我叫帕維爾。如何在java中以編程方式製作表格佈局?

我想有佈局是這樣的:

Layout

我想在Java中的佈局,因爲按鈕的數量會發生變化。正方形是按鈕。 佈局包括:

<LinearLayout> 
    <Button/> 
    <TableLayout> 
     <TableRow> 
      <Button1/> 
      <Button2/> 
     </TableRow> 
     <TableRow> 
      <Button3/> 
      <Button4/> 
     </TableRow> 
    <TableLayout> 
    <Button/> 
</LinearLayout> 

我的代碼:

@Override 
protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 

     int title = getIntent().getIntExtra(KEY, MainScreen.CHOICE_COMPUTER); 

     switch(title) 
     { 
      case MainScreen.CHOICE_COMPUTER: 
       setTitle("Computer"); 
       break; 
      case MainScreen.CHOICE_LAPTOP: 
       setTitle("Laptop"); 
       break; 
      case MainScreen.CHOICE_TV: 
       setTitle("Tv"); 
       break; 
      case MainScreen.CHOICE_FRIDGE: 
       setTitle("Fridge"); 
       break; 
     } 

     LinearLayout choiceLayout = new LinearLayout(this); 
     choiceLayout.setOrientation(LinearLayout.VERTICAL); 
     choiceLayout.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); 
     choiceLayout.setPadding(15, 15, 15, 15); 
     choiceLayout.setGravity(Gravity.CENTER); 
     choiceLayout.setBackgroundResource(R.drawable.background); 

     button1 = new Button(this); 
     LinearLayout.LayoutParams buttonParameters = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 
     buttonParameters.setMargins(50, 20, 50, 70); 
     button1.setLayoutParams(buttonParameters); 
     button1.setGravity(Gravity.CENTER); 
     button1.setPadding(10, 10, 10, 10); 
     button1.setBackgroundResource(R.drawable.background_button); 
     switch(title) 
     { 
      case MainScreen.CHOICE_COMPUTER: 
       button1.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.icon_button_computer, 0, 0); 
       button1.setText("Computer"); 
       break; 
      case MainScreen.CHOICE_LAPTOP: 
       button1.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.icon_button_laptop, 0, 0); 
       button1.setText("Laptop"); 
       break; 
      case MainScreen.CHOICE_TV: 
       button1.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.icon_button_tv, 0, 0); 
       button1.setText("Tv"); 
       break; 
      case MainScreen.CHOICE_FRIDGE: 
       button1.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.icon_button_fridge, 0, 0); 
       button1.setText("Fridge"); 
       break; 
     } 

     TableLayout choiceTableLayout = new TableLayout(this); 
     TableLayout.LayoutParams param1 = new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); 
     param1.setMargins(20, 20, 20, 20); 
     choiceTableLayout.setLayoutParams(param1); 
     choiceTableLayout.setGravity(Gravity.CENTER); 
     choiceTableLayout.setStretchAllColumns(true); 

     TableLayout.LayoutParams rowLayout = new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 

     TableRow row1 = new TableRow(this); 
     TableRow row2 = new TableRow(this); 

     row1.setLayoutParams(rowLayout); 
     row2.setLayoutParams(rowLayout); 

     LinearLayout.LayoutParams buttonLayout = new LinearLayout.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1.0f); 
     buttonLayout.setMargins(10, 10, 10, 10); 

     buttonOption1 = new Button(this); 
     buttonOption1.setLayoutParams(param1); 
     buttonOption1.setId(objectCounter++); 
     Log.d("Counter: ", Integer.toString(objectCounter)); 
     Log.d("ID", Integer.toString(buttonOption1.getId())); 
     buttonOption1.setGravity(Gravity.CENTER); 
     buttonOption1.setBackgroundResource(R.drawable.option_off_background_button); 
     buttonOption1.setTextSize(19); 
     buttonOption1.setTextColor(getResources().getColor(R.color.color_text_button)); 
     buttonOption1.setText("Off"); 
     buttonOption1.setBackgroundResource(R.drawable.option_off_background_button); 
     buttonOption1.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.option1, 0, 0); 

