Android摄像头意图 [英] Android camera intent

问题描述

我要推的意图，默认的摄像头应用程序，使其拍照，保存并返回一个URI。有没有办法做到这一点？

解决方案

 私有静态最终诠释TAKE_PICTURE = 1;
私人乌里imageUri;

公共无效takePhoto（查看视图）{
    意向意图=新的意图（android.media.action.IMAGE_CAPTURE）;
    档案照片=新的文件（Environment.getExternalStorageDirectory（），Pic.jpg）;
    intent.putExtra（MediaStore.EXTRA_OUTPUT，
            Uri.fromFile（照片））;
    imageUri = Uri.fromFile（照片）;
    startActivityForResult（意向，TAKE_PICTURE）;
}

@覆盖
公共无效onActivityResult（INT申请code，INT结果code，意图数据）{
    super.onActivityResult（要求code，因此code，数据）;
    开关（要求code）{
    案例TAKE_PICTURE：
        如果（结果code == Activity.RESULT_OK）{
            乌里selectedImage = imageUri;
            。getContentResolver（）有NotifyChange（selectedImage，NULL）;
            ImageView的ImageView的=（ImageView的）findViewById（R.id.ImageView）;
            ContentResolver的CR = getContentResolver（）;
            点阵位图;
            尝试 {
                 位= android.provider.MediaStore.Images.Media
                 .getBitmap（CR，selectedImage）;

                imageView.setImageBitmap（位）;
                Toast.makeText（这一点，selectedImage.toString（）
                        Toast.LENGTH_LONG）.show（）;
            }赶上（例外五）{
                Toast.makeText（这一点，无法加载，Toast.LENGTH_SHORT）
                        。显示（）;
                Log.e（相机，e.toString（））;
            }
        }
    }
}
 

I need to push an intent to default camera application to make it take a photo, save it and return an URI. Is there any way to do this?

解决方案

private static final int TAKE_PICTURE = 1;    
private Uri imageUri;

public void takePhoto(View view) {
    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    File photo = new File(Environment.getExternalStorageDirectory(),  "Pic.jpg");
    intent.putExtra(MediaStore.EXTRA_OUTPUT,
            Uri.fromFile(photo));
    imageUri = Uri.fromFile(photo);
    startActivityForResult(intent, TAKE_PICTURE);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
    case TAKE_PICTURE:
        if (resultCode == Activity.RESULT_OK) {
            Uri selectedImage = imageUri;
            getContentResolver().notifyChange(selectedImage, null);
            ImageView imageView = (ImageView) findViewById(R.id.ImageView);
            ContentResolver cr = getContentResolver();
            Bitmap bitmap;
            try {
                 bitmap = android.provider.MediaStore.Images.Media
                 .getBitmap(cr, selectedImage);

                imageView.setImageBitmap(bitmap);
                Toast.makeText(this, selectedImage.toString(),
                        Toast.LENGTH_LONG).show();
            } catch (Exception e) {
                Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
                        .show();
                Log.e("Camera", e.toString());
            }
        }
    }
}
