Android之拍照和相册选取图片并裁剪得到路径

-----------------转载请注明出处：http://blog.csdn.net/android_cll

一：先来两张效果图：

1.这是我们项目用到这个功能的截图、

关于这个裁剪后的图片怎么变圆形头像的问题我这篇文章有介绍：http://blog.csdn.net/android_cll/article/details/54574778

2.demo的截图，功能和上面截图功能一样，懒得截图、

二：实现步骤：

1.xml的实现、

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

            android:id="@+id/logo"
        android:layout_width="114dp"
        android:layout_height="114dp"
        android:layout_centerInParent="true"
        android:src="@mipmap/ic_launcher" />

    <RelativeLayout
        android:id="@+id/relative_logo"
        android:layout_width="280dp"
        android:layout_height="50dp"
        android:layout_below="@+id/logo"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="20dp"
        android:background="@drawable/tankuan">

                    android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:text="点击拍照或选择相册"
            android:textColor="#fff"
            android:textSize="16dp" />
    RelativeLayout>

RelativeLayout>

2.activity的实现、

package cll.com.myapplication;

import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.view.View;
import android.widget.ImageView;
import android.widget.RelativeLayout;

import java.io.File;

/**
 * Created by Administrator on 2017/3/28.
 * 拍照和相册选取图片并裁剪得到图片路径和图片显示
 */
public class PhotoShoot extends Activity implements View.OnClickListener {

    private ImageView logo;//图片
    private RelativeLayout relative_logo;//点击拍照或者选择相册图片
    private String urlpath;//图片路径

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.photoshoot_layout);
        initlayout();
    }

    /**
     * 实例化
     */
    private void initlayout() {
        logo = (ImageView) findViewById(R.id.logo);
        relative_logo = (RelativeLayout) findViewById(R.id.relative_logo);
        relative_logo.setOnClickListener(this);
    }

    /**
     * 点击事件
     *
     * @param view
     */
    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.relative_logo:
                new ActionSheetDialog(PhotoShoot.this)
                        .builder()
                        .setCancelable(true)
                        .setCanceledOnTouchOutside(true)
                        .addSheetItem("相册",
                                ActionSheetDialog.SheetItemColor.Blue,
                                new ActionSheetDialog.OnSheetItemClickListener() {

                                    @Override
                                    public void onClick(int which) {

                                        Intent intent = new Intent(Intent.ACTION_PICK, null);
                                        intent.setDataAndType(
                                                MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                                                "image/*");
                                        startActivityForResult(intent, 1);
                                    }
                                })
                        .addSheetItem("拍照",
                                ActionSheetDialog.SheetItemColor.Blue,
                                new ActionSheetDialog.OnSheetItemClickListener() {

                                    @Override

3.路径获取工具类、

package cll.com.myapplication;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.CompressFormat;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;

public class FileUtilcll {

    /**
     * 将Bitmap 图片保存到本地路径，并返回路径
     * @param fileName 文件名称
     * @param bitmap   图片
     * @param资源类型，参照 MultimediaContentType 枚举，根据此类型，保存时可自动归类
     */
    public static String saveFile(Context c, String fileName, Bitmap bitmap) {
        return saveFile(c, "", fileName, bitmap);
    }

    public static String saveFile(Context c, String filePath, String fileName, Bitmap bitmap) {
        byte[] bytes = bitmapToBytes(bitmap);
        return saveFile(c, filePath, fileName, bytes);
    }

    public static byte[] bitmapToBytes(Bitmap bm) {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        bm.compress(CompressFormat.JPEG, 100, baos);
        return baos.toByteArray();
    }

    public static String saveFile(Context c, String filePath, String fileName, byte[] bytes) {
        String fileFullName = "";
        FileOutputStream fos = null;
        String dateFolder = new SimpleDateFormat("yyyyMMddHHmmss", Locale.CHINA)
                .format(new Date());
        try {
            String suffix = "";
            if (filePath == null || filePath.trim().length() == 0) {
                filePath = Environment.getExternalStorageDirectory() + "/XiaoCao/" + dateFolder + "/";
            }
            File file = new File(filePath);
            if (!file.exists()) {
                file.mkdirs();
            }
            File fullFile = new File(filePath, fileName + suffix);
            fileFullName = fullFile.getPath();
            fos = new FileOutputStream(new File(filePath, fileName + suffix));
            fos.write(bytes);

                try {
                    fos.close();
                } catch (IOException e) {
                    fileFullName = "";
                }
            }
        }
        return fileFullName;
    }
}
