Android事件汇总

 

1  RadioGroup控件的OnCheckedChangeListener 事件 

 

  /* RadioGroup用OnCheckedChangeListener来运行 */
   mRadioGroup1.setOnCheckedChangeListener(mChangeRadio);

  private RadioGroup.OnCheckedChangeListener mChangeRadio = new RadioGroup.OnCheckedChangeListener() {
		@Override
		public void onCheckedChanged(RadioGroup group, int checkedId) {
	 
			if (checkedId == mRadio1.getId()) {
				/* 把mRadio1的内容传到mTextView1 */
				mTextView1.setText(mRadio1.getText());
				myTextViewKeyListener.setTag("show soft key ");
			} else if (checkedId == mRadio2.getId()) {
				/* 把mRadio2的内容传到mTextView1 */
				mTextView1.setText(mRadio2.getText());
				myTextViewKeyListener.setTag(null);
			}
		}
	};

 2  EditText.OnKeyListener 监听机制 

 

   

 myTextViewKeyListener.setOnKeyListener( new EditText.OnKeyListener(){
	@Override
	public boolean onKey(View v, int keyCode, KeyEvent event) {

		mTextView1.setText(myTextViewKeyListener.getText().toString()  );
		return false;
	}
});

 

3  复选框的CompoundButton.OnCheckedChangeListener监听事件 

  

checkboxBaskball = (CheckBox) findViewById(R.id.basketball);
checkboxFootball.setOnCheckedChangeListener( new MyCheckBoxListener());

private class MyCheckBoxListener implements   OnCheckedChangeListener{

@Override
public void onCheckedChanged(CompoundButton buttonView,
		boolean isChecked) {
	 if(isChecked){
		 Toast.makeText(RadioGroupActivity.this, "您选择了："+buttonView.getText(),Toast.LENGTH_SHORT).show() ; 
	 }else{
		 Toast.makeText(RadioGroupActivity.this, "您取消选择了："+buttonView.getText(),Toast.LENGTH_SHORT).show() ; 
	 }
	
}
}

 

 

4  按钮的单击事件 

myButton1.setOnClickListener(new Button.OnClickListener(){  
	@Override  
	public void onClick(View v) {  
	}             
});  

 4 Spinner 的 AdapterView.OnItemSelectedListener事件 

  

	
	 private Spinner spinner;    
	 private ArrayAdapter<String> adapter;  
	 private static final String[] m={"足球","篮球","排球","乒乓球","冰球"};   


    public void useSpinner(){
	   spinner = (Spinner) findViewById(R.id.Spinner01);  
	   //将可选内容与ArrayAdapter连接起来  
       adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,m);  
       //设置下拉列表的风格  
       adapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item);  
       spinner.setAdapter(adapter); 
       spinner.setPrompt("请选择人名");  
       //设置默认选择项  
       spinner.setVisibility(View.VISIBLE); 
       //设置监听器  
       spinner.setOnItemSelectedListener(new SpinnerSelectedListener());
       
	}


    //spinner 选择监听器   
    class SpinnerSelectedListener  implements  AdapterView.OnItemSelectedListener{  
  
        @Override  
        public void onItemSelected(AdapterView<?> arg0, View arg1, int index,  
                long arg3) {  
        	Toast.makeText(RadioGroupActivity.this, "您选择了："+arg0.getItemAtPosition(index).toString(),Toast.LENGTH_SHORT).show() ;
        }  
  
        @Override  
        public void onNothingSelected(AdapterView<?> arg0) {  
        }  
          
    } 

 

 5 时间和日期的DatePickerDialog.OnDateSetListener 和TimePickerDialog.OnTimeSetListener 监听器

  

        final Calendar c = Calendar.getInstance();
        mYear = c.get(Calendar.YEAR);  
        mMonth = c.get(Calendar.MONTH);  
        mDay = c.get(Calendar.DAY_OF_MONTH);
        
        mHour = c.get(Calendar.HOUR_OF_DAY);
        mMinute = c.get(Calendar.MINUTE);


            MyDatePickerDialog myDatePickerDialog = new MyDatePickerDialog();
            DatePickerDialog datePickerDialog = new DatePickerDialog(this, 
                    myDatePickerDialog,mYear, mMonth, mDay);
            datePickerDialog.show(); 


            MyTimePickerDialog myTimePickerDialog = new MyTimePickerDialog();
            TimePickerDialog timePickerDialog = new TimePickerDialog(this, 
                    myTimePickerDialog, mHour, mMinute, true);
            timePickerDialog.show();            //显示时间设置对话框

    /*
     * Function  :       自定义MyDatePickerDialog类，用于实现DatePickerDialog.OnDateSetListener接口，
     *       当点击日期设置对话框中的“设置”按钮时触发该接口方法
     */
    public class MyDatePickerDialog implements DatePickerDialog.OnDateSetListener {
        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            mYear = year;  
            mMonth = monthOfYear;  
            mDay = dayOfMonth;  
            
            updateDateDisplay(); 
        }
    }
     
    /*
     * Function  :  自定义MyTimePickerDialog类，用于实现TimePickerDialog.OnTimeSetListener接口，
     *                           当点击时间设置对话框中的“设置”按钮时触发该接口方法
     */
    public class MyTimePickerDialog implements TimePickerDialog.OnTimeSetListener {
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
			mHour = hourOfDay;
			mMinute = minute;
			updateTimeDisplay();
        }     
    }

 

 6 进度条使用 

    1） 设置进度条模式，setIndeterminate 是否为模糊模式，true：不显示进度条进度   false：显示进度条进度。

    2 ）设置最大进度值   setMax 

    3）设置现在进度值 setProgress

    

	<ProgressBar 
		android:id="@+id/message_detail_head_progress" 
		android:layout_gravity="left|center"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content"
		style="@android:style/Widget.ProgressBar.Horizontal"
		/>

	<ProgressBar 
		android:id="@+id/message_detail_head_progress2" 
		android:layout_gravity="left|center"
				android:layout_width="wrap_content"
		android:layout_height="wrap_content"
		style="@android:style/Widget.ProgressBar.Small"
		/>
