</TableLayout>

2.Toast.makeText(MainActivity.this,”ANY_STRING_IS_OK”,Toast.LENGTH_SHORT).show();

3.TextView

android:drawableBottom

android:drawableLeft

android:drawableRight

android:drawableTop         //Make picture around text

android:singleLine             //When beyond one line,……

android:autoLink                //none,web,email,phone,map,all

4.EditText login = (EditText)findViewById(R.id.login);

   String loginText = login.getText().toString();

5.Click Button

Button button1 = (Button)findViewById(R.id.button1);

   button1.setOnClickListener(new OnClickListener(){

   @override

public void onClick(View v){

EditText nicknameET = (EditText)findViewById(R.id.nickname);  //get name

String nickname = nicknameET.getText().toString();      //get input name

EditText pwdET = (EditText)findViewById(R.id.pwd);           //get pass part

String pwd = pwdET.getText().toString();                              //get input pass

Log.i(“My name is” + nickname);

}

});

6.Click RadioGroup(Single-choice)

@.xml

<RadioGroup

android:id=”@id/radioGroup1”

android:orientation=“horizontal”

android:layout_width=“wrap_content”

android:layout_heigth=“wrap_content”

<RadioButton

android:id=”@id/radio1”

android:orientation=“horizontal”

android:layout_width=“wrap_content”

android:layout_heigth=“wrap_content”/>

   </RadioGroup>

@.java

RadioGroup sex = (RadioGroup)findViewById(R.id.radioGroup1);

sex.setOnCheckedChangeListener(new OnCheckedChangeListener(){

@override

public void onCheckedChanged(RadioGroup group,int checkedId){

RadioButton r = (RadioButton)findViewById(checkedId);

r.getText();

}

});

//for(int i = 0;i<sex.getChidCount();i++){

// RadioButton r = (RadioButton)sex.getChildAt(i);

// if(r.isChecked()){r.getText();break;}}}});

7.Multiselect(CheckBox)

final CheckBox like1 = (CheckBox)findViewById(R.id.like1);

like1.setOnCheckedChangeListener(new OnCheckedChangeListener(){

@override

public void onCheckedChanged(CompoundButton buttonView,boolean isChecked){

if(like1.isChecked()){like1.getText();}

}});

8.ImageView

android:adjustViewBounds              //Keep size rate

9.Spinner

<Spinner

android:prompt=“@string/info”                          //tip

android:entries=“@array/ctype”

android:layout_height=“wrap_content”

android:layout_height=“wrap_content”>

</Spinner>

@res\values

<?xml version=“1.0” encoding=“utf-8”?>

<resources>

<string-array name =“ctype”>

</resource>

@.java

Spinner spinner = (Spinner)findViewById(R.id.spinner1);

spinner.getSelectedItem();

spinner.setOnItemSelectedListener(new onItemSelectedListener(){

@override

public void onItemSelected(AdapterView<?> parent,View arg1,int pos,long id){

String result = parent.getItemAtPosition(pos).toString();

Log.i(“Spinner”,result);

}

@override

public void onNothingSelected(AdapterView<?> arg0){}

}

});

10.Adapter

When you create an Adapter,you can use the resource files of array or create in java files.

1>ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(

this,R.array.ctype,android.R.layout.simple_dropdown_item_1line);

//Create an Adapter

String[] ctype = new String[]{“123”,”234”,”345”};

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,ctype);

2>adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

3>spinner.setAdapter(adapter);

11.ListView

@.xml

simple_list_item1                  //Every list is text

simple_list_item2                  //TextSize bigger

simple_list_item_checked           //checked for each list 

simple_list_item_multiple_choice   //multiple_choice for each list

simple_list_item_simple_choice     //simple_choice for each list

android:divider                    //You can use color or Drawable

android:dividerHeight      

android:entries

android:footerDivedersEnable       //true(need use addFooterView()) or false

android:headerDivedersEnable       //true(need use addHeaderView()) or false

@.java(method)

final ListView listView = (ListView)findViewById(R.id.listView1);

listView.addHeaderView(line());    //set heaer_view

ArraryAdapter<CharSequence> adapter = ArraryAdapter.createFromResource(

this,R.array.ctype,android.R.layout.simple_list_item_checked);         

listView.setAdapter(adapter);

listView.addFooterView(line());

listView.setOnItemClickListener(new OnItemClickListener(){

@override

public void onItemClick(AdapterView<?> parent,View arg1,int pos,long id){

String result = parent.getItemAtPosition(pos).toString();

