TextView實現菜單項

開發中常常須要實現圖標配文字的菜單項，如圖

通常的實現思路是每個菜單項由一個LinearLayout包裹一個ImageView和一個TextView實現。可是這樣作會增長佈局的嵌套層數，另外一個實現思路是經過TextView的drawableLeft屬性來實現此效果，經過代碼設置邊距和圖片大小。
代碼以下:

`   TextView tvScanCode = (TextView) headerView.findViewById(R.id.tv_scan_code);
    Drawable drawableScan = ContextCompat.getDrawable(this, R.drawable.ic_nav_scan);
    drawableScan.setBounds(0, 0, 40, 40);
    tvScanCode.setCompoundDrawables(drawableScan, null, null, null);

    TextView tvFeedback = (TextView) headerView.findViewById(R.id.tv_feed_back);
    Drawable drawableFeed = ContextCompat.getDrawable(this, R.drawable.ic_nav_deedback);
    drawableFeed.setBounds(0, 0, 40, 40);
    tvFeedback.setCompoundDrawables(drawableFeed, null, null, null);

    TextView tvAbout = (TextView) headerView.findViewById(R.id.tv_about);
    Drawable drawableAbout = ContextCompat.getDrawable(this, R.drawable.ic_nav_about);
    drawableAbout.setBounds(0, 0, 40, 40);
    tvAbout.setCompoundDrawables(drawableAbout, null, null, null);`
