如何解决来自公共类的 AlertDialogs
我正在浏览我在 2014 年编写的一个 Android 应用程序,并且正在用 AlertDialogs 替换 Dialogs
以前,我一直使用以下对话框代码创建一个弹出窗口(从此弹出窗口),该弹出窗口将在选择“清除表”时出现,并警告用户他们的操作结果。
public class locationPopupWindow {
Context ctx;
Button btndismiss,btnSaveRecord,btnPurgeTable,btnUpdateRecord,btnDeleteRecord,btnClearForm,btnFirstRecord,btnPrevIoUsRecord,btnNextRecord,btnLastRecord;
public locationPopupWindow(Context ctx){
this.ctx = ctx;
}
public void init(){
LayoutInflater inflater = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View popUpView = inflater.inflate(R.layout.location_popup_layout,null,false);
final PopupWindow popup = new PopupWindow(popUpView,ViewGroup.LayoutParams.WRAP_CONTENT,true);
popup.setContentView(popUpView);
...
btnPurgeTable=(Button)popUpView.findViewById(R.id.btnPurgeTablexml);
btnPurgeTable.setonClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){
vibrate(100);
openRedDialog();
}
});
}
private void openRedDialog() {
final Dialog redDialog = new Dialog(this.ctx,android.R.style.Theme_Translucent);
redDialog.setCancelable(true);
redDialog.setContentView(R.layout.red_dialog);
TextView tvRedDialogBody = (TextView)redDialog.findViewById(R.id.tvRedDialogtitle);
tvRedDialogBody.setTypeface(null,Typeface.BOLD);
tvRedDialogBody.setText(" Are you really sure you want to permanently delete your data???");
Button btnDeleteTable = (Button) redDialog.findViewById(R.id.btndeletetable);
Button btnCancel = (Button)redDialog.findViewById(R.id.btncanceldelete);
btnDeleteTable.setonClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
vibrate(100);
purgeTable();
redDialog.dismiss();
Toast.makeText(ctx.getApplicationContext(),"Lookup table was purged. Please add new values.",Toast.LENGTH_LONG).show();
}
});
btnCancel.setonClickListener(new View.OnClickListener(){
@Override
public void onClick(View view){
vibrate(100);
redDialog.dismiss();
}
});
new CountDownTimer(5000,1000) {
@Override
public void onTick(long millisUntilFinished) {
}
@Override
public void onFinish() {
redDialog.dismiss();
}
}.start();
redDialog.show();
}
...
}
我已经交换了 openRedDialog() 的以下 AlertDialog 实现,
private void openRedDialog(Context context) {//uses context
AlertDialog openRedDialog = new AlertDialog.Builder(context).create();
openRedDialog.setTitle("Warning");
openRedDialog.setMessage("This will delete the whole table");
openRedDialog.setButton(AlertDialog.BUTTON_NEUTRAL,"Cancel",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
dialog.dismiss();
}
});
openRedDialog.setButton(AlertDialog.BUTTON_POSITIVE,"Delete Table",int which) {
purgeTable();
dialog.dismiss();
}
});
openRedDialog.show();
}
效果很好。
问题:当我如上实现 AlertDialog 时,如何扩充我的 .xml 资源? 提前致谢...
解决方法
加上这个,
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.red_dialog,null);
为了得到这个,
private void openRedDialog(Context context) {
AlertDialog openRedDialog = new AlertDialog.Builder(context).create();
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.red_dialog,null);
在视图中包含 xml。