     buttonOption2 = new Button(this); 
     buttonOption2.setLayoutParams(buttonLayout); 
     buttonOption2.setId(objectCounter++); 
     buttonOption2.setGravity(Gravity.CENTER); 
     buttonOption2.setBackgroundResource(R.drawable.option_background_button); 
     buttonOption2.setTextSize(19); 
     buttonOption2.setTextColor(getResources().getColor(R.color.color_text_button)); 
     buttonOption2.setText(R.string.button_text_option2); 
     buttonOption2.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.option2, 0, 0); 

     buttonOption3 = new Button(this); 
     buttonOption3.setLayoutParams(buttonLayout); 
     buttonOption3.setId(objectCounter++); 
     buttonOption3.setGravity(Gravity.CENTER); 
     buttonOption3.setBackgroundResource(R.drawable.option_background_button); 
     buttonOption3.setTextSize(19); 
     buttonOption3.setTextColor(getResources().getColor(R.color.color_text_button)); 
     buttonOption3.setText(R.string.button_text_option3); 
     buttonOption3.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.option3, 0, 0); 

     buttonOption4 = new Button(this); 
     buttonOption4.setLayoutParams(buttonLayout); 
     buttonOption4.setId(objectCounter++); 
     buttonOption4.setGravity(Gravity.CENTER); 
     buttonOption4.setBackgroundResource(R.drawable.option_background_button); 
     buttonOption4.setTextSize(19); 
     buttonOption4.setTextColor(getResources().getColor(R.color.color_text_button)); 
     buttonOption4.setText(R.string.button_text_option4); 
     buttonOption4.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.option4, 0, 0); 

     buttonSend = new Button(this); 
     LinearLayout.LayoutParams buttonSendParameter = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 
     buttonSendParameter.gravity = Gravity.RIGHT|Gravity.BOTTOM; 
     buttonSend.setLayoutParams(buttonSendParameter); 
     buttonSend.setId(objectCounter++); 
     buttonSend.setGravity(Gravity.RIGHT|Gravity.BOTTOM); 
     buttonSend.setBackgroundResource(R.drawable.background_button); 
     buttonSend.setBackgroundResource(R.drawable.button_send); 

     row1.addView(buttonOption1); 
     row1.addView(buttonOption2); 
     row2.addView(buttonOption3); 
     row2.addView(buttonOption4); 
     choiceTableLayout.addView(row1); 
     choiceTableLayout.addView(row2); 
     choiceLayout.addView(button1); 
     choiceLayout.addView(choiceTableLayout); 
     choiceLayout.addView(buttonSend); 

     setContentView(choiceLayout); 

     buttonOption1.setOnClickListener(this); 
     buttonOption2.setOnClickListener(this); 
     buttonOption3.setOnClickListener(this); 
     buttonOption4.setOnClickListener(this); 
     buttonSend.setOnClickListener(this); 
    } 

錯誤蝕:

12月9日至21日:41:09.062:E/AndroidRuntime(758):java.lang中。 ArithmeticException:除以零

我認爲它與拉伸列連接。

我的問題是:如何糾正這在Android中使佈局如圖片?

如何在TableLayout中爲按鈕創建佈局?如果不將佈局設置爲TableLayout內的按鈕,則不會出現錯誤。 – Pawel

在哪一行發生錯誤異常 – Ronnie

改變這一行

LinearLayout.LayoutParams buttonLayout = 
      new LinearLayout.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1.0f); 

TableRow.LayoutParams buttonLayout = 
      new TableRow.LayoutParams(LayoutParams.FILL_PARENT, 
             LayoutParams.WRAP_CONTENT); 

當你在拉伸所有領域,我覺得沒有必要爲重參數。它與FILL_PARENT相同

問題解決了。元素的佈局應該有父級的佈局。 – Pawel

我改變了其餘的,不僅這一行。 – Pawel

謝謝你的回答:)。 – Pawel
