我是新的android应用开发。我也没有那么多的想法。所以，请帮助我。
I am new to android application development. And I have not that much idea. So Please Help me.
的.java文件的位置在src / my_package_name文件夹和.html文件的位置是在资产/ www文件夹。
Location of .java file is in src/my_package_name folder and location of .HTML file is in assets/www folder.
我想在HTML文件中的锚标记这个做的，我已经给 HREF =ContactUs.java链接。这是行不通的。
I am trying to do with this by anchor tag in html file, I have given href="ContactUs.java" to link. It is not working.
模拟器显示我的错误。这就是应用程序错误。所请求的文件没有被发现。 ContactUs.java（文件：///android_asset/ContactUs.java）
Emulator shows me error. That is Application Error. The Requested file was not found. ContactUs.java(file:///android_asset/ContactUs.java).
我不知道这是正确的方式与否。
I am not sure it is correct way or not.
所以，请给我建议，如果有什么更好的方式来做到这一点？
So please Suggest me if there is any better way to do this?
在此先感谢..
推荐答案
下面是从HTML打开活动的解决方案。
Here is a solution to open an activity from html.
首先包含您的WebView您的主要活动：
First your main activity containing your webview:
package com.test.jsitest;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class WVActivity extends Activity {
private WebView m_wv = null;
@SuppressLint("SetJavaScriptEnabled")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_wv);
m_wv = (WebView) findViewById(R.id.webview);
m_wv.getSettings().setJavaScriptEnabled(true);
m_wv.loadUrl("file:///android_asset/www/index.html");
m_wv.addJavascriptInterface(new ActivityLauncher(this), "Android");
}
}
然后你的Javascript接口：
Then your Javascript Interface:
package com.test.jsitest;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
public class ActivityLauncher {
private Context m_context;
public ActivityLauncher(Context context) {
m_context = context;
}
public void launchActivity() {
m_context.startActivity(new Intent((Activity)m_context,
Activity2.class)); // Here you replace by your activity (ContactUs)
}
}
和finaly您的HTML文件：
And finaly your html file:
<DOCTYPE html>
<html>
<head>
</head>
<body>
<a href="javascript:Android.launchActivity()">Link</a>
</body>
</html>
