Android Dialog 系統樣式講解及透明背景

AlertDialog.Builder builder = new AlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_TRADITIONAL);//傳統主題

 

AlertDialog.Builder builder = new AlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_HOLO_DARK);//使用深色背景 主題

 

 

 

AlertDialog.Builder builder = new AlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_HOLO_LIGHT);//使用淺色背景 主題

 

 

AlertDialog.Builder builder = new AlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_DEVICE_DEFAULT_DARK);//使用默認設備 深色主題

 

 

AlertDialog.Builder builder = new AlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);//使用默認設備 淺色主題

 

//自定義布局 

View layout = getActivity().getLayoutInflater().inflate(R.layout.mydialog,null);

AlertDialog.Builder dialog = new AlertDialog.Builder(DialogActivity.this,AlertDialog.THEME_DEVICE_DEFAULT_DARK);

final AlertDialog dialog = builder.create();

dialog.setView(layout);

//透明

Window window = dialog.getWindow(); 

WindowManager.LayoutParams lp = window.getAttributes();

lp.alpha = 0.9f;

window.setAttributes(lp);

。。。

dialog.show();
