Android开发笔记

1.运用AlertDialog.Builder 对话框自定义view，并经过setview设置
AlertDialog.Builder dlgAlert;
dlgAlert = new AlertDialog.Builder(this);
LayoutInflater inflater = getLayoutInflater();
dlgAlert.setTitle(“用户协议”); //dlgAlert.setMessage(R.string.agreement); View checkView=inflater.inflate(R.layout.agreedialogview,null);
dlgAlert.setView(checkView);
CheckBox agreeCheck=(CheckBox)checkView.findViewById(R.id.checkBox_agree);;
dlgAlert.setPositiveButton(“确认”, new DialogInterface.OnClickListener() {
@Override public void onClick(DialogInterface dialog, int id) { // if this button is clicked, close current activity if (agreeCheck.isChecked()) {
init();
} else {
finish();
System.exit(0);
}
}
}).create();
dlgAlert.setNeutralButton(“退出”, new DialogInterface.OnClickListener() {
@Override public void onClick(DialogInterface dialog, int id) { // if this button is clicked, close current activity finish();
System.exit(0);
}
}).create();
dlgAlert.show();
这儿要想在对话框按钮的监听事情中调用xml布局里面的控件，不能直接findViewById，需求这样写
View checkView=inflater.inflate(R.layout.agreedialogview,null);
dlgAlert.setView(checkView);
CheckBox agreeCheck=(CheckBox)checkView.findViewById(R.id.checkBox_agree);;
对话框.show()函数之后才能够调用，
