（代码）Android 实现调用wps打开word文档，打开pdf文档

废话不多说，直接看代码，新建个activity，声明，点击事件，省略。亲测可用，看代码 

Button lookdoc;
lookdoc = (Button)findViewById(R.id.lookdoc);
lookdoc.setOnClickListener(looklisten);OnClickListener looklisten = new OnClickListener() {@Overridepublic void onClick(View v) {DownLoadUtil d = new DownLoadUtil();//获取文件的类型String filetype = filename.substring(filename.lastIndexOf(".")+1,filename.length());if("jpg".equals(filetype)||"jpeg".equals(filetype)||"bmp".equals(filetype)||"gif".equals(filetype)||"png".equals(filetype)){Toast.makeText(PreceptInfoActivity.this, "文件类型错误", Toast.LENGTH_LONG).show();}else{//检测是否安装了wps软件，没有安装则去下载if(isAvilible(PreceptInfoActivity.this, "cn.wps.moffice_eng")){//先查看本地是否存在此文件。存在就立即访问。否则再去下载// 获得存储卡的路径String sdpath = Environment.getExternalStorageDirectory()+ "/";String sdcard2 = sdpath + "download/"+DownLoadUtil.urldecodeUTF8(filename).substring(DownLoadUtil.urldecodeUTF8(filename).lastIndexOf("/")+1);File file = new File(sdcard2);// 判断文件目录是否存在if (file.exists()) {Intent intent = new Intent();Bundle bundle = new Bundle();bundle.putString("OpenMode", "ReadOnly");// 只读模式intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);intent.setAction(android.content.Intent.ACTION_VIEW);intent.setClassName("cn.wps.moffice_eng","cn.wps.moffice.documentmanager.PreStartActivity2");Uri uri = Uri.fromFile(new File(sdcard2));Log.e("wps访问的uri", uri+"");intent.setData(uri);intent.putExtras(bundle);try {startActivity(intent);} catch (ActivityNotFoundException e) {e.printStackTrace();} }else{//返回真实路径mSavePath = d.downloadFile(filename);if(mSavePath!=""){Intent intent = new Intent();Bundle bundle = new Bundle();bundle.putString("OpenMode", "ReadOnly");// 只读模式intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);intent.setAction(android.content.Intent.ACTION_VIEW);intent.setClassName("cn.wps.moffice_eng","cn.wps.moffice.documentmanager.PreStartActivity2");Uri uri = Uri.fromFile(new File(mSavePath+DownLoadUtil.urldecodeUTF8(filename.substring(filename.lastIndexOf("/")+1,filename.length()))));Log.e("wps访问的uri", uri+"");intent.setData(uri);intent.putExtras(bundle);try {startActivity(intent);} catch (ActivityNotFoundException e) {e.printStackTrace();} }else{mDownloadDialog.show();Toast.makeText(PreceptInfoActivity.this, "下载中", Toast.LENGTH_SHORT).show();}}}else{// 从市场上下载Uri uri = Uri.parse("market://details?id=cn.wps.moffice_eng");// 直接从指定网址下载Intent it = new Intent(Intent.ACTION_VIEW, uri); startActivity(it); }}}};

private boolean isAvilible( Context context, String packageName ){final PackageManager packageManager = context.getPackageManager();// 获取所有已安装程序的包信息List<PackageInfo> pinfo = packageManager.getInstalledPackages(0);for ( int i = 0; i < pinfo.size(); i++ ){if(pinfo.get(i).packageName.equalsIgnoreCase(packageName))return true;}return false;}
