我有这个AlertDialog，并且当我选择yes选项时程序自动关闭时会出现错误。任何人也许可能是我做错了什么？这是代码和logcat。
new AlertDialog.Builder(HIITActivity.this)
.setIcon(R.drawable.ic_launcher)
.setTitle("[" + file.getName() + "]")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
if(songchooser==1)
{
path1=file.getAbsolutePath();
}
else
{
path2=file.getAbsolutePath();
}
gohome(view);
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
}).show();
}
}});
继承logcat
