获取图片URI

Question

我想分享图片，但我不确定如何获取图像的URI在这里：

imageView.setOnClickListener(new OnClickListener() { 
    @Override 
    public void onClick(View v) { 
    Intent intent = new Intent(Intent.ACTION_SEND); 
    intent.setType("image/jpeg"); 
    intent.putExtra(Intent.EXTRA_STREAM, [image URI]); 
    startActivity(Intent.createChooser(intent, "Share image with")); 
    } 
} 

下面我都当上取出的代码。

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.ac_image_pager);

    getSupportActionBar().setSelectedNavigationItem(1);

如果有人能够帮助这将是伟大的！

这为u如何在绘制得到的URI的图像：

Uri path = Uri.parse("android.resource://your.package.name/" + R.drawable.your_image);
