随时随地选择自己喜欢的图片玩拼图益智游戏
本教程实现拼图,并且可以选择图片的来源,通过摄像头照相获得,也可以通过本地文件夹获得。
废话不多说,请看下面主要代码讲述:
为了使各种大小的图片都能使用,需要对图片进行缩放:
// 缩放图片 public void scaleImage(float w) { int bw = bmpResources.getWidth(); int bh = bmpResources.getHeight(); float scaleW = w / bw; float scaleH = w / bh; Matrix matrix = new Matrix(); if (scaleH > scaleW) { matrix.postScale(scaleW, scaleW); } else { matrix.postScale(scaleH, scaleH); } bmpResources = Bitmap.createBitmap(bmpResources, 0, 0, bw, bh, matrix, true); }
一块完整的图片需要将其分成n*n等份:
// 将图片分割 private void initPuzzleLayout() { setPatchHightAndWidth(); puzzleId = new ArrayList<Map<String, Object>>(); puzzleIndex = new int[rows * cols]; imageOrder = new int[rows * cols]; // 保存碎片的ID for (int i = 0; i < rows; i++) { Map<String, Object> map = new HashMap<String, Object>(); Bitmap bmp; for (int j = 0; j < cols; j++) { map = new HashMap<String, Object>(); bmp = Bitmap.createBitmap(bmpResources, j * ConstValue.width, i * ConstValue.height, ConstValue.width, ConstValue.height); map.put("Id", (i * rows + j)); puzzleIndex[i * rows + j] = i * rows + j; map.put("image", bmp); puzzleId.add(map); } } for (int i = 0; i < imageOrder.length; i++) { imageOrder[i] = puzzleIndex[i]; } }
对用户ontouch事件的处理:
@Override public boolean onTouch(View v, MotionEvent event) { if (touchable) { if (MotionEvent.ACTION_DOWN == event.getAction()) { for (int i = 0; i < rows; i++) { for (int j = 0; j < cols; j++) { if (v == imagesArray[i][j]) { first = second; second = System.currentTimeMillis(); if (second - first <= 500) { // 第一次时间、第二次时间清空 first = 0; second = 0; imagesArray[blankRow][blankCol] .setImageBitmap(btmpArray[i][j]); imagesArray[i][j] .setImageBitmap(btmpArray[blankRow][blankCol]); Bitmap tempBmp = btmpArray[blankRow][blankCol]; btmpArray[blankRow][blankCol] = btmpArray[i][j]; btmpArray[i][j] = tempBmp; int tempInt = result[i * rows + j]; result[i * rows + j] = result[blankRow * rows + blankCol]; result[blankRow * rows + blankCol] = tempInt; isWin = true; isComplete(); } blankRow = i; blankCol = j; } } } } } return false; }
当用户看到自己喜欢的一幕,想拍摄下来玩拼图,调用摄像头代码如下:
Intent intent1 = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); mContext.startActivityForResult(intent1, 1);
调用本地文件夹,浏览本地文件选择图片:
// 初始化路径列表 private void initList() { fileList = new ArrayList<Folder>(); if (Environment.getExternalStorageState().equals( Environment.MEDIA_MOUNTED)) { // 存在SD卡 File path = Environment.getExternalStorageDirectory(); path.getPath(); sdPath = path.getPath(); Folder sdFolder = new Folder(); sdFolder.setFileName(path.getName()); sdFolder.setFilePath(path.getPath()); fileList.add(sdFolder); } // 创建 工程目录文件 fileList = FileManager.getFileList("/"); // 初始化适配器 filePathAdapter = new FilePathAdapter(this, fileList); ((FilePathAdapter) filePathAdapter).superListView = null; fileListView.setAdapter(filePathAdapter); MyListView.superAdapter = filePathAdapter; filePath = null; }
// 初始化界面元件 private void initialView() { title_path = (TextView) findViewById(R.id.titlePath); backPath = (ImageView) findViewById(R.id.infoback01); backPath.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if (filePath != null && filePath.lastIndexOf("/") > 0 && !filePath.equals("/data/data/com.WeatherDemo3") && !filePath.equals(sdPath)) { String fatherPath = filePath.substring(0, filePath .lastIndexOf("/")); curAdpter.fileList = FileManager.getFileList(fatherPath); curAdpter.notifyDataSetChanged(); filePath = fatherPath; title_path.setText(filePath); } else if (filePath != null && filePath.lastIndexOf("/") == 0 && !filePath.equals("/data/data/com.WeatherDemo3") && !filePath.equals(sdPath)) { initList(); filePathAdapter.notifyDataSetChanged(); title_path.setText("/"); filePath = null; } else { Bundle bundle = new Bundle(); Intent it = new Intent(); bundle.putString("newPath", "no"); // it.putExtra("added", "no"); it.putExtras(bundle); setResult(2, it); finish(); } } }); ok = (ImageView) findViewById(R.id.infopreview01); ok.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if (filePath != null) { Intent intent = new Intent(); intent.putExtra("OpenFile", filePath); setResult(0, intent); String str = filePath.substring( filePath.lastIndexOf(".") + 1, filePath.length()); if (str.equals("jpg") || str.equals("png")) { showDialog(1); } else { Toast.makeText(FileBrowserActivity.this, "请选择正确的图片格式", Toast.LENGTH_SHORT).show(); } } else { setResult(2); } } }); fileListView = (ListView) findViewById(R.id.file_list); }
由于附件过大,上传不成功,所以我删去了图片声音文件,但是其中包含所有代码部分,需要的地方请参考,谢谢各位支持!
