Android 如何访问内部存储的图像
我有一个应用程序,它可以拍摄照片并将照片存储在我创建的文件夹中。拍完一张照片后,我希望能够访问它,以便通过电子邮件发送。如何访问我刚刚拍摄的图像?以下是我在拍摄后在内部保存图像的代码:Android 如何访问内部存储的图像,android,android-intent,android-image,Android,Android Intent,Android Image,我有一个应用程序,它可以拍摄照片并将照片存储在我创建的文件夹中。拍完一张照片后,我希望能够访问它,以便通过电子邮件发送。如何访问我刚刚拍摄的图像?以下是我在拍摄后在内部保存图像的代码: protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (resultCode
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

if (resultCode == RESULT_OK) {
Bundle extras = data.getExtras();

iv.setImageBitmap(bmp);
File storagePath = new File(
Environment.getExternalStorageDirectory() + "/DavePics/");
storagePath.mkdirs();
File myImage = new File(storagePath, Long.toString(System
.currentTimeMillis()) + ".jpg");
Bitmap b = Bitmap.createScaledBitmap(bmp, 320, 480, false);
try {
FileOutputStream out = new FileOutputStream(myImage);
b.compress(Bitmap.CompressFormat.JPEG, 80, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
当我检查我创建的文件夹时,图片就在那里。我现在想做的是访问该图片,以便我可以通过电子邮件从下面的代码发送它:
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.bSendPic:
String emailaddress[] = { "info@sklep.com", "", };
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.putExtra(Intent.EXTRA_EMAIL, emailaddress);
//emailIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, pic);
emailIntent.setType("image/jpeg");
startActivity(Intent.createChooser(emailIntent, "Send Mail"));
break;
case R.id.ibTakePic:
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, cameraData);
break;
}
}
如何访问此图片,以便将其添加到电子邮件中?我这样做对吗?谢谢
编辑:这是我的全部代码
public class Camera extends Activity implements View.OnClickListener {
ImageButton ib;
Button b;
ImageView iv;
Intent i;
final static int cameraData = 0;
Bitmap bmp;
File myImage;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.photo);
initialize();
InputStream is = getResources().openRawResource(R.drawable.ic_launcher);
bmp = BitmapFactory.decodeStream(is);
}
private void initialize() {
ib = (ImageButton) findViewById(R.id.ibTakePic);
b = (Button) findViewById(R.id.bSendPic);
iv = (ImageView) findViewById(R.id.ivReturnedPic);
b.setOnClickListener(this);
ib.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.bSendPic:
if (myImage.exists()) {
String emailaddress[] = { "info@sklep.com", "", };
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.putExtra(Intent.EXTRA_EMAIL, emailaddress);
emailIntent.setType("image/jpeg");
emailIntent
.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(myImage));
startActivity(Intent.createChooser(emailIntent, "Send Mail"));
}
break;
case R.id.ibTakePic:
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, cameraData);
break;
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
bmp = (Bitmap) extras.get("data");
iv.setImageBitmap(bmp);
File storagePath = new File(
Environment.getExternalStorageDirectory() + "/DavePics/");
storagePath.mkdirs();
myImage = new File(storagePath, Long.toString(System
.currentTimeMillis()) + ".jpg");
Bitmap b = Bitmap.createScaledBitmap(bmp, 320, 480, false);
try {
FileOutputStream out = new FileOutputStream(myImage);
b.compress(Bitmap.CompressFormat.JPEG, 80, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
您忘记的代码行是
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(myImage));
在代码中,在活动中全局声明File myImage
现在在电子邮件发送代码
检查文件是否存在
if(myImage.exist())
{
String emailaddress[] = { "info@sklep.com", "", };
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.putExtra(Intent.EXTRA_EMAIL, emailaddress);
emailIntent.setType("image/jpeg");
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(myImage));
startActivity(Intent.createChooser(emailIntent, "Send Mail"));
}
谢谢我这样做,当我去发送电子邮件时,你可以看到附件已经添加。然而,当我发送电子邮件时,它只是说发送电子邮件,然后它就再也不发送了。我已附上我的完整代码。有什么想法吗?我知道这是可行的。万分感谢!我的gmail帐户一直冻结,但一旦我清除缓存并重新启动它,它就工作得很好!欢迎你,伙计。。!快乐的编码。。!
