Waiting Dialog UI 및 활용

Activity 이동 시, 로딩바를 띄워야 한다.

그러면, 로딩 중이라는 것을 인지하면 기다린다.

로딩바를 중앙에 띄워야 하겠지.

1)소스

mProgressDialog = new Dialog(mPreviewBaseActivity);
mProgressDialog.setContentView(R.layout.dialog_progressbar_center);
mProgressDialog.setCancelable(false);
//mProgressDialog.setProgressStyle(android.R.style.Widget_ProgressBar_Small);
mProgressDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
mProgressDialog.show();

2)Layout XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/transparent" >

    <!-- style="@android:style/Widget.ProgressBar.Small" -->
    <ProgressBar
        android:id="@+id/progressBar1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:background="@android:color/transparent"
        android:visibility="gone"
        android:indeterminate="true"
        android:indeterminateTintMode="src_atop"
        android:indeterminateTint="@color/storecamera_yellow"/>

    />
</RelativeLayout>

3)활용

private void goActivity(){
mProgressDialog.show();
goMoveActivity();
}

private void goMoveActivity(){
   GomsLog.d(TAG, "goMoveActivity()");

   final Intent intent = new Intent(mPreviewBaseActivity, GPUImageZoomCalibrationActivity.class);
   intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_CLEAR_TOP);

   final Pair<View, String> pair1 = Pair.create(findViewById(R.id.gpuimage), "tnGPUImage");
   final Pair<View, String> pair2 = Pair.create(findViewById(R.id.tv_preview_top_title), "tnTitle");

   runOnUiThread(new Runnable() {
      @Override
      public void run() {
         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(mPreviewBaseActivity, pair1, pair2);
            ActivityCompat.startActivityForResult(mPreviewBaseActivity, intent, AppConstant.ACTIVITY_REQUEST_CODE, options.toBundle());
            CommonUtil.goSleep(2000);
            mProgressDialog.dismiss();
         } else {
            startActivityForResult(intent, AppConstant.ACTIVITY_REQUEST_CODE);
            CommonUtil.goSleep(2000);
            mProgressDialog.dismiss();
         }
      }
   });
}

ContextView를 사용한 Custom Dialog이며, 화면 전환 시, 알아서 띄워주면 된다.

오늘도 좋은 코딩 되세요 ^^
