Android设置拍照或者上传本地图片

效果如下：

看代码：

MainActivity类中：

package com.example.ceshidemo;import java.io.ByteArrayOutputStream;

import android.widget.Toast;public class MainActivity extends Activity {private static final int PHOTO_REQUEST_CAREMA = 1;private static final int PHOTO_REQUEST_GALLERY = 2;private static final int PHOTO_REQUEST_CUT = 3;private static final String PHOTO_FILE_NAME = "temp_photo.jpg";private File tempFile;private CircleImageView headIcon;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initView();}private void initView() {headIcon = (CircleImageView) findViewById(R.id.headIcon);headIcon.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubchangeHeadIcon();}});changeTheme();File file = new File(MainActivity.this.getFilesDir(), "_head_icon.jpg");if (file.exists()) {headIcon.setImageURI(Uri.fromFile(file));}}private void changeTheme() {Calendar c = Calendar.getInstance();System.out.println(c.get(Calendar.HOUR_OF_DAY));if (c.get(Calendar.HOUR_OF_DAY) < 18 && c.get(Calendar.HOUR_OF_DAY) >= 6) {headIcon.setImageResource(R.drawable.ic_hehe);} else {headIcon.setImageResource(R.drawable.ic_launcher);}}private void changeHeadIcon() {final CharSequence[] items = { "相册", "拍照" };AlertDialog dlg = new AlertDialog.Builder(MainActivity.this).setTitle("选择图片").setItems(items, new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int item) {// 这里item是根据选择的方式，if (item == 0) {Intent intent = new Intent(Intent.ACTION_PICK);intent.setType("image/*");startActivityForResult(intent,PHOTO_REQUEST_GALLERY);} else {Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {tempFile = new File(Environment.getExternalStorageDirectory(),PHOTO_FILE_NAME);Uri uri = Uri.fromFile(tempFile);intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);startActivityForResult(intent,PHOTO_REQUEST_CAREMA);} else {Toast.makeText(MainActivity.this, "未找到存储卡，无法存储照片！",Toast.LENGTH_SHORT).show();}}}}).create();dlg.show();}@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);if (requestCode == PHOTO_REQUEST_GALLERY) {if (data != null) {Uri uri = data.getData();Log.e("图片路径？？", data.getData() + "");crop(uri);}} else if (requestCode == PHOTO_REQUEST_CAREMA) {if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {crop(Uri.fromFile(tempFile));} else {Toast.makeText(MainActivity.this, "未找到存储卡，无法存储照片！",Toast.LENGTH_SHORT).show();}} else if (requestCode == PHOTO_REQUEST_CUT) {if (data != null) {final Bitmap bitmap = data.getParcelableExtra("data");headIcon.setImageBitmap(bitmap);// 保存图片到internal storageFileOutputStream outputStream;try {ByteArrayOutputStream out = new ByteArrayOutputStream();bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);out.flush();// out.close();// final byte[] buffer = out.toByteArray();// outputStream.write(buffer);outputStream = MainActivity.this.openFileOutput("_head_icon.jpg",Context.MODE_PRIVATE);out.writeTo(outputStream);out.close();outputStream.close();} catch (Exception e) {e.printStackTrace();}}try {if (tempFile != null && tempFile.exists())tempFile.delete();} catch (Exception e) {e.printStackTrace();}}}private void crop(Uri uri) {Intent intent = new Intent("com.android.camera.action.CROP");intent.setDataAndType(uri, "image/*");intent.putExtra("crop", "true");intent.putExtra("aspectX", 1);intent.putExtra("aspectY", 1);intent.putExtra("outputX", 250);intent.putExtra("outputY", 250);intent.putExtra("outputFormat", "JPEG");intent.putExtra("noFaceDetection", true);intent.putExtra("return-data", true);startActivityForResult(intent, PHOTO_REQUEST_CUT);}
}

在这里自定了一个圆形的View：CircleImageView

main_activity.xml文件：
