android Toast文字加大

看到有人说用自定义的View,太麻烦了

private Toast mToast;private void showTip(final String str) {runOnUiThread(new Runnable() {@Overridepublic void run() {if (mToast == null) {mToast = Toast.makeText(getApplicationContext(), "",Toast.LENGTH_LONG);LinearLayout layout = (LinearLayout) mToast.getView();TextView tv = (TextView) layout.getChildAt(0);tv.setTextSize(25);}//mToast.cancel();mToast.setGravity(Gravity.CENTER, 0, 0);mToast.setText(str);mToast.show();}});}
