화면 해상도, DPI 등 한번에 확인하기.

package com.parkhaas.screeninfo;

import android.app.Activity;

import android.os.Bundle;

import android.util.DisplayMetrics;

import android.widget.TextView;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.act_main);

TextView tv = (TextView) findViewById(R.id.main_textview);

StringBuffer sb = new StringBuffer();

DisplayMetrics dm = new DisplayMetrics();

getWindowManager().getDefaultDisplay().getMetrics(dm);

sb.append("density : ");

sb.append(dm.density);

sb.append("\n");

sb.append("densityDPI : ");

sb.append(dm.densityDpi);

sb.append("\n");

sb.append("widthPixels : ");

sb.append(dm.widthPixels);

sb.append("\n");

sb.append("heightPixels : ");

sb.append(dm.heightPixels);

sb.append("\n");

tv.setText(sb.toString());

}

}

화면 Density, DPI, 가로해상도, 세로 해상도  확인용.
