如何调用wps打开我下载的文本文件？

摘要: 今天闲来无事，试了一下，感觉还好 觉得有用的同学们可以点赞啊，花了我一下午时间才搞出来还是挺有用的哦~
感谢这个哥哥的分享http://blog.csdn.net/wangyang2698341/article/details/20847469

这里写的有三个按钮
根据按钮的id不难发现各个按钮点击的触发事件，第一个是下载百度首页的html代码，第二个是显示我下载的文件的文本内容的代码，第三个是调用第三方应用程序比如wps打开此类文件。

package com.example.wps;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;

public class MainActivity extends Activity implements OnClickListener {

private Button download;

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

wps.setOnClickListener(this);
}

@Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.download:
new Thread(new Runnable() {
@Override
public void run() {

HttpClient client=new DefaultHttpClient();
String url="http://www.baidu.com/";
HttpGet request=new HttpGet(url);
try {
HttpResponse response=client.execute(request);
if(response.getStatusLine().getStatusCode()==200){
InputStream is=response.getEntity().getContent();
int len=0;
byte[] read=new byte[1024];
File file=new File(Environment.getExternalStorageDirectory(),"baidu.txt");
if (!file.exists()) {
file.createNewFile();
}else{
Looper.prepare();
Toast.makeText(MainActivity.this, "文件夹存在",0).show();
Log.i("file", file.getAbsolutePath());
Looper.loop();
}
FileOutputStream fos=new FileOutputStream(file);
while((len=is.read(read))!=-1){
fos.write(read, 0, len);
}
is.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
break;
case R.id.show:
File file=new File(Environment.getExternalStorageDirectory(),"baidu.txt");
if(file.exists()){
try {

int len=0;
byte[] buffer=new byte[1024];
ByteArrayOutputStream baos=new ByteArrayOutputStream();
while ((len=fis.read(buffer))!=-1) {
baos.write(buffer,0,len);
}
fis.close();
baos.close();
tv.setText(new String(baos.toByteArray(),"utf-8"));
} catch (Exception e) {
e.printStackTrace();
}
}else{
Toast.makeText(this, "file不存在", 0).show();
}
break;
case R.id.wps:
File file2=new File(Environment.getExternalStorageDirectory(),"baidu.txt");
if(file2.exists()){
Intent intent = new Intent();
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setAction(android.content.Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(file2);
intent.setDataAndType(uri, "application/msword");
//intent.setComponent(new ComponentName("cn.wps.moffice", "cn.wps.moffice.documentmanager.PreStartActivity"));
startActivity(intent);
}
break;
default:
break;
}

}
}
