friend ，点击按钮我打开相机拍照，我拍照成功，现在点击图片后只有两个选项，“保存”和“丢弃”，没有任何附加相机点击图像的选项那么如何在下一个 View 中附加图像和显示图像呢？
我的代码是...
public void function2(int id){
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST||requestCode == SELECT_PICTURE) {
try{
try{
selectedImageUri = data.getData();
//OI FILE Manager
String filemanagerstring = selectedImageUri.getPath();
//MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
//DEBUG PURPOSE - you can delete this if you want
if(selectedImagePath!=null){
Intent i=new Intent(MainMenu.this,Imageprview.class);
startActivity(i);
System.out.println(selectedImagePath);
}
else
System.out.println("selectedImagePath is null");
if(filemanagerstring!=null)
System.out.println(filemanagerstring);
else System.out.println("filemanagerstring is null");
//NOW WE HAVE OUR WANTED STRING
if(selectedImagePath!=null)
System.out.println("selectedImagePath is the right one for you!");
else
System.out.println("filemanagerstring is the right one for you!");
}catch (NullPointerException e) {
// TODO: handle exception
} }catch (ArrayIndexOutOfBoundsException e) {
// TODO: handle exception
} }
}
//UPDATED!
public String getPath(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if(cursor!=null)
{
//HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
//THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
else return null;
}
最佳答案
Button btnCam=(Button)findViewById(R.id.camBtn);
btnCam.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Intent detailActivity = new Intent(getBaseContext(),com.rodasys.profile.detailProfile.class);
//startActivity(detailActivity);
saveImage();
} });
}
public void saveImage()
{
try {
FileOutputStream fos = openFileOutput("MyFile.jpeg", Context.MODE_WORLD_WRITEABLE);
fos.close();
File f = new File(getFilesDir() + File.separator + "MyFile.jpeg");
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
intent.putExtra(MediaStore.EXTRA_SCREEN_ORIENTATION,90);
startActivityForResult(intent,IMAGE_CAPTURE);
//startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE).putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f)),IMAGE_CAPTURE);
}
catch(IOException e) {
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 0) {
if (resultCode == RESULT_OK){
finish();
//imageView=(ImageView)findViewById(R.id.imageView1);
//imageView.setImageURI(imageUri);
Intent detActivity = new Intent(getBaseContext(),com.rodasys.profile.detailProfile.class);
startActivity(detActivity);
//Log.d("ANDRO_CAMERA","Picture taken!!!");
//
}
}
}
详细介绍 Activity
公共(public)类 detailProfile 扩展 Activity{
String fname=new File(getFilesDir(),"MyFile.jpeg").getAbsolutePath();
//使用此文件路径您可以在此 Activity 中加载图像
您还有另一个选择，您可以在创建新 Intent 时通过 Intent 传递图像，之后您可以通过新 Intent 中的 Bundle 对象访问该图像。
bytes[] imgs = ...//你的图片 Intent intent = new Intent(this, YourActivity.class); intent.putExtra("img", imgs); 启动 Activity ( Intent )
详细简介
bytes[] receiver = getIntent().getExtra("imgs");
//使用字节数组你可以在你的 ImageView 中显示你的图像
关于android - 从相机拍摄图像后图像附加选项不出现，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7567328/
