我尝试解决这个问题，但我找不到任何解决方案，所以请帮我解决。 1）我的Package.java文件：
b_indian=(Button)findViewById(R.id.b_indian);
b_classic=(Button)findViewById(R.id.b_classic);
b_royal=(Button)findViewById(R.id.b_royal);
t_pkg=(TextView)findViewById(R.id.t_pkg);
t_indian=(TextView)findViewById(R.id.t_indian);
t_classic=(TextView)findViewById(R.id.t_classic);
t_royal=(TextView)findViewById(R.id.t_royal);
b_indian.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i=new Intent(Package.this,Indianpkg.class);
startActivity(i);
}
});
b_classic.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i=new Intent(Package.this,Classicpkg.class);
startActivity(i);
}
});
b_royal.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i=new Intent(Package.this,Royalpkg.class);
startActivity(i);
}
});
}
}

答案 0 :(得分：0)
您的经典视图中的ID是错误的，更改... 我 ... for .... c ...在您的经典活动中，就像这样：
b_c_venue=(Button)findViewById(R.id.b_c_venue);
答案 1 :(得分：0)
可能是你没有在AndroidMaifest.xml中添加活动类
如果你不这样做！
将活动添加到AndroidMaifest.xml
像这样 <activity
android:name=".Classic"
android:label="your_activity_label">
</activity>
然后在Classic.java中编辑代码
b_c_venue=(Button)findViewById(R.id.b_c_venue);
b_c_decor=(Button)findViewById(R.id.b_c_decor);
b_c_caterer=(Button)findViewById(R.id.b_c_caterer);
b_c_photo=(Button)findViewById(R.id.b_c_photo);
b_c_mehandi=(Button)findViewById(R.id.b_c_mehandi);
b_c_dj=(Button)findViewById(R.id.b_c_dj);
t2=(TextView)findViewById(R.id.t2);
