Question

在我的代码中，当我选择if- elseIf语句中提到的选项时，我想立即关闭警报对话框并启动活动。我不想要和取消按钮。我的代码工作正常（语句内部如果语句有效，但警告对话仍然存在）。谢谢你的帮助

final AlertDialog.Builder builder =
    new AlertDialog.Builder(arg0.getContext());
builder.setTitle("Favourities Management");
// TODO Auto-generated method stub
int selected = 0;

builder.setSingleChoiceItems(values, selected, new DialogInterface.OnClickListener() {

    @
    Override
    public void onClick(DialogInterface dialog, int which) {
        if (values[which] == "Select Benificiary") {
            Intent registerUser = new Intent(FinalUtilityBillPayment.this, ListViewBeneficiaryBillPayment.class);
            FinalUtilityBillPayment.this.startActivity(registerUser);
            startActivityForResult(registerUser, 1);
        } else if (values[which] == "Add Benificiary") {
            try {
                mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE, null);
                mydb.execSQL("CREATE TABLE IF  NOT EXISTS " + TABLE + " (ID INTEGER PRIMARY KEY, ReferenceNo TEXT, Mobile Text);");

                mydb.close();
            } catch (Exception e) {
                Toast.makeText(getApplicationContext(), "Error in creating table", Toast.LENGTH_LONG).show();
            }
            try {
                mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE, null);
                mydb.execSQL("INSERT INTO " + TABLE + "(ReferenceNo, Mobile) VALUES('" + ref.getText().toString() + "','" + mob.getText().toString() + "')");
                mydb.close();
            } catch (Exception e) {
                Toast.makeText(getApplicationContext(), "Error in inserting into table", Toast.LENGTH_LONG).show();
            }
        } else if (values[which] == "Delete Benificiary") {

            Intent registerUser = new Intent(FinalUtilityBillPayment.this, ListViewDeleteBeneficiaryBillPayment.class);
            //startActivityForResult(registerUser, 1);
            FinalUtilityBillPayment.this.startActivity(registerUser);

Answer 2

您必须关闭警报对话框。试试这个：

Dialogue.dismiss();

Answer 3

试试这个... onClick()您可以看到DialogInterface dialog该对话框名称。

在调用其他活动之前使用此dialog.cancel();

dialog.cancel();

    Intent registerUser = new Intent(FinalUtilityBillPayment.this,ListViewBeneficiaryBillPayment.class);
    //FinalUtilityBillPayment.this.startActivity(registerUser);    
    startActivityForResult(registerUser, 1);

Answer 4

调用.dismiss（）来关闭它，也可以使用简单的Dialog来为它设置自定义布局

Dialog alert = new Dialog(context);
alert.setContentView(layoutResID);

android中的警报对话框
