我面臨一個場景,其中我的main.xml的主要層次結構用XML編寫,但主數據來自服務器,所以我需要在運行時組合佈局。以編程方式創建佈局的最佳方式的提示
請看看這screenshot以更好地瞭解我的情況。
我將有一個滾動視圖,然後在它下面,一個線性佈局。我在我的java類中檢索這個佈局並創建一個新的線性佈局,這樣我就可以創建新的TextViews和Buttons,就像我在LinearLayout 2中繪製的那樣。最終結果與我預期的並不相符,而且我確實不知道該如何完成這個。
的代碼是:
LinearLayout ll = (LinearLayout) findViewById(R.id.linearLayoutOffers); //this is the LinearLayout2 in SS
//Creating the container that will have one business.
LinearLayout containerMain = new LinearLayout(this);
containerMain.setOrientation(LinearLayout.VERTICAL);
containerMain.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
containerMain.setGravity(Gravity.CENTER);
LinearLayout container1 = new LinearLayout(this);
container1.setOrientation(LinearLayout.HORIZONTAL);
container1.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
container1.setGravity(Gravity.CENTER);
container1.setWeightSum(2);
LinearLayout container2 = new LinearLayout(this);
container2.setOrientation(LinearLayout.HORIZONTAL);
container2.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
container2.setGravity(Gravity.CENTER);
container2.setWeightSum(1);
LinearLayout container3 = new LinearLayout(this);
container3.setOrientation(LinearLayout.HORIZONTAL);
container3.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
container3.setGravity(Gravity.CENTER);
container3.setWeightSum(1);
TextView offerTitle = new TextView(this);
offerTitle.setText(pOfferTitle);
offerTitle.setTextSize(14);
//offerTitle.setPadding(10, 0, 10, 0);
offerTitle.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1));
Button redeemButton = new Button(this);
redeemButton.setText("Usar");
redeemButton.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1));
//redeemButton.setPadding(10, 0, 10, 0);
redeemButton.setTextSize(14);
container1.addView(offerTitle);
container1.addView(redeemButton);
TextView mAddress = new TextView(this);
mAddress.setText(pAddress);
mAddress.setTextSize(14);
//mAddress.setPadding(10, 0, 10, 0);
mAddress.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1));
container2.addView(mAddress);
TextView expiryDate = new TextView(this);
expiryDate.setText(pExpiryDate);
expiryDate.setTextSize(14);
//expiryDate.setPadding(10, 0, 10, 0);
offerTitle.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 0.6f));
Button detailsButton = new Button(this);
detailsButton.setText("Detalhes");
detailsButton.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 0.4f));
//detailsButton.setPadding(30, 0, 0, 0);
detailsButton.setTextSize(14);
container3.addView(expiryDate);
container3.addView(detailsButton);
containerMain.addView(container1);
containerMain.addView(container2);
containerMain.addView(container3);
ll.addView(containerMain);

ListView中的一行可以包含TextView,Button和Image嗎?因爲我能找到的每一個例子都只是在這一行中添加純文本。 – 2012-02-06 09:56:26
當然可以。您的ListView適配器中的getView方法可以返回您希望它返回的任何佈局。有一個很好的例子,說明如何從ListView適配器開始:http://www.mkyong.com/android/android-listview-example/ – Thommy 2012-02-06 10:38:32
