Android动态布局
每次都忘记，记下来，以后方便查找，代码是从现在的项目中Copy出来的，先来个relativeLayout的 private void setListPath(Context context, RelativeLayout footerRelativeLayout, String ButtonText) { if (flagAddFooterGuide) { // 我的音乐按钮 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); // 设置ID为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 // 设置ListView为显示 ((MyMusicActivity) myContext).setlistViewLinearLayoutVisible(false); // GalleryVisible为隐藏 ((MyMusicActivity) myContext).setGalleryVisible(true); } }); myStorage.setId(2); // 设置id为2 // 设置本地当前目录的按钮 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为1的控件的右边 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); // 播放按钮 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); // 随机按钮 MyImageButton myImageButtonPlayRandom = new MyImageButton(context, R.drawable.mymusic_button_play_random, "随机开"); myImageButtonPlayRandom.setId(5); RelativeLayout.LayoutParams lp5 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); lp5.addRule(RelativeLayout.LEFT_OF, 6); // 歌词按钮 MyImageButton myImageButtonLyric = new MyImageButton(context, R.drawable.mymusic_button_lyric, "LRC歌词"); 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; ?[Copy to clipboard] Downloadzuiniuwang.java 再来个LinearLayout的 ?[Copy to clipboard] Downloadzuiniuwang.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); //参数分别是(int left, int top, int right, int bottom) layout.addView(tv, param2); setContentView(layout); 一定要记住，创建的Parameter addview时，一定是这个子控件的参数，而不是这个容器本身的参数，这个相当重要，我在此处浪费了不少时间。如果需要对本Layout加入上参数可以 layout.setLayoutParams( XXX params) 和 layout.setXXX 便可。 本文转自 最牛傻蛋 51CTO博客，原文链接：http://blog.51cto.com/zuiniuwang/720070，如需转载请自行联系原作者
