1.該效果是當按返回按鈕時彈出一個提示,來確保無誤操做,採用常見的對話框樣式。android
建立dialog對話框方法代碼以下:web
01 |
protected void dialog() { |
02 |
AlertDialog.Builder builder = new Builder(Main. this ); |
03 |

05 |
builder.setPositiveButton( "確認" , new OnClickListener() { |

12 |
builder.setNegativeButton( "取消" , new OnClickListener() { |
14 |
public void onClick(DialogInterface dialog, int which) { |
18 |
builder.create().show(); |
在onKeyDown(int keyCode, KeyEvent event)方法中調用此方法
ide

public boolean onKeyDown( int keyCode, KeyEvent event) { |
2 |
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0 ) { |

04 |
android:layout_height = "wrap_content" android:layout_width = "wrap_content" |
05 |
android:background = "#ffffffff" android:orientation = "horizontal" |
06 |
android:id = "@+id/dialog" > |
07 |
< TextView android:layout_height = "wrap_content" |
