リストビューがあり、そのリストビューでアイテムがクリックされた場合、それぞれのデータを選択して表示する必要があります.データを文字列として渡す方法とそのデータを取得する方法は? 私にとっては、名前引数を渡しました。名前を比較し、データを取得して表示する必要があります。
FirstActivity.javaで文字列を渡す方法は?
public class SouthIndianvegrecipes1 extends Activity {

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ArrayList<Recipedetails> image_details = GetSearchResults();
final ListView lv1 = (ListView) findViewById(R.id.listV_main);
lv1.setAdapter(new ItemListBaseAdapter(this, image_details));
lv1.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
Object o = lv1.getItemAtPosition(position);
Recipedetails obj_itemDetails = (Recipedetails)o;
Toast.makeText(SouthIndianvegrecipes1.this, "You have chosen : " + " " + obj_itemDetails.getName(), Toast.LENGTH_LONG).show();
Intent newActivity = new Intent(SouthIndianvegrecipes1.this,
SouthIndianvegmanualrecipes.class );
newActivity.putExtra("name", obj_itemDetails.getName());
startActivity(newActivity);
}
});

ここで、文字列機能を配置または保存して、レイアウトに従って名前、画像、材料、メソッドを配置する必要があります。 if 関数の後に、間違ったコード、layout.xml を配置します。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<ImageView
android:id="@+id/photo"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_gravity="top"
android:padding="20dp"
android:scaleType="center"
></ImageView>
<TextView android:id="@+id/name"
android:textSize="14sp"
android:textStyle="bold"
android:textColor="#32cd32"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/photo"/>
<TextView
android:text="Ingredients:"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="left" />
<TextView android:id="@+id/itemIngredients"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center" />
<TextView
android:text="Method:"

<TextView android:id="@+id/methods"

android:layout_height="wrap_content"
android:scaleType="center" />
</LinearLayout>
文字列を渡す方法と、それを比較してフェッチして表示する方法は? または、その方法をいくつかリンクできますか？
私のコードが比較していて、なぜデータが表示されないのか、デフォルトのレイアウトのみを表示しています
