Android：以編程方式將ListView設置爲對話內容

Question

我在做什麼錯？我收到一個沒有內容的空白對話框。代碼：

@Override 
protected Dialog onCreateDialog(int id, Bundle b) { 
    LayoutInflater inflater = (LayoutInflater) this.getSystemService(this.LAYOUT_INFLATER_SERVICE); 
    switch(id) { 
     case DIALOG_COLOR_MODE: 
     { 
      LinearLayout layout = new LinearLayout(this); 
      LinearLayout.LayoutParams lllp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); 
      layout.setLayoutParams(lllp); 

      ListView modeList = new ListView(this); 
      Dialog dialog = new Dialog(this); 

      TextView layoutBright = new TextView(this); 
      TextView layoutNormal = new TextView(this); 

      layoutBright.setText("Bright Mode"); 
      layoutNormal.setText("Normal Mode"); 

      modeList.addFooterView(layoutBright); 
      modeList.addFooterView(layoutNormal); 

      layout.addView(modeList); 

      dialog.setContentView(layout); 

      return dialog; 
     } 
[...]

解決方案：

Dialog dialog = new Dialog(this); 
AlertDialog.Builder builder = new AlertDialog.Builder(this); 
builder.setTitle("Select Color Mode"); 

ListView modeList = new ListView(this); 
String[] stringArray = new String[] { "Bright Mode", "Normal Mode" }; 
ArrayAdapter<String> modeAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, stringArray); 
modeList.setAdapter(modeAdapter); 

builder.setView(modeList); 
dialog = builder.create(); 

但說實話，用AlertDialog.Builder.setItems（）是這一個更好的解決方案。
