Question

以下是我在测试的代码，当我给任何特定小部件充气时，我不能真正对它进行setText。它会覆盖文本并返回最后一个字符串。在输出屏幕中，我可以看到从xml添加的五个textview但是我试图设置的一个没有发生我只看到str []中的一个文本，即str [5]，这是数组中的最后一个。如果我能够解释我的问题，请告诉我。

public class TestInflate extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    View[] inflated = new View[5];
    for(int i = 0; i<5; i++)
    {
        TableLayout myTableLayout = (TableLayout)findViewById(R.id.TableLayout);
        LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        inflated[i] = inflater.inflate(R.layout.testbutton, myTableLayout);

        TextView userName = (TextView)inflated[i].findViewById(R.id.myName);
        userName.setText(str[i]);//here i should get name but not getting
    }
}
String[] str = {"a","s","d","r","t"};
}

我的testButton.xml如下

<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/TableRow"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true">
<TextView
android:id="@+id/Name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10px"
android:text="Name   :"
android:textStyle="bold"
android:layout_weight=".25"
></TextView>
<TextView
android:id="@+id/myName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="italic"
android:layout_weight=".5"
></TextView>
</TableRow>

和main.xml是

 <ScrollView
 android:id="@+id/Scroll"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 xmlns:android="http://schemas.android.com/apk/res/android">  
<TableLayout
 android:id="@+id/TableLayout"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:orientation="vertical"
 android:clickable="true">
   </TableLayout>
   </ScrollView>

编辑和输入就像这样

My output is like this 
Name : t //str[5]  
Name : 
Name : 
Name :  
Name :

这次它经过测试。试试这个。

public class MainActivity extends Activity {
    /** Called when the activity is first created. */
    String[] str = {"a","s","d","r","t"};


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TableLayout myTableLayout = (TableLayout)findViewById(R.id.TableLayout);
        LayoutInflatedView myClasses [] = new LayoutInflatedView[5];
        for(int i = 0; i<5; i++)
        {
           myClasses[i] = new LayoutInflatedView(this, myTableLayout);
           myTableLayout.addView(myClasses[i]);
           myClasses[i].setUserName(str[i]);

        }


    }
}

您的LayoutInflatedView是：

public class LayoutInflatedView extends LinearLayout
{
    TextView text;    
    public LayoutInflatedView(Context context, ViewGroup table)
    {
        super(context);        
        LayoutInflater layoutInflater =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view=layoutInflater.inflate(R.layout.test_button,this);
        text = (TextView)findViewById(R.id.myName);
    }
    public void setUserName(String text)
    {
        this.text.setText(text);
    }

}

检查此项并告知我们是否出现任何问题。

Answer 2

LayoutInflater layoutInflater = 
      (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    final View addView = layoutInflater.inflate(R.layout.row, null);
    TextView textOut = (TextView)addView.findViewById(R.id.textout);
    textOut.setText(textIn.getText().toString());
    Button buttonRemove = (Button)addView.findViewById(R.id.remove);
    buttonRemove.setOnClickListener(new OnClickListener(){

     @Override
     public void onClick(View v) {
      ((LinearLayout)addView.getParent()).removeView(addView);
     }});

    container.addView(addView);

你也可以在你的for循环中尝试这个。供参考：Look Here

setText（）不适用于膨胀的文本视图
