Question

我在意图的帮助下发送图像如下

Uri profileImage = Uri.parse("android.resource://Tset/res/drawable-hdpi/arr.jpeg");
            details.setType("image/png");
            details.putExtra(Intent.EXTRA_STREAM, profileImage);
            startActivity(details);

如何在接收端活动中获取图像路径？

Answer 1

试试这个使用意图

从当前活动传递图像网址

Intent myIntent = new Intent(this, MyImageViewActivity.class);
Bundle bundle = new Bundle();
bundle.putString("image", path);
myIntent.putExtras(bundle);
startActivityForResult(myIntent, 0);

这里的路径是

String path="android.resource://Tset/res/drawable-hdpi/arr.jpeg"

在您的接收活动中

Bundle bundle = this.getIntent().getExtras();
String path = bundle.getString("image");

最后我在图片的id的帮助下完成了如下操作！！谢谢你的回复！！

  profilePictureID=R.drawable.image name;//name of image in drawable folder dont use extensions like.jpg and all  
  IntentObject.putExtra("ImageID",profilePictureID);
  startActivity(IntenetObject);

接收活动

 int pictureId=getIntent().getIntExtra("ImageID",0);
 profilePicture.setImageResource(pictureId);

Answer 3

在您的通话活动中......

 Intent i = new Intent(this, NextActivity.class);
 Bitmap b; // your bitmap
 ByteArrayOutputStream bs = new ByteArrayOutputStream();
 b.compress(Bitmap.CompressFormat.PNG, 50, bs);
 i.putExtra("byteArray", bs.toByteArray());
 startActivity(i);

...并在您的接收活动中

if(getIntent().hasExtra("byteArray")) {
    ImageView previewThumbnail = new ImageView(this);
     Bitmap b = BitmapFactory.decodeByteArray(
     getIntent().getByteArrayExtra("byteArray"),0,getIntent().getByteArrayExtra("byteArray").length);        
     previewThumbnail.setImageBitmap(b);
}


   File imgFile = new  File(“/sdcard/Images/test_image.jpg”);
   if(imgFile.exists())
      Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());

Answer 4

试试这个..

Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
startActivity(intent);

Answer 5

您可以转换为bytearray并传递相同的内容。在下一个活动中解码并显示相同内容。

使用意图传递图像

Intent i = new Intent(this, NextActivity.class);
Bitmap b; // your bitmap
ByteArrayOutputStream bs = new ByteArrayOutputStream();
b.compress(Bitmap.CompressFormat.PNG, 50, bs);
i.putExtra("byteArray", bs.toByteArray());
startActivity(i);

接收

if(getIntent().hasExtra("byteArray")) {
    ImageView previewThumbnail = new ImageView(this);
    Bitmap b = BitmapFactory.decodeByteArray(
        getIntent().getByteArrayExtra("byteArray"),0,getIntent().getByteArrayExtra("byteArray").length);        
    previewThumbnail.setImageBitmap(b);
}

如果您要传递字符串网址

How do you pass a string from one activity to another?

编辑：

通过uri

 Uri uri = Uri.parse("android.resource://com.example.passurl/drawable/ic_launcher");
 // com.example.passurl is the package name
 // ic_launcher is the image name
 Intent i = new Intent(MainActivity.this,NewActivity.class);
 i.setData(uri);
 startActivity(i);

接收

ImageView iv= (ImageView) findViewById(R.id.imageView1); // initialize image view
if(getIntent().getData()!=null)
{
 Uri path = getIntent().getData();
 iv.setImageURI(path);  //set the image 
}

如何使用Intents接收图像文件？
