Android点击返回键back时弹出对话框Dialog

1监听返回键 public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) { ExitDialog(MainActivity.this).show(); return true; } return super.onKeyDown(keyCode, event); } 2创建一个Dialog对话框方法 private Dialog
ExitDialog(Context context) { AlertDialog.Builder builder = new AlertDialog.Builder(context); builder.setIcon(R.drawable.icon); builder.setTitle("弹出对话框"); builder.setMessage("确定要××××吗，O(∩_∩)O哈哈~"); builder.setPositiveButton("确定", new DialogInterface.OnClickListener()
{ public void onClick(DialogInterface dialog, int whichButton) { //××××操作代码 } }); builder.setNegativeButton("取消", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { } }); return builder.create(); }
