调用系统相机和相册，并且裁剪成圆形图片(解决6.0，7.0，8.0版本问题)

之前写过一篇博客，那篇博客对7.0手机裁剪图片的问题没有进行解决，现在对之前的那篇博客进行补充，解决了Android6.0，7.0，8.0版本问题，不仅可以调用相册，相机，还可以将图片保存到本地，并且裁剪成圆形图片

必要的权限：

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

在res文件下建一个文件夹xml  xml文件夹下一个文件file_path

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">

    <external-path
        name="external_storage_root"
        path="." />
</paths>

AndroidManifest:

<application
       ...
        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="com.example.jingqian.camera.fileprovider"
            android:grantUriPermissions="true"
            android:exported="false">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_path">
            </meta-data>
        </provider>
    </application>

MainActivity布局：

<ImageButton
        android:id="@+id/iv_head"
        android:layout_width="120dp"
        android:layout_height="120dp"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="10dp"
        android:background="@null"
        android:scaleType="fitXY"
        android:src="@drawable/ic_launcher_background" />

PopupWindow布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

        android:paddingTop="10dip"
        android:text="取消"
        android:textSize="16sp" />

</LinearLayout>

MainAtivity中代码：

   //这是popupWindow中的相册按钮，相机按钮，取消按钮
    private Button btn_picture, btn_photo, btn_cancle;
   //头像控件
    private ImageButton ivHead;

    private Bitmap head;// 头像Bitmap
    @SuppressLint("SdCardPath")
    private static String path = "/sdcard/myHead/";// sd路径
    private Uri imageUri;
    private Uri uri;

onCreate方法：

        DongTaiShare();
        ivHead = (ImageButton) findViewById(R.id.iv_head);
        ivHead.setOnClickListener(this);

       

头像的点击事件里：

        //得到PopupWindow的视图
        View view = getLayoutInflater().inflate(R.layout.photo_choose_dialog, null);
        //给弹框设置样式
        final Dialog dialog = new Dialog(this, R.style.transparentFrameWindowStyle);

        Window window = dialog.getWindow();
        // 设置显示动画
        window.setWindowAnimations(R.style.main_menu_animstyle);
        WindowManager.LayoutParams wl = window.getAttributes();
        wl.x = 0;
        wl.y = getWindowManager().getDefaultDisplay().getHeight();
        // 以下这两句是为了保证按钮可以水平满屏
        wl.width = ViewGroup.LayoutParams.MATCH_PARENT;
        wl.height = ViewGroup.LayoutParams.WRAP_CONTENT;

        // 设置显示位置
        dialog.onWindowAttributesChanged(wl);
        // 设置点击外围解散
        dialog.setCanceledOnTouchOutside(true);
        dialog.show();

        btn_picture = (Button) window.findViewById(R.id.btn_picture);
        btn_photo = (Button) window.findViewById(R.id.btn_photo);
        btn_cancle = (Button) window.findViewById(R.id.btn_cancle);
        btn_picture.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //调用系统相册
                Intent intent1 = new Intent(Intent.ACTION_PICK, null);
                intent1.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");
                startActivityForResult(intent1, 1);
                dialog.dismiss();
            }
        });
        btn_photo.setOnClickListener(new View.OnClickListener() {


            @Override
            public void onClick(View v) {
                //调用系统相机
                Intent intent2 = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                File file = new File(Environment.getExternalStorageDirectory(), "head.jpg");
//判断手机版本号，这里是7.0以上的
                if (Build.VERSION.SDK_INT >= 24) {
                    uri = FileProvider.getUriForFile(MainActivity.this, "com.example.jingqian.camera.fileprovider", file);

                } else {
                    uri = Uri.fromFile(file); //7.0以下
                }


                intent2.putExtra(MediaStore.EXTRA_OUTPUT, uri);
                startActivityForResult(intent2, 5);
                dialog.dismiss();
            }
        });
        btn_cancle.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });

动态权限

private void DongTaiShare() {
        if (Build.VERSION.SDK_INT >= 23) {
            String[] mPermissionList = new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.CALL_PHONE, Manifest.permission.READ_LOGS, Manifest.permission.READ_PHONE_STATE, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.SET_DEBUG_APP, Manifest.permission.SYSTEM_ALERT_WINDOW, Manifest.permission.GET_ACCOUNTS, Manifest.permission.WRITE_APN_SETTINGS, Manifest.permission.CAMERA};
            ActivityCompat.requestPermissions(this, mPermissionList, 123);
        }

    }

在MainActivity中的一些方法

 private void startPhotoZoom(Uri uri) {
        File CropPhoto = new File(getExternalCacheDir(), "Crop.jpg");//这个是创建一个截取后的图片路径和名称。
        try {
            if (CropPhoto.exists()) {
                CropPhoto.delete();
            }
            CropPhoto.createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
        }

        imageUri = Uri.fromFile(CropPhoto);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); //添加这一句表示对目标应用临时授权该Uri所代表的文件
        }
        intent.putExtra("crop", "true");
        intent.putExtra("scale", true);

        intent.putExtra("aspectX", 1);

        canvas.drawBitmap(bitmap, null, rect, p);
        return backgroundBm;
    }

还有点击头像时popupWindow时从下往上滑出的，所以还要添加一些动画，

在res文件下建anim文件夹   文件夹下两个文件photo_dialog_in_anim.xml   和   photo_dialog_out_anim.xml

photo_dialog_in_anim.xml ：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="500"
        android:fromXDelta="0"
        android:fromYDelta="1000"
        android:toXDelta="0"
        android:toYDelta="0" />

</set>

photo_dialog_out_anim.xml：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="500"
        android:fromXDelta="0"
        android:fromYDelta="0"
        android:toXDelta="0"
        android:toYDelta="1000" />

</set>

在style下设置：

<style name="main_menu_animstyle">
        <item name="android:windowEnterAnimation">@anim/photo_dialog_in_anim</item>
        <item name="android:windowExitAnimation">@anim/photo_dialog_out_anim</item>
    </style>

这样就可以完美实现调用相册和相机并且裁剪图片了

May everyone be happy every day and everything go well!
