从相机捕获图像,并在android中进行固定裁剪
问题描述:
我试图裁剪图像,因为我们正在做Facebook。我在我的应用程序中使用了这个链接:https://github.com/oginotihiro/cropview这对我来说工作正常。但在这里,当我点击一个按钮时,它直接去画廊和裁剪选定的图像。而不是我想打开我的设备中的相机,然后单击形象和我想剪裁。我该怎么做呢?有人可以帮助我。从相机捕获图像,并在android中进行固定裁剪
我试过这个code.But我无法实现。
imageBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
reset();
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_PICK);
}
});
doneBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
final ProgressDialog dialog = ProgressDialog.show(StudentDetails.this, null, "Please wait…", true, false);
cropView.setVisibility(View.GONE);
layout4.setVisibility(View.GONE);
resultIv.setVisibility(View.VISIBLE);
layout3.setVisibility(View.GONE);
layoutUpload.setVisibility(View.VISIBLE);
// editTextName.setVisibility(View.GONE);
buttonUpload.setVisibility(View.VISIBLE);
new Thread() {
public void run() {
croppedBitmap = cropView.getOutput();
runOnUiThread(new Runnable() {
@Override
public void run() {
// cropped image set
resultIv.setImageBitmap(croppedBitmap);
}
});
Uri destination = Uri.fromFile(new File(getCacheDir(), "cropped"));
CropUtil.saveOutput(StudentDetails.this, destination, croppedBitmap, 1);
runOnUiThread(new Runnable() {
@Override
public void run() {
dialog.dismiss();
}
});
}
}.start();
}
});
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK && requestCode == REQUEST_PICK) {
filePath = data.getData();
cropView.setVisibility(View.VISIBLE);
layoutImage.setVisibility(View.VISIBLE);
layout3.setVisibility(View.GONE);
layout4.setVisibility(View.VISIBLE);
textNameVal.setVisibility(View.GONE);
text1.setVisibility(View.GONE);
buttonUpload.setVisibility(View.GONE);
int x=(int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 100, getResources().getDisplayMetrics());
int y=(int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 100, getResources().getDisplayMetrics());
cropView.of(filePath).withAspect(x,y).initialize(StudentDetails.this);
}
}

第一步:启动开画廊
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
第二步:从库获取图像:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
随着你的情况,你可以在onActivityResult方法裁剪。 它会帮助你。

谢谢你的答复。我已经试过这段代码。但我想从摄像头捕获照片。这与我所做的相同,即从gallery中选择。我想在意图中使用ACTION_IMAGE_CAPTURE。 – Amshu

随着相机: 第一步:打开相机
/*
* Capturing Camera Image will lauch camera app requrest image capture
*/
private void captureImage() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
第二步:从摄像机获取图像。
/**
* Receiving activity result method will be called after closing the camera
* */
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// if the result is capturing Image
if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// successfully captured the image
// display it in image view
previewCapturedImage();
} else if (resultCode == RESULT_CANCELED) {
// user cancelled Image capture
Toast.makeText(getApplicationContext(),
"User cancelled image capture", Toast.LENGTH_SHORT)
.show();
} else {
// failed to capture image
Toast.makeText(getApplicationContext(),
"Sorry! Failed to capture image", Toast.LENGTH_SHORT)
.show();
}
}
}
第三步:添加权限
<!-- Accessing camera hardware -->
<uses-feature android:name="android.hardware.camera" />
对此有任何解决方案。由于我刚接触android,因此无法做到这一点。 – Amshu
