tab 转换图片步骤
第一步获取资源图片
Drawable a2=getResources().getDrawable(R.drawable.icon_tab_discovery_normal);
第二步 得到图片大小
a2.setBounds(0, 0,a2.getMinimumWidth(),a2.getMinimumHeight());
第三步改变图片
R1.setCompoundDrawables(null, a2, null, null);
1 //得到资源文件 2 a0=getResources().getDrawable(R.drawable.icon_tab_hp_normal); 3 b0=getResources().getDrawable(R.drawable.icon_tab_hp_pressed); 4 a1=getResources().getDrawable(R.drawable.icon_tab_video_normal); 5 b1=getResources().getDrawable(R.drawable.icon_tab_video_pressed); 6 a2=getResources().getDrawable(R.drawable.icon_tab_discovery_normal); 7 b2=getResources().getDrawable(R.drawable.icon_tab_discovery_pressed); 8 a3=getResources().getDrawable(R.drawable.icon_tab_my_normal); 9 b3=getResources().getDrawable(R.drawable.icon_tab_my_pressed);
//设置图片尺寸
1 a0.setBounds(0,0 , a0.getMinimumWidth(), a0.getMinimumHeight()); 2 b0.setBounds(0,0 , b0.getMinimumWidth(), b0.getMinimumHeight()); 3 a1.setBounds(0,0 , a1.getMinimumWidth(), a1.getMinimumHeight()); 4 b1.setBounds(0,0 , b1.getMinimumWidth(), b1.getMinimumHeight()); 5 a2.setBounds(0,0 , a2.getMinimumWidth(), a2.getMinimumHeight()); 6 b2.setBounds(0,0 , b2.getMinimumWidth(), b2.getMinimumHeight()); 7 a3.setBounds(0,0 , a3.getMinimumWidth(), a3.getMinimumHeight()); 8 b3.setBounds(0,0 , b3.getMinimumWidth(), b3.getMinimumHeight());
//设置更改的图片
1 R1.setCompoundDrawables(null, a0, null, null); 2 R2.setCompoundDrawables(null, a1, null, null); 3 R3.setCompoundDrawables(null, a2, null, null); 4 R4.setCompoundDrawables(null, a3, null, null);
//设置更改的颜色、
1 R1.setTextColor(getResources().getColor(R.color.bottom)); 2 R2.setTextColor(getResources().getColor(R.color.bottom)); 3 R3.setTextColor(getResources().getColor(R.color.bottom)); 4 R4.setTextColor(getResources().getColor(R.color.bottom));
