我有一个问题：我有一个函数，使我从库中的形象;但是当我选择的形象，我不明白这一点。

 公共无效funzione（视图v）{
INT SELECT_IMAGE = 1;
意向意图=新的意图（）;
intent.setType（图像/ *）;
intent.setAction（Intent.ACTION_GET_CONTENT）;
startActivityForResult（Intent.createChooser（意向，选择图片），SELECT_IMAGE）;
 

我要通过电子邮件发送这个形象，但我现在不如何实现这一点：

 意向书我=新意图（）;
i.setType（应用程序/八位字节流）;
i.setAction（Intent.ACTION_SEND）;
i.putExtra（android.content.Intent.EXTRA_EMAIL，新的String [] {prova@libero.it}）;
i.putExtra（android.content.Intent.EXTRA_SUBJECT，测试SUBJ）;
i.putExtra（android.content.Intent.EXTRA_TEXT，CORPO邮件测试）;
startActivity（Intent.createChooser（我，发送电子邮件））;

}
 

解决方案

刚过类声明顶部声明全局变量：

 私有静态诠释RESULT_LOAD_IMAGE = 1;
 私有静态最终诠释PICK_FROM_GALLERY = 2;
 位图的缩略图= NULL;
 

调用这样的意向：（您funizone（）函数）

 公共无效funzione（）{
       意图=新的意图（Intent.ACTION_PICK，android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI）;
                      startActivityForResult（在，RESULT_LOAD_IMAGE）;

   }
 

处理结果是这样的：在类的任何位置声明你的onCreate此之外

 保护无效onActivityResult（INT申请code，INT结果code，意图数据）{

    super.onActivityResult（要求code，因此code，数据）;

     如果（要求code == RESULT_LOAD_IMAGE和放大器;＆安培;结果code == RESULT_OK和放大器;＆安培;！NULL =数据）{

         乌里selectedImage = data.getData（）;
            的String [] filePathColumn = {MediaStore.Images.Media.DATA};
            光标光标= getContentResolver（）查询（selectedImage，filePathColumn，NULL，NULL，NULL）;
            cursor.moveToFirst（）;
            INT参数：columnIndex = cursor.getColumnIndex（filePathColumn [0]）;
            字符串picturePath = cursor.getString（参数：columnIndex）;
            cursor.close（）;
            缩略图=（BitmapFactory.de codeFILE（picturePath））;
 

缩略图是你的照片了，现在用它玩！

I have a problem: I have a function that brings me the image from the gallery ;but when I select the image, I don't get it.

public void funzione(View v){
int SELECT_IMAGE=1;
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),SELECT_IMAGE);

I have to email this image, but I don't now how to implement this:

Intent i = new Intent();
i.setType("application/octet-stream"); 
i.setAction(Intent.ACTION_SEND);
i.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{ "prova@libero.it" });
i.putExtra(android.content.Intent.EXTRA_SUBJECT, "Test subj");
i.putExtra(android.content.Intent.EXTRA_TEXT, "corpo mail test");
startActivity(Intent.createChooser(i, "Send email"));

}

Declare Global Variables just after your class declaration at the top:

 private static int RESULT_LOAD_IMAGE = 1;
 private static final int PICK_FROM_GALLERY = 2;
 Bitmap thumbnail = null; 

Call the intent like this: (Your funizone() function)

   public void funzione(){
       Intent in = new   Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                      startActivityForResult(in, RESULT_LOAD_IMAGE);

   }

Handle the result like this: Declare this outside of your onCreate anywhere in the class.

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {  

    super.onActivityResult(requestCode, resultCode, data);     

     if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data){

         Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();
            thumbnail = (BitmapFactory.decodeFile(picturePath));

thumbnail is your picture, now play with it!
