【问题描述】：

我想在图像视图上添加点击事件。通过单击 On Image View 它应该会打开一个适用于 android 的相机。

    ImageView imageView = (ImageView) findViewById(R.id.ImageView1);
    imageView.setImageResource(R.drawable.camera);

【问题讨论】：

Button Click Listeners in Android的可能重复

【参考方案1】：

    imageView = (ImageView) findViewById(R.id.ImageView1);
    imageView.setOnClickListener(new View.OnClickListener() 
        @Override
        public void onClick(View v) 
            Intent imageLoader = (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT)
                    ? new Intent(MediaStore.ACTION_IMAGE_CAPTURE_SECURE)
                    : new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(imageLoader, 1);
        
    );

处理请求：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 

    if (resultCode == RESULT_OK)
        switch (requestCode) 
            case 1:
                your_image_container_to_set_image.setImageBitmap((Bitmap) data.getExtras().get("data"));  //use this if you trying to set image on Imageview

                break;
       
     
   

您可能需要使用Permission：

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

【参考方案2】：

File file;

 imageView = (ImageView) findViewById(R.id.ImageView1);
    imageView.setOnClickListener(new View.OnClickListener() 
        @Override
        public void onClick(View v) 
            takePicture(v);
        
    );
public void takePicture(View view) 
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                file = Uri.fromFile(getOutputMediaFile());
                intent.putExtra(MediaStore.EXTRA_OUTPUT, file);

                startActivityForResult(intent, 100);
            

            @Override
            protected void onActivityResult(int requestCode, int resultCode, Intent data) 
                if (requestCode == 100) 
                    if (resultCode == RESULT_OK) 
                        imageView.setImageURI(file);
                    
                
            


        private static File getOutputMediaFile()
            File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
                    Environment.DIRECTORY_PICTURES), "CameraDemo");

            if (!mediaStorageDir.exists())
                if (!mediaStorageDir.mkdirs())
                    return null;
                
            

            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
            return new File(mediaStorageDir.getPath() + File.separator +
                        "IMG_"+ timeStamp + ".jpg");
