如何存储图像中的应用程序内部存储器,从图库中选择,并通过种植意向后, [英] How to store image in app internal memory, after selecting from gallery and cropping through intent
问题描述
在我的应用我从图库中选择图片,比我冒出的形象,比其存储在外部存储。
但是,如果出现SD卡不超过可用的问题。
所以在这里我问你如何存储图像中的应用程序的内部存储。
下面是我的code用于外部存储。
覆盖
公共无效的onClick(视图v){
INT outputX = 400;
INT outputY = 400;
INT aspectX = 1;
INT aspectY = 1;
意向意图=新意图(Intent.ACTION_GET_CONTENT,NULL);
intent.setType(图像/ *);
intent.putExtra(裁剪,真);
intent.putExtra(aspectX,aspectX);
intent.putExtra(aspectY,aspectY);
intent.putExtra(outputX,outputX);
intent.putExtra(outputY,outputY);
intent.putExtra(规模化,真正的);
intent.putExtra(回归数据,FALSE);
selectedImageUri = getTempUri();
intent.putExtra(MediaStore.EXTRA_OUTPUT,selectedImageUri);
intent.putExtra(OUTPUTFORMAT,Bitmap.Com pressFormat.JPEG.toString());
intent.putExtra(noFaceDetection,真正的); startActivityForResult(意向,2);
}
下面是我如何得到externel文件的URI:
私人乌里getTempUri(){
返回Uri.fromFile(getTempFile());
} 私人文件getTempFile(){
如果(isSDCARDMounted()){ 文件f =新的文件(Environment.getExternalStorageDirectory()
TEMP_PHOTO_FILE);
尝试{
f.createNewFile();
}赶上(IOException异常五){
// TODO自动生成catch块
Toast.makeText(MainActivity.this文件的问题,Toast.LENGTH_LONG)
。显示();
}
返回F;
}其他{
返回null;
} } 私人布尔isSDCARDMounted(){
字符串状态= Environment.getExternalStorageState(); 如果(status.equals(Environment.MEDIA_MOUNTED))
返回true;
返回false;
} @覆盖
保护无效的onActivityResult(INT申请code,INT结果code,意图数据){
super.onActivityResult(要求code,结果code,数据); 如果(要求code == 2){
PATH = selectedImageUri.getPath();
imageView.setImageBitmap(BitmapFactory
由Matchi.com提供回到codeFILE(路径));
}
}
您可以使用的上下文的getCacheDir() 方式来存储应用程序缓存目录中的形象。使用以下code将图像存储缓存目录中。
//这将创建高速缓存目录中的自定义目录
文件cacheDir =新的文件(this.getCacheDir(),Custom_Directory);
如果(!cacheDir.exists())
cacheDir.mkdir();//这会给你的缓存目录的完整路径。您可以使用此为您的文件
this.getCacheDir()。getAbsolutePath()
In my app I am selecting an image from gallery, than I cropped that image, than store it in external storage.
But if sd-card not available than problem occurs.
So here I am asking you how to store image in application internal storage.
Here is my code for external storage.
Override
public void onClick(View v) {
int outputX = 400;
int outputY = 400;
int aspectX = 1;
int aspectY = 1;
Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null);
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("aspectX", aspectX);
intent.putExtra("aspectY", aspectY);
intent.putExtra("outputX", outputX);
intent.putExtra("outputY", outputY);
intent.putExtra("scale", true);
intent.putExtra("return-data", false);
selectedImageUri = getTempUri();
intent.putExtra(MediaStore.EXTRA_OUTPUT, selectedImageUri);
intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
intent.putExtra("noFaceDetection", true);
startActivityForResult(intent, 2);
}
Here is how I get URI of externel file:
private Uri getTempUri() {
return Uri.fromFile(getTempFile());
}
private File getTempFile() {
if (isSDCARDMounted()) {
File f = new File(Environment.getExternalStorageDirectory(),
TEMP_PHOTO_FILE);
try {
f.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
Toast.makeText(MainActivity.this, "file issue", Toast.LENGTH_LONG)
.show();
}
return f;
} else {
return null;
}
}
private boolean isSDCARDMounted() {
String status = Environment.getExternalStorageState();
if (status.equals(Environment.MEDIA_MOUNTED))
return true;
return false;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 2) {
path = selectedImageUri.getPath();
imageView.setImageBitmap(BitmapFactory
.decodeFile(path));
}
}
You can use Context's getCacheDir() method to store your image in application cache directory. Use following code to store your image inside cache directory.
//this will create a custom directory inside cache directory
File cacheDir = new File(this.getCacheDir(), "Custom_Directory");
if (!cacheDir.exists())
cacheDir.mkdir();
//this will give you full path of cache directory. You can use this for your file
this.getCacheDir().getAbsolutePath()