Toast.makeText(MainActivity.this,result,Toast.LENGTH_SHORT).show();

}

});

@.java(extend)

public class MainActivity extends ListActivity{

@override

public void onCreate(Bundle savedInstanceState){

super.onCreate(savedInstanceState);

/////////////////////////

String[] ctype = new String[]{"123","234","345"};

ArraryAdapter<String> adapter = new ArraryAdapter<String>(this,

android.R.layout.simple_list_item_single_choice,ctype);

setListAdapter(adapter);

}

}

@override

protected void onListItemClick(ListView l,View v,int p){

super.onListItemClick(l,v,position,id);

String result = l.getItemAtPosition(position).toString();

Toast.makeText(MainActivity.this,result,Toast.LENGTH_SHORT).show();

}

}

12.Time

@.xml

<DatePicker

android:layout_width = “wrap_content”

android:layout_height = “wrap_content”/>

<TimePicker

android:layout_width = “wrap_content”

android:layout_height = “wrap_content”/>

@.java

DatePicker datepicker  = (DatePicker)findViewById(R.id.datePicker1);

TimePicker timepicker  = (TimePicker)findViewById(R.id.timePicker1);

time picker.setIs24HourView(true);

Calendar calendar = Calendar.getInstance();

year = calendar.get(Calendar.YEAR);

month = calendar.get(Calendar.MONTH);

day = calendar.get(Calendar.DAY_OF_MONTH);

hour = calendar.get(Calendar.HOUR_OF_DAY);

minute = calendar.get(Calendar.DAY_OF_MINUTE);

datePicker,init(year,month,day,new OnDateChangedListener(){

@override

public void onDateChanged(DatePicker arg0,int year,int month,int day){

MainActivity.this.year = year;

MainActivity.this.month = month;

MainActivity.this.day = day;

show(year,month,day,hour,minute);

}

});

timePicker.setOnTimeChangedListener(new OnTimeChangedListener(){

@override

public void onTimeChangedListener(TimePicker view,int hourOfDay,int minute){

MainActivity.this.hour = hourOfDay;

MainActivity.this.minute = minute;

show(year,month,day,hourOfDay,minute);

}

});

private void show(int year,int month,int day,int hour,int minute){

String str = year+"-"+(month+1)+"-"+day+"-"+hour+":"+minute;

Toast.makeText(this,str,Toast.LENGTH_SHORT).show();

}

13.Chronometer

@.xml

<chronometer

android:text = "Chronometer"

android:layout_width = "wrap_content"

android:layout_heigth = "wrap_content"/>

final Chronometer ch = (Chronometer)findViewById(R.id.chronometer1);

ch.setOnChronometer(SystemClock.elapsedReadtime());

ch.setFormat("use time:%s");

ch.start();

ch.setOnChronometerTickListener(new OnChronometerTickListener(){

@override

public void onChronometerTick(Chronometer chronometer){

if(SystemClock.elapsedRealtime()-ch.getBase()>=10000){

ch.stop();

}

}

});

14.example

e.g.1 ImageButton with Mouse Click

@.xml

android:src = "@drawable/button_state"

android:background = “#0000”  

（As usual,ImageButton will come with grey background,#0000 means black Transparent） 

@button_state.xml

<?xml version = "1.0" encoding = "utf-8">

<selector

      xmlns:android:"http://schemes.android.com/apk/res/android">

<item android:state_pressed = "true" android:drawable = "@drawable/start_b"/>

<item android:state_pressed = "false" android:drawable = "@drawable/start_a"/>

</selector>

e.g.2 ListView with icon

@.xml

<?xml version = "1.0" encoding = "utf-8">

<LinearLayout

      xmlns:android:"http://schemes.android.com/apk/res/android"

      android:orientation = "horizontal"

android:adjustViewBounds = "true"

android:maxWidth = "72px"

android:maxHeight = "72px"

  android:layout_height = "wrap_content"/>

<TextView

android:layout_width = "wrap_content"

  android:layout_height = "wrap_content"

android:padding = "10px"

android:layout_gravity = "center"/>

</LinearLayout>

}

SimpleAdapter adapter = new SimpleAdapter(this,listItems,

R.layout.items,new String[]{"title","image"},new int[]{R.id.title,R.id.image});

listView.setAdapter(adapter);

e.g.3 (3 shoes)

image1.setImageDrawable(getResources().getDrawable(imageIds[0]));

image1.setAlpha(100);            //set alpha value

int[] imageIds = new int[] { R.drawabe.shoe_ok,R.drawable.shoe_sorry,
