        while( (len = inStream.read(buffer)) != -1 ){
            outStream.write(buffer, 0, len);
        }
        inStream.close();
        return outStream.toByteArray();
    }
}</span>

网页源码查看器

如果网页的源码超过屏幕的显示位置的话，要求出现滚动条.

view plain
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/htmlsource"
/>
</ScrollView>

界面如下：

示例

view plain
@Override
public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      pathText = (EditText) this.findViewById(R.id.path);
      htmlsource = (TextView) this.findViewById(R.id.htmlsource);

      Button button = (Button) this.findViewById(R.id.button);
      button.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {
        String path = pathText.getText().toString();
        try{
            //获取源码
            String html = PageService.getHtml(path);
            htmlsource.setText(html);
        }catch (Exception e) {
            Toast.makeText(getApplicationContext(), R.string.error, 1).show();
        }
    }
});
}
