Android小Tip

1,動態改變textView的顏色

String s = "這是" + "<font color='#FF6131'>" + "變色的" + "</font>" + "字";
textView.setText(Html.fromHtml(s));

2，全屏並設置透明欄

/**
 * 設置透明狀態欄，需要寫在設置佈局前，最好是在BaseActivity中寫
 */
private void setStatusBar() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        Window window = getWindow();
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        if (isStatusBarWhite()) {
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
        } else {
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
        }
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.setStatusBarColor(0);
    }
}

protected boolean isStatusBarWhite() {
    return false;
}
