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 
 @Overrideprotected 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, 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),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;}}
