앱 시작 액티비티 변경

매니패스트 파일에

<intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

요 구문이 들어가있는 액티비티가 앱의 시작 액티비티가 된다.

저 4줄을 원하는 액티비티 내부로 이동시키면 시작 액티비티가 변경 된다.

안드로이드 환경에서

Select 문 호출시

cursor = db.rawQuery(

"SELECT contents, imagepath FROM diary WHERE month = " + month

+ " And year = " + year + " And day = " + day, null);

안드로이드 BItmap ImageView Drawable

Bitmap to ImageView

imageView.setImageBitmap(bitmap)

Resource to ImageView

imgView.setBackgroundResource(R.drawable.img1);

카메라 인텐트로 띄운후 해당 이미지 ImageView에 띄우기

1. 카메라 인텐트 띄우기

Intent intent = new Intent();
intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 1);

2. 갤러리 인텐트 띄우기

Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, 2);

인텐트 후 Image 불러오기

	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data)
	{
		if (resultCode == RESULT_OK)
		{
			if (requestCode == 1) // 1 은 위에서 startActivityForResult(intent, 1);
			{
				ImageView imageView1 = (ImageView)findViewById(R.id.imageView1);
				Bitmap bm = (Bitmap) data.getExtras().get("data");
				imageView1.setImageBitmap(bm);
			}
		}

파일 이름 일괄 변경 DarkNamer

파일명 일괄변경.exe

안드로이드에 많은 파일을 사용할시 이름 관리하기 귀찮을때 유용합니다.

package com.example.jsyproject;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationManager;

public class MyLocation {

	static Criteria criteria;

	public static double[] getMyLocation(Context context) {

		double[] result = null;

		if (criteria == null) {

			criteria = new Criteria();

			criteria.setAccuracy(Criteria.ACCURACY_COARSE); // 정확도

			criteria.setAltitudeRequired(false); // 고도

			criteria.setBearingRequired(false); // ..

			criteria.setSpeedRequired(false); // 속도

		}

		LocationManager locationManager;

		locationManager = (LocationManager) context
				.getSystemService(Context.LOCATION_SERVICE);

		// true=현재 이용가능한 공급자 제한

		String provider = locationManager.getBestProvider(criteria, true);// "gps";

		if (provider == null)
