android从相册或者照相获取图片，并且进行裁切

先声明一点变量

	private AlertDialog dialog;
	private static final int PHOTO_REQUEST_TAKEPHOTO = 1;
	private static final int PHOTO_REQUEST_GALLERY = 2;
	private static final int PHOTO_REQUEST_CUT = 3;
	File tempFile = new File(Environment.getExternalStorageDirectory(),
			getPhotoFileName());
	private int crop = 180;

一个简单的点击事件不多说了

<span style="font-size:14px;">personDetailsHeadImg = (ImageButton) findViewById(R.id.person_details_head_img);//用于显示获取的图片</span>

<span style="font-size:14px;">personHeadRela = (RelativeLayout) findViewById(R.id.person_head_rela);//点击开始选择相册还是照相
personHeadRela.setOnClickListener(new onlistener());</span>

我这里是用一个对话框来选择是相册还是照相

			case R.id.person_head_rela:
				if (dialog == null) {
					dialog = new AlertDialog.Builder(PersonDetailsActivity.this).setItems(new String[] { "相机", "相册" },
									new DialogInterface.OnClickListener() {
										@Override
										public void onClick(DialogInterface dialog,int which) {
											if (which == 0) {
												//调用系统的照相机程序
												Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
												intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(tempFile));
												startActivityForResult(intent,PHOTO_REQUEST_TAKEPHOTO);
											} else {
												//调用系统的相册
												Intent intent = new Intent(Intent.ACTION_PICK,null);
												intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,"image/*");
												startActivityForResult(intent,PHOTO_REQUEST_GALLERY);
											}
										}
									}).create();
				}
				if (!dialog.isShowing()) {
					dialog.show();
				}
				break;

从onActivityResult中来接受回调的图片

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		// TODO Auto-generated method stub

		switch (requestCode) {
		case PHOTO_REQUEST_TAKEPHOTO:
			startPhotoZoom(Uri.fromFile(tempFile), 150);
			break;

		case PHOTO_REQUEST_GALLERY:
			if (data != null)
				startPhotoZoom(data.getData(), 150);
			break;

		case PHOTO_REQUEST_CUT:
			if (data != null)
				setPicToView(data);
			break;
		}
		super.onActivityResult(requestCode, resultCode, data);

	}</span>

下面把图片进行处理裁切，给图片取个名字

<span style="font-size:14px;">	private void startPhotoZoom(Uri uri, int size) {
		Log.e("zoom", "begin");
		Intent intent = new Intent("com.android.camera.action.CROP");//调用系统提供的裁切
		intent.setDataAndType(uri, "image/*");
		intent.putExtra("crop", "true");
		intent.putExtra("aspectX", 1);// 裁剪框比例
		intent.putExtra("aspectY", 1);
		intent.putExtra("outputX", crop);// 输出图片大小
		intent.putExtra("outputY", crop);
		intent.putExtra("return-data", true);
		startActivityForResult(intent, PHOTO_REQUEST_CUT);
	}

	private void setPicToView(Intent picdata) {
		Bundle bundle = picdata.getExtras();
		if (bundle != null) {
			Bitmap photo = bundle.getParcelable("data");
			Drawable drawable = new BitmapDrawable(photo);
			personDetailsHeadImg.setBackgroundDrawable(drawable);
		}
	}

	private String getPhotoFileName() {
		Date date = new Date(System.currentTimeMillis());
		SimpleDateFormat dateFormat = new SimpleDateFormat(
				"'IMG'_yyyyMMdd_HHmmss");
		return dateFormat.format(date) + ".jpg";
	}</span>

就这样大功告成！
