我是android deveoper。我需要帮助，我尝试从相机拍照，我得到照片，以及如何添加画廊视图。如何可能吗？我的代码在下面!! enter code here
谢谢！
send_zoo_btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String base64string = "";
// bitmap = i.getDrawingCache();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
ImageByte = stream.toByteArray();
base64string = Base64.encodeBytes(ImageByte);
db.execSQL("insert into newanimal(path,selece_animal) values('"
+ base64string + "','" + id + "' )");
Toast.makeText(ThirdActivity.this, "Data inserted", 1).show();
Intent intent = new Intent().setClass(ThirdActivity.this,
ZoobuzzActivity.class);
startActivity(intent);
}
});
}

答案 0 :(得分：0)
使用
调用相机意图Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, PICK_IMAGE_FROM_CAMERA);
@Override
protected void onActivityResult(int requestCode , int resultCode ,
Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode) {
case PICK_IMAGE_FROM_CAMERA:
Uri uri = data.getData();
imageview.setImageURI(uri);
break;
}
}
}
将图像保存在特定位置的SD卡上
if (uri != null) {
String SD_Card_Path = Environment.getExternalStorageDirectory()
.toString();
String Our_Path = SD_Card_Path + "/NewFolder/Images/";
OutputStream fOut = null;
ImageFullName = Image_Name + "_" + System.currentTimeMillis()
+ ".jpg";
File file = new File(Our_Path + ImageFullName);
try {
fOut = new FileOutputStream(file);
Bitmap mBitmap = null;
mBitmap = Media.getBitmap(this.getContentResolver(),
myCaptureUri);
mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
fOut.flush();
fOut.close();
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
