按下按钮提示

Question

我目前正在开发一款允许用户注册并输入 his/her 详细信息的应用程序。我想在用户按下提交按钮后显示 "Successfully Registered!" 提示或消息，以便用户知道输入的详细信息 he/she 已提交。

这是我的提交按钮：

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register);

        Intent recvdIntent = getIntent();
        mUsername = recvdIntent.getStringExtra("USERNAME");
        mUsername = recvdIntent.getStringExtra("PASSWORD");

        Button btnSubmit = (Button) findViewById(R.id.btn_submit);
        btnSubmit.setOnClickListener(

                new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        submitUserData();
                        return;
                        }
        }
    );

AlertDialog

public void showAlertDialog(String title,String msg){


    AlertDialog alertDialog = new AlertDialog.Builder(
            AlertDialogActivity.this)
            .setTitle(title)  // Setting Dialog Title
            .setMessage(msg)// Setting Dialog Message
            .setCancelable(false)
            .create();

        // Setting OK Button
        alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                // Write your code here to execute after dialog closed
                Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
                }
        });


    // Showing Alert Message
    alertDialog.show();

}

试试这个：

final AlertDialog.Builder builder = new AlertDialog.Builder(SignupActivity.this);
builder.setCancelable(false);
builder.setTitle("Success");
builder.setMessage("Successfully registered, Sign in now");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        Intent intent = new Intent(SignupActivity.this, TargetActivity.class);
        startActivity(intent);
        finish();
    }
});
builder.show();

您可以通过多种方式完成，

警报对话框
吐司
弹出对话框

让我们使用警报对话框来完成。

AlertDialog alertDialog = new AlertDialog.Builder(
                        AlertDialogActivity.this).create();

        // Setting Dialog Title
        alertDialog.setTitle("Alert Dialog");

        // Setting Dialog Message
        alertDialog.setMessage("Welcome");

        // Setting Icon to Dialog
        alertDialog.setIcon(R.drawable.tick);

        // Setting OK Button
        alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                // Write your code here to execute after dialog closed
                Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
                }
        });

        // Showing Alert Message
        alertDialog.show();
