view_dialog_clause.xml

Fragment中调用showClauseDialog

private void showClauseDialog() {
        final View dialogView = LayoutInflater.from(getContext())
                .inflate(R.layout.view_dialog_clause,null);
        final Dialog clauseDialog = new android.support.v7.app.AlertDialog
                .Builder(getContext())
                .setView(dialogView)
                .show();
        final WindowManager.LayoutParams params = clauseDialog.getWindow().getAttributes();
        //获取屏幕分辨率
        DisplayMetrics metrics =getApplicationContext().getResources().getDisplayMetrics();
        int width = metrics.widthPixels;int height = metrics.heightPixels;
        //设置对话框大小
        params.width = Math.round(width*4/5);
        params.height = Math.round(height*4/5);
        clauseDialog.getWindow().setAttributes(params);
        clauseDialog.getWindow().setBackgroundDrawableResource(android.R.color.white);

        mWebView=dialogView.findViewById(R.id.webView);

        clauseDialog.show();
