在每个卡片视图中,我有一个imageView,你可以在这段代码中看到
在第一张卡片视图中,我有图像<ImageView android:src="@drawable/new_product_icon"
我有图片<ImageView android:src="@drawable/new_order"
问题是两张卡片视图显示相同的图像,正如您所看到的,我正在使用两个不同的图像 ,那会是什么问题?
以下是我的java代码,但我认为它没有任何问题:
public class MainScreen extends AppCompatActivity {
CardView register;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
register = (CardView)findViewById(R.id.card_view);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
register.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN){
int color = getResources().getColor(R.color.cardview_shadow_start_color);
register.setBackgroundColor(color);
}
if(event.getAction() == MotionEvent.ACTION_UP){
int color = getResources().getColor(R.color.cardview_light_background);
register.setBackgroundColor(color);
}
return false;
}
});
}
public void start(View v){
Intent intent = new Intent(this,xyz.class);
startActivity(intent);
}
以及它在设备上的外观:
