Creating dialog in java/android

Question

I am trying to create an error dialog that says "Wrong input : input". My problem - "Wroing input" is pre-defined in the string file and thus have R.string.error int number. The "input" is dynamic and I can only obtain it in runtime. the setMessage() method can work with either a char sequence or an int (for id), so how can I concat it? Hope I was clear, thanks!

Answer 1

You can call getString to obtain the string from the xml:

String msg = getString(R.string.error) + myDynamicStringMessage;

Note that getString is a context method, so make sure to call it from one.

Answer 2

如果我对您的理解正确，那么您应该能够创建一个String变量，其中“错误的输入”和“ input”已连接在一起，然后只需将该String传递给setMessage（）方法即可。

Answer 3

Use getString() to obtain string from xml

you can use setMessage(getString(R.string.error)+" My Dynamic Message")

Example

new AlertDialog.Builder(this).setMessage(getString(R.string.error)+" My Dynamic Message")
        .setPositiveButton("YES", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub
                finish();
            }
        }).setNegativeButton("NO", null).show();
