如何将setText（）移动到Android Studio上的新活动？

-2

我打算做一个篮子，并希望取决于按下哪个按钮，屏幕上显示的价格然后出现在TextView09（表的部分）的篮子（新活动）中，但此时出现的是android.support.v7.widget.App ...如何将setText（）移动到Android Studio上的新活动？

下面是该产品的活动页面：

package com.example.emily.woodensigns; 

import android.content.Intent; 
import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.TextView; 
import android.view.LayoutInflater; 


public class Letters extends AppCompatActivity { 
    int txtSize = 14; 
    EditText Wood; 
    Button bSize, bSize1, bSize2, bSize3, bBasket; 
    public int count = 5; 
    private LayoutInflater mInflater; 

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

     Wood = (EditText) findViewById(R.id.Wood); 
     Button bSize = (Button) findViewById(R.id.bSize); 
     Button bSize1 = (Button) findViewById(R.id.bSize1); 
     Button bSize2 = (Button) findViewById(R.id.bSize2); 
     Button bSize3 = (Button) findViewById(R.id.bSize3); 
     Button bBasket = (Button) findViewById(R.id.bBasket); 
     final TextView price = (TextView) findViewById(R.id.price); 


     bSize.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Wood.setTextSize(40); 
       price.setText("£10"); 
       TextView price = (TextView) findViewById(R.id.price); 
       String pri = price.getText().toString(); 
       Intent intent2 = new Intent(Letters.this, Letters.class); 
       intent2.putExtra("£",pri); 

      } 
     }); 
     bSize1.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Wood.setTextSize(60); 
       price.setText("£20"); 
      } 
     }); 
     bSize2.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Wood.setTextSize(100); 
       price.setText("£35"); 
      } 
     }); 
     bSize3.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Wood.setTextSize(150); 
       price.setText("£50"); 
      } 
     }); 


     bBasket.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       EditText Wood = (EditText) findViewById(R.id.Wood); 
       String str = Wood.getText().toString(); 
       if (str.length() == 0) { 
        Wood.requestFocus(); 
        Wood.setError("FIELD CANNOT BE EMPTY"); 
       } else if (str.length() >= 2) { 
        Wood.requestFocus(); 
        Wood.setError("You can only type one letter!"); 
       } else { 
        Intent intent2 = new Intent(Letters.this, Basket.class); 
        intent2.putExtra("MY_INFO",str + " - Letters" + price); 
        startActivity(intent2); 
       } 
      } 
     }); 
    } 
}

活动为篮：

package com.example.emily.woodensigns; 

import android.content.Intent; 
import android.os.Bundle; 
import android.support.design.widget.FloatingActionButton; 
import android.support.design.widget.Snackbar; 
import android.support.v7.app.AppCompatActivity; 
import android.support.v7.widget.Toolbar; 
import android.view.View; 
import android.widget.Button; 
import android.widget.TextView; 
import android.widget.EditText; 
import android.widget.Toast; 
import android.util.Log; 


public class Basket extends AppCompatActivity { 


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

     TextView TextView08 = (TextView) findViewById(R.id.TextView08); 
     TextView TextView09 = (TextView) findViewById(R.id.TextView09); 
     Button bCheckout=(Button) findViewById(R.id.bCheckout); 

     String strFromActivity = getIntent().getStringExtra("MY_INFO"); 
     TextView08.setText(strFromActivity); 

     String priFromActivity = getIntent().getStringExtra("£"); 
     TextView09.setText(priFromActivity); 
     Toast.makeText(getBaseContext(),priFromActivity, Toast.LENGTH_LONG).show(); 

     bCheckout.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       Intent intent2 = new Intent(Basket.this, customerDetails.class); 
       startActivity(intent2); 
      } 
     }); 
    } 
}

你需要拿应用变量 –

出现什么？ –

@ShreeKrishna表中，而不是价格买过它的文件名称，它说android.support.v7.widget.App ....我不能读其余的，因为它不适合在表中。这是出现在我想要的价格相同的地方。 – 09Emi

你BTN点击代码应该如下所示：

bBasket.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       EditText Wood = (EditText) findViewById(R.id.Wood); 
       String str = Wood.getText().toString(); 
       if (str.length() == 0) { 
        Wood.requestFocus(); 
        Wood.setError("FIELD CANNOT BE EMPTY"); 
       } else if (str.length() >= 2) { 
        Wood.requestFocus(); 
        Wood.setError("You can only type one letter!"); 
       } else { 
        Intent intent2 = new Intent(Letters.this, Basket.class); 
        intent2.putExtra("MY_INFO",str + " - Letters" + price); 
        TextView price = (TextView) findViewById(R.id.price); 
        String pri = price.getText().toString(); 
        intent2.putExtra("£",pri); 
        startActivity(intent2); 
       } 
      } 
     });

希望这会帮助你。

谢谢你的回答，但你知道如何让价格真正进入表格，而不是只出现在教科书中，然后消失。 – 09Emi

@ 09Emi，你可以传递空白值，intent2.putExtra（“£”，“”）; –

感谢它的工作，你知道如果表中的第一行是完整的如何把它放在下一行？ – 09Emi
