我编写了以下代码来读取和显示我的Android应用程序中的html文件。但活动没有开始。它显示“不幸的应用程序停止工作”。 java类如下：
package com.radiobot.speedreaderv1_1;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.webkit.WebView;
import android.widget.TextView;
public class htmlViewer extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.htmlviewer);
WebView wv = (WebView) findViewById(R.id.webView1);
TextView tv = (TextView)findViewById(R.id.fileContent);
File dir = Environment.getExternalStorageDirectory();
// Bundle extras = getIntent().getExtras();
// String newloc = extras.getString("loc");
File file = new File(dir,"test.html");
if(file.exists())
{
StringBuilder text = new StringBuilder();
try {
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
while ((line = br.readLine()) != null) {
text.append(line);
text.append('\n');
}
}
catch (IOException e) {
}
// tv.setText(text);
String html = text.toString();
String mimeType = "text/html";
String encoding = "UTF-8";
wv.loadDataWithBaseURL("",html, mimeType, encoding, "");
}
else
{
tv.setText("Sorry file doesn't exist!!");
}
}
}
logcat如下：
