对于 Android 编程类，我试图实现一个 QuickAction Activity，但我无法将它加载到我的程序中。这是我认为加载失败的代码。

setContentView(R.layout.activity_main);
//show on iBtn1
ImageButton iBtn1 = (ImageButton) this.findViewById(R.id.iBtn1);
iBtn1.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
startActivity(new Intent(getApplicationContext(),
QuickActionBar.class));
}
});
final QuickActionIcons edit = new QuickActionIcons();;
edit.setTitle("Edit");
edit.setIcon(getResources().getDrawable(R.drawable.edit));
edit.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
Toast.makeText(MainActivity.this,"Edit Contact",Toast.LENGTH_SHORT).show();
}

final QuickActionIcons call = new QuickActionIcons();;
call.setTitle("Call");
call.setIcon(getResources().getDrawable(R.drawable.call));
call.setOnClickListener(new OnClickListener()

final QuickActionIcons call3 = new QuickActionIcons();;

}
});
QuickActionBar qab = new QuickActionBar(iBtn1);
qab.addItem(edit);
qab.addItem(call);
qab.addItem(send_data);
qab.addItem(call1);
qab.addItem(call2);
qab.addItem(call3);
qab.setAnimationStyle(QuickActionBar.GROW_FROM_LEFT);
qab.show();
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
这是我的 LogCat
