我想弄明白这里是错的，我正在为用户建立一个表单，以便能够上传个人资料图片。当点击按钮它会把你带到Android图库（想要让用户在那里拍照），但一旦图片被选中，应用程序崩溃不知道为什么，但我认为错误指向与下面getRealPathFromURI（currImageURI）方法我已经尝试寻找不同的解决方案，但他们似乎显示了如何做到这一点同样的反应...喜欢这个How to get the Full file path from URI http://monstercoda.wordpress.com/2012/04/15/android-image-upload-tutorial-part-i/创建图片上传的Android问题
代码：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == RESULT_OK) {
if(requestCode == 1) {
Uri currImageURI = data.getData();
Log.d("The path","Current image path is ---->" + getRealPathFromURI(currImageURI));
TextView tv_path = (TextView) findViewById(R.id.path);
tv_path.setText(getRealPathFromURI(currImageURI));
}
}
}
public String getRealPathFromURI(Uri contentUri) {
String res = null;
String[] proj={MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(contentUri,proj, null, null, null);
if(cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
res = cursor.getString(column_index);
}
cursor.close();
return res;
}
错误：
