未存储的EditText vlaue在字符串 [英] Not storing the EditText vlaue in a string

问题描述

我有在存储在一个字符串编辑文本能值的问题。我只是想用来存储用户输入其存储在某些变量的值。我用吐司只是存储的值后检查值是否在IT卖场或不和烤面包不显示任何值。我尝试以下code，但没有找到它的帮助。

 包com.example.electropollsys;进口android.annotation.Sup pressLint;
进口android.app.Activity;
进口android.content.Intent;
进口android.os.Bundle;
进口android.view.View;
进口android.view.Window;
进口android.view.WindowManager;
进口android.widget.Button;
进口android.widget.EditText;
进口android.widget.TextView;
进口android.widget.Toast;公共类CreateAcc延伸活动{
    保护无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
    requestWindowFeature（Window.FEATURE_NO_TITLE）;
     this.getWindow（）。setFlags（WindowManager.LayoutParams.FLAG_FULLSCREEN，
             WindowManager.LayoutParams.FLAG_FULLSCREEN）;     的setContentView（R.layout.create_acc）;     最后键b =（按钮）findViewById（R.id.button3）;
     b.setOnClickListener（新View.OnClickListener（）{
         公共无效的onClick（视图v）{             意图I =新意图（CreateAcc.this，SignIn.class）;
            i.addFlags（
                Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_NEW_TASK）;
                startActivity（ⅰ）;
         }
     }）;     最终按钮=（按钮）findViewById（R.id.button1）;
     a.setOnClickListener（新View.OnClickListener（）{
            @燮pressLint（ShowToast）
            公共无效的onClick（视图v）{                EditText上输入1 =（EditText上）findViewById（R.id.fname1）;
                。字符串FNAME = input1.getEditableText（）的toString（）;                EditText上输入2 =（EditText上）findViewById（R.id.lname1）;
                。字符串LNAME = input2.getEditableText（）的toString（）;                Toast.makeText（CreateAcc.this，......+ FNAME +......，Toast.LENGTH_LONG）;
                Toast.makeText（CreateAcc.this，......+ LNAME +......，Toast.LENGTH_LONG）;              }
         }）;
    }
    }
 

解决方案

尝试：

  Toast.makeText（CreateAcc.this，......+ FNAME +......，Toast.LENGTH_LONG）.show（）;
Toast.makeText（CreateAcc.this，......+ LNAME +......，Toast.LENGTH_LONG）.show（）;
 

敬酒不显示，除非显示（）方法被调用。在 makeText（）方法返回一个吐司对象，则必须使用显示敬酒。

您通常会得到关于这个皮棉警告，但你似乎有燮$ P $与 @燮pressLint（ShowToast）pssed它。

I am having a problem in storing a Edit able Text value in a string. I just want to store a value that user enter store it in some variable. i used toast just after storing a value to check whether the value is store in it or not and toast doesn't show any value. i try the following code but didnt find it helpful.

    package com.example.electropollsys;

import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;



public class CreateAcc extends Activity {
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);


    requestWindowFeature(Window.FEATURE_NO_TITLE);
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,  
             WindowManager.LayoutParams.FLAG_FULLSCREEN);

     setContentView(R.layout.create_acc);

     final Button b = (Button) findViewById(R.id.button3);
     b.setOnClickListener(new View.OnClickListener() {
         public void onClick(View v) {

             Intent i = new Intent(CreateAcc.this, SignIn.class);
            i.addFlags(
                Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(i);
         }


     });

     final Button a = (Button) findViewById(R.id.button1);
     a.setOnClickListener(new View.OnClickListener() {


            @SuppressLint("ShowToast")
            public void onClick(View v){

                EditText input1= (EditText)findViewById(R.id.fname1); 
                String fname = input1.getEditableText().toString();

                EditText input2= (EditText) findViewById(R.id.lname1); 
                String lname = input2.getEditableText().toString();

                Toast.makeText(CreateAcc.this,"...."+fname+"...." , Toast.LENGTH_LONG);
                Toast.makeText(CreateAcc.this,"...."+lname+"...." , Toast.LENGTH_LONG);

              }
         });
    }
    }

解决方案

Try:

Toast.makeText(CreateAcc.this,"...."+fname+"...." , Toast.LENGTH_LONG).show();
Toast.makeText(CreateAcc.this,"...."+lname+"...." , Toast.LENGTH_LONG).show();

Toasts do not show unless the show() method is called. the makeText() method returns a Toast object which you must use to display the toast.

You normally get a lint warning about this, but you seem to have suppressed it with @SuppressLint("ShowToast").
