拥有_id,hName,lName,detail,images
存储在资产中的图像
db(SQLite
)
列表布局没有图像工作正常,但图像布局显示名称不是图像(logcat没有错误)
希望将CursorAdpater
绑定到“ImageView”
public void bindView(View view, Context context, Cursor cursor) {
TextView hName = view.findViewById(R.id.hName);
hName.setText(cursor.getString(cursor.getColumnIndex("hName")));
TextView lName = view.findViewById(R.id.lName);
lName.setText(cursor.getString(cursor.getColumnIndex("lName")));
ImageView image = view.findViewById(R.id.image);
InputStream is = null;
try {
is = context.getAssets().open("birds/" + cursor.getColumnIndex("images"));
} catch (IOException e) {
e.printStackTrace();
}
Bitmap bitmap = BitmapFactory.decodeStream(is);
image.setImageBitmap(bitmap);
}
XML文件:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/image"
android:scaleType="fitCenter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:padding="24dp"
/>
<TextView
android:id="@+id/hName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="@+id/image"
android:layout_marginLeft="21dp"
android:layout_marginStart="10dp"
android:layout_toEndOf="@+id/image"
android:layout_toRightOf="@+id/image"
android:text="Name"
android:textSize="20sp"
android:textStyle="bold" />
<TextView
android:id="@+id/lName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/image"
android:layout_alignLeft="@+id/hName"
android:layout_alignStart="@+id/hName"
android:textSize="16sp"
android:text="About" />
答案 0 :(得分:0)
检查数据库中使用的图像extension
然后尝试这个
try {
is = context.getAssets().open("birds/" + cursor.getColumnIndex("images"));
Drawable d = Drawable.createFromStream(is, null);
image.setImageDrawable(d);
} catch (IOException e) {
e.printStackTrace();
}
