在编写一个不同的类并将其设置为列表视图时，我尝试运行它，但它最终崩溃了，这有点令人失望。想知道我是否可以得到一些帮助！
这是 MainActivity 代码：
public class MainActivity extends Activity
{
private ListView list;
private ArrayAdapter<String> adapter;
private RibbonMenuView rbmView;
private Button test;
private ListView rbmListView, rbmListView2;
private ArrayAdapter<String> adapt, adapter2;
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/** Init our views **/
rbmView = (RibbonMenuView) findViewById(R.id.ribbonMenuView1);
list = (ListView) findViewById(R.id.listView1);
/** Calls "hideMenu()" after each click similiar to the Facebook or Google+ application **/
test = (Button) findViewById(R.id.button);
test.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
// shows how to hide the menu
if (rbmView != null)
{
rbmView.hideMenu();
}
}
});
/** This is the most important ListView, updating the main list in the Activity **/
final String[] items_list = { "Shop1", "Shop2", "Shop3" };
adapt = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items_list);
rbmListView = (ListView) findViewById(R.id.rbm_listview);
if (rbmListView != null)
{
rbmListView.setOnItemClickListener(new OnItemClickListener()
{
/*
* (non-Javadoc)
* @see android.widget.AdapterView.OnItemClickListener#onItemClick(android.widget.AdapterView, android.view.View, int, long)
*/
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
switch (position)
{
case 0:
String[] items = { "Location", "Contact", "Appointment" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items);
break;
case 1:
String[] items1 = { "Location", "Contact", "Appointment" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items1);
break;
case 2:
String[] items2 = { "Location", "Contact", "Appointment" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items2);
break;
/*case 3:
String[] items3 = { "Test1", "Test2", "Test3", "Test4" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items3);
break;*/
default:
String[] itemsd = { "A", "B", "C", "D" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, itemsd);
break;
}
// always update these
if (list != null)
{
list.setAdapter(adapter);
}
if (rbmView != null)
{
rbmView.hideMenu();
}
}
});
rbmListView.setAdapter(adapt);
}
/** This is the second ListView on the menu **/
final String[] items_list2 = { "About", "Deals", "Contact Developer", };
adapter2 = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items_list2);
rbmListView2 = (ListView) findViewById(R.id.rbm_listview2);
if (rbmListView2 != null)
{
rbmListView2.setOnItemClickListener(new OnItemClickListener()
{
/*
* (non-Javadoc)
* @see android.widget.AdapterView.OnItemClickListener#onItemClick(android.widget.AdapterView, android.view.View, int, long)
*/
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
switch (position)
{
case 0:
String[] items = { "About Goes Here" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items);
break;
case 1:
String[] items1 = { "Deals Goes Here" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items1);
break;
case 2:
startActivity(new Intent(MainActivity.this, ContactDev.class));
break;
}
Toast.makeText(MainActivity.this, items_list2[position], Toast.LENGTH_SHORT).show();
if (rbmView != null)
{
rbmView.hideMenu();
}
}
});
rbmListView2.setAdapter(adapter2);
}
}
/** Allows users, even API < 5, to use the back button **/
/*
* (non-Javadoc)
* @see android.app.Activity#onKeyDown(int, android.view.KeyEvent)
*/
public boolean onKeyDown(int keyCode, KeyEvent event)
{
switch (keyCode)
{
case KeyEvent.KEYCODE_BACK:
// if view is showing, close it
// all other back button clicks are handled by the phone
if (rbmView != null)
{
if (rbmView.isMenuShowing())
{
new Handler().postDelayed(new Runnable()
{
public void run()
{
rbmView.hideMenu();
}
}, 50);
}
else
{
return super.onKeyDown(keyCode, event);
}
}
break;
default:
return super.onKeyDown(keyCode, event);
}
return true;
}
/*
* (non-Javadoc)
* @see android.app.Activity#onCreateOptionsMenu(android.view.Menu)
*/
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
/*
* (non-Javadoc)
* @see android.app.Activity#onOptionsItemSelected(android.view.MenuItem)
*/
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.test:
// toggle our menu
if (rbmView != null)
{
rbmView.toggleMenu();
}
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
}
这是 ContactDev 代码：
public class ContactDev extends Activity {
Button sendEmail;
EditText msg;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contact_dev);
sendEmail = (Button) findViewById(R.id.sndBtn);
sendEmail.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
msg = (EditText) findViewById(R.id.msgTxt);
String message = msg.getText().toString();
sendEmail(message);
}
});
}
protected void sendEmail(String message) {
String[] to=new String[]{"Test@email.com"};
String subject=("Appointment");
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.putExtra(Intent.EXTRA_EMAIL, to);
emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(Intent.EXTRA_TEXT, message);
emailIntent.setType("message/rfc822");
startActivity(Intent.createChooser(emailIntent, "Gmail"));
}
}
任何帮助都会很好，或者只是在正确方向上的指导也有效！:)
