EditText不返回到ListView

Question

我有两个活动，A和B.在A，它有一个listView和button。在B中，它有imageView和editText。现在我想实现的是从B文本返回listView A.

活动A

View claims = inflater.inflate(R.layout.receipt_text, container, false); 
    listV = (ListView) claims.findViewById(R.id.listView); 
    String [] status ={"Type of Claims :" +name,"Amount :" +result}; 

    adapter=new ArrayAdapter<String>(this,R.layout.claims,status); 
    listV.setAdapter(adapter); 

    return claims; 
    } 

    @Override 
    public void onActivityResult(int requestCode, int resultCode, Intent data) { // receive text from B 

     switch (requestCode) { 
       case 0: 
        result = data.getStringExtra("text"); 
        name = data.getStringExtra("a"); 
        description = data.getStringExtra("c"); 

        break; 
} 

活动B

ImageView viewImage; 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.project); 
     txt = (EditText) findViewById(R.id.editText36); 
     txt1=(TextView)findViewById(R.id.textView57); 
     Button b = (Button) findViewById(R.id.button17); 
     addListenerOnButton(); 

     b.setOnClickListener(new View.OnClickListener() { // return to A 
        public void onClick(View arg0) { 
         Intent returnIntent = new Intent(); 
         a = "Project"; 
         text = txt.getText().toString(); // amount 
         returnIntent.putExtra("text", text); 
         returnIntent.putExtra("a", a); 
         returnIntent.putExtra("c", c); 
         setResult(Activity.RESULT_OK, returnIntent); 
         finish(); 
        } 
       }); 

     public void addListenerOnButton() { 
     imageButton = (ImageButton) findViewById(R.id.imageButton); 
     imageButton.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 
       Global.img=null; 
       Intent i = new Intent(Project1.this, C.class); 
       startActivityForResult(i, PROJECT_REQUEST_CODE); 
      } 

     }); 

    } 

    public void onActivityResult(int requestCode,int resultCode, Intent data) 
    { // receive from C 
     if(requestCode==PROJECT_REQUEST_CODE) { 
      if(data!=null&&data.hasExtra("text")) { 
       c = data.getStringExtra("text"); 
       txt1.setText(c); 
       viewImage.setImageBitmap(Global.img); 
      } 


     } 
     else if (requestCode==CAMERA_REQUEST_CODE) 
     { 

     } 
    } 

} 

receipt_text.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" android:layout_height="fill_parent"

    <TextView android:layout_width="fill_parent" 
     android:layout_height="wrap_content" android:padding="10dp" 
     android:text="@string/text" android:textSize="20sp" /> 

    <TextView 
     android:id="@+id/textView" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" > 
    </TextView> 

    <ListView android:id="@+id/listView1" android:layout_width="fill_parent" 
     android:layout_height="fill_parent" /> 

</LinearLayout> 

claims.xml

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/drawer_layout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <TextView 
     android:id="@+id/textView1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentTop="true" 
     android:textAppearance="?android:attr/textAppearanceMedium" /> 

</android.support.v4.widget.DrawerLayout>

Answer 1

ArrayAdapter的构造函数是错误的。

adapter=new ArrayAdapter<String>(this,R.layout.claims,c); 

不是传递一个int到一个ArrayAdapter的构造函数，创建一个列表，并通过它在后来加你从活动B到列表中的数据。

List<String> list = new ArrayList<>(); 
adapter=new ArrayAdapter<String>(this, R.layout.claims, list); 

当你从ActivityB取回数据，这样做

String data = Integer.toString(c); 
list.add(data); 
adapter.notifyDataSetChanged();
