TableLayout에 동적으로 행을 추가하십시오.

Question

데이터베이스에서 내용을 가져 와서 테이블 레이아웃에 행을 추가하고 싶습니다. 아래 코드를 시도했지만 작동하지 않습니다. 나는, 데이타베이스 관련 업무에 대한 클래스 'ProductDatabase'을 만들어 ... 그리고 다른 활동에 아래의 코드를 사용하여 ...하지만 그 어떤 출력

ProductDatabase pData; //Database Class 
TableLayout mainTable; 
Cursor cr; 


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

    pData = new ProductDatabase(this); 
    mainTable = (TableLayout) findViewById(R.id.mainTable); 


} 

@SuppressWarnings("deprecation") 
@Override 
protected void onResume() { 
    super.onResume(); 
    pData.open(); 
    cr=pData.getDatabaseCursor(); //fetching cursor from Database Class 
    int index=1;  
     for (cr.moveToFirst(); !cr.isAfterLast(); cr.moveToNext()) { 
      TableRow tr=new TableRow(this); 
       tr.setId(1000+index); 
       tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); 

       TextView labelName=new TextView(this); 
       labelName.setId(2000+index); 
       labelName.setText(cr.getString(cr.getColumnIndex(ProductDatabase.KEY_NAME))); 
       labelName.setTextColor(Color.BLACK); 
       labelName.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); 
       tr.addView(labelName); 

       TextView labelBarcode=new TextView(this); 
       labelBarcode.setId(3000+index); 
       labelBarcode.setText(cr.getString(cr.getColumnIndex(ProductDatabase.KEY_BARCODE))); 
       labelBarcode.setTextColor(Color.BLUE); 
       labelBarcode.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); 
       tr.addView(labelBarcode); 

       TextView labelCost=new TextView(this); 
       labelCost.setId(4000+index); 
       labelCost.setText(cr.getString(cr.getColumnIndex(ProductDatabase.KEY_COST))); 
       labelCost.setTextColor(Color.BLUE); 
       labelCost.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); 
       tr.addView(labelCost); 

       mainTable.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); 

       index++; 

          } 
    pData.close(); 

} 

}

가 동적으로 행을 추가하려면 표시되지 TableLayout이 코드를 사용할 수

for (int i=0; i < 5; i ++) { 
     TableRow tr=new TableRow(this); 
     tr.setId(1000 + i); 

     TextView labelName=new TextView(this); 
     labelName.setId(2000 + i); 
     labelName.setText("Test"); 
     labelName.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT)); 
     tr.addView(labelName); 

     TextView labelBarcode=new TextView(this); 
     labelBarcode.setId(3000+i); 
     labelBarcode.setText("Test"); 
     labelBarcode.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT)); 
     tr.addView(labelBarcode); 

     TextView labelCost=new TextView(this); 
     labelCost.setId(4000+i); 
     labelCost.setText("Test"); 
     labelCost.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT)); 
     tr.addView(labelCost); 

     mainTable.addView(tr, new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT,TableLayout.LayoutParams.WRAP_CONTENT)); 

    } 

난 그냥 그것을 테스트하기 위해 조금 당신의 코드를 변경했습니다.

여기서 중요한 것은 LayoutParams에 영향을 미칩니다. 행을 추가 할 때 TableRow 및 TableLayout.LayoutParams 내에서보기에 TableRow.LayoutParams을 사용합니다.

//this layout parem for the alignment of the row 
    TableRow.LayoutParams rowParams = 
          new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, 0, 1f); 
       TableRow.LayoutParams itemParams = 
          new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, 
                TableRow.LayoutParams.MATCH_PARENT, 1f); 

       //making the loop for multiple table row 
       //start 
       for(int i=0;i<tid;i++){ 
       TableRow tr=new TableRow(this); 
       tr.setLayoutParams(rowParams); 
       j++; 
       TextView feel_sleep=new TextView(this); 
       TextView woke_up=new TextView(this); 
       TextView slept_min=new TextView(this); 
       //creating the add icon 
       ImageView icon_add=new ImageView(this); 
       icon_add.setBackgroundResource(R.drawable.icon_add); 

       //creating the delete icon 
       ImageView icon_delete=new ImageView(this); 
       icon_delete.setBackgroundResource(R.drawable.icon_delete); 

       LinearLayout icon_layout=new LinearLayout(this); 

       icon_layout.addView(icon_add); 
       icon_layout.addView(icon_delete); 


       TableRow.LayoutParams params = new TableRow.LayoutParams(
         LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); 
        params.gravity = Gravity.CENTER; 


       feel_sleep.setLayoutParams(itemParams); 
       woke_up.setLayoutParams(itemParams); 
       slept_min.setLayoutParams(itemParams); 
       icon_layout.setLayoutParams(params); 
       icon_layout.setId(j); 

       Logger.d("id for i:","**:"+i);  
       Logger.d("id for j:","**:"+j);  

       feel_sleep.setGravity(Gravity.CENTER); 
       woke_up.setGravity(Gravity.CENTER); 
       slept_min.setGravity(Gravity.CENTER); 


       feel_sleep.setText("00:00"); 
       woke_up.setText("00:00"); 

       tr.addView(feel_sleep); 
       tr.addView(woke_up); 
       tr.addView(slept_min); 
       tr.addView(icon_layout); 
    } 

    //this is the tablelayout id `enter code here` 
    table_layout.addView(tr);
