1、申請權(quán)限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.CAMERA" />

java

private static final String[] authBaseArr = {//申請類型Manifest.permission.CAMERA,Manifest.permission.WRITE_EXTERNAL_STORAGE }; private static final int authBaseRequestCode = 1; private boolean hasBasePhoneAuth() {PackageManager pm = getPackageManager();for (String auth : authBaseArr) {if (pm.checkPermission(auth, getPackageName()) != PackageManager.PERMISSION_GRANTED) {return false;}}return true; }private void initNavi() {// 申請權(quán)限if (android.os.Build.VERSION.SDK_INT >= 23) {if (!hasBasePhoneAuth()) {this.requestPermissions(authBaseArr, authBaseRequestCode);return;}} }

2、開始起調(diào)相機(jī)

?

private static final int REQUEST_PERMISSION_CODE = 101; private String SAVE_PIC_PATH = Environment.getExternalStorageState().equalsIgnoreCase(Environment.MEDIA_MOUNTED)? Environment.getExternalStorageDirectory().getAbsolutePath() : "/mnt/sdcard";//private String SAVE_REAL_PATH = SAVE_PIC_PATH + "/good/savePic";//保存的確 private String ends = ""; Intent intent = new Intent();// 指定開啟系統(tǒng)相機(jī)的Actionintent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);//圖片intent.addCategory(Intent.CATEGORY_DEFAULT);//圖片 // intent.setAction("android.media.action.VIDEO_CAPTURE");//視頻 // intent.addCategory("android.intent.category.DEFAULT");//視頻// 根據(jù)文件地址創(chuàng)建文件String subForder = SAVE_REAL_PATH;File foder = new File(subForder);if (!foder.exists()) foder.mkdirs();File file = new File(subForder, System.currentTimeMillis() + ".png");//圖片 // File file = new File(subForder, System.currentTimeMillis() + ".mp4");//視頻ends = file.getPath();if (file.exists()) {file.delete();}// 把文件地址轉(zhuǎn)換成Uri格式Uri uri = Uri.fromFile(file);// 設(shè)置系統(tǒng)相機(jī)拍攝照片完成后圖片文件的存放地址intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);startActivityForResult(intent, REQUEST_PERMISSION_CODE);

3、保存圖片

調(diào)用EXTRA_OUTPUT時(shí)，已經(jīng)保存了圖片到文件夾——只是相冊不可見

如需相冊可見，自定義保存即可

public void saveBitmapFile(Bitmap bitmap) {File file = new File(ends);//將要保存圖片的路徑try {BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);bos.flush();bos.close(); // FileOutputStream fos = new FileOutputStream(file); // bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos); // fos.flush(); // fos.close();Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);Uri uri = Uri.fromFile(file);intent.setData(uri);this.sendBroadcast(intent);} catch (IOException e) {e.printStackTrace();}}
