我正在制作供个人使用的电视应用程序，问题是可以在android mobile上正常工作。在android电视上，即使没有通过箭头键选择搜索视图，也不会选择gridview频道，无论鼠标如何工作。所以，请告诉我在电视上工作需要哪些额外的代码/修改。
下面我要提供代码：
public class smarttv extends AppCompatActivity {
/*

*/
public class Spacecraft {
/*

*/
private int id;
private String name;
private String mobileurl;
private String imageURL;

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getmobileurl() {
return mobileurl;
}
public void setmobileurl(String mobileurl) {
this.mobileurl = mobileurl;
}
public String gethdurl() {
return hdurl;
}
public void sethdurl(String hdurl) { this.hdurl = hdurl; }
public String getsmarttv() {
return smarttv;
}
public void setsmarttv(String smarttv) { this.smarttv = smarttv; }
public String getImageURL() {

this.imageURL = imageURL;
}
/*
