在我的应用程序中,我使用
Android设备相机捕获我的图像.在某些设备上它工作正常,但不是全部,我只是测试了LG nexus 5 E960,在我捕获图像后它总是结束崩溃而无法保存结果这是我的代码：
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent,1);
protected void onActivityResult(int requestCode,int resultCode,Intent returnimage) {
super.onActivityResult(requestCode,resultCode,returnimage);
switch (requestCode) {
case 1:
if (resultCode == RESULT_OK) {
Uri selectedImage = returnimage.getData();
String stringUri;
stringUri = selectedImage.toString();
Intent i1 = new Intent(MainActivity.this,Secondpage.class);
i1.putExtra("Stringuri",stringUri );
startActivity(i1);
}
break;
我的logcat是：
java.lang.RuntimeException: Failure delivering result ResultInfo{who=null,request=1,result=-1,data=Intent { act=inline-data (has extras) }} to activity

解决方法
使用像
@Override
protected void onActivityResult(int requestCode,Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
Intent i1 = new Intent(MainActivity.this,Secondpage.class);
i1.putExtra("bitmap",imageBitmap );
startActivity(i1);
}
}
并在Secondpage活动中
得到像这样的图像
Bitmap bitimage = getIntent().getParcelableExtra("bitmap");
your_image+_view.setimageBitmap(bitimage);
