Question

大家好我有一个带有两个文本框的警告框，这里的问题是当用户点击弹出窗口之外时警报对话框消失，或者当用户点击确定按钮时警报对话框消失。

所以请在这方面帮助我提前谢谢......

final AlertDialog.Builder builder=new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Sign In Failed");
final EditText input1=new EditText(MainActivity.this);
final EditText input2=new EditText(MainActivity.this);
input1.setHint("eNTER name1");
input2.setHint("Enter Name2");
LinearLayout linearLayout= new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
builder.setMessage("Invalid username or password");
linearLayout.addView(input1);
linearLayout.addView(input2);
builder.setView(linearLayout);
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        dialog.cancel();
    }
});
builder.show();

Answer 1

你需要设置外部触摸假试试这个：

setCanceledOnTouchOutside(false);

Answer 2

只需设置cancelable false：

.setCancelable(false)

Answer 3

因为默认情况下它是可取消的

在builder.setView（linearLayout） -

之后添加

builder.setCancelable(false);

<强>更新

根据您的代码段 -

builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        dialog.cancel();
    }
});

在正面按钮上（＆＃34;确定＆＃34;）点击，您正在设置dialog.cancel()不要这样做，您应该按照正面按钮点击的要求设置一些操作。

请参阅：

builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel(); // close the current dialog
        }
    });

builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

           //Perform any Intent Action or perform validation as you want

         }
    });

更新2

只需复制＆amp;粘贴下面的代码 - 完美地工作

 final EditText input1 = new EditText(MainActivity.this);
        final EditText input2 = new EditText(MainActivity.this);
        input1.setHint("Enter name1");
        input2.setHint("Enter Name2");
        LinearLayout linearLayout = new LinearLayout(this);
        linearLayout.setOrientation(LinearLayout.VERTICAL);
        linearLayout.addView(input1);
        linearLayout.addView(input2);

        final AlertDialog builder = new AlertDialog.Builder(MainActivity.this)
                .setTitle("Sign In Failed")
                .setCancelable(false)
                .setMessage("Invalid username or password").setView(linearLayout).setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                    }
                }).create();
        builder.show();
        builder.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (input1.length() <= 0) {
                    Toast.makeText(MainActivity.this, "Please Enter Name", Toast.LENGTH_SHORT).show();

                } else {
                    Toast.makeText(MainActivity.this, "OK", Toast.LENGTH_SHORT).show();
                    builder.dismiss();
                }
            }
        });

当用户点击一侧时，警报对话框正在消失
