本文实例为大家分享了AndroID打开相机和相册具体代码，供大家参考，具体内容如下

打开相机 

 /**   * 选择相机   */  private voID showCamera() {    // 跳转到系统照相机    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);    if (cameraIntent.resolveActivity(getPackageManager()) != null) {      // 设置系统相机拍照后的输出路径      // 创建临时文件      mTmpfile = OtherUtils.createfile(getApplicationContext());      cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromfile(mTmpfile));      startActivityForResult(cameraIntent,REQUEST_CAMERA);    } else {      Toast.makeText(getApplicationContext(),R.string.msg_no_camera,Toast.LENGTH_SHORT).show();    }  } 

打开相册

Intent albumIntent = new Intent(Intent.ACTION_PICK,null);    albumIntent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,"image/*");    startActivityForResult(albumIntent,REQUEST_ALBUM_OK); 

onActivityResult 

 @OverrIDe  protected voID onActivityResult(int requestCode,int resultCode,Intent data) {    super.onActivityResult(requestCode,resultCode,data);    switch (requestCode) {      case REQUEST_CAMERA:        //请求相机        if (mTmpfile != null) {          Log.d(TAG,"onActivityResult: 请求相机： " + mTmpfile.getabsolutePath());          Picasso.with(this).load(mTmpfile).centerCrop().resize(OtherUtils.dip2px(this,100),OtherUtils.dip2px(this,100))              .error(R.mipmap.pictures_no).into(mIvdispaly);        }        break;      case REQUEST_ALBUM_OK:        Log.d(TAG,"onActivityResult:相册 " + data.getData().toString());        ContentResolver resolver = getContentResolver();        try {          inputStream inputStream = resolver.openinputStream(data.getData());          Bitmap bitmap = BitmapFactory.decodeStream(inputStream);          mIvdispaly.setimageBitmap(bitmap);        } catch (fileNotFoundException e) {          e.printstacktrace();        }        //        Cursor query = resolver.query(data.getData(),null,null);////        String str = null;//        while (query.movetoNext()) {//          Log.d(TAG,"onActivityResult:数量 " + query.getCount());//          str =query.getString(query.getColumnIndex(MediaStore.Images.Media.DATA));//          Log.d(TAG,"onActivityResult: 列名" + query.getString(query.getColumnIndex(MediaStore.Images.Media.DATA)));//        }//        query.close();//        Picasso.with(this).load(new file(str)).centerCrop().resize(OtherUtils.dip2px(this,100))//            .error(R.mipmap.pictures_no).into(mIvdispaly);        break;    }  } 

OtherUtils 

import androID.content.Context;import androID.os.Environment;import java.io.file;import java.util.Date;/** * Created by 刘楠 on 2016/7/20 0020.22:37 */public class OtherUtils {  public static int dip2px(Context context,float dpValue) {    final float scale = context.getResources().getdisplayMetrics().density;    return (int) (dpValue * scale + 0.5f);  }  public static int px2dip(Context context,float pxValue) {    final float scale = context.getResources().getdisplayMetrics().density;    return (int) (pxValue / scale + 0.5f);  }  /**   * 获取拍照相片存储文件   * @param context   * @return   */  public static file createfile(Context context){    file file;    if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){      String timeStamp = String.valueOf(new Date().getTime());      file = new file(Environment.getExternalStorageDirectory() +          file.separator + timeStamp+".jpg");    }else{      file cacheDir = context.getCacheDir();      String timeStamp = String.valueOf(new Date().getTime());      file = new file(cacheDir,timeStamp+".jpg");    }    return file;  }}
