TableLayout中的TextView數組

我想做4列動態更改數據行。我會用LinearLayout來做到這一點，但我找不到一個好方法來獲得一組4 x textview。這是名爲.java其trowing在底部列出一個致命的錯誤：TableLayout中的TextView數組

public class DebtList extends Activity { 

Integer trigger = 5; 
Double totalDebt = 0.00; 

@TargetApi(Build.VERSION_CODES.HONEYCOMB) 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.debtlist); 

    //Bundle extras = getIntent().getExtras(); 

    String[] debtNames = new String[10]; 
    Double[] debtAmount = new Double[10]; 
    Double[] debtRate = new Double[10]; 
    Double[] debtTerm = new Double[10]; 

    Integer stopper = trigger+1; 

    TableLayout tl=(TableLayout)findViewById(R.id.debtlist); 
    TableRow tr1 = new TableRow(this); 
    TextView textview = new TextView(this); 

    for(int i=0; i<stopper; i++) 
    { 

     tr1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); 
     tr1.setId(i); 

     textview.setText("" + i); 
     tr1.addView(textview); 
     tl.addView(tr1, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); 

     tr1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT)); 
     tr1.setId(i); 

    } 

    trigger++; 
} 
}

我有一個（基本）空白.XML一起工作：

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/debtlist" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

</TableLayout>

如果有人有任何更有效的方法來獲取基於用戶輸入的數據量顯示的4X1-10組TextViews，請讓我知道。

而且我使用API級12

在日誌中：

ClassCastException異常：android.app.ActionBar $的LayoutParams不能轉換到android.widget.LinearLayout $的LayoutParams

表示您正在導入ActionBar.LayoutParams用於將LayoutParams設置爲TableLayout和按鈕，因此使用LinearLayout.LayoutParams作爲：

for(int i=0; i<stopper; i++) 
    { 

    tr1.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, 
                LayoutParams.WRAP_CONTENT)); 
     //..... 
    tr1.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                LayoutParams.WRAP_CONTENT))); 
    tr1.setId(i); 

    }

仍然只有垂直或水平取決於我如何設置LL。 – jpgerb

因爲您正在使用表佈局和充氣ActionBar線性佈局的上下文，您正在獲取類轉換異常。

java.lang.ClassCastException：android.app.ActionBar $的LayoutParams不能轉換到android.widget.LinearLayout $的LayoutParams

是有辦法4列每行的X條記錄？

爲此使用自定義佈局並使用它。

for(int i=0; i<stopper; i++) 
    { 

     // Inflate your row "template" and fill out the fields. 
    TableRow row = (TableRow)LayoutInflater.from(context).inflate(R.layout.attrib_row, null); 
    ((TextView)row.findViewById(R.id.attrib_name)).setText(b.NAME); 
    ((TextView)row.findViewById(R.id.attrib_value)).setText(b.VALUE); 
    table.addView(row); 

    }
