[Android Pro] 调用系统相机和图库，裁剪图片
private static final int PHOTO_REQUEST_TAKEPHOTO = 1;// 拍照 private static final int PHOTO_REQUEST_GALLERY = 2;// 从相册中选择 private static final int PHOTO_REQUEST_CUT = 3;// 结果 private File tempFile = new File(Environment.getExternalStorageDirectory(), getPhotoFileName()); protected void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case PHOTO_REQUEST_TAKEPHOTO:// 当选择拍照时调用 startPhotoZoom(Uri.fromFile(tempFile)); break; case PHOTO_REQUEST_GALLERY:// 当选择从本地获取图片时 // 做非空判断，当我们觉得不满意想重新剪裁的时候便不会报异常，下同 if (data != null) { System.out.println("11================"); startPhotoZoom(data.getData()); } else { System.out.println("================"); } break; case PHOTO_REQUEST_CUT:// 返回的结果 if (data != null) // setPicToView(data); sentPicToNext(data); break; } super.onActivityResult(requestCode, resultCode, data); }
// 使用系统当前日期加以调整作为照片的名称 private String getPhotoFileName() { Date date = new Date(System.currentTimeMillis()); SimpleDateFormat dateFormat = new SimpleDateFormat( "'IMG'_yyyyMMdd_HHmmss"); return dateFormat.format(date) + ".jpg"; }
调用系统拍照功能：
Intent cameraintent = new Intent( MediaStore.ACTION_IMAGE_CAPTURE); // 指定调用相机拍照后照片的储存路径 cameraintent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(tempFile)); startActivityForResult(cameraintent, PHOTO_REQUEST_TAKEPHOTO);
调用系统相册功能：
Intent getAlbum = new Intent(Intent.ACTION_GET_CONTENT); getAlbum.setType("image/*"); startActivityForResult(getAlbum, PHOTO_REQUEST_GALLERY);
调用系统裁剪功能：
private void startPhotoZoom(Uri uri) { Intent intent = new Intent("com.android.camera.action.CROP"); intent.setDataAndType(uri, "image/*"); // crop为true是设置在开启的intent中设置显示的view可以剪裁 intent.putExtra("crop", "true"); // aspectX aspectY 是宽高的比例 intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); // outputX,outputY 是剪裁图片的宽高 intent.putExtra("outputX", 300); intent.putExtra("outputY", 300); intent.putExtra("return-data", true); intent.putExtra("noFaceDetection", true); System.out.println("22================"); startActivityForResult(intent, PHOTO_REQUEST_CUT); }
自定义对话框：
mDialog = new AlertDialog.Builder(this, R.style.FullScreenDialog) .create(); if (mDialog != null && !mDialog.isShowing()) { mDialog.show(); mDialog.setContentView(R.layout.dialog_select_imge); mDialog.setCanceledOnTouchOutside(false);
}
自定义style ：
<style name="FullScreenDialog" parent="android:style/Theme.Dialog"> <item name="android:windowNoTitle">true</item> <item name="android:windowFrame">@null</item> <item name="android:windowIsFloating">true</item> <item name="android:windowIsTranslucent">false</item> <item name="android:background">@android:color/transparent</item> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:backgroundDimEnabled">true</item> </style>
