簡單的 Android 拍照并顯示以及獲取路徑后上傳

Activity 中的代碼，我只貼出重要的事件部分代碼

public void doPhoto(View view){destoryBimap();String state = Environment.getExternalStorageState();if (state.equals(Environment.MEDIA_MOUNTED)) {Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");startActivityForResult(intent, 1);} else {Toast.makeText(MainActivity.this, "沒有SD卡", Toast.LENGTH_LONG).show();}}@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data){Uri uri = data.getData();if (uri != null) {this.photo = BitmapFactory.decodeFile(uri.getPath());}if (this.photo == null) {Bundle bundle = data.getExtras();if (bundle != null) {this.photo = (Bitmap) bundle.get("data");} else {Toast.makeText(MainActivity.this, "拍照失敗", Toast.LENGTH_LONG).show();return;}}FileOutputStream fileOutputStream = null;try {// 獲取 SD 卡根目錄String saveDir = Environment.getExternalStorageDirectory() + "/meitian_photos";// 新建目錄File dir = new File(saveDir);if (! dir.exists()) dir.mkdir();// 生成文件名SimpleDateFormat t = new SimpleDateFormat("yyyyMMddssSSS");String filename = "MT" + (t.format(new Date())) + ".jpg";// 新建文件File file = new File(saveDir, filename);// 打開文件輸出流fileOutputStream = new FileOutputStream(file);// 生成圖片文件this.photo.compress(Bitmap.CompressFormat.JPEG, 100, fileOutputStream);// 相片的完整路徑this.picPath = file.getPath();ImageView imageView = (ImageView) findViewById(R.id.showPhoto);imageView.setImageBitmap(this.photo);} catch (Exception e) {e.printStackTrace();} finally {if (fileOutputStream != null) {try {fileOutputStream.close();} catch (Exception e) {e.printStackTrace();}}}}/*** 銷毀圖片文件*/private void destoryBimap(){if (photo != null && ! photo.isRecycled()) {photo.recycle();photo = null;}}

Layout 布局頁面

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical"><ScrollViewandroid:layout_width="fill_parent"android:layout_height="fill_parent"><LinearLayoutandroid:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical"><Buttonandroid:id="@+id/doPhoto"android:layout_width="fill_parent"android:layout_height="wrap_content"android:padding="10dp"android:layout_marginBottom="10dp"android:text="拍照"android:onClick="doPhoto"/><TextViewandroid:id="@+id/showContent"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginBottom="10dp"/><ImageViewandroid:id="@+id/showPhoto"android:layout_width="fill_parent"android:layout_height="250dp"android:scaleType="centerCrop"android:src="@drawable/add"android:layout_marginBottom="10dp"/></LinearLayout></ScrollView> </LinearLayout>
