我有一个来自exoguru的示例应用程序,其中包含cardview,每张卡片都包含一个图像和相应的文本。现在如何在点击该特定卡片时在另一个活动中显示该图像和文本?
以下是屏幕截图
这是ViewHolder,其中包含cardview的onclick
class ViewHolder extends RecyclerView.ViewHolder{
public ImageView imgThumbnail;
public TextView tvNature;
public TextView tvDesNature;
public ViewHolder(View itemView) {
super(itemView);
imgThumbnail = (ImageView)itemView.findViewById(R.id.img_thumbnail);
tvNature = (TextView)itemView.findViewById(R.id.tv_nature);
tvDesNature = (TextView)itemView.findViewById(R.id.tv_des_nature);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
v.getContext().startActivity(new Intent(v.getContext(),FullInfo.class));
}
});
}
}
这是应显示图像和文本的活动布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context="exoguru.lists.com.naturepics.FullInfo"
style="@style/Base.TextAppearance.AppCompat.Headline">
<ImageView
android:id="@+id/iv_card"
android:layout_width="match_parent"
android:layout_height="140dp" />
<TextView
android:id="@+id/tv_card_title"
android:layout_below="@+id/iv_card"
android:text="@string/hello_world" android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textSize="@dimen/abc_text_size_headline_material" />
<TextView
android:id="@+id/tv_card"
android:layout_below="@+id/tv_card_title"
android:text="@string/hello_world" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
这些是来自cardview的项目
imgThumbnail = (ImageView)itemView.findViewById(R.id.img_thumbnail); //The image
tvNature = (TextView)itemView.findViewById(R.id.tv_nature); //The Title
tvDesNature = (TextView)itemView.findViewById(R.id.tv_des_nature); //The Text
答案 0 :(得分:0)
你应该在意图上传递图像url / id / ..
Intent intent = new Intent(getBaseContext(), SignoutActivity.class);
intent.putExtra("imageinfo", imageUrl);
startActivity(intent)
目的地活动
Bundle bundle = getIntent().getExtras();
String url = bundle.getString(“imageinfo”);
