我一直在网上搜索几个小时，但无济于事。
我一直在开发一款应用程序，根据屏幕分辨率切换到不同的布局，但每当我尝试启动新的Activity时，应用程序崩溃......
这是我的MainActivity，从中调用新类：
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;
}
}
}
这是AndroidManifest
<?xml version="1.0" encoding="utf-8"?>
