我想在单击按钮时将图片从我的画廊添加到最喜欢的类别，并在单击按钮时从最喜欢的类别中删除。我真的不知道该怎么做。我是 android 的新手。我认为第一个当我单击按钮时，我需要获取背景图像的 ID，然后在数据库中发送图片 ID，它可以安全和延迟。我就在这条路上？当我点击她时，按钮切换。（灰色和黄色）有我的源代码 final String MY_LOG = "mylog"; 画廊画廊；图像视图图像视图；
Button sportButton;
int[] imgID = { R.drawable.sport_0, R.drawable.sport_1, R.drawable.sport_2,
R.drawable.sport_3, R.drawable.sport_4, R.drawable.sport_5,
R.drawable.sport_6, R.drawable.sport_7, R.drawable.sport_8,
R.drawable.sport_9, };
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sport);
imageView = (ImageView) findViewById(R.id.ImageSportView);
imageView.setImageResource(imgID[0]);
gallery = (Gallery) findViewById(R.id.SportGallery);
gallery.setAdapter(new AddImgAdapter(this));
gallery.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> perent, View view,
int position, long id) {
imageView.setImageResource(imgID[position]);
Log.d(MY_LOG, "img Id"+position);
}
});
}
public void onClickButton(View button) {
if (button.isSelected()) {
button.setSelected(false);
} else {
button.setSelected(true);
gallery.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> perent, View view,
int position, long id) {
Log.d(MY_LOG, "img Id"+position);
}
});
}
Log.d(MY_LOG, "on button sportClick");
}
