android 更换皮肤项目

android换肤项目是本人学习android不到一个月做的第一个项目，所以有很多可以优化的地方，仅给大家提供一个参考。

});

}

}

上面这个是主activity 采用dialog imagebutton 相结合

上面这个是保存选中的主题

下面这个是随机换肤

package wang.sc;

import java.util.Random;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.app.AlertDialog.Builder;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.LinearLayout;
import android.widget.ProgressBar;
import android.widget.Toast;

public class jindu extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);

requestWindowFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.jindu);
setProgressBarVisibility(true);
ProgressBar pb = (ProgressBar) findViewById(R.id.pb);
setProgress(pb.getProgress()*100);
setSecondaryProgress(pb.getSecondaryProgress()*100);
try{
Thread.sleep(3000);
}
catch(Exception e){
e.printStackTrace();
}
finally
{

}
Random r = new Random();
int s = Math.abs(r.nextInt())%5;
String[]a ={"qingchun","huanghun","weilan","jiqing","lvyi"};
if((a[s].equals(a[0]))){
Toast.makeText(jindu.this, "尽情的在青春飞扬世界里畅游吧",Toast.LENGTH_SHORT).show();
Intent intent = new Intent();
intent.setClass(jindu.this,Qingchun.class);
jindu.this.startActivity(intent);
finish();
}
if((a[s].equals(a[1]))){
Toast.makeText(jindu.this, "尽情的在黄昏静谧世界里畅游吧",Toast.LENGTH_SHORT).show();
Intent intent = new Intent();
intent.setClass(jindu.this,Huanghun.class);
jindu.this.startActivity(intent);
finish();
}
if((a[s].equals(a[2]))){
Toast.makeText(jindu.this, "尽情的在深度蔚蓝世界里畅游吧",Toast.LENGTH_SHORT).show();
Intent intent = new Intent();
intent.setClass(jindu.this,weilan.class);
jindu.this.startActivity(intent);
finish();
}
if((a[s].equals(a[3]))){
Toast.makeText(jindu.this, "尽情的在激情四射世界里畅游吧",Toast.LENGTH_SHORT).show();
Intent intent = new Intent();
intent.setClass(jindu.this,jiqing.class);
jindu.this.startActivity(intent);
finish();
}
if((a[s].equals(a[4]))){
Toast.makeText(jindu.this, "尽情的在绿意盎然世界里畅游吧",Toast.LENGTH_SHORT).show();
Intent intent = new Intent();
intent.setClass(jindu.this,lvyi.class);
jindu.this.startActivity(intent);
finish();
}

}
}

下面是sharedpreference

package wang.sc;

import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;

public class SharedPref {

public void setpreference(Activity act, int id, int id2) {
SharedPreferences sp = act.getSharedPreferences("zhuti",
Activity.MODE_PRIVATE);
sp.edit().putInt("dr", id).putInt("st", id2).commit();
}
public int getpreferencedr(Activity act)
{
SharedPreferences sp =
act.getSharedPreferences("zhuti",Context.MODE_WORLD_READABLE);
int dra = sp.getInt("dr", R.drawable.xiangji);
return dra;
}
public int getpreferencest(Activity act)
{
SharedPreferences sp =
act.getSharedPreferences("zhuti",Context.MODE_WORLD_READABLE);
int dra = sp.getInt("st",R.style.qingchun);
return dra;
}

}

配置文件相对简单在此不在赘述。作者— 河北北方学院 —醉雨蝶
