[英]When RelativeLayout is into a ScrollView, moving TextView with touch doesn't work correctly
[英]Center Gravity for TextView doesn't work on xxhdpi in RelativeLayout
我有方形背景的TextViews,其數字每秒出現一次。 我使用正方形圖像作為背景,並將文本重心設置為使數字居中。 在xxhdpi手機上不起作用。 如何將數字居中?
這是代碼:
displayingCell = new TextView(MyActivity.this);
displayingCell.setTypeface(null, Typeface.BOLD);
displayingCell.setTextSize(mySize);
displayingCell.setTextColor(Color.BLACK);
displayingCell.setGravity(Gravity.CENTER);
displayingLayoutParam = new RelativeLayout.LayoutParams(diameter, diameter);
displayingLayoutParam.setMargins(marginLeft, marginTop, 0, 0);
displayingCell.setLayoutParams(displayingLayoutParam);
displayingCell.setBackground(myImage);
displayingCell.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
嘗試刪除
displayingLayoutParam.setMargins
並添加
displayingLayoutParam.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
如果此問題僅出現在xxhdpi設備上,則可以檢查設備的運行時並將marginbottom
設置為marginbottom
文本。 我在我的工具欄文本中添加了邊距。 希望你能得到這個把戲
switch (getResources().getDisplayMetrics().densityDpi) {
case DisplayMetrics.DENSITY_HIGH:
Log.d("density:", "high");
toolbar.setTitleMarginStart(160);
break;
case DisplayMetrics.DENSITY_XHIGH:
// ...
Log.d("density:", "xhigh");
toolbar.setTitleMarginStart(200);
break;
case DisplayMetrics.DENSITY_XXHIGH:
Log.d("density:", "xxhigh");
toolbar.setTitleMarginStart(380);
break;
}
