Cardview onclick无法启用波纹效果

Question

这是我到目前为止所取得的成就

图像适配器

public class ImageAdapter extends BaseAdapter {
private Context mContext;
TextView text;
ImageView imageView;

// Constructor
public ImageAdapter(Context c) {
    mContext = c;
}

public int getCount() {
    return mThumbIds.length;
}

public Object getItem(int position) {
    return null;
}

public long getItemId(int position) {
    return 0;
}

// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
    View view = View.inflate(mContext, R.layout.grid_view, null);
    RelativeLayout rl = (RelativeLayout) view.findViewById(R.id.relaGrid);

    ImageView image = (ImageView) rl.findViewById(R.id.chooseImage);
    TextView text = (TextView) rl.findViewById(R.id.chooseText);       
    image.setImageResource(mThumbIds[position]);
    text.setText(mThumbTxt[position]);
    Typeface customFont = Typeface.createFromAsset(mContext.getAssets(), "fonts/faruma.ttf");
    text.setTypeface(customFont);
    return rl;
}

// Keep all Images in array
public Integer[] mThumbIds = {
    R.drawable.ic_action_gallery, R.drawable.ic_action_gallery,
    R.drawable.ic_action_gallery, R.drawable.ic_action_gallery,
    R.drawable.ic_action_gallery, R.drawable.ic_action_gallery,
    R.drawable.ic_action_gallery, R.drawable.ic_action_gallery
};

private String[] mThumbTxt = {
    "ހެނދުނުގެ ޛިކުރު", "ހަވީރުގެ ޛިކުރު", "İbadethanddjjdjdjdjdjdj deler", "Hepsi", "Abo", 
    "Ryhan", "Haly", "Arush"
};

}

我正在尝试通过onclick监听器在cardview上产生连锁反应，从而启动另一个目的。但是启用波纹效果后，onclick事件将无法正常工作。我只看到涟漪效应而已。 Onclick侦听器不起作用。如何实现两者？请帮助

Answer 1

[首先，尝试使用XML在CardView上设置侦听器。声明一个方法，其中包含单击时应执行的操作。然后，实现它：

类似：-

android:onClick = "(method)"

如果不起作用，则在相对布局上设置onClickListener，该相对布局是CardView的子级。像：-

relativeLayout.setOnClickListener ...

这应该用Java完成。
