.... != ring ati def 寫入 private span amp

之前採用的方式（返回的照片會被壓縮，不能達到預期效果）：

Intent intent = new Intent();
Intent intent_camera = getPackageManager()
.getLaunchIntentForPackage("com.android.camera");
if (intent_camera != null) {
intent.setPackage("com.android.camera");
}
intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 100);

回調：（在返回的data中區數據，然後保存，然後再拿到路徑。這樣圖片是已經壓縮了的）

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("TAG", "requestCode" + requestCode + " ,resultCode" + resultCode
+ data);
if (requestCode == 100 && resultCode == Activity.RESULT_OK
&& null != data) {

// 照相返回界面
String sdState = Environment.getExternalStorageState();
if (!sdState.equals(Environment.MEDIA_MOUNTED)) {
Toast.makeText(getApplicationContext(), "未找到SDK",
Toast.LENGTH_LONG).show();
Log.d("TAG", "sd card unmount");
return;
}
new DateFormat();
String name = DateFormat.format("yyyyMMdd_hhmmss",
Calendar.getInstance(Locale.CHINA))
+ ".jpg";
Log.d("TAG", "name.........." + name);
Bundle bundle = data.getExtras();
// 獲取相機返回的數據，並轉換為圖片格式
Bitmap bitmap;
String filename = null;
bitmap = (Bitmap) bundle.get("data");
FileOutputStream fout = null;
// 定義文件存儲路徑
File file = new File("/sdcard/e_community/");
if (!file.exists()) {
file.mkdirs();
}
filename = file.getPath() + "/" + name;
try {
fout = new FileOutputStream(filename);
// 對圖片進行壓縮
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fout);
// FileOutputStream outputStream = new FileOutputStream(filename); // 文件輸出流
// outputStream.write(data); // 寫入sd卡中
// outputStream.close(); // 關閉輸出流
} catch (FileNotFoundException e) {
e.printStackTrace();
} finally {
try {
fout.flush();
fout.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Log.d("TAG", "相片路徑" + filename);

}

解決圖片太小的問題。就是在啟動相機的時候設置好照片保存的路徑以及名稱，這樣data中就不會返回數據而是null，這樣就能夠依據自己設置的路徑已經設置的名稱通過BitmapFactory.decodeFile(imageUrl.get(j),option);獲取到照片。

啟動代碼例如以下：

private String camera_path = Environment.getExternalStorageDirectory().toString()+"/e_community/";保存的路徑

private String camera_photo_name;//保存的名稱

Uri mOutPutFileUri;

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File path1 = new File(PhotoUtil.camera_path);
if(!path1.exists()){
path1.mkdirs();
}
camera_photo_name=System.currentTimeMillis()+".png";
File file = new File(path1,camera_photo_name);
mOutPutFileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mOutPutFileUri);

startActivityForResult(intent, 111);

回調：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("TAG", "requestCode" + requestCode + " ,resultCode" + resultCode
+ data);
if (requestCode == 111&&resultCode==Activity.RESULT_OK) {
// 照相返回界面
String filename = PhotoUtil.camera_path+ "/" + camera_photo_name;
Log.d("TAG", "相片路徑" + filename);

}

}

Intent調用系統拍照程序，返回圖片太小的問題
