私は何時間もオンラインで検索してきましたが、役に立ちませんでした。
画面の解像度に応じて異なるレイアウトに切り替えるアプリに取り組んでいますが、新しいアクティビティを開始しようとすると、アプリがクラッシュします...
これは、新しいクラスが呼び出される私の MainActivity です。
package com.example.mywallpapers;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Point;
import android.os.Build;
import android.os.Bundle;
import android.view.Display;
import android.view.WindowManager;
import android.widget.Toast;
public class MainActivity extends Activity {
@SuppressWarnings("deprecation")
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
int width = 0;
Point size = new Point();
WindowManager w = getWindowManager();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
w.getDefaultDisplay().getSize(size);
width = size.x;
} else {
Display d = w.getDefaultDisplay();
width = d.getWidth();
}
switch (width) {
case 480:
Toast.makeText(getApplicationContext(),
"Your screen width is " + width,
Toast.LENGTH_SHORT).show();
startActivity(new Intent(MainActivity.this,
FourEightyEightHundred.class));
break;
case 720:
Toast.makeText(getApplicationContext(),
"Your screen width is " + width,
Toast.LENGTH_SHORT).show();
break;
}
}
}
これは AndroidManifest です
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
