TabHost每个选项卡的字体颜色怎么修改

Answer 1

TabWidget tabWidget = tabHost.getTabWidget();								//获取TabHost的头部	
		
	    for (int i=0; i<tabWidget.getChildCount(); i++){							//循环每个tabView
	    	View view = tabWidget.getChildAt(i);									//获取tabView项	    	
	    	view.setContentDescription(Integer.toString(i+1));
	    	view.getLayoutParams().height = (int) (view.getLayoutParams().height / 1.2);
	    	
	    	//ImageView imageView = (ImageView) view.findViewById(android.R.id.icon);	//获取当前选择的图标
	    	//TextView textView = (TextView) view.findViewById(android.R.id.title);	//获取textView控件	 
	    	//imageView.setImageDrawable(getResources().getDrawable(android.R.drawable.ic_menu_slideshow)); //改变我们需要的图标
	    	
	    	
	    	switch (i) {
				case 0:{
					view.setBackgroundResource(R.drawable.menu_1_selector);
					break;
				}				
				case 1:{
					view.setBackgroundResource(R.drawable.menu_2_selector);
					break;
				}				
				case 2:{
					view.setBackgroundResource(R.drawable.menu_3_selector);
					break;
				}		
				case 3:{
					view.setBackgroundResource(R.drawable.menu_4_selector);
					break;
				}
			}
	    	
	    	/*
	    	if(i == 0){
	    		view.setBackgroundResource(R.drawable.tab_1_selector);				//设置背景以后重新设置背景图片	    		
	    	}else if(i == 1){
	    		view.setBackgroundResource(R.drawable.tab_2_selector);
	    	}else if(i == 2){
	    		view.setBackgroundResource(R.drawable.tab_3_selector);
	    	}

	    
	    	TextView textView = (TextView) view.findViewById(android.R.id.title);	//获取textView控件	    	
	    	RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) textView.getLayoutParams(); 
           
	    	
            params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 0); 					//取消文字底边对齐  
            params.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);   //设置TextView的文字居中       
           
           
            textView.getPaint().setFakeBoldText(true);								//字体加粗     
	    	if (tabHost.getCurrentTab() == i) {  									//如果当前的标签为选中,则将字体放大,并改变其颜色
	    		textView.setTextSize(16);
	    		textView.setTextColor(Color.parseColor("#ff6600"));  				//选中时的字体颜色          	
            } else {            	
            	textView.setTextSize(14);
            	textView.setTextColor(Color.parseColor("#FFFFFF"));
            }
