Android拍照，剪切，并放入SD卡

1.首先点击事件中启动拍照，这里写死了图片的名称。实际上可以通过在公用的类中定义一个静态变量来操作。

public void tackPhoto() {   String status = Environment.getExternalStorageState();   if (status.equals(Environment.MEDIA_MOUNTED)) {    try {     File filePath = Environment.getExternalStorageDirectory();     Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);      File f = new File(filePath, "test.jpg");      Uri u = Uri.fromFile(f);      intent.putExtra(MediaStore.Images.Media.ORIENTATION, 0);      intent.putExtra(MediaStore.EXTRA_OUTPUT, u);      startActivityForResult(intent, FLAG_CHOOSE_PHONE);     } catch (ActivityNotFoundException e) {      e.printStackTrace();     }    }   }

@Override         protected void onActivityResult (int requestCode, int resultCode, Intent data) {               if (resultCode == RESULT_OK) {                    File filePath = Environment.getExternalStorageDirectory();                    File f = new File(filePath, "test.jpg");                     if (requestCode == FLAG_CHOOSE_PHONE) {                          Toast. makeText( this, "FLAG_CHOOSE_PHONE", Toast.LENGTH_SHORT )                                      .show();                          String path = f.getAbsolutePath();                          Intent intent = new Intent();                          intent.setAction( "com.android.camera.action.CROP" );                          intent.setDataAndType(Uri. fromFile( newFile(path)), "image/*" );// mUri是已经选择的图片 Uri                          intent.putExtra( "crop", "true");                          intent.putExtra( "aspectX", 3); // 裁剪框比例                          intent.putExtra( "aspectY", 3);                          intent.putExtra( "outputX", 150); // 输出图片大小                          intent.putExtra( "outputY", 150);                          intent.putExtra( "return-data", true);                          startActivityForResult(intent,FLAG_CROP_PHONE);                    } else if (requestCode == FLAG_CROP_PHONE) {                          Bitmap bmap = data.getParcelableExtra( "data");                           if (bmap != null) {                                 try {                                      bmap.compress(Bitmap.CompressFormat. JPEG, 0,                                                   newFileOutputStream(f));                                } catch (FileNotFoundException e) {                                      e.printStackTrace();                                }                          }                    }              }        }
