客户有个要求：制作一个APK，点击之后直接打开客户的产品介绍的PDF文档
1、需要定义一个打开pdf的Intent
/**
* Get PDF file Intent
*/
public Intent getPdfFileIntent(String path){
Intent i = new Intent(Intent.ACTION_VIEW);
i.addCategory(Intent.CATEGORY_DEFAULT);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
Uri uri = Uri.fromFile(new File(path));
i.setDataAndType(uri, "application/pdf");
return i;
}
2、在onCreate函数中用这个Intent打开指定的文件：
Intent intent = getPdfFileIntent("/mnt/sdcard/startup_guide.pdf");
startActivity(intent);
finish();
3、当然在有了这个APK之后，您的系统中需要安装了Adobe player
PS：整个实现功能的代码如下：
package com.yds.topdf;
import java.io.File;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
public class TopdfActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getPdfFileIntent("/mnt/sdcard/startup_guide.pdf");
startActivity(intent);
finish();
}
/**
* Get PDF file Intent
*/
public Intent getPdfFileIntent(String path){
Intent i = new Intent(Intent.ACTION_VIEW);
i.addCategory(Intent.CATEGORY_DEFAULT);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
Uri uri = Uri.fromFile(new File(path));
i.setDataAndType(uri, "application/pdf");
return i;
}
}
