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" />
Activity
public class ProgressBarActivity extends Activity {
protected static final int GUI_STOP_NOTIFIER = 0x108;
protected static final int GUI_THREADING_NOTIFIER = 0x109;

myProgress1 = (ProgressBar) findViewById(R.id.message_detail_head_progress);
myProgress2 = (ProgressBar) findViewById(R.id.message_detail_head_progress2);
myButton = (Button) findViewById(R.id.Button06);

// 通过线程来改变Progress的值

// Thread.currentThread().interrupt();
}
break;
}
super.handleMessage(msg);
}
};
