Answer 1

以下是示例代码。您可以根据需要对其进行配置：

public class MainActivity extends Activity {

private Button button;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    webView = (WebView) findViewById(R.id.webView);
    googleButton = (Button) findViewById(R.id.buttonUrl);

    googleButton.setOnClickListener(new OnClickListener() {

      @Override
      public void onClick(View v) {
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl("http://www.google.com");
      }

    });
}
}

请注意，您的清单中需要获得INTERNET权限：

<uses-permission android:name="android.permission.INTERNET" />

Answer 2

您只需要在按钮的onClickListener中添加java代码：

String[] input = getInputContents(inFile);
List<String> currentBuffer = new ArrayList<String>();
List<String[]> buffers = new ArrayList<String[]>();

for(String line : input) {
    if(line.equals("0")) {
        buffers.add((String[])currentBuffer.toArray());
        currentBuffer = new ArrayList<String>();
    } else {
        currentBuffer.add(line);
    }
}
