Android動態佈局

每次都忘記，記下來，以後方便查找，代碼是從現在的項目中Copy出來的，先來個relativeLayout的

private void setListPath(Context context, RelativeLayout footerRelativeLayout, String ButtonText) {
 if (flagAddFooterGuide) {
 // 我的音樂按鈕
 ImageView myMusic = new ImageView(context);
 myMusic.setImageResource(R.drawable.style1_mymusic);
 myMusic.setOnClickListener(new OnClickListener() {
 @Override
 public void onClick(View v) {
 // TODO Auto-generated method stub
 ((MyMusicActivity) myContext).setSdCardFlag(false);
 ((MyMusicActivity) myContext).onCreate(null);
 }

 });
 myMusic.setId(1); // 設置ID爲1

 ImageView myStorage = new ImageView(context);
 myStorage.setImageResource(R.drawable.style1_mymusic_usbstore);
 myStorage.setOnClickListener(new OnClickListener() {

 @Override
 public void onClick(View v) {
 // TODO Auto-generated method stub
 // 設置ListView爲顯示
 ((MyMusicActivity) myContext).setlistViewLinearLayoutVisible(false);
 // GalleryVisible爲隱藏
 ((MyMusicActivity) myContext).setGalleryVisible(true);
 }

 });

 myStorage.setId(2); // 設置id爲2
 // 設置本地當前目錄的按鈕
 MyImageButton myImageButtonFolderNow = new MyImageButton(context, R.drawable.style1_mymusic_details, ButtonText);

 RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
 ViewGroup.LayoutParams.WRAP_CONTENT);
 lp1.addRule(RelativeLayout.ALIGN_PARENT_LEFT);

 RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
 ViewGroup.LayoutParams.WRAP_CONTENT);
 lp2.addRule(RelativeLayout.RIGHT_OF, 1);//在控件ID爲1的控件的右邊

 RelativeLayout.LayoutParams lp3 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
 ViewGroup.LayoutParams.WRAP_CONTENT);
 lp3.addRule(RelativeLayout.RIGHT_OF, 2);

 footerRelativeLayout.addView(myMusic, lp1);
 footerRelativeLayout.addView(myStorage, lp2);

 // 播放按鈕
 MyImageButton myImageButtonPlay = new MyImageButton(context, R.drawable.mymusic_button_pause_backgroud, "播放");

 footerRelativeLayout.addView(myImageButtonFolderNow, lp3);

 myImageButtonPlay.setId(4);
 RelativeLayout.LayoutParams lp4 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
 ViewGroup.LayoutParams.WRAP_CONTENT);

 lp4.addRule(RelativeLayout.LEFT_OF, 5);

 // 隨機按鈕
 MyImageButton myImageButtonPlayRandom = new MyImageButton(context, R.drawable.mymusic_button_play_random, "隨機開");

 myImageButtonPlayRandom.setId(5);
 RelativeLayout.LayoutParams lp5 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
 ViewGroup.LayoutParams.WRAP_CONTENT);
 lp5.addRule(RelativeLayout.LEFT_OF, 6);

 // 歌詞按鈕
 MyImageButton myImageButtonLyric = new MyImageButton(context, R.drawable.mymusic_button_lyric, "LRC歌詞");
 myImageButtonLyric.setId(6);
 RelativeLayout.LayoutParams lp6 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
 ViewGroup.LayoutParams.WRAP_CONTENT);
 lp6.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
 // 加入
 footerRelativeLayout.addView(myImageButtonLyric, lp6);
 footerRelativeLayout.addView(myImageButtonPlayRandom, lp5);
 footerRelativeLayout.addView(myImageButtonPlay, lp4);
 flagAddFooterGuide = false;

再來個LinearLayout的

^?[Copy to clipboard]Download zuiniuwang.java

super.onCreate(icicle);
 LinearLayout layout = new LinearLayout(this);
 layout.setOrientation(LinearLayout.VERTICAL);

 btn = new Button(this);
 btn.setId(101);
 btn.setText("test looper");
 btn.setOnClickListener(this);
 LinearLayout.LayoutParams param =
 new LinearLayout.LayoutParams(100,50);
 param.topMargin = 10;
 layout.addView(btn, param);

 btn2 = new Button(this);
 btn2.setId(102);
 btn2.setText("exit");
 btn2.setOnClickListener(this);
 layout.addView(btn2, param);

 tv = new TextView(this);
 tv.setTextColor(Color.WHITE);
 tv.setText("");
 //其中 FP 是final int FP=LinearLayout.LayoutParams.FILL_PARENT;
 //final int WC = LinearLayout.LayoutParams.WRAP_CONTENT;
 LinearLayout.LayoutParams param2 =
 new LinearLayout.LayoutParams(FP, WC);
 param2.topMargin = 10;
 param2.setMargins(0, 0, 5, 0); //參數分別是(int left, int top, int right, int bottom)
 layout.addView(tv, param2);
 setContentView(layout);

 

一定要記住，創建的Parameter addview時，一定是這個子控件的參數，而不是這個容器本身的參數，這個相當重要，我在此處浪費了不少時間。如果需要對本Layout加入上參數可以 layout.setLayoutParams( XXX params) 和 layout.setXXX 便可。
