Question

小册子宽度与手机中的全宽相匹配，但在平板电脑上运行时却没有设置match_parent。请帮助我！代码在下面

final Snackbar mSnackbar = Snackbar.make(view, "", Snackbar.LENGTH_LONG);
LayoutInflater inflater = (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) mSnackbar.getView();
layout.setPadding(0,0,0,0);
TextView textView = (TextView) 
layout.findViewById(android.support.design.R.id.snackbar_text);
textView.setVisibility(View.INVISIBLE);
snackView = inflater.inflate(R.layout.snackbar_layout, null);
layout.addView(snackView, 0);

Answer 1

使用以下代码段在平板电脑横向模式中支持全宽：

Snackbar snackbar = Snackbar.make(view, "Sample Text", Snackbar.LENGTH_LONG)
                    .setAction("Sample Text", new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {

                        }
                    });
            (snackbar.getView()).getLayoutParams().width =ViewGroup.LayoutParams.MATCH_PARENT;;
            snackbar.show();

我认为这是平板电脑上snackbar的默认行为。有关更多信息look here

如果使用此主题：

//in this list we store the data
List adatok = [];

Future<void> getData(){
  databaseReference.getDocuments().then((QuerySnapshot snapshot) {
    snapshot.documents.forEach((f){
      data = f.data;
      adatok.add(data);
      print(adatok.length);
      print(adatok);
        }
      );
    }
  );
}

小吃店有边距和圆角。

要删除边距：

"Theme.MaterialComponents"

并删除圆角：

View viewInSnk = snkbr.getView();
ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams) snkbr.getView().getLayoutParams();
params.setMargins(0, 0, 0, 0);
snkbr.getView().setLayoutParams(params);

和形状：

viewInSnk.setBackgroundDrawable(getResources().getDrawable(R.drawable.snackbar_shape));

Answer 4

使用以下代码;

 Snackbar snackbar = Snackbar
                    .make(put_your_parent_layout_id, "Try again!", Snackbar.LENGTH_LONG)
                    .setAction("RETRY", new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                        }
                    });
            snackbar.setActionTextColor(Color.RED);
            View sbView = snackbar.getView();
            TextView textView = (TextView) sbView.findViewById(android.support.design.R.id.snackbar_text);
            textView.setTextColor(Color.YELLOW);
            snackbar.show();
