007.androidUI开发进阶(基础--案例) .
1.Dialog有四种,分别是AlertDialog，ProgressDialog，DatePickerDialog，TimePickerDialog
1.1AlertDialog
public class MainActivity extends Activity {
private View view;
private TextView tView;
private EditText eText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LayoutInflater layoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
view = layoutInflater.inflate(R.layout.cell, null);
tView = (TextView) view.findViewById(R.id.tv2);
eText = (EditText) view.findViewById(R.id.et1);
new AlertDialog.Builder(this).setTitle("友情提示").setView(view)
.setMessage("确定退出？")
.setNegativeButton("取消", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "确定",
Toast.LENGTH_SHORT).show();
}
}).setNeutralButton("中立", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "取消",
Toast.LENGTH_SHORT).show();
}
}).setPositiveButton("确定", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, eText.getText()
.toString(), Toast.LENGTH_SHORT).show();
// tView.setText(eText.getText().toString());
}
}).show();
}
}
1.2ProgressDialog
ProgressDialog pgd = new ProgressDialog(this);
pgd.setTitle("nihao");
pgd.setMessage("hehe");
//pgd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pgd.setProgress(100);
pgd.show();
1.3DatePickerDialog
DatePickerDialog datePickerDialog = new DatePickerDialog(this,new OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
}
}, myear,mmouth,mday);datePickerDialog.show();
1.4 TimePickerDialog
于1.3相同的使用方式。
2.Menu有三种：分别是：optionsMenu，SubMenu，ContextMenu
2.1.OptionsMenu
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(menu.NONE,1,menu.NONE,"菜单1");
menu.add(menu.NONE,2,menu.NONE,"菜单2");
menu.add(menu.NONE,3,menu.NONE,"菜单3");
menu.add(menu.NONE,4,menu.NONE,"菜单4");
menu.add(menu.NONE,5,menu.NONE,"菜单5");
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 1:
Toast.makeText(this,"1", Toast.LENGTH_SHORT).show();
break;
default:
Toast.makeText(this,"其他", Toast.LENGTH_SHORT).show();
break;
}
return super.onOptionsItemSelected(item);
}
2.2.SubMenu
@Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(menu.NONE,1,menu.NONE,"菜单1");
menu.add(menu.NONE,2,menu.NONE,"菜单2");
menu.add(menu.NONE,3,menu.NONE,"菜单3");
menu.add(menu.NONE,4,menu.NONE,"菜单4");
menu.add(menu.NONE,5,menu.NONE,"菜单5");
SubMenu subMenu = menu.addSubMenu(menu.NONE,6,menu.NONE,"菜单6");
subMenu.setHeaderTitle("你好");
subMenu.setIcon(R.drawable.ic_launcher);
subMenu.addSubMenu(menu.NONE,7,menu.NONE,"菜单7");
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 1:
Toast.makeText(this,"1", Toast.LENGTH_SHORT).show();
break;
default:
Toast.makeText(this,"其他", Toast.LENGTH_SHORT).show();
break;
}
return super.onOptionsItemSelected(item);
}
2.3ContextMenu
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView textView = (TextView) findViewById(R.id.tv1);
registerForContextMenu(textView);
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
menu.add(menu.NONE,1,menu.NONE,"菜单1");
menu.add(menu.NONE,2,menu.NONE,"菜单2");
menu.add(menu.NONE,3,menu.NONE,"菜单3");
menu.add(menu.NONE,4,menu.NONE,"菜单4");
menu.add(menu.NONE,5,menu.NONE,"菜单5");
super.onCreateContextMenu(menu, v, menuInfo);
}
@Override
public boolean onContextItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case 1:
Toast.makeText(this,"1",Toast.LENGTH_SHORT).show();
break;
default:
break;
}
return super.onContextItemSelected(item);
}
}
3.Notification
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
//声明Notification
Notification notification = new Notification();
//设置notification的参数
notification.icon=R.drawable.ic_launcher;
Intent intent = new Intent(this,MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0, intent,0);
notification.setLatestEventInfo(this,"haha" ,"contentText",pendingIntent);
notificationManager.notify(10,notification);
4.TabHost
TabHost tabHost = getTabHost();
LayoutInflater.from(this).inflate(R.layout.activity_main,
tabHost.getTabContentView(), true);
Intent intent = new Intent(MainActivity.this, SeocndActivity.class);
tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("搜索")
.setContent(intent));
tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("搜索")
.setContent(intent));
tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("搜索")
.setContent(R.id.l1));
