Call list item intent from your application class:
Intent intent = new Intent(MyFirstAppActivity.this, LentList.class);
startActivity(intent);
Here, MyFirstAppActivity is the main class and LentList is the class where list items would show.
First, create a layout file under layout folder, such named list.xml and paste the following content:
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView android:id="@android:id/list" android:layout_width="match_parent" android:layout_height="wrap_content" />
</LinearLayout>
Now create LentIist.java class:
public class LentList extends ListActivity
private ArrayList<LentPerson> liLentPerson;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list);
this.generateLentPersons();
setListAdapter(new MyAdapter(this, android.R.layout.simple_list_item_1, liLentPerson.toArray()));
}
Function: generateLentPersons() is as following:
Function MyAdapter is as following:
Intent intent = new Intent(MyFirstAppActivity.this, LentList.class);
startActivity(intent);
Here, MyFirstAppActivity is the main class and LentList is the class where list items would show.
First, create a layout file under layout folder, such named list.xml and paste the following content:
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView android:id="@android:id/list" android:layout_width="match_parent" android:layout_height="wrap_content" />
</LinearLayout>
Now create LentIist.java class:
public class LentList extends ListActivity
private ArrayList<LentPerson> liLentPerson;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list);
this.generateLentPersons();
setListAdapter(new MyAdapter(this, android.R.layout.simple_list_item_1, liLentPerson.toArray()));
}
Function: generateLentPersons() is as following:
private ArrayList<Person> getPersons() { ArrayList<Person> liPerson = new ArrayList<Person>(); person = new Person(1, "Pritom Kumar", "Software Engineer", "KU"); return liPerson; }
private class MyAdapter extends ArrayAdapter<Object> { public MyAdapter(Context context, int resource, Object[] persons) { super(context, resource, persons); } public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); View row = inflater.inflate(R.layout.list_each, parent, false); LentPerson p = (Person) getItem(position); TextView textView1 = (TextView) row.findViewById(R.id.textView1); TextView textView2 = (TextView) row.findViewById(R.id.textView2); TextView textView3 = (TextView) row.findViewById(R.id.textView3); textView1.setText(p.getName()); /* Pritom Kumar */ textView2.setText(p.getDesignation()); /* Software Engineer */ textView3.setText(p.getUniversity()); /* KU */ /* Bind event on row click */ row.setOnClickListener(new OnItemClickListener(p)); return row; } }
Layout file list_each.xml as following:
<?xml version="1.0" encoding="UTF-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tableLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Medium Text" android:textAppearance="?android:attr/textAppearanceMedium" /> <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Small Text" android:textAppearance="?android:attr/textAppearanceSmall" /> <TextView android:id="@+id/textView3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Small Text" android:textAppearance="?android:attr/textAppearanceSmall" /> </TableLayout>
private class OnItemClickListener implements OnClickListener{ private LentPerson p; public OnItemClickListener(LentPerson p) { this.p = p; } public void onClick(View arg0) { Toast.makeText(LentList.this, p.getName(), Toast.LENGTH_SHORT).show(); Intent intent = new Intent(LentList.this, PersonDetails.class); intent.putExtra("personId", p.getId()); intent.putExtra("txtName", p.getName()); intent.putExtra("txtBorrower", p.getborrower()); intent.putExtra("txtCategory", p.getCategory()); startActivity(intent); } }
Java class PersonDetails is as following:
package com.pkm.andrd; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class PersonDetails extends Activity { private TextView textView2; private TextView textView4; private TextView textView6; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.persondetails); textView2 = (TextView) findViewById(R.id.textView2); textView4 = (TextView) findViewById(R.id.textView4); textView6 = (TextView) findViewById(R.id.textView6); textView2.setText(getIntent().getExtras().getString("txtName")); textView4.setText(getIntent().getExtras().getString("txtBorrower")); textView6.setText(getIntent().getExtras().getString("txtCategory")); } }Layout R.layout.persondetails is as following:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/textView7" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/s2610132158" android:textAppearance="?android:attr/textAppearanceLarge" /> <TableRow android:id="@+id/tableRow1" android:layout_width="match_parent" android:layout_height="wrap_content" > <LinearLayout android:id="@+id/linearLayout1" android:layout_width="wrap_content" android:layout_height="wrap_content" > <TextView android:id="@+id/textView1" android:layout_width="90dp" android:layout_height="wrap_content" android:text="@string/Name" android:textAppearance="?android:attr/textAppearanceMedium" /> </LinearLayout> <TextView android:id="@+id/textView2" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Medium Text" android:textAppearance="?android:attr/textAppearanceMedium" /> </TableRow> <LinearLayout android:id="@+id/linearLayout2" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <TextView android:id="@+id/textView3" android:layout_width="90dp" android:layout_height="wrap_content" android:text="@string/borrower" android:textAppearance="?android:attr/textAppearanceMedium" /> <TextView android:id="@+id/textView4" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Medium Text" android:textAppearance="?android:attr/textAppearanceMedium" /> </LinearLayout> <LinearLayout android:id="@+id/linearLayout3" android:layout_width="match_parent" android:layout_height="wrap_content" > <TextView android:id="@+id/textView5" android:layout_width="90dp" android:layout_height="wrap_content" android:text="@string/category" android:textAppearance="?android:attr/textAppearanceMedium" /> <TextView android:id="@+id/textView6" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Medium Text" android:textAppearance="?android:attr/textAppearanceMedium" /> </LinearLayout> </LinearLayout>
Make sure you have the following entry in your manifest file under application tag:
<activity android:name=".LentList" />
<activity android:name=".PersonDetails" />
