadingSpinner(context);
dialog.setTitle(title);
dialog.setCancelable(cancelable);
dialog.setOnCancelListener(cancelListener);
/* The next line will add the ProgressBar to the dialog. */
dialog.addContentView(new ProgressBar(context), new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
dialog.show();
return dialog;
}
public LoadingSpinner(Context context) {
super(context, R.style.loading_spinner);
}
}
在 LoadingSpinner.java 中导入 R.java 为
import android.R;
现在是错误状态
loading_spinner cannot be resolved or is not a field
------------编辑-----------
在 LoadingSpinner.java 文件中将 android.R 替换为 com.somethingsomething.appone.R
import com.somethingsomething.appone.R;
仍然是错误状态
loading_spinner cannot be resolved or is not a field
清理项目并重新启动eclipse,错误就消失了。
用法说
1) Call initTransition() on startup of the app.
2) Call showLoadingView() to show the loading view. (Android: can use parameter "animation" ('slide' oder 'fade'))
3) When the animation has finished 'transitionAnimationReady' is fired.
4) Call hideLoadingView() to hide the loading view.
我在哪里可以找到声明这些全局函数以便它适用于所有文件的地方。
它应该在其他文件中,在html标签上方的html文件中,在head标签中。尝试将以下代码放在 html 上方和 head 标记中。
<script type="text/javascript" charset="utf-8" src="transition.js"></script>
<script type="text/javascript">
initTransition();
showLoadingView('slide');
hideLoadingView();
alert("hi");
</script>
