Activity
//得到高度 Display display = this.getWindowManager().getDefaultDisplay(); height = display.getHeight(); width = display.getWidth(); String url = "aa.doc"; //打开文件 this.setContentView(R.layout.show); lay_show = (LinearLayout) this.findViewById(R.id.show_layout); //设置阅读背景（平铺） Bitmap bitmap1 = BitmapFactory.decodeResource(getResources(), R.drawable.rebg); BitmapDrawable bd1 = new BitmapDrawable(bitmap1); bd1.setTileModeXY(TileMode.REPEAT , TileMode.REPEAT ); bd1.setDither(true); lay_show.setBackgroundDrawable(bd1); //添加线性参数 lp_show = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT); lp_show.height=height; lp_show.weight=width; TextView tv = new TextView(this); tv.setTextSize(14); tv.setTextColor(Color.WHITE); tv.setWidth(width); lay_show.addView(tv,lp_show); tv.setText(readDOC(url));
以上方法只能读取字符流，不能读取图片。
